Kazuki wakes in his original world, adjusting to normal life but missing his friends. In this reality, Rara and Ken collaborate on parallel world research. As barriers between worlds weaken, robots appear, wreaking havoc. Determined to end the war and seal the rift, Kazuki and Mitsuki return to the parallel world, only to find Mitsuki was captured by Rara after arriving earlier, setting the stage for a critical confrontation.
Kazuki experiences hallucinations of fighting robots that no one else can see, so he should have expected trouble when the most beautiful girl in school took an interest! But there's no way he could have expected to be waylaid by a mad scientist and thrown into a parallel world with robots, aliens, and a boarding house filled with beautiful girls! He may not make it home. He may get hurt. He may go insane. But at least he gets to drive the Robots!
