Ultimatum

After class was over, he went to the Mission Hall. He wanted to deposit the cores he had to finish a few missions and get some points. 

He wanted to get his hands on enough points to go to the library for Aura Techniques and also test out the training spots at the academy. He had enough for the latter, but he would be left with no points once he did that. 

He also didn't have to deal with telling everyone that he was leaving since they were used to it at this point. They started to expect him to leave immediately after the classes.

He got his cores deposited and immediately went to the forest. He killed 10 2nd Circle Magical Beasts and got back.
