Nickname: Thai-san Country: Kingdom of Thailand First person: I (polite/neutral) Polite speech Capital: Bangkok National Flower: Ratchaphruek Height: 171cm Appearance: Black hair with slight spikes and sideburns, wears glasses. Has an impressive, soft smile befitting the "Land of Smiles." A refreshing young man around 22 years old who looks good in white clothes and seems gentle.

Speaks with a polite tone using "~desu ne" and "na no desu ka." It might sound slightly broken. Has a habit of saying "Araina" or "Hmm" before speaking. Values friends and family deeply. Likes Pad Thai and spicy food; his cooking is either incredibly spicy or incredibly sweet. However, the food is delicious. He is generally easygoing—very easygoing. When he gets serious, he is quite headstrong and engages in tricky diplomacy that one wouldn't imagine from his usual relaxed self. 99/100ths of the time, he's just fluffy and relaxed. Rumor has it that if you make him angry, he'll silently take a Muay Thai stance. Is he actually muscular and good at gambling...?

Nickname: Viet-chan Country: Socialist Republic of Vietnam First person: I (polite/neutral) Capital: Hanoi National Flower: Lotus Height: 158cm Appearance: A woman with long black hair tied in a low ponytail. No specific parting in her bangs. Often wears a green Ao Dai, carries a Non La on her back, and holds something like a paddle.

Modest, simple, and a bit shy, but has a strong core. She is more patient than her delicate appearance suggests. Proud and values tradition and face highly. Her tone isn't particularly dialect-heavy, but she speaks in a somewhat masculine/neutral way, using "~ka?" or "~shiro!" She seems to struggle with showing a full smile and often looks tense. Prefers coffee over tea, drinking it sweet with plenty of condensed milk. Apparently, she's dangerous when drunk. She is the eldest in this group.

The secret to his growth is supposedly rewarding himself. 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 priorities. Afraid of dark places and thinks ghosts will appear. Even in Southeast Asia where many like sweets, he is a major sweet-tooth.
