What Is HK: Forbidden Super Hero About?
The premise of HK: Forbidden Super Hero in 279 words, with nothing given away. The full story follows below.
In a bustling Japanese city where everyday life brushes against the bizarre, a fresh wave of off‑beat heroics emerges from the most unexpected places. The film blends bright‑light comedy with kinetic martial‑arts action, treating the absurd as a natural part of the urban rhythm. Its tone leans heavily on playful subversion, inviting the audience to laugh at conventions while still feeling the pulse of a classic underdog story.
Kyosuke Shikijo is a talented martial artist whose strong sense of justice was inherited from his late detective father. Though he appears modest and even a bit timid, he carries a secret that turns his ordinary life into something wildly extraordinary: by donning women’s underwear—a quirky inheritance from his parents’ own unconventional tastes—he transforms into the bizarrely powerful alter ego known as Hentai Kamen. This odd ritual grants him superhuman abilities, allowing him to channel his fighting skill into a flamboyant, if unconventional, brand of vigilantism that both amuses and baffles those around him.
Kyosuke’s world is further brightened by the arrival of Aiko Himeno, the new manager of his martial‑arts club and the object of his instant affection. Their dynamic crackles with youthful energy, as Kyosuke’s earnest desire to protect her collides with the unconventional means of his heroics. The relationship hints at a deeper bond that fuels his courage, while the school setting provides a backdrop where everyday pressures and eccentric personalities swirl together.
Against this backdrop of playful absurdity and heartfelt ambition, the film teases a clash of ideals and identities. The city’s ordinary rhythms are poised to intersect with Kyosuke’s out‑of‑the‑ordinary powers, promising a story where humor, heart, and high‑octane action converge in a delightfully unpredictable dance.

Spoilers ahead
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.
