Power Progression

Stage / Realm / Level	Chapter	Notes
Strong kobold girl	5–10	Noted as stronger than before and possibly the strongest female kobold in the tribe; capable enough that Ruger thinks she could knock him down in a few punches before his spell growth 5 7 10.
Dragonblood / dragonkin kobold transformation	65	Ruger transforms Aisijin and Big Silly Hum with dragonblood. Aisijin is frightened but trusts Ruger and follows his instructions through the spatial gate and into the dragonblood pit 65.
Common Tongue comprehension	79–83	Ka Liu casts a language comprehension spell on Aisijin and Big Silly Hum. Afterward, Aisijin can read books in the common tongue, though not always understand everything 79 83.
Strength Fighter	176	Aisijin drinks/uses a Fighter potion and condenses a Fighter Mark as a Strength Fighter. Her strength increases dramatically; in excitement, she casually throws Ruger’s stone bed 176.
Fighter advancement attempt	299	Aisijin drinks Ruger’s potion and falls asleep for an unusually long advancement process. Ruger and Big Silly Hum wait anxiously until her Fighter Mark changes significantly 299.
Advanced Nightmare/Dream-related Fighter	300	Aisijin awakens stronger, with a larger transformed Fighter Mark, touch-induced drowsiness, and a controllable sleep-like state. Ruger identifies her as connected to Nightmare World materials and later notes her as a special Dream Fighter 300 396.
Dreamsleep Fighter application	427–429	Aisijin identifies herself as a “Dreamsleep Fighter” and proposes using her drowsiness-infused fist to help an exhausted Ruger sleep. Ruger later accepts a punch when his weakened condition makes the ability effective 427 429.
Continued Strength Fighter growth	333, 413	Her strength continues increasing through training; she changes from a two-handed greatsword to a long-handled battle axe after suitable greatswords become difficult to find, and later displays notable speed while preparing food for Ruger 333 413.
Sleep control and Fighter Mark strengthening	646	Her Dragonkin instincts and Dreamsleep Fighter abilities sometimes make her sleep deeply even while working. She learns to resist the onset of sleep through willpower, strengthening her Fighter Mark; she still periodically needs long periods of rest 646.
Gradual mental-power growth	814	Ruger notes that Aisijin and Big Silly Hum’s mental power has slowly grown since their dragonblood transformations, gradually approaching their bloodline limits. This is not an established advancement into wizardry 814.
Changed deep-sleep condition and nightmare fluctuations	816, 819	Ruger investigates a change in her sleeping pattern after Little Regna begins sleeping beside her. He later senses intermittent concentrated nightmare power leaking from their room, but initially finds no clear explanation 816 819.
Tail growth and modest dragonblood improvement	850–852	Aisijin awakens with a dragon-like tail bearing unusual, flush pattern-like markings. Ruger confirms slightly stronger and purer dragon blood, but only a modest overall increase in power. He suspects a condition involving her nightmare aura and dragon blood within the dream Castle; Immanuel considers the change more likely beneficial than harmful 850 851 852.
Continuing unexplained dream development	960, 1015	Aisijin reports becoming enormous in a dream to attack and eat a winged, many-headed creature with Ruger’s help. Later, Ruger considers her mental-power aptitude especially notable but admits he no longer fully understands her condition or what Regna has guided her to eat. The reported dream transformation is not confirmed as a waking ability 960 1015.
Unsuccessful attempt to learn wizard meditation	1044	Aisijin secretly borrows the Meditation Method Ruger gave Nisote after buying Nisote Bubble Wine. Her attempt fails, leaving her distressed that she cannot become a Wizard like Ruger; no wizard advancement is established 1044.

Background / History

Aisijin first appears as a taller dog-headed kobold girl who tells Ruger about the tribe’s new master, Gray Longneck Saint Lord. Her speech is halting and often reversed, but she is one of the few kobolds able to communicate with Ruger meaningfully 2.

Before Ruger gains power, Aisijin often shares her hard-won food with him, despite that going against ordinary kobold instincts. She learns that Ruger likes cooked food and brings him charred meat, partly to please him and partly because she wants to try something new herself 6 28.

Aisijin remains tied to the tribe’s dangerous master-changing cycle. She reports the replacement of Gray Longneck by Blackclaw Lord, later the return of Gray Longneck, and the discovery of Blackclaw’s disappearance amid a large amount of blood 5 14 28.

Her closest early bond besides Ruger is with Old Gold Tooth. When Old Gold Tooth is afflicted by glowing light strands, Aisijin urgently seeks help and guides Ruger and Big Silly Hum to him. Ruger notes that her anxiety is unlike her usual fierce response to threats 12 13.

Aisijin helps search for the black fruit connected to Big Silly Hum’s transformation and later leads Ruger toward its source. Ruger sees her effort as courageous and tied to her hope of saving Old Gold Tooth and becoming dragon-descended 20 42 43.

After Old Gold Tooth’s successful transformation, Aisijin tells Ruger about dark elf slave-catchers capturing kobolds and trapping Bald Tooth near the Holy Lord’s cave 50.

Ruger later transforms Aisijin and Big Silly Hum into dragonblood kobolds using dragonblood. After leaving the tribe, they spend much of their time in Ruger’s Abyss Bedroom space, where they adapt to the wider world, read novels, cultivate plants, cook, spar, and train 65 79 83 171 192.

During their adaptation to city life, Aisijin and Big Silly Hum participate in an arena bout against an agile underground beast. Their coordination has improved since their previous battle, and the experience helps them understand the limits of their extraordinary healing abilities. Afterward, they become more diligent and less restrained in their sparring 95 102.

As the Bedroom Space develops, Aisijin becomes increasingly responsible for its daily management. She helps guard its facilities, changes magic stones on the operating platform, assists the spirit furs, oversees cultivation and food preparation, and helps organize the newly built inn before its opening 410 533 554.

She continues helping to provision the space, going out with the others to catch fish and bringing their catch back through Ruger’s spatial gate 563. Her Dreamsleep Fighter abilities also create a practical need for occasional long rests. Shazhang formerly took her to sleep among the rocks; Serious Mouse later provides a proper place for her at the inn 646.

When Ruger describes Little Regna as more or less his child, Aisijin compares their relationship to her own bond with Old Gold Tooth. Ruger recalls that Old Gold Tooth cared for her despite the tribe’s poverty, treating their unusual connection as something between friendship and a father–daughter relationship. Old Gold Tooth also gave her a name while telling her stories; apart from Ruger, she had been the tribe’s only named kobold 670.

Little Regna becomes Aisijin’s regular sleeping companion, sometimes curling up in her arms. During Ruger’s prolonged research, Aisijin passes through three sleepy periods. Ruger later notices that her deep sleep has changed since Regna joined the household and investigates, initially detecting only her longstanding faint nightmare aura. On a subsequent occasion, concentrated nightmare power intermittently leaks from their room 695 813 816 819.

Aisijin eventually awakens with an unfamiliar tail and is frightened enough to remain in her room. Her companions gather dishes outside the door to tempt her out, while Tuzel proposes using his Miserly Spell to make wasting the food unbearable. She opens the door tearful and drooling, and a shared feast quickly distracts her from her distress 850 851.

At the meal, Aisijin reveals that she has repeatedly entered an immense Castle in her dreams since becoming a Dreamsleep Fighter. Little Regna can enter those dreams and guide her, helping her avoid danger and explore rather than wander lost. Ruger identifies the Castle, rather than Regna herself, as the unresolved anomaly behind the situation. He consults Immanuel about the physical change and comes to regard it as a possible opportunity, although its precise cause remains uncertain 851 852 853.

Aisijin continues her cultivation and cooking duties afterward. She keeps the Bedroom Space’s time records, helps grow materials for Ruger’s spirit-fur research, and joins the group with their soup pot for a meal in another world. She also looks after the Beast-Eared Witch, who later asks to thank her personally for her care and cooking 875 939 952 961.

Despite her continued dream-related development, Aisijin privately attempts to follow Ruger into wizardry. She uses the Silver Moon Coins he gave her to buy Nisote Bubble Wine and secretly borrows Nisote’s Meditation Method. The attempt fails, and she confesses her disappointment to Ruger 1015 1044.

Appearance

Aisijin begins as a sturdy female kobold, taller and stronger than Ruger in his early days. After her dragonblood transformation, she is repeatedly described as a tall, intimidating dragonblood/dragonborn kobold whose appearance can make outsiders nervous 5 10 83.

• Sturdy build and broad shoulders 10
• Sparse kobold fur, including several tufts Ruger considers attractive by kobold standards 10
• Stronger than most female kobolds in the tribe 10
• Later becomes a tall dragonblood/dragonborn kobold with a more imposing presence 65 83
• Continues to grow taller after becoming a dragonblood kobold and a Fighter 288
• Usually wears boots outside the Bedroom Space but removes them inside to avoid damaging them 396
• Wears a small apron she altered herself while cooking 557
• Carries a small cloth pouch, originally sewn by Daisy, for magic stones and other small items 410
• Later grows a dragon-like tail with markings that resemble scales at a distance but lie flush against the skin like patterns. These markings do not resemble the tail of the wingless Hybrid Dragon whose blood Ruger used for her original transformation 850 851
• Initially wears a loose robe in an unsuccessful attempt to conceal the new tail; its tip moves when she enjoys her food 852
• Her tail remains visible swaying beneath her robe in later appearances 1044
• Regular applications of Ruger’s Spirit Fur Nourishment leave her fur glossy, silky, and slightly spiritual, eliminating her old shedding troubles 954

Personality

Aisijin is unusual among kobolds because she can form sincere bonds, share food, and show curiosity beyond immediate survival. Ruger considers her a true friend, not merely someone repaying a debt, because ordinary kobolds do not reliably understand gratitude 6.

She is simple-minded but not stupid. Ruger repeatedly distinguishes her from ordinary kobolds, and Old Gold Tooth’s stories imply that Aisijin is a rare intelligent kobold born among a cursed race 2 14.

She is loyal, trusting, and emotionally direct. She worries about Ruger going exploring, brings him food when he is injured or hungry, and later obeys his instructions even when terrified because she believes in him 5 28 65.

Aisijin also has a fierce side. Ruger remembers her beating back kobolds who stole her prey, and she is eager to test her strength against Big Silly Hum after each improvement 12 300.

She values both strength and intelligence, regarding them as especially important virtues. Her desire to become stronger is closely tied to her wish to leave the Bedroom Space, explore the outside world, and assist Ruger rather than burden him 299 300.

Despite her straightforward nature, she becomes more conscientious and capable over time. She takes rules for the Bedroom Space’s inn seriously, participates in organizing its opening, and helps direct cultivation and cooking work alongside Big Silly Hum and the spirit furs 533 554. She also keeps track of the time Ruger spends meditating 558.

She is sensitive to causing Ruger worry. When disappointed that Big Silly Hum receives a suitable advancement potion before she does, she quickly replaces her disappointed expression with a smile upon meeting Ruger’s gaze. Ruger regards her as having an awkward but delicate soul within her imposing body 288.

Her courage does not prevent distress over unfamiliar changes. Although she dared hunt underground beasts while weak, her newly grown tail leaves her bewildered and frightened. Food quickly restores her cheerfulness, and she becomes animated while recounting her adventures with Little Regna 850 851 852.

Aisijin takes pleasure in every stage of cultivation and food production, including growing mushrooms, feeding them to edible grubs, and harvesting insect meat. Ruger believes the hunger she endured in the kobold den helps explain her deep attachment to ensuring a reliable food supply 915.

Some early fears remain despite her improved circumstances. She reacts with alarm to severe shedding even though her own fur is now healthy, because coarse fur and extensive hair loss among kobolds were associated with injury, starvation, and approaching death 954.

Her wish to become a Wizard reveals that her aspirations extend beyond physical strength. She pursues a Meditation Method in secret, then becomes dejected when she cannot master it or understand books as Nisote does 1044.

Abilities & Skills

Kobold Strength and Combat Instinct

Aisijin is physically capable even before transformation, standing out as a strong female kobold in the tribe 10.

• Could likely defeat early Ruger in a direct brawl before his magical growth 7
• Uses crude weapons such as a beast-bone knife when trying to obtain Big Silly Hum’s blood for Old Gold Tooth 10
• Defends Ruger against lizardmen with a claw blade after he creates an opening 43
• Regularly spars with Big Silly Hum after becoming a Fighter, sometimes to the point of serious wounds 192 290
• Improves her coordination with Big Silly Hum during their arena experience, adapting to a beast with three pairs of claws and a dangerous spiked tail 95
• Becomes more diligent in combat practice after learning the limits of her extraordinary healing abilities through arena fighting 102

Dragonblood Kobold Physique

Ruger transforms Aisijin with dragonblood, making her a dragonblood/dragonborn kobold 65 79.

• Greatly increases her size and intimidating presence 83
• Gives her a stronger body suitable for Fighter training 176
• Continues growing after her transformation, alongside Big Silly Hum 288
• Places her under the same broader kobold curse issues Ruger studies, though the immediate shackle does not block her early growth 299
• Her Dragonkin instincts contribute to the unusually deep sleep she experiences alongside her Dreamsleep Fighter abilities 646
• Following the appearance of her tail, Ruger confirms slightly stronger and purer dragon blood. The improvement is modest: she is only a little stronger than Big Silly Hum as a Dragonkin and remains far below Zhizhi 851 852
• The new tail’s unusual markings and its lack of resemblance to their original dragonblood source leave the nature of the transformation unresolved 851

Strength Fighter Mark

Aisijin becomes a Strength Fighter after condensing a Fighter Mark 176.

• Grants a major increase in raw strength 176
• Makes her highly compatible with Ruger’s Strength of the Savage Bull spell 290
• Supports intense physical sparring and training with Big Silly Hum 290
• Her continued strength growth eventually makes a suitable two-handed greatsword difficult to obtain, leading her to adopt a long-handled battle axe 333
• Helps her and Big Silly Hum subdue the crazed Haya without seriously harming him 333
• Grows stronger as she exercises her willpower to control the sleepiness associated with her Dreamsleep Fighter abilities 646

Nightmare / Dream Fighter Advancement

After drinking a later potion from Ruger, Aisijin undergoes a sleep-based advancement and awakens with dream-related abilities 299 300.

• Can induce drowsiness through touch or strikes 300 429
• Can enter or trigger a controllable sleep-like state in which she is asleep but remains aware 300
• Calls herself a “Dreamsleep Fighter” when offering to use her fist to help Ruger sleep 427
• Her sleeping place later appears to help other beings become “smarter,” leading Ruger to connect her special nature to dreams 396
• Her transformed Fighter Mark becomes larger than Big Silly Hum’s at the time 300
• Sleeps unusually often after her advancement, at times rivaling Zhizhi’s tendency to sleep 307 327
• Sometimes falls into deep sleep even while working. She has learned to control this through willpower, but still periodically requires long periods of sleep 646
• Her aware-but-asleep state is unsuitable for intense battle; Ruger recalls Old Lunse’s warning that maintaining it in combat would be fatal 300
• Her sleep-inducing punch does not meaningfully affect a mentally healthy Ruger, but becomes useful when he is extremely weakened 429
• Carries a very faint nightmare aura from her advancement potion, which grows somewhat stronger while she sleeps. Later fluctuations from the room she shares with Little Regna are more concentrated, but are not established as a consciously controlled ability 816 819

Castle Dreamland

Since her Dreamsleep Fighter advancement, Aisijin repeatedly returns in dreams to an inexplicably vast Castle. Ruger concludes that it exceeds an ordinary dream but does not correspond to the Nightmare World he knows 851 852.

• Initially encounters giant mushrooms that chase, bite, and ram her. Following Ruger’s instructions during her awakening, she fights and eats them, eventually becoming less afraid 300
• Appears in different parts of the Castle on successive visits and spends years wandering within it 851
• Encounters dangers including pursuing mushrooms and attacking animated armor 851
• Can influence aspects of the Castle through her will. When desperately hungry, she decides objects are edible and succeeds in eating furnishings and parts of the building, including walls and doorframes 851 852
• Receives guidance from Little Regna, whose voice she can hear even when she cannot see her. Regna helps her find routes, avoid danger, and explore with greater confidence 851 852
• Believes Regna’s guidance has brought her close to leaving the Castle 851
• Ruger suspects her faint nightmare aura and weak dragon blood together satisfied some condition within the Castle, producing her tail. This remains a hypothesis rather than a confirmed explanation 852
• Immanuel considers her transformation more likely beneficial than harmful, while leaving open possible involvement by an unknown Hybrid Dragon and unpredictable nightmare effects 852
• Later reports a dream in which she enlarges herself, strikes a winged, many-headed creature with her claws, and eats it while Ruger helps restrain it. This account does not establish that she can enlarge herself or reproduce the feat while awake 960
• Ruger still does not fully understand her condition or what Regna has led her to eat in her dreams 1015

Mental Power and Wizardry Aspirations

Aisijin’s mental power begins growing slowly after her dragonblood transformation, approaching the limits of her bloodline in a manner Ruger compares to inferior bloodline Wizard Apprentices 814.

• Increasing mental power contributes to her improved intelligence, although her underlying disposition remains simple and direct 851
• Ruger regards both her and Big Silly Hum as having some mental-power aptitude, with Aisijin particularly noteworthy 1015
• Secretly attempts to study the Meditation Method Ruger provided to Nisote, obtaining access after buying Nisote Bubble Wine with her Silver Moon Coins 1044
• Fails in that attempt and tells Ruger she cannot become a Wizard like him. No successful wizard training or wizard rank is confirmed 1044

Cooking and Food Preparation

Aisijin develops a strong interest in cooking after learning Ruger likes cooked food 6.

• Brings Ruger charred meat and cooked food in the tribe 6 28
• Personally cuts roasted meat for Ruger during Old Gold Tooth’s feast 63
• Learns cooking from Daisy and later helps develop new dishes in the Abyss Bedroom space 299 554 557
• Prepares extensive meals for Ruger after his exhausting spell transformation, including chowder, fruit tea, roasted meat, stew, and flatbreads 413
• Helps create dishes for the Bedroom Space inn, including food specially prepared for Tuzel 533 535
• Experiments with blood fingers mushrooms and other ingredients to create new dishes 554 557
• Participates in the kobolds’ simple food-scoring system using marks on skewers 459
• Continues cooking with the spirit furs nearby; one attempt to help her move a soup pot leads to a panicked cry and Stray Hair One’s dramatic account of the mishap 562
• Works with Big Silly Hum and Serious Mouse to keep Zhizhi well fed, helping Ruger encourage it to eat rather than sleep to conserve food 710
• Joins the group with their treasured soup pot to prepare their first meal in another world 952
• Earns the Beast-Eared Witch’s enthusiastic praise for both her care and her cooking. Although the chefs have no formal ranking, Tuzel reports that Aisijin has won their culinary contests slightly more often than Serious Mouse or Big Silly Hum 961

Reading and Learning

After receiving language comprehension magic, Aisijin learns to read common-tongue books 79 83.

• Reads biographical novels and adventure stories with Big Silly Hum 83 192
• Uses adventure-novel ideas when attempting to assist Ruger, including her plan to use a Dreamsleep Fighter’s fist against insomnia 427
• Asks Ruger about words she does not understand while studying cultivation notes 171
• Uses fiction as a reference point when Ruger explains Tuzel’s exaggerations 554
• Her speech and ability to organize her thoughts improve significantly after becoming dragonblooded and reading more widely 83 87 100
• Adopts the idea of reviewing shortcomings after battle from adventure stories and eagerly presents her observations to Ruger 87
• Reads stories to the spirit furs, influencing their knightly games and training 436
• Later tells stories fluently with a rich vocabulary, while the Fuzzies act out scenes from her narration; Ruger notices how far her speech has developed 753
• Despite this improvement, she remains unable to understand the books she compares herself with Nisote for studying 1044

Cultivation and Management Work

Aisijin helps maintain Ruger’s Abyss Bedroom space and its cultivation projects 171 175 554.

• Plants extraordinary seeds and buries magic stones under Ruger’s guidance 171
• Watches over seedlings and cultivation areas with Big Silly Hum 175
• Changes magic stones on the Bedroom Space platform and carries a pouch of supplies for that work 410
• Helps harvest blood fingers mushrooms and develop related dishes 554
• Assists in managing the Bedroom Space inn and strictly observes its opening rules 533
• Takes initiative with Big Silly Hum after Tuzel encourages them 554
• Keeps track of Ruger’s meditation time 558
• Helps catch fish outside the space and bring them back through its spatial gate 563
• Guards Ruger’s demon cultivation experiment with Big Silly Hum 402
• Advises keeping the Cultivation Area within the plot originally marked out by the three kobolds 554
• Keeps all the Bedroom Space’s time records. A spirit fur who regularly helps her in the Cultivation Area begins maintaining its own records after seeing hers 875
• Cultivates mushrooms as feed for edible grubs and harvests the resulting insect meat 915
• Helps grow supplementary materials for Ruger’s special spirit-fur cultivation, alongside Serious Mouse and the other caretakers 939

Affinity with Spirit Furs

Aisijin’s Dream Fighter qualities make her sleeping place especially comfortable for the spirit furs, who believe resting near her helps them become smarter 394 396.

• Allows the spirit furs to climb and train on her while she sleeps 394
• Enjoys the little furs’ company and compares them to helpful fairies from novels 410
• Assists them in daily work around the Bedroom Space and cultivation area 400 554
• Is comfortable enough with the furs’ antics that she largely ignores them climbing onto her 400
• Becomes the favored target of their pretend knightly orders during her sleepy periods, when they abandon Monster Wolf to charge the “evil sleeping dragonkin cook” 676
• Tells stories for the Fuzzies to enact and works alongside spirit furs who help maintain cultivation and time records 753 875

Equipment / Weapons / Items

• Beast-fang dagger — used to try bleeding Big Silly Hum so his healing blood can help Old Gold Tooth 13.
• Black-claw blade — uses a blade made from the severed giant black claw while helping finish off the lizardmen near the black-fruit tree 43.
• Longsword — purchased by Ruger from a blacksmith after Aisijin and Big Silly Hum begin adapting to the outside world 83.
• Long-handled battle axe — later weapon of choice after her growing strength makes an appropriate two-handed greatsword difficult to find; Ruger purchases it in Black Horn City 332 333.
• Boots — liked by Aisijin, though she removes them in the Bedroom Space to avoid damage 396.
• Cloth pouch — a pouch sewn by Daisy, used to carry small objects such as magic stones 410.
• Cooking tools / stove access — Ruger’s laboratory stove becomes a cooking tool for Aisijin and Big Silly Hum in the Abyss Bedroom space 171.
• Fighter potions — receives Fighter-related potions from Ruger, including the potion that leads to her Strength Fighter Mark and a later advancement potion 175 176 298 299.
• Stone sleeping surface and small blanket — sleeps on a reasonably flat stone in her room and prepares a blanket for Little Regna when they sleep together 816.
• Loose robe — used in an unsuccessful attempt to hide her newly appeared tail 852.
• Silver Moon Coins — money given to her by Ruger, some of which she spends on Bubble Wine for Nisote while seeking access to a Meditation Method 1044.
• Borrowed Meditation Method — secretly borrows the method Ruger gave Nisote, but fails to master it 1044.

Relationships

• Ruger — closest friend, protector, teacher, and leader figure. Aisijin shares food with him early on, trusts him through dangerous transformations, and later wants to become strong enough to help him 6 28 65 171 299. He remains attentive to her unusual sleep needs and considers obtaining a comfortable Mushroom Mattress for her 646. He investigates her altered sleep and new tail, consults Immanuel about her safety, and remains willing to help her and Big Silly Hum develop further even without the unexpected dream opportunity 816 851 852. She later confides in him about her unsuccessful secret attempt to become a Wizard 1044.
• Big Silly Hum — companion and sparring partner. They transform together, train together, cook together, and support each other’s growth 65 175 176 289 290. He also tells Ruger about her sleep-related difficulties 646. Her eventual awakening after the tail transformation makes his daily life easier 853.
• Old Gold Tooth — close elder and source of knowledge. Aisijin cares deeply for him and seeks help when he is afflicted by light strands 12 13 14. Their bond is later compared to a father–daughter relationship: he cared for her, told her stories, and gave her a name despite their impoverished tribe’s circumstances 670.
• Ka Liu / Half-Man — indirectly helps Aisijin by casting the language comprehension spell that lets her read and better understand the outside world 79 83.
• Daisy — friendly outside contact; Aisijin learns cooking from her and is encouraged by Ruger to interact with people like her. Daisy also sews Aisijin’s cloth pouch 299 410.
• Tuzel — influences Aisijin and Big Silly Hum to take more initiative in managing the Bedroom Space. Aisijin looks forward to Tuzel’s visits and helps prepare food for him, while taking his criticism of the inn’s meals seriously 533 535 554. He helps organize the food-based effort to coax her out after she grows a tail. His earlier story about a Wizard collecting dragon tails also provides context for the group’s discussion of her alarm 850 853.
• Spirit Furs — small companions and helpers in the Bedroom Space. They are drawn to Aisijin’s sleeping place and often climb on her, while she finds them lively and charming 394 396 410. Her stories influence their games, and they act out scenes from her narration 436 676 753.
• Serious Mouse — collaborator in cooking and cultivation. Serious Mouse helps cultivate ingredients for Aisijin’s dishes and joins her, Big Silly Hum, and Tuzel in judging new recipes 554 557. Serious Mouse later provides her with a proper place to sleep at the inn 646. It also helps fan the food aromas toward her room when the companions try to coax her out after her transformation 850.
• Shazhang — formerly helped Aisijin when her sleepiness overtook her, taking her to rest among the rocks 646.
• Little Regna — close companion, dream guide, and guardian. Regna deliberately sleeps alongside Aisijin, often in her arms, after sensing that she needs help. She can enter Aisijin’s dreams and guide her by voice, transforming the frightening Castle into a place they can explore together. Aisijin credits her with helping her navigate its vast interior 695 813 816 851 852.
• Monster Wolf — guards the door of the room where Aisijin and Little Regna sleep; it can also obey Regna 819.
• Immanuel — Ruger’s teacher, consulted about Aisijin’s unexplained tail. He judges the change more likely beneficial than harmful, without claiming certainty about its origin 852.
• Zhizhi — fellow companion whose feeding and growth she helps support alongside Ruger, Big Silly Hum, and Serious Mouse 710.
• Nisote — recipient of Bubble Wine Aisijin buys with Ruger’s gift money. She secretly borrows the Meditation Method Ruger gave Nisote while attempting to become a Wizard 1044.
• Beast-Eared Witch / Miss Hair-Shedding — a guest Aisijin looks after. The witch wishes to thank her personally and calls her cooking the best in the world, but Aisijin is asleep when she departs, so Ruger offers to relay the message 961.

Story Role / Major Arcs

Early Tribe Arc

Aisijin serves as Ruger’s first meaningful bond among the kobolds. She brings news of changing masters, shares food, warns him about lizardmen, and helps him stay connected to the tribe despite his isolation 2 5 6.

Old Gold Tooth and Dragonblood Arc

Aisijin leads Ruger to the injured Old Gold Tooth and helps use Big Silly Hum’s blood to prolong him. Her concern for Old Gold Tooth pushes Ruger deeper into kobold history, dragonblood transformations, and the curse affecting their race 12 13 14.

Their relationship is later clarified as an exceptional bond resembling that of a father and daughter. Old Gold Tooth’s care, stories, and naming of Aisijin distinguish her early life from that of most kobolds in their poor tribe 670.

Leaving the Tribe

After Ruger obtains access to dragonblood and the Abyss Bedroom space, Aisijin and Big Silly Hum are transformed into dragonblood kobolds and eventually leave the tribe’s narrow world behind. Aisijin is excited by the outside world but misses Old Gold Tooth 65 79.

Their early adjustment includes learning to handle purchased weapons, discussing their combat shortcomings, and fighting an arena beast as a coordinated pair. The arena experience makes them more diligent in training and more aware of their healing abilities 83 87 95 102.

Abyss Bedroom Growth

Aisijin becomes one of the main caretakers of Ruger’s Bedroom Space. She reads, cooks, plants, harvests, trains, and slowly shifts from protected companion to active helper 171 175 192 554.

As the space expands, she also becomes a nurturing presence for the spirit furs and an organizer for the group’s shared living area. She helps maintain the cultivation plot, prepare the inn, and develop its food offerings 394 410 533 554. She later helps catch fish to provision the space, while the inn provides a place for the extended rests her abilities require 563 646.

Her responsibilities continue to expand into keeping the space’s time records, cultivating feed and edible insects, and supplying materials for Ruger’s specialized spirit-fur research. Her storytelling also contributes to the spirit furs’ shared culture and play 753 875 915 939.

Fighter Development

Ruger guides Aisijin into the Fighter path. She first becomes a Strength Fighter, then undergoes a special sleep-based advancement that awakens dream and drowsiness-related abilities 176 299 300 396.

Her later use of these powers is primarily supportive: she wants to use her Dreamsleep Fighter ability to give Ruger rest when he is exhausted or unable to sleep 427 429. The advancement also makes her prone to deep sleep, sometimes during work. Resisting it through willpower strengthens her Fighter Mark, though she still needs occasional long rests 646.

Exploration and Combat Support

Aisijin increasingly accompanies Ruger and Big Silly Hum beyond the Bedroom Space. She eagerly explores new environments, participates in hunting trips, and provides direct combat support when danger arises 333 334 424.

She later joins the companions’ first meal in another world, bringing their soup pot and continuing her supportive role through food preparation 952.

Dream Castle and Tail Transformation

Little Regna’s habit of sleeping with Aisijin develops into a deeper connection: she is entering Aisijin’s recurring Castle Dreamland to guide and protect her. Ruger first investigates changes in Aisijin’s deep sleep and intermittent nightmare fluctuations without understanding their significance 813 816 819 851 852.

Aisijin’s awakening with a tail prompts both concern and a comic communal effort to lure her from her room with food. During the following feast, she explains that the Castle has been present since her Fighter advancement and that Regna’s guidance has helped her escape aimless wandering 850 851.

Ruger finds that the Castle is neither an ordinary dream nor the familiar Nightmare World, and that Aisijin’s will can affect its contents. The tail brings only modest measurable dragonblood improvement, despite its striking appearance. Immanuel’s cautiously favorable assessment allows the group to celebrate, but the Castle’s origin and the precise nature of Aisijin’s development remain unexplained 851 852 853.

Her later account of becoming enormous to eat a many-headed creature, and Ruger’s admission that he cannot fully understand her condition, indicate that her dream experiences continue to develop beyond his current knowledge 960 1015.

Aspirations Toward Wizardry

Aisijin’s desire for intelligence and strength eventually leads her to try learning a Wizard’s Meditation Method independently. She obtains access through Nisote but fails to master it. Her disappointed confession to Ruger exposes both her continuing ambition and the gap between her unusual mental-power development and successful wizard cultivation 1044.
