Gotouza is a hyper-masculine bōsōzoku-style (Japanese motorcycle gang-style) caricature of Yūko Gotō that appeared as a guest in Lucky Channel after Minoru destroyed the set in a fit of rage. She acted as a mediator between Minoru and Akira and tried to convince them to patch things up by force. She rides a motorcycle which is a direct parody of the real Yūko being a devotee of the biker culture. When she leaves Lucky Channel in her motorcycle she makes the classic siren sound of the bōsōzoku depicted in anime and other media. But as she has no siren, she makes the sound herself.
Like Nanako Kuroi, she has a sharp tooth protruding from one corner of her mouth, it can be seen when she got on the motorcycle.
The name of Gotouza comes from the fact that she likes The Fist of the North Star/Hokuto no Ken/北斗の拳. The nickname is derived from the name Souther/Sauzaa/サウザー, one of the main antagonist of the first part of that famous manga. Tomokazu Sugita, the voice actor of Kyon in The Melancholy of Haruhi Suzumiya, gave her that nickname upon discovering this. Also, the motorcycle shown during her appearance in Lucky Star is her own motorcycle.
