("There's no way a guy with that personality could be the bottom!!" - by Nyapon) Since she once had a yuri doujinshi drawn of herself as the 'bottom' in the past, she has a bit of a complex about yuri. Apparently, she can't even handle wholesome yuri. Appearance: Has cat ears. Wears a ribbon on her head. Has cherry blossom-shaped piercings in her cat ears.
