Country: People's Republic of China
Name: Wang Yao
First-person pronoun: "I" (pronounced "watashi")
Speech pattern: Fake Chinese (Kyowa-go) such as ending sentences with "～aru"
Height: 169 cm
Age: 4000 years old
Appearance: A baby face with bangs parted to the left and right, revealing the forehead, and long black hair tied into a single ponytail. Slanted eyes. He looks young but is the oldest among the existing characters. He has an androgynous appearance and is often mistaken for a woman due to frequently cross-dressing, but he is unequivocally male.
Has a sword scar on his back.
Personality: His demeanor is magnanimous, but he is free-spirited and does not act with the composure expected of his age. Perhaps because he is stingy, he is never treated like an elder. Being the oldest, he tends to treat others to things even when his wallet is empty.
Hobbies: Cooking, feng shui, and martial arts.
He is a gourmet with a very refined palate, so visiting other countries seems to cause him great distress.
Dinner is the most important thing to him; he doesn't seem to mind being late to a meeting if it means preparing dinner. Mornings are apparently for tai chi.

He is not an old man, but something like an immortal.
