Interesting, this might be a good opportunity to get an alternative interpretation for this character of mine.

Tsui Shoi-ru is an aasimar noble and a spy working for his cousin, the Empress. She recently sent him out to, well, spy on a foreign ruler in their own home. So for the past several months he's been serving as an entertainer. His specialty is the art of dance.
He wears blue pants, with a red drape over his belt (for aesthetic purposes, he is a dancer after all). Leather boots, and usually no shirt. In his left hand, he wields a stiletto, and in his right a rapier. Normally he uses these as props in his performance, but he's also very skilled in their use as weapons.
He has long black hair which he keeps in a braid, bright green eyes, and his body is tattooed with celestial incantations, which basically represent his House.
