Today, it was announced and hinted that the anime that will pierce the heavens, Tengen Toppa Gurren Lagann, will be returning. In a tweet (shown at the bottom) from the Team Gurren project, it leads you to a site that has the following image.
The direct translation of the text merely says “Tengen Toppa Gurren Lagann Restart.” Other than the facebook and twitter links, not much else is there. Therefore, currently it is unknown as to whether or not this is a reboot, restart, or an alternate reality. But what we do know, is that Gurren Lagann is coming back!
