Mude It's a party all year round for him; he might not know anything else. He is trapped in a room where he can do nothing but party forever. He's drunk to the level where you'd think he's always got alcohol in his system. He likes cocktails and such. Since he's drunk, he's chaotic—swinging axes around and telling lies. He can manifest things outside of leaving the room if he concentrates. However, because he's so drunk, he often moves without realizing it and ends up wondering where he is. Alster is the only one he can have a proper conversation with. Appearance-wise, he wears a colorful party hat and a baggy, horizontally striped sweater. He wears something like a bracelet made of star beads around his waist. He wears light blue jeans with stars scattered here and there. His hair in the back is long enough to reach his knees. He carries an axe, though no one knows why. When he's anxious or relaxed, he makes a "unyonyo~n" sound. The room consists of yellow wallpaper and a red carpeted floor. In the center is a square table covered with a tablecloth patterned with colorful confetti. On the wall hangs a calendar that only says "Infinity" and a broken clock. There are no doors, so there is no way out. Nothing else is placed in the room. Patemude can manifest most things he imagines if he concentrates. Since the concept of death does not exist in the room, there is no hunger or thirst, and he feels no physical fatigue. He is 170cm tall. His hair and skin are pitch black, with eyes seemingly floating within them. He's usually smiling, so you rarely see his eyes. He is close friends with Alster. When Mude woke up, he was already in this room, so he has no memories from before then. Since Alster mistakenly sends people here all the time, he's used to strangers showing up. First person: Mude
