Zebraman awakens fifteen years in the future, unclear on what has happened to him, and quickly discovers that the evil Zebra Queen has a hold on Tokyo.

Straight from the delightfully-bent psyche of Takashi Miike (Ichi the Killer, Audition) comes a scandalous tale of good vs. evil. The year is 2025. Tokyo has fallen, and the world cries out for a hero. It cries for Zebraman. This striped crime fighter is the only hope for those who live in fear of the Zebra Queen, a hooved seductress out to conquer the world with the aide of her Miniskirt Zebra Police. The Queen has stolen Zebraman's powers and instituted Zebra Time: ten horrifying minutes each day when murder is legal. Without his super strength, Zebraman is just a guy with a mane - a broken-down hero unable to stop the onslaught of evil. Before he can take a bite out of the bad guys, Zebraman must find the young girl who holds the secret to regaining his ass-kicking powers and prove, once and for all, that a hero never changes his stripes.—Amazon

School teacher Ichikawa (Sho Aikawa), sometimes known as Zebraman, suddenly awakes 15 years later in the year 2025. The megapolis known as Tokyo has now been renamed to Zebra City. The city has become virtually crime free due to a new measure known as "Zebra Time." Every morning and evening for five minutes "Zebra Time" is implemented, which allows the Zebra Police to eliminate any potential criminals. Soon enough, Ichikawa comes under attack by the Zebra Police, but is saved by Ichiba (Naoki Tanaka) and taken away to a safe haven known as the "White Horse House". At the "White Horse House," survivors of "Zebra Time" recover from their wounds, while plotting methods to overthrow the city's govenor who implemented "Zebra Time". Throughout all of this, Ichikawa has lost his memory and cannot remember his past as Zebraman .—AsianWiki
