I think Rapdevil is the one who attacked Yogurt and Miseng, and the other regulars will have to beat him.

Because: if Viole wanted to take the numbers down to below 7, he would have killed Yeon and Lurker, but he just froze them.

Also, Devil is drawn as menacing, so SIU clearly wants him to be the bad guy.
