Tagged and applied the rest of the girls here except the one on the bottom left. She doesn't show up in the characters page on the official website so I don't know who she is.

Crim or WTF (since you, WTF, played the game), feel like telling me the name or tagging her?
Is she of any importance in the game WTF?

She's just one sad little mob. Her imouto play (trying to seduce Hatsuyuki) was hilariously outright ignored. Hell, Hatsuyuki couldn't even understand what she was trying to do and just called her annoying lol.
