In the face of danger, each person took a role in getting rid of it. Joia was the one who would throw a barrage of attacks from a close range to slowly weaken it, the young fella would use the machine gun to keep it back from getting closer to Joia, and Bruno would use a sniper to deal massive damage.
The formation that Bruno had made up within seconds was perfect enough to be effective. The big humanoid monster was being held back, and if things continued in the same way, the monster would eventually die without being able to resist.
But, of course, things weren't that easy. A gun wasn't infinite, as its bullets would run out after a certain period of time…
Because the process of reloading was a necessity, the monster was able to make its first movements closer towards Joia. The Monster couldn't proceed too much however, as there would always be a gun that still had its ammunition.
