Continuing to the Gunmen rallying point, Team Gurren finds themselves on a strange hot springs getaway.

Trying to do her part in Team Dai-Gurren, Nia decides to become a cook, but just before the crew have a taste of her dishes, Cytomander, the fourth member of the Divine Generals, launches an aerial attack on the Dai-Gurren. Simon leads the counter-attack on the Gurren-Lagann, this time accompanied by Yoko, who replaces a sick Rossiu.

The members of Team Dai-Gurren make their preparations for the imminent war against the Anti-Spirals, but Rossiu is missing. However, when Kinon tells Simon about what he really intends to do, both start to look desperately for him.
