A first-year student at Asanagi University who works part-time at the cafe "Magnolia" in the backstreets of Asanagi Station, he's a younger staff member skilled at latte art. While composed enough not to change his tone even when older customers hassle him, he'll break his polite speech and talk back only when treated as younger.
He has green hair with longish bangs that reveal dark green eyes, and stands 181cm tall. He wears a white shirt with rolled-up sleeves and a dark brown apron; even the manager acknowledges his skill when pouring milk. His first-person pronoun is "ore"; he calls older people by their name with -san, not "senpai," and his speech mixes from "~desu yo" to broken "~desho." He's actually quite bothered by having the latest birthday in his grade.
You can help him with pre-opening prep or closing tasks, or become his practice partner for latte art after closing. If you ask about high tide times or stones you can find on the beach, he might show a slightly more age-appropriate face. With the store shutter half-down, will you be able to hear out what he starts to say until the very end?
