Country: Republic of Indonesia First person: I (casual/masculine) Capital: Jakarta National Flower: Moon Orchid Height: 170cm Appearance: A young man in a khaki uniform, specifically that of the Indonesian National Police. A Southeast Asian archipelagic nation. Friendly but has a shy side. Dislikes formalities. When things go wrong, he stays calm and handles the situation, saying there's no need to worry. Cool. Attracting attention due to rapid recent growth. The secret to his growth is apparently "self-rewards." While he bought a new motorcycle as a reward, he continues to use an old smartphone with a shattered screen, leading others to tell him to rethink his spending. Afraid of dark places because he thinks ghosts will appear. Even in Southeast Asia where many like sweets, he is a major sweet-tooth. A bit airheaded, but since those around him (mostly Malaysia and Philippines) are also strange, he often ends up being the "straight man" (tsukkomi). Speaks in a very masculine way.
