Yuuki is targeted by a Zodiarts who is obsessed with her. Meanwhile, the locker which attaches the Rabbit Hatch to the school goes missing leaving Kengo trapped on the moon.

The Pyxis Zodiarts decides the only way to get revenge is to use his power to kill all the girls who rejected him, including Miu, by driving a bus with them all inside off of a bridge. Meanwhile, Kengo is still trapped in the rabbit Hatch.

Gentaro, Yuki, Kengo, Tomoko, Ryusei, the student council president Sugiura, the former Pyxis Zodiarts Hiroki Makise, and transfer student Erin Suda are chosen for an astronaut test in a closed environment and endurance test, but Kengo's weak constitution and the arrival of the Aquarius Zodiarts cause trouble for the group.
