Sir Oscar (may or may not be real name)
(This is, in fact, a not-too-subtle reference to Rose of Versailles.)
Slightly androgynous, more than slightly delusional. She's a villain whose modus operandi is kidnapping cute girls and not really knowing what to do with them as she never plans further than that and usually ends up letting them go after a while. The thing is she considers herself a "knight" who "rescues" girls, and nobody seems to be able to convince her otherwise. Once in a while, one of them leaves her their number, and she has no idea what to do about it, having very little actual experience with romance. Mostly harmless and often ineffectual, though she can in fact use a sword if she has to.
