The third enemy tried to grab Rain's attacking arm and give the chance to the others to hit him, but that didn't work well either. His arms ended up broken, and while he stopped Rain's punch, the next one couldn't be blocked.
From that point onward, the enemies had the chance to attack Rain from the sides, and while he felt his bones cracking with each hit, he ignored the pain and kept hitting them one after the other.
Before long, all of that battalion was looking at Rain while they were fighting other targets. His fighting style was unusual for humans, and he was the strongest on their side of the battlefield.
When they had the chance, the enemies kept charging at him, trying to stop his endless charge. However, they only met their ends and only had the chance to attack him once or twice.
