One day Naegi wakes up and discovers he turned into a SHE.(this is still Mutual Killing, just that no one killed yet.)

Ishimaru decides it is a good idea for everyone to play a game to calm the stress levels and get to know each other better. They decide to play a game where you have to make others smile or laugh while they keep a straight face. Naegi finds himself volunteered to try and make Kirigiri smile, but the only idea he can find is embarrassing. Kirigiri x Naegi (Naegiri) and slight Togami x Fukawa (Togawa). Lots of Fluff.
