HK: Forbidden Super Hero 2013

Kyosuke Shikijo Ryohei Suzuki is a timid young man with a strong sense of justice, the son of a dominatrix and a detective. He joins the school’s martial arts club to toughen up while staying true to his values.

Aiko Himeno Yoshiko Sengen is the newest girl in his class and also the club’s manager. Kyosuke is drawn to her from their first meeting, and his hope for a real connection grows as he trains and observes her leadership.

When Aiko is caught in a bank-hostage crisis, Kyosuke hatches a daring plan to intervene. He infiltrates the scene by pretending to be one of the criminals, but instead of a proper mask, he ends up with a pair of women’s panties on his face, a comic misstep that triggers his unlikely transformation into Hentai Kamen.

As Hentai Kamen, he fights criminals and earns praise from the city—along with the admiration of Aiko—in a way that blends bold action with offbeat humor.

A new threat emerges when Tamao Oogane [Tsuyoshi Muro], the leader of a rival group, believes there is treasure beneath the campus and has bought the school grounds. After a humiliating clash with Hentai Kamen, the thugs unleash a series of assassins to finish the masked hero, including a robot embodying a severe school code of conduct—Very Serious Mask [Jiro Sato].

The last assassin is Bizarro Hentai Kamen [Ken Yasuda], who masquerades as the new school teacher. Kyosuke soon learns that Bizarro HK’s perversity dwarfs his own and starts to doubt whether his powers can hold up under this doubled threat.

Tamao captures Kyosuke and attempts to shoot him, but a spark of memory about his late father gives him a second wind. He transforms again and defeats Tamao in the ensuing struggle.

The final duel pits Hentai Kamen against Bizarro HK. Hentai Kamen triumphs, but his mask is too damaged to hide his face, and Aiko finally discovers his secret identity. Just as the two share a quiet, romantic moment, Tamao bursts onto the scene in a giant robot. Kyosuke, lacking his usual panties, borrows Aiko’s instead, and with a bold strike to the robot’s crotch, sends it exploding.
