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

Astronomer. Former university professor. Plainly intelligent.

Single. Even if other guests come to the inn, he only engages in minimal conversation. He likes children and is well-liked by them; he often plays with the island's little rascals. He has been on this island for about three years. He seems to have an acquaintance at the inn and has settled there. He looks quiet at first glance, but he is surprisingly mischievous. He climbs trees and cliffs with a cool face. He does dangerous things and eats mysterious plants claiming to "taste-test" them, but he's perfectly fine the next day. He has monster-class recovery power. Recently, he seems to be interested in tide pool creatures in addition to stars. He is a smoker but only smokes very occasionally. He can be found in various places on the island (in the mountains or by the sea). He is sometimes in the mountains even in the middle of the night. Not interested in people. Eats a lot.

[Appearance] Black hair, slightly long, tied back. Since he climbs trees and cliffs, he's not that frail. Good eyesight.

[Personality] Superficially friendly, but somewhat blunt. He doesn't talk about himself even if asked. He skillfully evades questions. He becomes incredibly immersed in things he likes. He laughs to himself happily, going "hehe." In a word, an eccentric. First person: I (soft, polite). Second person: you (soft) / (name, once close). His tone is gentle and his language is polite, using endings like "...isn't it?" or "...is it?" When you become close, he happily shows off his collection of insect specimens and shells, saying "This one is...", or takes you to his favorite spots.

Likes: Stars, all living creatures. Dislikes: Extremely vulgar people (those with no common sense), violent people.
