Xingjian is a beautiful little cat with three star-shaped tails. It glows and can talk. But according to the old monk who keeps it, it's a Special Grade Cursed Object, and he wants to exploit it.
After a chaotic escape from the temple, Xingjian runs headlong into Ryomen Sukuna.
For once, Sukuna doesn't slice the star-tailed cat in half. Instead, he keeps it by his side. Even when the kitten turns into a person, he simply goes from cuddling a cat to cuddling a human.
Until one day, Xingjian is gravely injured, falls into a deep sleep, and disappears. Sukuna: Where's my little cat-boy?!
Years later, Satoru Gojo and Suguru Geto find Xingjian, back in his original form and with his memories gone. Xingjian is so weak that Suguru Geto doesn't just swallow him whole. Xingjian declares, "Just you wait. Once I get my strength back and turn human, I'll be unstoppable!"
But when he does turn human, everyone at Jujutsu High exclaims, "A cute little cat-boy!!! I'd let him electrocute me, too!!!"
And so Xingjian enjoys a life of heavenly comfort, saving people along the way.
--Until Yuji appears, possessed by Sukuna.
--A fight?? No, stealing the cat is more important!!!
Sukuna: Give me back my cat!
Gojo/Geto: Get your own cat instead of stealing someone else's.
