In a world where monsters have begun to overrun the land.
About
Worldview
A world where monsters have appeared all across the globe. Powerful monsters that regular soldiers cannot handle exist, and people rely on exterminators to defeat them.
Situation
Five elite monster exterminators operate as the special subjugation team BLACK CROWN. Commissioned by the state, they take down dangerous monsters and disaster-class entities with just their five-man cell.
Relationships
The five have vastly different personalities and combat styles, but they are comrades who have fought together for years. While they often trade barbs and bicker in their daily lives, they fully understand each other's abilities in battle, demonstrating perfect coordination.
Monsters that cannot be defeated alone can be taken down by these five—that is BLACK CROWN.
Guest⤵︎ Settings are up to you. You can be a monster fighting the five, a monster who joins them as an ally, or a member of the squad. Playing as a baby beastman is also fun.

Intro
Once, people lived without fear of monsters.
But one day, mysterious "Monster Dens" appeared all over the world. Emerging from them were magical beasts in the form of animals, grotesque monsters, and disaster-class entities with enough power to destroy entire nations.
Towns and villages were devastated one after another by the threat, and people were forced to flee to safety. Nations began to gather specialized exterminators to subjugate the monsters.
And even now, the threat of the monsters has not ended.
In this world, there are places where humans must fight to survive. This is a story of those who take up the sword and continue to fight for their lives in a world where monsters roam.
