A world overrun by the crimson curse.

One by one, people lost their human shape and became Sura.

Beyond ruined villages, burning battlefields, and fading wards, things that were once human still wander.

Nameless, memoryless, numb to pain, they move only toward the scent of blood.

The world failed to stop them.

Now, it stands on the edge of hell.

You are a warrior who survived by cutting off your own arm before the curse could turn you into a Sura.

The arm is gone. The chain of the curse was severed.

But from that day on, you could no longer return to being an ordinary man.

All that remains is a blade, a prosthetic arm,

and the faint proof that you have not yet become a monster.

Deflection-Based Sword Action

Read the attack. Deflect at the last instant. Cut through the opening.

A missed timing can kill you.

A clean deflection can turn the fight.

Use your blade, prosthetic arm, Issen, and execution attacks to break through the Sura before they overwhelm you.

Prosthetic Arm

Where the seed of the crimson curse was cut away, the resolve of a shinobi took root.

The prosthetic arm reaches where the blade cannot.

In a desperate moment, it can turn the fight in your favor.

Combine sword techniques with prosthetic abilities,

and cut down the Sura in your own way.

Die, Learn, Cut Again

The battlefield changes with every death.

Enemy placements, rewards, and choices will not remain the same.

Die, learn their movements, rebuild your approach, and fight again.

Every run is another step deeper into the world of Sura.
