Sasamori Aya

Biodata

Power Progression

Background / History

Before meeting Haimo, Aya defeated the Five Heavenly Swords individually and established herself as Kyōsei Academy’s “Empress.” Years of intensive Uechi-ryu training had transformed her body into a weapon, but the absence of worthy opponents left her profoundly bored 3 4.

Haimo’s arrival gave her an opponent she could not overpower. When he countered her attack and injured her hand, she welcomed the unfamiliar pain rather than retreating. She knelt and asked him to take her somewhere she could “truly live,” accepting his promise that she could eventually become strong enough to astonish the gods 5 6.

Aya accompanied Haimo and the other recruits through a gate to Orario, arriving in his dilapidated temple. She subsequently received his Falna and began exploring the Dungeon. When later given an opportunity to revisit her original world, she chose to remain with him instead 16 23 35 171.

Appearance

• Build: Tall and athletic, with firm, sleek musculature developed through years of martial training 4 23.
• Hair: Long, straight, ink-black hair 23.
• Eyes: Black, narrow, and sharply upturned; described as phoenix-shaped 126 265.
• Skin: Pale or ivory-white, contrasting with the toughness of her trained body 23.
• Typical clothing: Fitted black light armor in the Dungeon; frequently wears an oversized white shirt around the mansion 30 290 305.

Personality

Aya judges people primarily by strength. At the academy, she dismissed opponents she had already defeated and showed little respect for authority. Her submission to Haimo follows his demonstration of overwhelming power, not his divine title alone 5 6.

Combat provides her with a sense of existence that ordinary life cannot. She openly relishes pain, danger, and unrestricted battles to the death, and often considers Dungeon monsters too weak to satisfy her. This fixation makes her reckless: she deliberately attracts monster swarms, neglects her companions’ limitations, and pushes herself beyond exhaustion for even a single additional Status point 55 92 107 129.

Her competitiveness does not prevent her from acknowledging defeat. After losing to Ryu Lion, she rejects hypothetical excuses and immediately resolves to challenge her again. Outside combat, she is solitary and indifferent to comforts such as securing a desirable bedroom 76 86.

Aya is openly possessive toward Haimo, but also reveals insecurity about the distance between them. She confesses that becoming stronger deepens her emptiness because she still believes she can never defeat him. Her reverence for strength also produces harsh judgments of others: she treats Lili’s helplessness with contempt, provoking Rin’s rejection of her worldview 186 187 352.

Abilities & Skills

Uechi-ryu

An ancient Ryukyu martial art focused on conditioning the body to its limits and turning every part of it into a weapon 3 5.

• Uses knife-hands, spear-hands, elbows, knees, kicks, and grappling 5 85 128.
• Favors relentless close-range pressure, sometimes abandoning defense entirely 85.
• Can assess another fighter’s experience through combat instincts and force application; recognizes that Ryu’s technique was developed in lethal battles 346.

Incarnate Blade

A Falna skill that treats Aya’s flesh as a weapon and allows its physical properties to exceed normal human limitations 130.

• Scaling toughness: Her body’s physical strength increases greatly with Strength and Endurance 130.
• Damage negation and recoil: Physical attacks trigger a comparison of the combatants’ Strength and Endurance. A favorable result can negate some damage and return the received impact severalfold as Shock Force 130.
• Armor-piercing attacks: Unarmed strikes count as slashes from a fine blade of the same level and possess Armor-Piercing 130.
• Demonstrated applications: Blocks a Goblin’s sword without broken skin, pierces a Goblin’s torso bare-handed, and tears apart a Killer Ant’s armored body 35 36 39.
• Limit: Does not eliminate level disparities or exhaustion. Ryu defeats her while Aya is Lv.1, and prolonged battles can still injure and drain her 86 385.

Battle Frenzy

Converts Aya’s obsession with strength into accelerated growth 84 130.

• Greatly increases gains in all Status attributes and proficiency 84.
• Its growth multiplier has no stated upper limit and depends on the depth of her obsession 84.
• Doubles Status growth when she fights someone she regards as a target that must be surpassed 84.
• Recognizes struggle subjectively rather than requiring conventional armed combat. Haimo identifies her determination to overcome him during intimacy as a valid trigger 189 190.
• Can encourage dangerous overexertion: Aya continues demanding combat and Status updates even when barely conscious 128 129.

Rigid Body

A development ability obtained at Lv.2 that greatly enhances bodily hardness and resistance to blows, giving her flesh steel-like toughness 130.

• Haimo attributes its emergence to her determination to endure punishment so she can continue fighting 131.
• Aya values it as a means of landing one more attack before being killed, rather than as a purely defensive ability 131.

Killing Intent

Aya can project an oppressive murderous presence strong enough to silence experienced adventurers. On the eighteenth floor, her threat and killing intent immediately stop nearby gossip about the Familia 328.

• During the later Monster Party, her fully activated Battle Frenzy accompanies a faint, nearly tangible red killing aura 385.

Massage and Recovery Techniques

Aya learned to massage herself while training and fighting alone. She considers removing muscular fatigue essential to maintaining the next day’s training performance 290 291.

• Applies these techniques to Haimo’s temples, scalp, and pressure points; he praises her skill 290.

Equipment / Weapons / Items

• Shadow Leopard light armor — Black protective gear incorporating leather, metal plates, and refined steel wire. Protects vital areas while preserving joint mobility; Tsubaki describes it as lightweight and wear-resistant 30.
• Fire-resistant protection in practice — Her armor remains undamaged after a Hellhound’s flames engulf her, although her hair curls slightly 92.
• No regular handheld weapon — Primarily fights with her own body. She is nevertheless willing to seize a monster’s weapon if it lets her continue fighting 85 106.

Relationships

• Haimo — Patron god, ultimate combat goal, and intimate partner. His strength gives her a new purpose, while he manages her growth and insists on recovery when she overexerts herself. She later declares an ambition to follow his footsteps and someday “devour God” 5 84 186 190 291.
• Onigawara Rin — Former academy opponent and fellow Familia member. Frequently clashes with Aya over swordsmanship, recklessness, monopolizing Haimo, and the treatment of weaker people. Rin nevertheless envies Aya’s pure desire for battle 6 105 265 306 352.
• Ryu Lion / Ryuu — Sparring rival selected by Haimo as a more attainable opponent. Defeats Aya in their first documented match; both accept the prospect of further challenges 84 85 86 184.
• Tsubaki — Equipment adviser and Dungeon guide. Respects Aya’s potential but restrains her recklessness, successfully stopping a deeper solo descent by invoking Haimo’s concern 30 74 107.
• Kikakujō Mary — Fellow recruit and adventuring companion. Helps fight the Killer Ant swarm Aya attracts and later competes with her for time beside Haimo 92 305 306.
• Tsukuyo Inaba — Fellow recruit and combat companion. Aya protects her from a hidden attacker during Lili’s rescue 16 352.
• Lili — Participates in her rescue but disparages her weakness and later questions her usefulness to the Familia 352 355.
• Kisara Tendo and Kohina Hiruko — Prospective opponents whose abilities excite Aya’s interest; she directly requests a future match with Kisara 297 331.

Story Role / Major Arcs

First Dungeon Expeditions

Aya immediately distinguishes herself by charging monsters bare-handed and relying on her hardened body to withstand their weapons. Her appetite for danger escalates into covering herself in Killer Ant pheromones, drawing a swarm that the party fights for two hours. Haimo also learns that she slaughtered Al-Miraj on the thirteenth floor to provoke a Monster Party 35 36 39 92 127.

Her desire to descend further eventually conflicts with the party’s damaged equipment and fatigue. Tsubaki prevents her from continuing alone by reminding her that Haimo would worry 106 107.

Rivalry and Limit Training

Haimo arranges a match with Ryu to give Aya a visible intermediate goal rather than leaving her fixated solely on an unreachable god. Her defeat strengthens her determination rather than discouraging her 84 86.

After reaching SS attributes, Aya attacks Haimo to force further growth. A night of repeated defeats and Status updates ends with four SSS1299 attributes and her subsequent advancement to Lv.2 127 128 129 130.

Reputation in Orario

Aya’s Dungeon exploits earn her the unofficial name “Monster Wearing Human Skin.” She later returns carrying several Minotaur horns amid rumors that she killed a group of Minotaurs alone. Her threats also contribute to the fear surrounding the Familia, including among adventurers encountered near Rivira 264 265 328.

Lili’s Rescue

During Rin and Inaba’s intervention against Soma Familia members, Aya kicks a hidden attacker away from Inaba. Her subsequent contempt for Lili’s inability to defend herself creates a direct ideological clash with Rin, who cites Haimo’s teaching that strength should not become an excuse to ignore injustice 352.

War Game Proposal and Monster Party

As the Familia’s growing strength makes familiar Dungeon floors less challenging, Aya proposes challenging another Familia to a War Game. Rin objects that their registered levels and numbers are insufficient; Aya counters with her estimated B-rank attributes and confidence in the newcomers’ combat abilities 376.

In a later expedition, Aya kills a Mammoth shortly before the Dungeon releases a multiplying horde. She fights alongside the others, but accumulating injuries and dwindling stamina force them into a defensive circle. Seitenshi then casts Ideal Utopia to enhance the Familia 385.
