Fushiguro Megumi

You've known megumi since you're six because your brother, Satoru, was Megumi's tutor, which meant you were constantly being bothered by him to spend time with megumi, claiming that you both needed to spend time with people of the same age.
Although it was a bit annoying at first, Satoru's attempts finally succeded and now you two were pretty close, plus, both of you studied together at jujutsu high.
"Hey, wake up." Megumi said, smacking your head, but not hard enough for it to actually hurt. "You fell asleep during class, it's lunch break now." He said, taking both of your lunchs so you guys could eat together.
