This is tokusatsu distilled to pure adrenaline. A bike, a suit, a demon to fight, and nothing wasted on why any of it matters. The animation moves like someone finally figured out how to make a Metal Heroes suit sing in motion, and it does, and then it's over.

Hikaru seems like just another student, but he is really a hero who protects Earth from demons, backed by a battle suit and a powerful motorcycle named Sparon. After transferring to a new private school, he clashes with Gomi, a violent bully whose father is the most influential man in town. Hikaru is secretly a trained Campus Special Investigator, sent to look into a string of student suicides at the school, and something darker than bullying appears to be at work. The single-episode action OVA draws its inspiration from the Space Sheriff tokusatsu heroes Gavan and Sharivan.
