Background / History

Kyosuke is a modern-Earth transmigrant who awakens in the body of an Uchiha child. He discovers a system interface offering character data, quests, Instance Dungeons, experience points, and upgradeable skills. Determined to improve his position in the clan, he defeats his bullying cousin Hiroji and publicly carries him to the Council Hall, drawing the clan’s attention 2.

Aware of Uchiha political tensions, Kyosuke deliberately cultivates an image of loyalty toward the clan elders rather than the clan head or village. His intervention helps draw senior clan members’ attention to Fugaku Uchiha, who subsequently gains support as a leadership candidate 5 20.

He briefly serves in the Military Police Force, but repeated patrols undertaken to earn experience points lead to his removal. Kyosuke then focuses on research under Orochimaru, mastering anatomy, human modification, cloning, and cell transplantation while gaining access to Orochimaru’s laboratory and instruction 18 19 30.

Kyosuke later joins Anbu under the codename Serpent. He becomes entangled among the Uchiha Clan, Root, Orochimaru, and the Hokage’s Anbu, while continually using missions and Instance Dungeons to develop his abilities 32 37 53.

During the Third Great Ninja War, he earns a fearsome battlefield reputation through body-flicker assassinations, swordsmanship, Sage Mode, and large-scale ninjutsu. His pursuit of experience points nearly erodes his humanity during fighting against Sunagakure, but Saori Hyuga intervenes and helps him regain control 149 152.

After assassinating Yagura with his Mangekyo Sharingan, Kyosuke declines Hiruzen Sarutobi’s offer to become Anbu intelligence division head, citing physical exhaustion and emotional instability. He instead becomes a Jonin squad leader with permission to select his own disciples 187 223.

He establishes an independent experimental base in a remote canyon, conducting cloning and Hashirama Cell research while attempting to maintain limits on experimentation involving living people 230. He later becomes a Konoha Elder and Hokage Advisor, assists Minato with relocating the Uchiha Clan to Konoha’s center, and integrates Uchiha personnel into Anbu 331.

Personality

Kyosuke is ambitious, analytical, and intensely focused on self-improvement. He evaluates abilities by their practical combat value, plans upgrades strategically, and treats missions, research, and dungeon rewards as resources for long-term survival 37 71 107.

He can be calculating in political matters, carefully managing how the Uchiha elders perceive him and avoiding direct alignment in the Hokage succession question 5 222. In battle, he is calm, taunting, and willing to exploit enemy hesitation or emotional weaknesses 96 177.

Despite his ruthlessness, Kyosuke shows care for people close to him. He comforts Hiroji after defeating him, accepts Nagisa as a younger-sister-like presence, worries about his squad’s safety, protects Saori, and arranges for Number 7 and Number 13 to regain normal lives through marriage 4 9 157 279 295. He is also self-aware enough to recognize that war, hatred, and his fixation on experience points can distort his judgment 149 223.

• Sage Mode gives him a single horn, six snake-like chakra shadows, altered hair and forehead, and blue chakra imagery around his body 96 162.
