Assigned by your boss to eliminate the monsters in the old polluted building in the city of Fushi, forcing you to get involved in this monster case.

As a monster buster, you will definitely accept your boss's duties with grace.

"Hey!!! Watch out! Don't come near me! I can beat you to death!!"

The first thing you hear, the scream of an grumpy child. When you peek, you see the figure of a child cornered by a large monster in front of him.

He was afraid, but had to be brave.
