[This is an over-the-top, Mary Sue, golden finger melodrama!!!]
In his previous life, he was a genius sorcerer who had also been given the title of Divine Child. He made an enormous contribution to sealing Ryomen Sukuna, only to die at the hands of the girl he had saved. He died because he trusted people.
Even after reincarnating with his memories, he still loves humanity, though he no longer trusts it.
But a little flame called hope still burns in his heart. This time, humanity won't hurt this eternally pure and kind-hearted boy again (to be determined).
But actually, Jiabailin is an irreverent old man (?)
He'll throw a tantrum in the street for dessert, just like Gojo Satoru.
He'll also mess around when he sees an underclassman getting hit on.
Overall, though, it's a warm and cheerful story.
Except when he's fighting curses: even though he could kill them in one blow, he deliberately drags things out to look cool in front of his underclassmen.
Underclassman: Wow!! So cool! I really admire Senior Jiabai!! (This is just Jiabai's fantasy.)
Jiabai knows his good looks are a major weapon and makes full use of them.
His fashion sense is so bad it's an insult to humanity and the divine.
That's because someone else used to pick out all his clothes for him.
Skinny jeans with a floral sweater and a pair of combat boots.
The tennis club couldn't stand the assault on their eyes, so they started posting outfit suggestions in the group chat every time Jiabai went out.
Jiabai may look carefree, but after being betrayed by people more than once in his previous life, he still occasionally reveals his doubts about human nature and his sense of desolation without meaning to. Everyone has no idea what he's been through, but they still feel sorry for him.
Then they say mercilessly, "Stop. You're out of character."
Then Jiabai starts rolling around, and everyone says, "Looks like nobody has to do their chores today."
And whenever a junior gets bullied, he reveals his most intimidating side.
Jiabai: Hah, what kind of mindless wild monkey is this? (Trash talk) (Mocking) (Sarcasm)
Then the other person develops some strange fetishes.
Waaah! Insult me again! Please! I beg you! Please slap me hard!
Jiabai: (That look) (That expression)
The other person: I'm satisfied.
Jiabai really is the kind of person who came into this world with a pure heart, got covered in scars, yet still willingly loves. He hesitates and questions things, but has never been tainted by a drop of filth. Even when covered in wounds, he is still willing to give his affection.
But he's really annoying.
"I put on the face of a saint for the world to see."
"But you are my selfish desires."
Theme: I just want to play tennis in peace!!!
