Everything was set up in Raze's mind. He would deal with the trouble that was taking place in the Demonic Faction, in turn gaining strength, and afterward, he would have a meeting with Belil from the Neverfall Clan.
Before then, he would head back to the Dark Faction, the academy, to see if everything was okay, because there would always be this worry in the back of his mind that Alter had sent one of these so-called Deleters to the scene.
For one, Raze didn't think Alter would act so fast. If they truly felt he was the real Dark Magus and a person who could rise to the top of the Dark Faction, they would play the slow game and try to get him in one swoop.
That was unless they truly believed in the strength of these Deleters. As for the second reason, it was because Raze believed in Himmy, believed that he would do as he said and buy time.
