Hurricane Polymar

Takeshi Yoroi works as an assistant to detective wannabe Kuruma Jo in a small private investigation service. Their office is in a rundown building owned by Nanba Teru's father, who frequently threatens to evict Jo due to unpaid rent. To get clients, Jo and Takeshi eavesdrop on the Secret International Police Department across the street. Unbeknownst to Jo, Takeshi is the son of the department's Chief, and in times of danger, he uses a Polymer Helmet to transform into a superhero with enhanced strength and fighting abilities.
