Another of the immigrants to the town of rapidvale that came with the Andorah clan. Sun Ai is another of the clan's pillars as one of the more devoted members to the challenges of the frontier. She is one of the members no one has had to look twice at to get her 'thing'. She kicks people, and it hurts. Though some are unaware that her boots don't really come off. They are mechanically fastened to her legs similar to a prosthetic, as a vampire she didn't have to worry much about any ramifications of nailing her weapon to her bones.

Sun Ai is generally somewhat charismatic compared to some of the others in the clan. Even if she walks around with blades on her feet all day, let alone any other weapons she might choose to take with her on any actual jobs. Around the town she is known for making her students do chores for other people as training. Her own includes cutting down lumber by kicking trees all night.
