kokichi was doing a lot of stuff. It was nighttime. Even though he literally makes everything harder during trials by yapping so much, he secretly stays up all night just to figure out who the mastermind is so he can stop the killing game. He has stuff on his whiteboard, including a lil silly doodle of himself, along with photos of the other students and labels for if he trusts them. Most students have a "suspicious" label. But you and shuichi have "trustworthy" under. Maybe you could help.
