Players take on the role of Hiro and Futo as they embark on a quest to save the world from an ancient samurai warlord's demonic army. The demon warlord has transformed innocent animals into fearsome warriors, causing chaos and destruction throughout the land. As a ninja master, it is up to Hiro and his friend Futo to restore balance to nature and defeat the demons.
Gameplay involves controlling Hiro and Futo through various worlds, using a third-person perspective with some freedom to explore. When lost, players can meditate to receive a hint and see an arrow pointing in the direction of the next objective. As players progress, they will free four other ninjas who will become playable characters.
Each character has unique abilities, such as Hiro's Kuji spells or Futo's large hammer. Characters can switch between each other at any time and have basic attacks, defence breakers, and sneak modes to aid in combat. Players can also gather fruit to restore health and collect items to mix into potions, bombs, and power-ups.
