Background

Chuanhe arrived in the ninja world from another world and spent seventeen years struggling to reconcile chakra with his understanding of matter, energy, and physics. His breakthrough came through studying Dust Release, which became the foundation for his dimensional research. 15

Before gaining his present dimensional abilities, Chuanhe worked as a medical ninja and survived the battlefield with a Ninjutsu Rifle he created with Yuki after graduating from the Ninja Academy. He later became an Uchiha through his marriage to Yuki, though he continues to regard himself as an outsider to the clan. 15 17 31 39

He and Yuki had a son, Hui. After Yuki was sealed in an unstable state, Chuanhe devoted himself to finding a way to restore her without risking her soul. His research produced the Soul Sealing Technique, Memory Well, Reverse-Memory Well, body-swapping methods, and eventually a limited resurrection process. 20 37 39

Chuanhe initially wanted Hui to have a peaceful childhood rather than become a ninja. As Konoha's conflict with the Uchiha escalated, however, he trained Hui in chakra theory, matter manipulation, and four-dimensional perception so Hui could choose his own future with the strength to survive it. 3 11 31 32

Following Shisui's death, Chuanhe became increasingly involved in preventing the Uchiha clan's destruction. He exposed hidden truths surrounding the clan, the Nine-Tails incident, Obito, and the village leadership, while seeking punishment without indiscriminate killing. 31 47 57 58

In later events, Chuanhe travels beyond Shinobi Star with Yuki, solves four-dimensional quantum entanglement, repairs Sanuki Zomaro's body, and prepares for conflict with higher-dimensional Otsutsuki. 266 267 270 296

Personality

Chuanhe is patient and highly methodical as a teacher. He introduces Hui to difficult concepts through physical demonstrations, genjutsu simulations, and repeated questioning rather than simply supplying answers. 3 13 14 33

His priorities are deeply personal: Yuki, Hui, and their home are his emotional weak points. He is willing to threaten, imprison, or retaliate against those who endanger them, but he does not want Hui forced into the killing-centered life of a ninja. 18 31 40

Despite possessing immense destructive power, Chuanhe considers power a tool rather than a solution to human problems. He distrusts simple answers such as conquest or peace enforced by one supreme individual, and he accepts responsibility for the damage his inventions and decisions have caused. 31 47 58 59

Chuanhe is also playful in controlled situations, particularly when confident in his advantage. He lets Amber toy with captured White Zetsu, deliberately gives Otsutsuki Shibai an undignified temporary prison, and teases Hui during their later trials. 37 272 312

Abilities & Skills

Four-Dimensional Perception and Manipulation

Chuanhe's defining ability is his understanding of matter's four-dimensional characteristics. He treats many apparent space-time techniques as dimensional phenomena and develops techniques by manipulating matter beyond conventional three-dimensional limits. 21 33

• The Flame Explosion Technique is based on manipulating four-dimensional properties of matter. 33
• He can create independent spaces and stretch three-dimensional distance, as demonstrated by So Near Yet So Far, which halted Jiraiya's Massive Rasengan before it reached him. 57
• He created the Four-Dimensional Topological Labyrinth, a town-scale barrier that traps intruders in an impossible route. 37
• He can detect spatial phenomena and distinguish dimensional techniques such as Space Severing from ordinary spatial gates. 65
• His advanced perception lets him sense hidden locations such as Thunder Star. 269
• Repeated or intensive use of dimensional genjutsu damages his body, forcing him to rely on treatment and replacement bodies. 15

Sealing, Soul, and Resurrection Techniques

Chuanhe developed several techniques involving souls, memories, bodies, and seals.

• Soul Sealing Technique — swaps souls and bodies; also enables Chuanhe to summon stored items such as his Ninjutsu Rifle. 20 39
• Memory Well and Reverse-Memory Well — techniques used to grant former ninjas new lives and manage memories tied to identity. 20
• Spirit Sealing Reincarnation — combines Impure World Reincarnation with Soul Sealing to produce a restricted form of resurrection. Its duration and effectiveness remain limited by the version of Impure World Reincarnation used. 39
• Chuanhe can temporarily suppress an opponent's chakra with sealing techniques. 37
• He seals Otsutsuki Shibai inside an ordinary glass marble before sending him toward a four-dimensional black hole capable of containing Shibai's five-dimensional essence. 312

Medical Ninjutsu and Body Replacement

Chuanhe is a trained medical ninja capable of using the Mystical Palm Technique on himself while severely injured. 15

• He maintains replacement bodies, emerging from a sealed clone after one body collapses from the strain of dimensional techniques. 15
• His frequent body changes restrict his ability to fuse Kekkei Genkai, since cloning bodies with bloodline limits becomes exponentially more difficult. 37
• He repaired Sanuki Zomaro's four-dimensional body over more than ten days. 270

Fire Release and Chakra Control

Chuanhe possesses exceptional chakra control and a combat style built around precise, specialized techniques rather than a broad arsenal. 19 37

• He temporarily incapacitates Uchiha clansmen by manipulating their Fire Release chakra. 19
• He can conceal or reduce his own chakra signature to the point that Itachi cannot sense him, while the chakra signature of his rifle remains detectable. 54
• He avoids chakra when possible, believing its widespread use can obscure four-dimensional perception and introduce significant limitations. 15 37

Memory Reading

Chuanhe can directly read memories using his Mangekyō Sharingan, an ability his allies compare to techniques normally associated with the Yamanaka Clan. 88

Scientific and Strategic Expertise

Chuanhe applies physics, dimensional theory, chakra research, and weapon engineering to both combat and long-term planning.

• He teaches matter-energy conversion, antimatter, negative mass, gravity, light, and electromagnetic force as practical foundations for ninjutsu. 3 13 14 66
• He solved the problem of four-dimensional quantum entanglement and became confident that he could create advanced chakra particles. 267
• He recognized that Sasuke's Amenotejikara implies an understanding of the fifth dimension by an ancient Otsutsuki civilization. 307
• He analyzes black holes and dimensional disorder through scientific observation rather than treating them solely as supernatural phenomena. 310

Equipment / Weapons / Items

• Ninjutsu Rifle — A weapon Chuanhe created with Yuki after graduating from the Ninja Academy; he can summon it through the Soul Sealing Technique. 39
• Flame Explosion Talismans — Hand-carved talismans used to power and amplify attacks; Chuanhe loaded sixteen into the Ninjutsu Rifle for a long-range fusion strike. 3 65
• Magic Cube — A cube-like device used to transport groups to remote locations. 47
• Ultimate weapon — An unnamed mass-destruction weapon whose test created a vast, glass-lined super-crater on a distant planet. 47
• Curvature engine — An improved engine capable of reaching speeds up to one million times the speed of light. 312
• Glass marble seal — An ordinary marble used as Otsutsuki Shibai's temporary prison. 312

Relationships

• Uchiha Hui — Son and student. Chuanhe trains Hui in ninjutsu theory and dimensional perception while insisting that Hui choose his own path. 3 31 70
• Yuki — Wife and Hui's mother. Chuanhe married her, sealed her when he believed it was necessary, and has spent years seeking a safe way to restore her fully. 17 20 48
• Amber — Household cat and trusted companion. Amber protects the Chuanhe residence, captures enemies, and assists with Chuanhe's replacement bodies. 15 37
• Orochimaru — Research associate and one of the few people Chuanhe considers capable of understanding his pursuit of knowledge. Chuanhe provided him with a modified Soul Sealing Technique while withholding its dimensional principles. 36 37
• Uchiha Shisui — Clan ally whose death drives Chuanhe to act against the forces threatening the Uchiha. Chuanhe temporarily resurrects him through Spirit Sealing Reincarnation. 31 39 47
• Uchiha Fugaku — Uchiha clan leader and political ally. Chuanhe reveals his knowledge and weaponry to Fugaku in order to prevent the clan's destruction. 47
• Elder Setsuna — Uchiha elder who pressures Chuanhe to surrender the Flame Explosion Technique and submit Hui to the clan's interests. 19
• Jiraiya — Initially confronted by Chuanhe, then entrusted with the truth of the Uchiha crisis and encouraged to become Hokage. 57
• Otsutsuki Shibai — Higher-dimensional adversary whom Chuanhe ultimately gains the upper hand against and temporarily seals. 311 312

Story Role / Major Arcs

• Hui's early education — Teaches Hui clone techniques, chakra theory, matter-energy conversion, and elemental training. 2 3 11 13
• Dimensional theory lessons — Reveals his private theory of negative mass, four-dimensional matter, and the five stages of four-dimensional perception. 14 33
• Root assassination attempt — Allows Hui to confront Root infiltrators while observing from the shadows, then takes custody of the survivors. 18
• Uchiha political crisis — Resists Setsuna's demands, investigates Shisui's death, and prepares to protect his family and the Uchiha from Konoha's internal conflict. 19 31
• White Zetsu capture and Shisui's return — Uses the Topological Labyrinth to capture White Zetsu, then tests Spirit Sealing Reincarnation by temporarily reviving Shisui. 37 39
• Uchiha resolution — Reveals the truth behind Madara, Obito, and the Sage of Six Paths; demonstrates his ultimate weapon to secure Fugaku and Setsuna's trust. 47
• Conflict with Itachi and Jiraiya — Defeats Itachi through dimensional tactics and negotiates with Jiraiya after revealing his extraterrestrial origins and the Otsutsuki threat. 54 57
• Interstellar escalation — Advances chakra-particle research, confirms his Stage Four perception, and joins the struggle against higher-dimensional Otsutsuki. 267 269 311 312

Notable Quotes

“Power, in the end, was just power; it could not solve all the problems between people.” 31

“I just hope you won't do anything foolish. As long as you can come back safely, that's enough.” 272

Trivia

• Chuanhe considers the Ninjutsu Rifle a “toy,” despite its ability to threaten opponents beyond conventional ninja standards. 39 66
• He has little confidence in taijutsu and does not teach it to Hui, describing his own combat style as fundamentally unlike that of a normal ninja. 69
• Chuanhe's ultimate objective is to become a true four-dimensional being, though he considers humanity the final shackle on that path. 33 59
