―Gamninjustri, a place where all manner of ninjas gather―

As the struggle for control increased between the Daimyos of the nations,
tensions rose between the two great nations,
each of which was home to one of the major schools of martial arts.

The Compa Style which has mastered the Ninja Arts based on the Command Technique.
The Honeypa Style which has mastered the Ninja Arts rooted in the Action Technique.
The two camps were stuck in a ruthless competition of skill in order to achieve hegemony,
but as they fought on, a mysterious army of mechanical ninjas made their assault.

The mechanical ninja army overran the smaller nations in an instant,
and its leader, Yoh Gamer, made an announcement to the world.

The "Super NINJA War" to decide
the world's strongest school is about to begin!


A warring world full of powerful rivals, where several nations,
large and small, compete with one another for supremacy.
Native yokai have also been known to roam in the wilderness in these nations.
Each nation deploys ninjas onto the battlefield as its main fighting force.

The Two Great Nations

There are two great powers within Gamninjustri.
The allied nations known as Heartland which is home to the Compa Style Ninjas.
The great nation called Marveland which is home to the Honeypa Style Shinobi.
