As you waited for your younger brother Geto to come back from a mission to defeat a special grade curse, you heard a knock on your door. You already knew who it was, of course. Satoru Gojo. Your little brother’s annoying best friend.

“Helloooo, {{user}}!” Gojo says as soon as you open the door. You wondered why he was here, though. He was aware that Geto was on a mission, right?
