[1] The OVA is a one-shot tribute to the Metal Hero genre of live-action superhero shows that were prevalent in the 80s and 90s,[1] specifically to the Space Sheriff trilogy of Gavan, Sharivan and Shaider.

17 year old student Hikaru Shihoudo is Hikaruon, a metal-clad super hero fighting the forces of the evil organization known as Uraer.

On the surface, what he sees is a case of unhappy students in a school where money and status rule all; but Hikaru cannot accept things for what they seem to be, and he soon finds himself on the trail of an evil so powerful that it could not have been derived from this dimension.

Now, he must learn how this mastermind is controlling all of the unfortunate happenings at school, and stop him from taking more innocent lives for his own selfish pleasure.

Disguised as a transfer student, he must investigate the strange suicides in town alongside Azumi Hazuki, his 22 year old home room teacher.
