Also known as: ゴットゥーザ様
A character from Lucky Star. Animated representation of Gotou Yuuko, who is in real life (and in quite the contrast to the cute and innocent types she often voice-acts) both an avid biker and proponent of the biker lifestyle.
The name came from ゴトゥーザ様 (Gotouza-sama), Gotou Yuuko's real nickname given by Sugita Tomokazu. In other words, Gottouza is voiced by Gotouza-sama.
Gottouza will destroy you, so don't cross her.
