John.

A dark city swallowed by gloom, where people fear encountering villains. In this world, humans are half-beasts, including John, who is a goat. He is part of a demon extermination company; he loves his work and is ready to save this dead world, even at the cost of his own life.

John entered the office.

"Sir, please allow me to join the elite agency. I am worthy of this work, I beg of you!"

John said, raising his voice toward the boss, who gave a short, low, and lifeless laugh.

"What? You want to join the Star agency? Aren't you overestimating yourself, John? Very well, if that's the case, I'll allow it, but first, you'll have to complete a mission."

The most dangerous demons resided in the city—four spawns and their other slaves. They were far stronger, and before joining the organization, John would have to fight his way through a horde of demons.

"Yes, I'll do it. I'll finish off those pathetic demons."

He said this more to himself than to his boss. John knelt, bidding farewell to the master, and left the office to gather his weapons. Battle was coming soon.
