Uh, okay. This needs remedying.

Alexis von Ventus:

Date of Birth: 7 June 1995
Life: 1000

The sister of the castle's master, and an antagonist. Her first appearance was in version 3a of Lunar Shadow. She is referred to as "the dreaming lass".

Appearance:
She has shoulder-length brown hair and blue eyes. Her skin is white.
She wears a sleeveless blue top underneath a lavender-purple corset. She wears a sky blue sleeveless coat of some kind over that; it almost reaches her ankles.
She also wears blue jeans and light blue tights with blue pumps. She wears yellow rubber gloves on her hands and blue armbands over her elbows.
She finishes her outfit with a straw hat. She is not to be associated with "Straw Hat" Monkey D. Luffy from the One Piece anime.

The appearance description would match Vresun Gym Leader Alexis, though with the sprites Cave Story uses, it'd be a bit hard to be 100% accurate.
