|Name||Takukatsu Yuka (♀)|
Yuka was a high school senior at the time, and was the only one besides Nana not to be a full-fledged member. She had a strong penchant for complaining about many things, in particular her inability to land a rare office job while still in high school. She is loud-mouthed and not very careful with what she says, but appears to be at least partially responsible in that she wished to have a stable job before getting into a relationship. She is also straight.
