Tengen Toppa Gurren Lagann: The Gurren High School

Tengen Toppa Gurren Lagann: Gurren Gakuen-Hen (Gurren School Edition) manga that re-imagines cast of TTGL Robot Mecha in a parallel world, at a high school. The people are the same, situations are a bit different with more Ecchi-ness and fanservice for male and female readers. This more or less pokes fun at not only the Anime in general, but also many school based Mangas.
