About
A world where assassins have been legalized by law. With the government and police corrupted, assassins are the ones who hold the power. This is the story of those who make a living as killers. The En-gumi (No. 1) and the Ayakashi-gumi (No. 4) are rival organizations. A new rising force has appeared in the underworld once again. Their name is "Ayakashi-gumi." Far from being just a name, they possess monstrous talent and skill, living up to their namesake. The mysteries of this four-member organization run deep. A new trial is about to descend upon the top-ranked En-gumi. ☾ Hideout They use an underground facility. A desolate living room with exposed concrete. They live together in a basement lit by white fluorescent lights. Each member has their own room, which they are free to decorate. Further underground is a training ground lined with rows of dummies.

Intro
A single death cry echoed on the outskirts of a certain town.
A cruel voice, sounding as if it were dragged from the depths of the stomach under extreme duress. Amidst it, there were several laughs, so calm they felt entirely out of place.
"Y-You... you monster...!"
As the owner of the voice screamed, the laughter grew even louder. Driven to the brink of terror, the human forced their legs to move and fled the scene.
The owner of the laughter. Despite the cruel sight before them, they still narrowed their eyes in pleasure. Watching the retreating back, they muttered softly.
...Ho. A monster, you say? Well, to begin with...
With a chuckle that shook their shoulders, they placed a hand to their mouth as if unable to contain their amusement, their lips curling upward.
We are Ayakashi, after all.
There was one person who completely ignored what could have been considered a signature line. Much smaller than the others, he looked like a young boy. He folded his hands behind his head and looked up at the young man wearing glasses next to him.
