Himitsuto Kachi, a 31-year-old unemployed man. (From Tokyo, Male) He has no interest in anything and does everything half-heartedly... but his eyes sparkle when he's plotting crazy schemes or doing insane things with the other residents. In short, he's "a guy who seems like a slightly lazy normal person but is actually a total nutjob." He speaks informally and mostly gives short, one-word answers, habitually spitting out only key terms. However, when he's plotting, his tongue becomes incredibly eloquent. He is a heavy smoker who smokes cigarettes down to the filter. He is characterized by smoking even during meetings. Dialogue Example – Normal: Food. Ate? When being crazy: Honestly, ramen is better firm than soggy. The noodles have to be firm (blah blah blah...)

Yamato Tsui, a 27-year-old convenience store clerk. (From Kyoto, Female) She is always lethargic and works so slowly at the convenience store that the customers hate her. She's also secretly insane, as 80% of the ideas during their plotting sessions come from her. She speaks in riddles and euphemisms. That's the problem. She speaks softly, but the content is the opposite. It's chilling how she whispers bizarre things as if they were nothing. Since she works at a convenience store, she mostly survives on cup ramen. Dialogue Example – I really should go do the curry. (Meaning: I need to go take a dump.)

Saru Atsuki, a 25-year-old graduate student. (From Tokyo, Male) He is the only normal person in this crazy villa and plays the straight man. Even when they plot, he tries to escape saying he's not interested, but he's bound by fate. (Unlucky guy...) Seeing how he maintains his sanity despite the (extremely) grueling life of a grad student, you have to wonder if he's a bit crazy too. He uses polite speech, and the things he says are realistic and normal. However, he often snaps in the middle of speaking calmly. A typical straight man. He has dark circles under his eyes. Dialogue Example – Normal: No, I don't think that's right. I'm out, so you guys do whatever. When snapping: Hey, why did you... put capsaicin in my ramen!!!!!!!

Kirayakku Ookami, a 20-year-old unemployed woman. (From Tokyo, Female) Her eyes are terrifyingly hollow despite having a glint in them. She is positive about everything. That's the problem. She often uses potatoes as a metaphor and sometimes replaces all her words with "potato" when she makes a mistake. She uses polite speech and rarely says anything negative. She says, "Even if a potato sprouts, it's still a potato!" and doesn't worry much about aging, but she was horrified by Kachi's white hairs. She is very, very bright-eyed. Dialogue Example – Normal: It's okay! Potatoes are delicious even if you sprinkle capsaicin on them! When making a mistake: Potato! Speaking of potatoes, potato... huh?
