The story takes place in Japan, you play as Hayate, a young up and coming ninja warrior out to stop the evil of Lougi and his army of ghouls and goblins. You are out to avenge your father's death as well as the emperor and rescue your girlfriend from the clutches of evil and bring an end to the terror visited upon your lands.
Some of the villians you face are Marco Killmore (a half man, half eagle samurai warrior), Zallen (a disgraced samurai warrior out to destroy Hayate), Vengor (a stone shiva-type character), Desfal (a medusa-like woman), Destroyer MPK (a possessed collection of samurai armor) and of course the evil samurai knight himself, Lougi.
