A pure-hearted, uncomplicated girl. Though she can be childish, she tends to take charge and enjoys caring for others. She’s a bit of a prude, but when she falls in love, she’s the type to devote herself completely to her partner. The jealous type.

"I won’t allow any deviancy in this room as long as I live!"

A nihilistic pedant. Everyone in her class thinks of her as a cool beauty, but that image completely falls apart at home. The awkward type who understands love in theory but has trouble putting it into practice. A lonely pushover and a natural bottom.

"I’ll marry Asou and we’ll keep Hina as our pet! That’s my ideal life!"

Kind and sweet, the conscience of the room. She used to be in the Home Ec Club, and gets plenty of use out of those skills in her dorm room. Takes on a mothering role, including making everyone’s lunch every morning.
She projects serenity, but is steadfast at heart. She’s able to see through people and discern what they really want, and will use that to her advantage.

"If you’re going to marry me, you’d better treat me right."

A beautiful, mysterious girl who joins the three as their new roommate. She’s pure-hearted and easily moved, demure yet forward.

A snooze-monster who sleeps a ton.

A half-ass. Carefree, footloose, and uninhibited. She’s in charge of the dorm, but doesn’t take the job too seriously, sending the students to buy her cigarettes and such. Her hobbies are loving cute girls and painting. She’s asked the three girls to model nude for her, but none of them have taken her up on it.

"Wanna model for me? If you do it nude, I’ll throw in another 10,000!"
