## Description
This is not a story of heroes.

Since time immemorial, warriors called musha have ruled the battlefield, granted supernatural power by their enchanted suits of armor - tsurugi.

Minato Kageaki is one such musha, driven by duty to don his crimson armor and challenge the greatest evils of an age. But though madmen and tyrants fall to his blade, never will he claim that his battle is right.

For the tsurugi he wields is cursed Muramasa, which five centuries ago brought ruin to the land, and innocent blood is the price it demands in exchange for its terrible might.

"Where there are demons, I slay them. Where there are saints, I slay them."

These words are an oath, the unbreakable Law binding him to his armor. But they also tell the story of his past, and of the future to come.

### Saya (沙耶)
A mysterious girl who appeared before Fuminori, sparking intrigue with her quest to find her missing father. In Fuminori's distorted perception, Saya is the only figure of normalcy and becomes a crucial source of mental support. As time passes, she gradually grows fond of Fuminori, reciprocating his deep affection and care towards her.

[spoiler]True to Fuminori's suspicion, Saya is not a human; she's an eldritch entity whose actual form is perceived as grotesque and horrifying to everyone except Fuminori. 

Her origins are ambiguous and subject to various interpretations throughout the story. The narrative suggests that she is not of this world, either literally or metaphorically. She has no memories of where she came from and is guided only by her instincts. Her relationship with Fuminori strongly influences her behavior, and she takes actions driven by her desire to be with him and understand his world.

Saya usually hides in the shadows and preys on creatures of all sizes, from cats to human beings, typically killing them by snapping their necks or disembowelment through some unknown means and then feasting on their internal organs. [/spoiler]
