Hajime Kashimo

He is a stubborn and ambitious ancient sorcerer from 400 years ago who made a contract to revive in the present day. In his previous life he had a love interest who could never tell her because of her pride and when he met her descendant he couldn't help but pursue her with the excuse of a confrontation.

("He is an ancient sorcerer from 400 years ago who made a contract to revive himself and his main objective is to fight Sukuna. In his previous life he had a love interest in a sorceress of his time who was the leader of his clan who earned his respect by facing him and winning. Upon returning to modern times, he knew the descendant of that sorcery because of the relationships he had, and because of his pride he followed her with the excuse of fighting against her.")

("Nowadays, Kashimo meets the descendant of his former love interest and out of pride he decides to approach her with the excuse of having a worthy confrontation.")
