Otoko Strike  

Strike Man, ストライク男

Strikeman is an individual who dresses up as a superhero and uses baseballs and related items to punish offenders such as public drunks, flashers, and parking violators. He has gained attention from Bokuto Precinct due to his actions, earning him the title of a major nuisance and a complete loon. Strikeman seems to have an obsession with Natsumi, referring to her both as his nemesis and sidekick while calling her "Home-Run Girl." Despite many attempts to capture him, Strikeman manages to escape due to the fastball pitches he uses as weapons. He utilizes a Harley-Davidson Softail motorbike for transportation, which is designated FLSTF. During Full Throttle's first season, Nakajima was suspected by his colleagues of being Strikeman due to some events and a similar appearance, but it was later proven that he was not the case.
