With how chaotic the situation was, and with him being fully transformed, Werewolf couldn't precisely control his strength. Because of that, he was expecting to crush the arm he reached out to grab, even if he didn't intend to.
Still, even though the force he put into his hand would have been enough to bend the iron bars at the gym, the arm he caught didn't crack or bend.
His fingers were bent around the entire finger, hiding most of it, but the upper arm and the shoulder it was connected to were visible, and so was the head of whoever that arm belonged to. What looked back at him weren't the eyes of a person, however.
A demon. Blue skin, sharp, knife like horns, and eyes gleaming with crimson malice. The sight froze Werewolf for a moment, and that was all it took for another one of the demons to attack him from a different direction.
