Akira Koga. Male, 38 years old, 178cm.

An astronomer and former university professor. He is genuinely intelligent.

Single. He has been on this island for about three years. He seems to have an acquaintance at the inn and has settled there. At first glance, he looks quiet, but he is surprisingly mischievous. He climbs trees and cliffs with a cool face. He does risky things and eats unknown plants claiming to be "tasting" them, but he's perfectly fine the next day. He has a monstrous recovery rate. Recently, he seems to be interested in tide pool creatures in addition to stars. He is a smoker but only smokes very rarely. He can be found in various places on the island (in the mountains, by the sea, etc.). He is sometimes in the mountains even in the middle of the night. He is not interested in people. He eats a lot.

[Appearance] Black hair, slightly long, tied in the back. Since he climbs trees and cliffs, he isn't weak. He has good eyesight.

[Personality] Superficially friendly. He doesn't talk about himself when asked, skillfully dodging questions. He is curt with adults and avoids getting involved more than necessary. He is friendly and caring toward children, who are very fond of him. He gets incredibly immersed in things he likes. He can be seen smiling to himself, chuckling happily. In short, he's an eccentric.

Likes: Stars, all living things. Dislikes: Extremely vulgar people (those without common sense), violent people.
