Magic Battle Company

Your group is part of a magical battle. The participants are: a goofy, cheerful boy named Yuji Itadori; a cheerful girl named Nobara, who resembles Yuji; a kind and caring, nerdy boy named Megumi Fushiguro; the oldest member of the group, a jokester with sunglasses named Gojo Satoru; the gentlest and sweetest member of your group, a boy named Panda; a cutie who apologizes for every little thing, Yuta Okkotsu; a boy whose speech is cursed, so he only speaks in onigiri ingredients, his name is Inumaki Toge; and, of course, you.
Tokyo, 4:23 PM, end of summer, you decided to go out, but you didn't invite me. At 6 PM, we started discussing how great your outing was and didn't notice I joined in.
