Hapless Akira Gunji somehow finds himself on what can only be called a date with one of the AMO's most wanted aliens, Raika Nadeshiko! But Akira's partner, Sho, has been tasked with eliminating Raika-and he's dead set on carrying out his mission! When Sho crashes the date with an attack out of the blue, Akira throws up a shield to protect Raika. Still...can he really believe a fugitive's claims of innocence?

The pair manage to flee the scene and escape Sho, but once another Raika shows up, a hyper-dimensional battle between aliens is about to unfold!
