Tengen Toppa Gurren Lagann - Rasen Shounentan

Written by Mia on Earth, where the barrier surrounds them, this land is the only "world", which they know. Once, when part of the barrier is broken, Simon becomes a witness to what no one else has seen. Starry sky with unknown light. When he is trying to explain what he saw, no one believes. When he ceases to try to convince everyone that he saw was true, he meets a girl who comes out of the head of the wick. Where did this girl come from and what did she need from Simon?
