Un chico llamado Kenny Blackwood llega a Tokio para pasar el verano con su padre. Todo parece indicar que serán unas vacaciones comunes y corrientes. Sin embargo, muy pronto se ve envuelto en una peligrosa e inesperada misión que pondrá a prueba su valor e inteligencia. Este joven héroe descubre que posee poderes especiales y que a su alrededor hay seres mitológicos que inciden en los acontecimientos cotidianos. Kenny deberá encontrar la legendaria Espada de Cielo, la cual le servirá para salvar su vida y evitar una guerra. Con esta arma enfrentará a un conjunto de terroríficas criaturas que no dudarán en matarlo si él les da la oportunidad. Su única ayuda será Kiyomi, una sarcástica y ruda chica.

Three treasures. Two friends. One destiny.
Ever since Kenny learned that he'd been chosen as bearer of a magical sword, he and best friend Kiyomi have been protecting the human world from ancient Japanese monsters. But Kiyomi's human soul has been taken from her and only the restoration of the three sacred treasures - the sword, the mirror and the jewel - can save her from transforming into a monster herself.
Yet as they complete their mission, they discover that all their actions have been manipulated and an undead army is about to be unleashed upon humankind. The forces of life, with Kenny as their champion, gather their allies for a final showdown.
