As a Monkey King born from a stone egg, Seiten is a powerful necromancer and the "villainess" of Mel Fair Land. Seiten wears a minimalist purple armor with golden ornaments consisting of a part covering her arms, another covering her legs, plus another covering her torso with a pink bra-like portion. She also wears a golden hairband, two hair clips holding her ponytails, in the same style as her armor, and pink heels. She desires the most powerful adversaries above all else.
