Getsu Fuuma Den

In 14672 A.D., the first year of the Demon Age (魔暦元年 Mareki Gan-nen?), the demon lord Ryūkotsuki (龍骨鬼?) escaped from hell and plotted to conquer the surface world ruled by the three Getsu brothers (月氏三兄弟 Getsu-shi San Kyōdai?). The Getsu brothers fought against Ryūkotsuki, each wielding one of the three spiritual Pulse Blades (波動剣 Hadōken?) that have been passed within the clan for generations. However, the brothers were ultimately defeated by the demon and only Fūma (風魔?), the youngest of the three, survived. Vowing to avenge his slain brothers, Fūma ventures into Kyōki-tō (狂鬼島 Mad Demon Island?) to recover the three stolen Pulse Blades and summon the spirits of his brothers to defeat Ryūkotsuki.
