As thick, ashy smoke envelopes the city, Invader refugees band together to try and survive human attacks. The government sends out giant yellow machines to exterminate the Invaders. The group is going on a trip to investigate aliens by the ocean, and they celebrate Ouran's birthday at Futaba's house. Futaba also receives a mysterious package in the mail from the leader of the anti-violence group. The YUF confronts Futaba's group and argues about the rights of violence towards invaders.
