Tengai Makyou Zero

In the feudal Japan-like world of Jipang, an evil prince releases the demon lord Ninigi, who in turn seals the gods of Jipang and suppresses the people of six kingdoms with his demon henchmen. After one of the henchmen attack his village and slay his grandfather, the main character, Higan, learns he is the legendary "Fire Hero" and must set off to save the kingdoms. Along the way, Higan meets several characters, such as Subaru, a fairy and Tenjin, a swordsman.
