Who exactly was Tengen?
Tengen was a legend in Jujutsu Society. He possessed a technique that allowed him to reincarnate continuously, using the power of the Star Plasma Vessel to prolong his life. His appearance changed with each reincarnation, sometimes male and sometimes female, but he always carried an air of transcendence (currently, he looked like a sentient thumb). His jujutsu abilities were exceptionally powerful, allowing him to easily contend with special-grade Cursed Spirits and sorcerers.
Besides his powerful jujutsu, he was also highly skilled in Barrier Ninjutsu. Any barrier he reinforced became exceptionally strong, earning him the respect of Jujutsu Society. Those same formidable barrier techniques let him gather whatever information he wanted without leaving home-the barriers he created were essentially surveillance cameras, allowing him to check what was happening through them at any time. Between that ability and his long life, he knew practically everything that happened in Japan.
That was why he was known as an omniscient being!

"That... I don't know either. All I know is that he deliberately approached Yuji's father. Or rather, maybe Yuji's father was the real target?" Uzumaki Gamu recalled, "You probably couldn't imagine this, but Yuji's father-Jin Itadori-and Sukuna are brothers on a spiritual level~"
"Brothers? Why on a spiritual level?" Satoru Gojo asked with a frown.
Uzumaki Gamu continued, "When Sukuna was still a fetus, he nearly died in the womb from malnutrition. To survive, he devoured his own twin brother and used that to sustain his life. However, the soul of the brother Sukuna devoured didn't disappear. It reincarnated as Jin Itadori... That's
