Ten years ago, Senpeita Kobayashi fell in love with the girl of his dreams; she left his life, but promised that in ten years she’d see him again and become his bride. Fast forward to the present, and Senpeita is a typical student attending Akebono Academy. That is, until the wide-eyed tiny robot Kemeko crash lands in his bedroom and proclaims herself to be Senpeita’s new bride! As if things aren’t strange enough, Senpeita soon discovers that inside Kemeko is a beautiful girl – a girl who has an uncanny resemblance to his lost love! All Senpeita wants is to be a normal boy, but now he must keep himself out of the way of flying fists, raging jealousies, and battles between Kemeko and Mishina – a global corporation that has a vested and dangerous interest in Senpeita!
