Hurricane Polymar

Yoroi Takeshi works as an assistant to detective wannabe Kuruma Jo in a small, struggling private investigation service based in their rundown office. The office's precarious financial situation is often threatened by Nanba Teru, whose father owns the building, as Jo is frequently months behind on rent. Unbeknownst to Jo and Teru, Takeshi has a secret: he's the son of the International Police Department Chief, and when danger arises, he transforms into the superhero "Hurricane" Polymer using his Poly-Met helmet, which grants him incredible strength and fighting abilities.
