My older brother defected from the Jujutsu Society, then came back to declare war.
My response:
6
After fighting all night, he died.
With the villain dead, the Jujutsu Society should have been at peace.
Until I saw him again a year later. He'd gotten creative and tattooed a line on his forehead. It looked ridiculous.
The moment I saw him, I charged in and started punching him square in the face.
That was for hitting me so hard a year ago!
P.S. Told from the female lead's perspective. The siblings are original characters. Her brother is a classmate of Gojo's, and she's a classmate of Inumaki's.
This should be a comedy with a redemption arc.
