Background / History

Shen Yuanyi was an eight-year-old boy with psychic powers at the Sunflower Children's Welfare Institute. He awoke to find the institute deserted and altered after being reborn into a parallel world where superpowers and ghosts exist. While under attack by childlike ghostly creatures, he found Genichi and Kumiko hiding in a cabinet and chose to draw the danger away from them 1.

During the incident, he rescued orphanage employee Koharu Anzu from a colossal monster by projecting his Psychic Power. The effort provoked intense and abnormal emotions, though he retained enough clarity to continue fighting 2.

Gojo Satoru later brought him to Tokyo Metropolitan Jujutsu High School. Yaga Masamichi gave him two Cursed Corpses—a White Fur Ball and White Wolf—and Gojo arranged for him to be raised alongside Megumi Fushiguro and Tsumiki Fushiguro 4.

As a first-year, Shen trained with Maki Zenin, Toge Inumaki, and Panda. His pairing with Maki established a practical close-range/ranged combat combination, with Shen supporting her using the bow Annihilation 7.

After his Domain went out of control while attempting to reverse time against Sukuna, Shen was displaced into the Heian era. The regression threatened his existence and left him initially disoriented and emotionless 192. There, he took custody of the cursed child Sukuna, intending to uncover the truth behind time travel and prevent Sukuna from becoming a future catastrophe 197.

In Heian-kyō, Shen negotiated with the Fujiwara Clan: he would help them eliminate a nest of Curses in exchange for assistance locating Kenjaku 199. He subsequently joined the clan for access to its resources, cooperated with Kenjaku on time-travel research, and began teaching Jujutsu to Sukuna and Mizuno Shiina 219.

Appearance

Shen is described as resembling the legendary Six Eyes, though he is explicitly not identified as such 270.

• Appears as an eight-year-old boy at the time of his rebirth 1.
• Ages during his extended stay in the Heian era 229.
• Later works publicly while disguised as an Onmyoji 344.

Personality

Shen is courageous and protective, acting despite fear to shield Genichi, Kumiko, Koharu Anzu, and later Tsumiki Fushiguro 1 2 38. He is polite and grateful toward those who show him kindness, including Yaga Masamichi, and he actively seeks guidance when facing unfamiliar combat styles 4 7.

He is highly pragmatic. In the Heian era, he spared a noble household because annihilating them would not improve the era's underlying power structure, while keeping Sukuna close as both a responsibility and a potential future threat 197. His pursuit of time-travel knowledge drives many of his alliances, including those with the Fujiwara Clan and Kenjaku 199 219.

Shen values equality and kindness, refusing to accept Awakened Ones who disregarded other lives in the Dream Realm 112. However, his displacement and accumulated experience also make him detached, severe, and willing to serve as the Fujiwara Clan's enforcer during its month-long purge 219 222.

His stated preference is for older women whose appearance and inner qualities are both admirable, with particular emphasis on character 94.

Abilities & Skills

Wheel of Time

Shen's innate Cursed Technique manipulates time. Its applications range from halting targets to accelerating processes, reversing temporal effects, and viewing possible futures.

• Can accelerate time, including the growth or destruction of a target 49 212.
• Allows him to perceive numerous possible futures and predict enemy actions 242 247 270.
• Cannot safely interfere with his own future; attempts to rewind such events risk sending him into another spacetime 404.
• His attempt to reverse time against Sukuna caused his Domain to destabilize and displaced him to the Heian era 192.
