It takes various liberties with the original story to better suit the post setting and introduces anime and modern styled designs.

The game follows seven samurai as they fight off an immense army of mutants, cyborgs and other inhuman creatures in an attempt to bring about a regime of peace for those in need.

When the humanoids and various Agents of the city set out to retrieve her and her Sacred Jewel, the villagers quickly find themselves in danger and look for Samurai (known in the game as "hunters") to protect them.

The main point of the game is to constantly utilize the second sword which is carried in the protagonist's sheath, allowing the player to achieve a larger combo score.

It permits the protagonist to use a second blade for a limited amount of time to increase attack power and range of the weapons.

A Just Guard allows the player to deflect an enemy's attack with skillfully timed uses of the triangle button.

Zex's massive strength causes the ground to collapse, and Natoe finds himself in an underground city called the "Town of Warriors".

He saves the female humanoid Cue in the process, offering to help her find her lost memories in return for her assistance.

[12] The village safe for the time being, however, the "Man In White" informs them that the city no longer need the sacred child and that Jodie has been kidnapped by the humanoids.
