HIRO the savior of Yomikawa the year was 3040 in an apocalyptic Japan when the Emperor and Shoguns were re-established. There was a ruthless feudal lord who only had one child who would inherit all his title and fame, but was cursed by a sorcerer to change into a mechanical wooden toy if the Seven Obstacles were not met. These Seven Responsibilities were handed upon HIRO as a punishment for his father, and they act as both a challenge to establish his worth to the Kingdom and a curse he must overcome before his time runs out. HIRO sets out with a motley crew of young and wild individuals to complete each job before he turns into firewood and the Kingdom of Yomikawa is destroyed.
