Invincible Colorless Butler

The girls' battle against Draco was fierce. Ziel stood not far from their battlefield and watched quietly. Even though he looked indifferent on the surface, he was on alert and ready to help the girls when they fell into a dangerous situation.

Ziel tries not to interfere in their fight unless the girls are in danger. They had to experience a life-and-death battle against a primeval god to increase their combat power rapidly.

He was satisfied when he saw the excellent cooperation of the three girls. They seemed to know each other and could combine their attacks almost perfectly.

"Their strength had grown by leaps and bounds. But they were still far below the primeval gods, whether in strength, speed, or combat experience. If this world didn't suppress Draco's power and they didn't work together to fight against him, they would surely have lost as soon as they started the battle." Ziel muttered while watching the girls battle.
