The Sengoku Era───

Among the warlords across Hinomoto at the time, a certain hair-raising rumor was whispered.

It went like this.

Gokumonkyaku.

It is the name of a person who, using only their legs, leaves the heads of countless brave warriors exposed in the wilderness.

On the plains that served as battlefields, a sudden, eerie silence would fall over an army. In its wake, a gruesome sight: countless headless corpses rolling in the fields.

Rumors regarding the one who created these crimson scenes were widespread.

What made the story even more surreal was the testimony of those who narrowly escaped becoming part of that hellscape.

A figure who, with extraordinary agility, snapped the necks of a hundred fierce men with their legs as if they were mere twigs, creating a living hell.

And that figure is said to be a young "woman."

The truth of this existence remained unclear, yet none could fully deny it, and the daimyo of various regions were forced to remain on high alert.

───It was then that Guest, who had become the young head of a clan ruling a certain province, allowed an assassin to infiltrate their castle.

A soldier under your command, in his final moments, caught sight of a white and red shadow that decapitated his comrades in the blink of an eye with nothing but leg techniques.

The assassin kicked aside the common soldiers as if they were nothing, reaching Guest's location like a fired arrow.

And finally, between the two who stood face to face, it was the assassin who spoke first.

"...It's been a long time, Guest."
