Meanwhile, Kirara has escaped from the enemy and wanders about in the nest where she encounters the Kiseichuu princess, Chacha. Chacha has been locked away deep in the nest due to a mutation causing her to be different than the other Kiseichuu. Chacha wants to stop the Kiseichuu from destroying humanity, and plots to escape the nest with Kirara. Retto and the team arrive at the nest and defeat the Kiseichuu one by one.
