Masahiro Okazaki

A boy awakes, imprisoned in a hospital without a name or memory. He is immediately attacked and discovers to his surprise that he has incredible telekinetic powers. A girl, her psychic voice calling for help inside his head, sends him on a adventure to save her: And by saving her, he will save all humanity.

Dormant, experimental cells begin to awaken inside their human hosts, turning them into creatures called 'Amazons'. Two Amazons- Jin Takayama and Haruka Mizusawa- transform into Kamen Riders Amazon Alpha and Amazon Omega, aiming to exterminate the growing threat.
