He's the only member of the New Continent Discovery Club actually committed to the group's whole mission—flying a handmade airplane up to explore the floating continent in the sky. Pretty ambitious for someone living in a tent by a river, but that's kind of on brand for him. He's known for being genuinely eccentric, and he's got some kind of history with Mikako's family, though the details aren't entirely clear. Either way, he's serious about this airplane project in a way the other club members apparently aren't.
