Strike, Otoko

ストライク男

Strikeman, a costumed vigilante who refers to himself as a superhero, employs baseballs and related equipment to punish offenders, including public drunks, flashers, and parking violators. He has drawn the attention of Bokuto Precinct on multiple occasions, gaining notoriety as a significant nuisance and a complete loon. He appears to have a fixation on Natsumi, viewing her as both his nemesis and his sidekick while addressing her as "Home-Run Girl."
As of Full Throttle, there has been no clue regarding Strikeman's identity. During the first season, Nakajima was suspected by his colleagues of being Strikeman due to certain events and a very similar appearance, but this was found to be untrue.
Many attempts have been made to apprehend him, but Strikeman escapes using the various fastball pitches he employs as weapons. When he attempts to enact "proper justice" on an offender's property, such as their cars, Strikeman uses baseballs fitted with sharp spikes; he has, in fact, used them against Miyuki and Saori as a distraction. He rides a Harley-Davidson Softail motorbike, designated FLSTF.
