Gurren Lagann is a story that portrays the lives of several girls attending a Japanese high school named Teppelin with a very loose sense of humor. The setting is mainly based on the city of Kasukabe in Saitama Prefecture. The main character is Simon, a skilled digger from the Giha village who, despite these attributes, is not in a sports club and has low grades. His laziness at school is due to her love for digging and lack of interest in anything else. The serialization began with the four main characters in their first year of high school: Simon, Kamina, Yoko, and Leeron. As the story progresses, they move on to their second and third years. Gurren Lagann is a light-hearted slice of life comedy which, like most shows of this genre, does not have an ongoing plot and typically focuses on the daily lives of the characters.
