Background

Li Yu’s story began not in the world he came to inhabit, but in a parallel universe where the resurgence of spiritual energy had opened the door to demons, interdimensional creatures, and extraterrestrial threats. The original Li Yu—the version of himself native to this world—was a high school student on the verge of class placement, suffering from severe depression that had long since eroded his will to live. When he awakened his unique talent, he discovered it was a one-time-use ability: the power to summon a version of himself from another world to take his place. The realization that his entire existence could be negated by his own gift was the final blow. “It was as if he were nothing more than a sacrifice; the appearance of such a talent completely negated his entire existence” 1. Without hesitation, he activated the ability, pulling Li Yu from a parallel reality into his own. In that instant, the two merged—the original Li Yu found release, and the new Li Yu inherited his identity, his memories, and his life 1.

The merging was sudden and complete. Li Yu recalled the moment clearly: “a guy who looked exactly like him summoned him out, and before he could even be surprised, the man merged directly with him… bestowing all his memories and identity upon him” 1. The original Li Yu’s memories were a burden and a guide. They revealed a world in turmoil—spiritual energy had resurged, bringing monsters and rifts—but also a lonely existence marked by poverty and isolation. The original was an orphan with few friends and almost no social circle, which made the transition easier. “You might be fine now, but I’m the one who’s screwed. It’s a good thing you were a loner with no friends, or this would be a real headache,” Li Yu grumbled as he examined the ID card that gave him a legal identity 1. He had little choice but to accept the situation. The original Li Yu had already given up; the new Li Yu resolved to live well in his place.

Li Yu’s own talent, the Eye of Keigeko, awakened during or shortly after the merging. This ability—described as “the ultimate eye capable of seeing through all phenomena; learn it at a glance, master it at a second look”—allowed him to rapidly absorb knowledge and skills 1. Combined with the inherited memories, he was able to quickly orient himself in the new world. He assessed his power level according to the world’s standards, placing himself at Tier 2, and began cultivating true energy and magic 2. The world itself was undergoing integration with parallel dimensions; Li Yu learned that dimensional rifts could lead to entire worlds like Orario, and that the process of world integration was already underway 29. This knowledge shaped his understanding of the dangers and opportunities ahead.

Despite the abruptness of his arrival, Li Yu showed remarkable adaptability. He decided to display a portion of his talent to secure school resources without exposing the full extent of his abilities 2. He began studying martial arts from elderly practitioners in the park, his talent instantly surfacing the patterns of their techniques 1. He set out to master sword techniques, aiming to become the “Ultimate Sword Soul” of this world, and used his phone to learn various styles overnight 16. The original Li Yu’s depression and despair were replaced by a determined pragmatism. “The other me really had it rough!” Li Yu sighed, but he did not dwell on the tragedy 1. He focused instead on making money, improving his skills, and building a new life. The merging of memories was not a catastrophic psychic break but a seamless integration that gave Li Yu the foundation he needed to survive in a world that had become both wondrous and dangerous.

Personality

• Calm and composed: When his homeroom teacher advises him not to be arrogant about his talent, Li Yu nods calmly, and the teacher notes that he "had a steady mindset" and likely wouldn't fall into arrogance 5.
• Confident in his abilities: After learning sword techniques, Li Yu tells Yukino Yukinoshita, "I’ve learned what I needed, and I feel like I can come up with an even stronger sword technique" 17.
• Strategic and pragmatic: Li Yu decides to display only part of his talent to the school, reasoning, “If you play the pig for too long, you really become a pig,” and that by competing he can secure more resources 2.
• Dedicated and hardworking: On the day he breaks through to the fourth rank, Li Yu practices martial arts “the rest of the day, aside from meal times,” staying immersed until he succeeds 44.
• Ruthless but respectful in competition: During his spar with Yukino, Li Yu activates the Eye of Keigeko to learn all her techniques, admitting he went all out because he believes “showing respect to his opponents by not holding back” 12.
• Arrogant and laid-back at times: When Asuna Yuuki introduces herself, Li Yu simply nods and continues playing on his phone, showing little immediate interest 17. Later, Yukino internally labels his remarks as “'Versailles-style' humble-bragging” 17.
• Humble despite exceptional talent: The homeroom teacher observes that Li Yu “had a steady mindset and likely wouldn’t fall into the trap of arrogance,” and he accepts her advice without protest 5.
• Playful and joking: Li Yu teases Kato Megumi about giving her a massage after she mentions being tired, though he understands boundaries and stops when she declines 14.
• Kind and supportive toward classmates: After Kato Megumi exhausts herself during training, Li Yu uses qi to help her recover 13. He also offers her advice on controlling her newly broken-through talent 24.
• Curious and experimental: After his talent grows stronger at the fourth rank, Li Yu successfully creates strawberry-flavored Red Potion and blueberry-flavored Blue Potion on his first attempt, driven by curiosity 44.
• Determined and competitive: Li Yu challenges Yukino to a spar, observing that he wants to “see it himself” and test her talent, and later presses her for a rematch to try his new moves 10 17.
• Understanding of social norms: Though he jokes, Li Yu respects Kato’s refusal of a massage, showing he knows when to stop 14. He also declines Sister Mi’s offer of a free weapon at first to avoid owing favors, though he later accepts under her insistence 14 15.
• Self-sufficient and pragmatic about money: Realizing he has only about 5,000 left, Li Yu plans to be frugal and shops for a cheap weapon, highlighting his awareness of financial limits 14.

Abilities

Eye of Keigeko (Learning Magic Eye)

The Eye of Keigeko is Li Yu’s primary and most formidable ability, a learning-type talent he describes publicly as a “Learning Magic Eye” to conceal its full power. At its core, the Eye allows him to absorb, synthesize, and master any information or technique he observes—whether from books, videos, or live demonstrations—with extraordinary speed and precision. When activated intentionally, the Eye goes further: it enables Li Yu to analyze an opponent’s every movement and energy flow, granting him the ability to foresee their actions and learn their techniques in real time. This makes him a terrifyingly adaptive combatant, capable of turning an enemy’s strengths against them. The Eye also works passively, subconsciously processing information such as magic arrays or complex diagrams simply by seeing them. Li Yu’s talent grows stronger as his own power increases, allowing him not only to learn but to surpass existing knowledge and innovate new applications, such as creating flavored potions or improving combat techniques.

• Applications:

  • Rapidly reads and comprehends entire books on magic, martial arts, and monster compendiums within minutes 2 4.
  • Learns martial arts techniques from short videos, grasping even untaught force-generation methods 4.
  • Masters sword techniques, including the “Ultimate Ghost Sword Technique” from his past life’s game, by watching tutorials online 16.
  • Copies Yukino Yukinoshita’s techniques and her innate bodily-control talent mid-spar after activating the Eye 12.
  • Foresees an opponent’s every move during active combat, making attacks easy to deflect 12.
  • Learns complex field magic arrays and spells (e.g., storage magic, wind and water magic) after a single explanation or observation 24 26 34 48.
  • Synthesizes potion-making knowledge to create strawberry-flavored Red Potion and blueberry-flavored Blue Potion on the first attempt after a breakthrough 44.
  • Understands meditation and senses mana instantly upon reading a guide 2.
  • Subconsciously activates when encountering a magic circle, absorbing its structure without conscious effort 19.

• Limitations:

  • Li Yu deliberately hides the full extent of the Eye, initially describing it only as a “learning talent” to secure school resources without arousing suspicion 2 3.
  • Passive learning is slower and less comprehensive; active activation requires mental focus 12.
  • The Eye appears selective when copying talents from others—it only works when the target’s talent is fully demonstrated in action (e.g., Kato Megumi’s passive learning or Yukino’s bodily control), and it rejects talents that are not actively displayed 21.
  • Copying a talent does not always succeed; Li Yu observed fighters at a street scene and could not copy their talents, finding the process “picky” 21.
  • The Eye’s growth is tied to Li Yu’s own power; breakthroughs in magic or martial arts unlock deeper capabilities, meaning it is not static 43.

Magical Talent

Li Yu possesses an exceptionally high affinity for magic, allowing him to sense and accumulate mana far faster than average. During his first attempt at meditation, he felt mana seeping into his body immediately, whereas books state that those with good aptitude need a week to sense it. This rapid mana absorption fuels his quick progression through magical tiers—he reaches the Fourth Tier in mana within weeks of awakening. His magical power is described as “immense,” enabling him to cast spells with ease. However, his early progress was tempered by limited mana reserves, which restricted the number of spells he could initially cast. As Li Yu’s talent grows with his strength, his magical prowess also enhances, allowing him to project mana externally at Tier 4 and contemplate intermediate magic.

• Applications:

  • Senses mana on the very first try at meditation, defying typical learning curves 2.
  • Accumulates enough mana to break through to Tier 2 quickly and later to Tier 4 2 43.
  • Masters basic wind and water magic easily after being taught by Teacher Li 34.
  • Can project magic externally after reaching Tier 4, forming mana on his fist 43.
  • Learns and casts multiple spells on a bus ride (including an item-storage spell) under Teacher Li’s instruction 48.
  • Draws and activates complex magic arrays for customers, demonstrating advanced control 24.

• Limitations:

  • Initially, Li Yu’s mana reserves are small, preventing him from casting many spells 8.
  • Teacher Li refuses to teach intermediate magic until Li Yu reaches the Fourth Tier, warning of the dangers of premature attempts 34.
  • Magic progression is tied to overall tier; breakthroughs in magic and martial arts often coincide 43 44.

Learning-Type Talent (General)

Li Yu’s publicly acknowledged ability is a general learning-type talent that lets him understand and master information after a single exposure. This is the sanitized version of his Eye of Keigeko, presented to the school to explain his rapid improvements. It is incredibly versatile, applying to both martial arts and magic, and allows him to learn from any medium—books, videos, or direct observation. This talent is what initially astounds his homeroom teacher and leads to his placement in a special class. He uses it to rapidly improve his combat skills, learning multiple martial arts and weapon techniques in a single day.

• Applications:

  • Learns to condense true qi and heal minor injuries after a single demonstration by teacher Shizuka Hiratsuka 9 10.
  • Masters various weapon styles (sword, dagger, Tang dao) from online videos 8 16.
  • Grasps complex techniques like force-generation that even the video’s author didn’t teach, by synthesizing information 4.
  • Understands the theory of meditation and true qi from books without needing repeated study 2.
  • Becomes the strongest student in hand-to-hand combat in his class within a short time 8.

• Limitations:

  • Requires a source of information (visual or textual); cannot learn from abstract concepts without prior knowledge.
  • The talent’s full potential is hidden; Li Yu records only “seems to be Learning Magic Eye” on his form, leaving specifics vague 3.
  • Learning speed is still limited by time—he needs to watch videos or read pages, though extremely fast 4.

Talent Growth and Innovation

A unique property of Li Yu’s abilities is that they grow stronger as his own power increases. After breaking through to the Fourth Tier in both magic and martial arts, he discovers that his talent has also evolved—he can now surpass the knowledge he has already learned and create entirely new formulas or techniques. This is demonstrated when he modifies Basic Potion recipes to create flavored versions on his first try, a feat that would have failed before the breakthrough. This growth is compared to Kato Megumi’s talent, which also intensified after her breakthrough and began affecting others. For Li Yu, the effect is self-directed, allowing him to generate better insights and innovations spontaneously.

• Applications:

  • Creates strawberry-flavored Red Potion and blueberry-flavored Blue Potion on the first attempt after his mana tier breakthrough 44.
  • Gains improved understanding of existing techniques and formulas upon waking after breaking through 43.
  • Feels “strange ideas” pop into his mind, leading to better spell and potion concepts 43.
  • After martial arts breakthrough, he can project internal energy and perform the Ghost Sword Technique he had theorized 44.
  • Now capable of crafting Intermediate Potions, which were previously out of reach 44.

• Limitations:

  • The growth is passive and only manifests after a major breakthrough in power (magic or martial arts tier) 43.
  • The mechanism is not fully understood by Li Yu himself; he speculates it may be a gradual “unsealing” of his Eye of Keigeko 43.
  • Innovation requires prior knowledge; he cannot create completely out of nothing (e.g., he modifies existing potion recipes, not invents new categories yet).

Copying Talents (via Eye of Keigeko)

When Li Yu actively uses his Eye of Keigeko in combat or intense observation, he can copy not only techniques but also the innate talents of others, integrating them into his own arsenal. This ability was revealed during his spar with Yukino Yukinoshita, where he not only learned her fighting moves but also replicated her talent for perfect bodily control—the ability to command every ounce of power within one’s body. This granted him a significant boost in combat precision and energy efficiency. The copying process appears to be selective, possibly requiring the target to fully demonstrate their talent in a high-pressure situation.

• Applications:

  • Copied Yukino Yukinoshita’s bodily-control talent, enabling flawless control of internal energy and physical strength 12.
  • Used the copied talent immediately to counter Yukino’s attacks and improve his own techniques 12.
  • Potentially other talents could be copied if observed under the right conditions 12.

• Limitations:

  • The Eye is “picky”; it did not copy talents from bystanders fighting at a street scene, likely because their talents were not fully displayed 21.
  • Only works when the Eye is actively activated with intent to learn 12.
  • Copied talents may not be permanent? (Not specified, but Li Yu retains Yukino’s talent after the fight) 12.
  • Requires direct observation of the target demonstrating their ability in a manner that reveals its essence.

Equipment

Equipment in this world is essential for survival, combat efficiency, and economic self-sufficiency. From weapons to potions and storage solutions, each piece of gear serves a specific purpose and reflects the user’s resources, skill, and strategic preparation. The following items are detailed based on their acquisition, function, and significance to the characters, particularly Li Yu.

• Tang Dao (Sword/Blade)
  Li Yu’s primary weapon is a Tang dao, a straight-bladed blade approximately three feet long with a silvery-white blade that radiates a cold light and a hilt wrapped in an unknown material 15. He acquired it from Sister Mi’s shop, Jimmy Weapons, after she insisted on giving it to him despite his inability to pay. The blade is of exceptional quality, bone-chillingly cold to the touch and far beyond ordinary steel 16. Sister Mi also provided a scabbard and a blade cover for training safety 15. The Tang dao allows Li Yu to practice the blade and sword techniques he learns from online videos, including the Ultimate Ghost Sword Technique he intends to master 16. Its quality is noted by classmates such as Kato Megumi, who immediately recognizes its superiority and seeks to buy weapons from the same shop 30. The significance lies in its role as a reliable, high-grade tool for martial arts development; with it, Li Yu can channel internal energy and project energy outward after his breakthrough to the fourth rank, making close-quarters combat far more effective 44. The blade also serves as a medium for the Magic Array storage spell later taught by Teacher Li 48.

• Spatial Bag (Asuna’s)
  Asuna carries a Spatial Bag that cost tens of millions, a high-end storage item that allows her to carry far more than an ordinary backpack. She packs kitchenware, ingredients, and other supplies for the Dungeon expedition with ease 44. Its significance is practical: while Li Yu must be frugal and pack minimally, Asuna’s Spatial Bag enables extensive preparation, symbolizing the wealth and convenience available to those who can afford it. It also highlights the economic disparity between characters and the importance of money in this world 16 44.

• Red Potion and Blue Potion (Flavored Variants)
  Li Yu creates standard Red and Blue Potions—recovery items that restore health and mana—but innovates by adding special flavors without increasing cost. He successfully brews strawberry-flavored Red Potion and blueberry-flavored Blue Potion on his first attempt after breaking through to the fourth rank 44. The potions retain full efficacy and are praised for their pleasant taste, making them more appealing to peers like Asuna, Kato Megumi, and Yukino Yukinoshita 45 46. These potions are sold in sealed medicine bags; Li Yu sells them at a profit (earning 36,000 yuan from orders of 30 bags each of Red and Blue Potions), establishing a reliable income stream 42. The flavored potions also demonstrate Li Yu’s advanced alchemical talent—he can innovate beyond basic recipes 44. For the Dungeon, such potions are essential for sustained adventuring, and Li Yu’s ability to produce them cheaply makes him a valuable supplier to his class 46.

• Potion-Making Equipment and Tools
  To concoct potions, Li Yu purchases specialized equipment from Treasure Tree Hall, a reputable herb shop. The tools include a kettle-like device used for extracting medicinal essences, which requires an infusion of mana to operate 40. He also buys medicine bags (modern pouches for packaging liquid potions, more convenient than traditional glass bottles) 40. The materials (herbs such as Inula Flower, Violet Pill, Evening Primrose) are weighed and sealed in airtight bags; Li Yu verifies their quality and accurate weight 40. This equipment is foundational for his alchemy practice, allowing him to mass-produce potions for personal use and sale, turning a profit and gaining self-reliance 41 42.

• Magic Array for Weapon Storage
  Teacher Li teaches Li Yu a spell to store his weapon using a Magic Array. Li Yu applies a mark to his Tang dao, channels mana, and the weapon is pulled into the array, allowing him to summon it at will 48. This spell is not a true spatial storage (which would obsolete expensive spatial equipment) but is highly useful in combat—for instance, suddenly summoning a weapon during close-quarters fighting to surprise an opponent 48. Li Yu also considers extending the spell to create a medium-based storage system, effectively carrying a warehouse 48. The significance is tactical convenience: he no longer has to carry the Tang dao visibly and can draw it instantly, enhancing his versatility and surprise capability. It also demonstrates his quick mastery of new magic.

• Weapons Shop (Jimmy Weapons) and Other Arms
  Sister Mi’s shop, Jimmy Weapons, is the primary source for the class’s arms. The shop displays cheap weapons on the ground floor but keeps high-quality custom-made pieces upstairs, crafted by Sister Mi’s husband whose talent is entirely focused on smithing 30 35. Li Yu brings his classmates there before the Dungeon event, and they purchase weapons suitable to their styles: Kato Megumi obtains a dagger, Yukino Yukinoshita a short sword, and others also buy based on Li Yu’s recommendations and discounts 35. The significance of this shop is twofold: it provides reliable, high-quality weapons essential for dungeon survival, and it acts as a hub for business relationships (Li Yu promises to sell monster materials to Sister Mi in repayment for the Tang dao) 15 35. Additionally, Asuna owns a rapier, which she uses with her talent for increased attack speed and precision 32 44.

• Scabbard and Blade Cover
  Sister Mi gives Li Yu a scabbard and a blade cover alongside the Tang dao 15. The blade cover is used to prevent accidental injuries during training. While seemingly minor, these accessories are essential for safe handling and storage, reflecting Sister Mi’s care and the practical demands of daily weapon use.

• Power Bank and Essentials
  For the Dungeon trip, Li Yu packs a change of clothes and a power bank 44. These mundane items underscore the need for basic comforts and electronic devices even in a magical world, especially since Li Yu relies on his phone for learning techniques from videos 16. The power bank ensures he can continue studying during rest periods.

Relationships

• Asuna Yuuki: Asuna is a wealthy new transfer student who sits behind Li Yu in class and quickly becomes one of his closest companions. She initially introduces herself with a request to be taken care of, but Li Yu seems uninterested at first 17. Their relationship deepens through shared combat and daily life: they fight Goblins and a Minotaur together 30, engage in a sword duel where Li Yu copies her techniques—causing Asuna to doubt her own talent 32, and regularly cook and eat meals together, with Li Yu offering to make potato stewed beef brisket for her 27 38. Asuna also trusts Li Yu’s abilities, buying a spatial backpack and asking him to set up a Magic Array at her home 25 37. She eventually teams up with Li Yu for practical classes 49.

• Kato Megumi: Kato is Li Yu’s desk-mate with an exceptionally faint presence that makes others overlook her, but Li Yu notices and greets her on the first day, leading her to the cafeteria 7. She becomes a regular part of his group, often working with him on practical matters: she gives Li Yu a list of materials for Asuna’s Magic Array 25, asks for his recommendation on weapon shops 30, and has him set up a Magic Array at her home 38. Kato also benefits from Li Yu’s help in training—he uses qi to help her recover from exhaustion after a sparring session 13—and she shows gratitude for his work 38. She teams up with Li Yu, Asuna, and Yukino for group exercises 49.

• Yukino Yukinoshita: Yukino is a wealthy, composed classmate who initially challenges Li Yu to a spar, which he wins by copying her talent and techniques using the Eye of Keigeko, leading to mutual respect—though Yukino becomes reluctant to spar again due to his overwhelming strength 10 12 13 18. She frequently interacts with Li Yu in the context of training and team formation, often expressing unwillingness to team with him because he is too strong 14 17. Despite this, she becomes part of his circle: she asks him to set up a Magic Array at her home 24 25 37, visits weapon shops together with the group 35 37, and eventually agrees to team with Li Yu for practical class 49. She also reveals a softer side by showing Li Yu and the others her two fighting kittens 37.

• Shizuka Hiratsuka: Shizuka is the homeroom teacher who trains the class in martial arts and qi control. She witnesses Li Yu’s spar with Yukino and is taken aback by his ruthless yet respectful fighting style 12. She personally guides Kato Megumi in training and continues to push all students to break through ranks 13 34. Li Yu interacts with her as a student, learning techniques like using qi to heal minor injuries 10, and she supports his aggressive training methods for male classmates 34.

• Sister Mi: Sister Mi is the owner of a weapon shop who shows generosity toward Li Yu. She initially offers him a free weapon, which he declines to avoid owing favors 14. Later, she gifts him a Tang dao sword 16. Li Yu brings Asuna, Kato, and Yukino to her shop for weapon purchases, and she treats them as valued customers 35. She also sells Asuna a spatial backpack for 30 million and jokes with the group as they leave 37.

• Teacher Li: A teacher who instructs the class on magic. Li Yu quickly masters wind and water magic, surprising Teacher Li with his immense mana, but Teacher Li refuses to teach him intermediate magic until he reaches the fourth rank, warning of the risks 34.

• Xia Yu: A female classmate who spars with Yukino Yukinoshita during training. Yukino helps Xia Yu achieve a breakthrough, and Xia Yu later jokes with another student about Yukino possibly taking Li Yu’s advice to heart and slapping her hard 34.
