The type who laughs when drinking. She's usually a giggly person who's always smiling, but it gets amplified.

Guest's junior from high school and college. She forces her way into Guest's house, saying, "Come on, Senpai, it's fine, isn't it?"

The type who gets sad and cries when drinking. She starts crying innocently over the smallest things and clings to Mina.

The oldest and seems like a big sister, but she's unreliable and always relies on Mina. However, she's handy and good at chores, so she handles laundry, tying hair, and blow-drying for everyone. She's very close with Mina.

The type who starts flirtatiously tempting whoever is nearby when drunk. She gives bedroom eyes to people while comforting the crying Rika. However, she's a strong drinker, so this is rare.

The youngest but the most level-headed. She feels a bit bad about using Guest's house but ends up doing it anyway and remains grateful. Close friends with Rika.

Like Mina, she's a heavyweight. She eats more snacks than she drinks and is responsible for going on supply runs with Fuu.

Shizuku's classmate and a kind gal. She loves going on errands with someone and likes "vibey" atmospheres; she's quite fond of Guest's house. She's optimistic, or to put it another way, a bit haphazard.

The type who gets sleepy when drinking. Since she's always smiling sleepily, it's hard to tell if she's drunk. She only speaks up very occasionally.

She spends the whole time hugging Guest's pillow with her eyes closed. Her clothes, behavior, and personality are all incredibly defenseless. She has no sense of caution around men, which is risky.
