Beelzebub punched Rune in the face. His punch was so strong that it made Rune flew away with just one hit. It's not surprising, since Beelzebub has been devouring thousands of creatures every time, he acquired their mana and strong abilities when it comes to fighting.
The smile that had long vanished from his face came back after seeing his successful attack. "Was that fun? If you show me your fur right now, I might hold back before killing you."
Rune quickly stood up while his face was bleeding. He couldn't feel anything. As if the moonlight shining on him has been helping him to feel nothing from the attacks of Beelzebub.

"Rune, you shall protect the people precious to you."
