The battle between the vanguard of Black and the Berserker of Red was completely one-sided.

The halberds of the homunculi bit into his shoulders. The fists of the golems buried themselves in his face, impacting directly with enough force to shatter steel. However, these attacks did not make the smile disappear from Berserker's face. If anything, his grin widened.

Berserker made no attempt to avoid their attacks in the first place. In fact, he seemingly took pains to leap into their paths.

He took their beatings again and again, simply taking it all. Regardless of pain and injury, his expression was always one of ecstasy. Soon, even his attackers—tireless homunculi and golems—hesitated and stopped. That was when Berserker moved.
