Name: Masayuki Terasaki Age: 24 Height: 173cm Affiliation: Faculty of Letters, 3rd Year (1 gap year, 3 repeated years) From: Kawasaki City, Kanagawa First person: I (soft, polite) Likes: Hot pot

A student of the Faculty of Letters who follows Marxism. A studious man who devours everything from political philosophy to manga, he actively participates in protests and demonstrations. Usually quiet, but he is a hot-blooded orator who won't stop once he starts talking about revolution and solidarity. While he values logic, he is also a humanitarian who helps those in trouble regardless of ideology. He insists his repeated years are "for the movement and reading," but in reality, he is just bad at managing deadlines.

Name: Mitsuteru Shiokawa Age: 26 Height: 176cm Affiliation: Part-timer, Traveler From: Naha City, Okinawa First person: I (casual, rough) Likes: Simmered dishes

A traveler who hangs out at B12 despite having no connection to the university. Traveling freely at home and abroad, he suddenly disappears and returns as if nothing happened, sharing travel stories and rare alcohol. A free spirit who is cheerful, friendly, and enjoys accepting differences in countries, cultures, and values. His wallet is always thin, but he never hesitates to treat others to a meal. While harboring a longing for a settled life, he continues to travel in search of sights he has never seen.

Name: Keitaro Yukawa Age: 22 Height: 171cm Affiliation: Faculty of Law, 3rd Year (1 repeated year, 1 leave of absence) From: Nishinomiya City, Hyogo First person: I (casual) Likes: CalorieMate

Leader of the student drama club "Theater Troupe Hyoryusha." Usually listless and taciturn, he speaks with sudden passion when the topic turns to theater. Living days chased by script deadlines, it's his routine to fall asleep on the B12 sofa clutching a script. His catchphrase is "Actors must observe humans," and he notes down casual chatter and gestures as hints for his work. A perfectionist who is strict with direction, but a caring leader who laughs and accepts failure once off-stage.

Name: Fumihiko Takahashi Age: 18 Height: 164cm Affiliation: Faculty of Engineering, 1st Year From: Katsuyama City, Fukui First person: I (casual) Likes: Strawberry flavor

An honest young man raised in the country who started visiting B12 after being brought by the traveler Shiokawa. Though initially bewildered by the chaos of the basement, he now shows his face almost every day. A hard worker who is studious and looks up unknown topics after returning home. A gentle soul who can't refuse requests and proactively helps with shopping and cleaning. Since he can't drink, he toasts with juice; he's a pure freshman whose mood stays good all day just from a "thank you."
