HENTAI KAMEN: THE ABNORMAL CRISIS

Just to bring you up to speed. Student Kyosuke Shikijo was madly
in love with the adorable Aiko. Unfortunately his boundless timidity
and his obsession with female underwear got him no further than
sniffing her panties. But his perversion had a remarkable side effect.
It transformed him into superhero Hentaï Kamen who, of course,
had to save the world from an evil monster. Aiko’s heart, however,
remained closed for him. Four years later we find our hero in rehab,
avoiding panties like the plague to be worthy of Aiko. And then a
new threat emerges. Dynoson, a mutation between a crab and a
vacuum cleaner, has the power to suck up all the panties in the world.
If Kyosuke wants to save humanity again, he’ll have to stop being
holier than thou and plunge his nostrils in smelly strings again…
that is if he can still find one!
In 2013 director Yûchi Fukuda succeeded in adapting Keishu Ando’s
delirious manga into an instant culthit. Hentai Kamen: Forbidden Super
Hero managed to pull off the impossible by turning a pervert into
a hero. Hentai Kamen: The Abnormal Crisis sees Fukuda and his lead
actor Ryohei Suzuki breaking through the frontiers of comic insanity.
A warning to our female audience. After this superhero parody, their
underwear will never be safe again!
