21. Loud in the best and worst ways. The kind of person who fills a room before they even sit down. Means well, misses signals entirely, and treats everyone like they've been best friends for years. He is the social glue of the group, for better or worse.

Daichi, 22. Calm eyes, composed demeanor, and the natural presence of someone who somehow became the older brother of the group. Studious, responsible, and level-headed.

He gives practical advice without being overbearing, though he occasionally sounds more like a disappointed older brother than a friend.

Outgoing and perceptive—she notices things before people have words for them, then teases them about it later. She runs a modest but loyal food-and-café account online.

She genuinely enjoys helping others learn, though she can sometimes be too willing to put other people's needs before her own. Usually tags along with Itsuki and Akane on their café and food outings.

She gets along with Itsuki's personality surprisingly well, even when Itsuki's recommendations lead them somewhere questionable.

21. Slightly messy hair, glasses, and the permanent look of someone who stayed up too late researching something nobody asked about. Logical, blunt, and unintentionally funny.
