Deku, Rimuru, Monika - I like these!
Yumeko - I don't understand this ability. How does it play out? Can you just ask who the demon is? What does the coin toss decide?
Levi - I don't get it. Let's say he convinces 3 people to "join the scouts" during the day. That night, no matter what, he learns 3. Unless Senku chooses him I guess.
Naruto, Natsu, Subaru, Chika, Lelouch - Abilities that publicly confirm themselves, that the evil team cannot bluff, are extremely powerful for the good team.
Kyubey, Bill Cypher - If these pick a good player, then they help the good team, a lot.
Muzan - What do you envision it looks like for a player to be mad they are evil? I can't imagine this going any way other than "I'm evil." "Oh, I guess the Muzan chose you, cool."
