A nebbish father and schoolteacher finds the courage to face both his personal issues and a horde of invading aliens after assuming the guise of an unpopular television superhero in maverick Japanese director Takashi Miike's warmhearted comedy. Nice guy Shinichi (Sho Aikawa) just can't seem to find the respect he so readily deserves -- he's cuckolded at home, his son is constantly harassed by bullies, and his teenage daughter is always willing to sell her body to the highest bidder. In order to escape from his depressive reality, Shinichi frequently slips into his private room and dons his patchwork Zebraman costume. As a child Shinichi loved Zebraman, and despite the fact that only six episodes of the series ever aired, the nobility of the character has stuck with Shinichi well into adulthood. One night, while Shinichi is prowling the streets in his Zebraman costume, he comes across the frightful Crabman -- a perverted villain with a crab head and a dangerous pair of scissors. Already in character, Shinichi acts on his Zebraman instincts and effectively employs the Zebraman back kick. Later, Shinichi strikes up a friendship with handicapped transfer student and fellow Zebraman fan Asano, and begins to develop feelings for the boy's pretty and kindhearted mother. Suspecting that an alien takeover may be at hand when a horde of squishy extraterrestrial invaders begin possessing the locals and claiming the lives of young girls, the fledgling superhero leaps into action. While at first Shinichi bumbles in his attempts to keep the town safe from these strange beings, it doesn't take long for him to develop the confidence that will allow him to truly take on the persona of his childhood hero and fully realize his Zebraman powers.
