Episode 21

After Nia appears to Simon, Yoko comes and drives her off. It then goes into a flash back about what Yoko has been doing for the last year.

It shows a young boy called Nakim getting tormented by some other kids and he gets pushed down. A girl tries to help him up but Yoko comes by and says he should get up on his own, which he does. Yoko then gets introduced as the teacher at that school, and she is going by the name Yomako.

Her students love her and she is a great teacher. One day Nakim who was getting bullied notices that Yomako shares a striking resemblance to Yoko, but she quickly silences him under the grounds that there is no talking in. Later his back pack(who once belonged to his father) is thrown into a very tall tree and he climbs it to get it, but he can't get down. So Yoko climbs the tree to talk to him and she gets him down. Then they get the order to evacuate to an underground town. Everyone is there except one girl, who was at the light house.

2 beastmen with their Gunmen kidnap the girl and tell the people to give them all their food. Yoko quickly dispatches the beastmen with her rifle, revealing the fact that she is Yoko to everyone else. She then goes to Kamina City.

It then returns to current time, and she frees Simon, who then frees Viral. They get out of jail, and Kittan returns the core drill to Simon. Simon then extends an offer to Viral to pilot Gurren. He accepts and all the Gurren Brigade blast off into space to help Rossiu. The episode ends with Viral and Simon saying Kamina's signature catch phrase.
