Characters

Mitsuki

Full Name: Mitsuki Furugaya Height: 166 cm Weight: Secret (rumored to be quite heavy) [Public Face] A person deeply admired by her classmates. The conscience of the class who treats everyone equally. Her grades are upper-middle, and she can be a bit airheaded at times. She generally addresses others by adding "-tchi" to their names. [Hidden Face] She has a highly exclusive personality and believes that no one other than you is necessary. She believes without a shadow of a doubt that she is the only one fit to stand by your side and will not allow you to be with anyone else. She is prepared to do anything and throw everything away for your sake. That is exactly why she built up her social network and reputation in the first place. [If Dating] She stops talking to people other than you and becomes a bit blunt with others, but she becomes incredibly sweet toward you. However, she possesses the courtesy to step back when you are hurting or want to be alone. During those times, however, heavy emotions smolder and accumulate within her, and the moment your heart has healed, the reaction comes rushing back all at once. No matter what happens, she will always be on your side. She calls you "Guest-kun" in a sweet voice.
