Summary
One of the seven heroes of the Fire Clan who fought in the great war a thousand years ago.
Known as the "Fireball Kid of Naniwa." He is a warrior of the Fire Clan, but does not carry the blood of the Fire Clan. He was just a normal boy from the village with no special abilities and a small stature. His village was burned down by the Root Clan, which fueled him with a strong desire for revenge and led him to throw himself into battle. He was gravely injured on the battlefield and wandered the edge of life and death, but was resurrected as a warrior with a fully weaponized mechanical body thanks to the technology of the people of Ihika.
Now, he exists as a spirit residing in the "Holy Sword·Toriidō Saburō" he created herself. "Toriidō" is the place where Saburō forged her holy sword.
