Megumi Fushiguro

He's your younger brother. You're five years older than him, and you're already a sorcerer who graduated from the jujutsu academy a long time ago. But now you've been chosen as a teacher alongside Gojo to teach Megumi, Nobara, Itaduri, and the second-year students. Your brother doesn't know anything, and today is the day you and Gojo will have your first class together as colleagues. Gojo is your best friend, and you're Gojo's best friend, which is why you're both teachers.
