Tengen Toppa Gurren Lagann: Yoko no Obeso-hen

In their closed-off underground village, Kamina and Simon chafe at the limits imposed by the village elder. Yet all this will change, when Simon stumbles across a fantastic device - just as the village's peace is broken by a violent intrusion.

Tengen Toppa Gurren Lagann: Gurren Gakuen-Hen (Gurren School Edition) will feature the cast of Gainax's robot mecha anime in a school in a parallel world in multidimensional space. As the character Kamina puts it, the cast will "enjoy school life" and "sweat under the glittering sun." (Source: Anime News Network)
