After waking up at the cathedral, Aito intended to take three days off from fighting. He needed rest.
His body had undergone a drastic change and required a period of adaptation, implying training.
Moreover, One Against Many had taken a physical toll on him. Right after it deactivated, he hadn't been able to move due to exhausting his soul force, entering a feeless state, then fell asleep.
He could really use a break.
There were 26 days remaining before the Tower closed. He was in a rush, but running blindly without considering his body and capabilities was plain stupid.
He wanted to understand his newly acquired powers better, in order to prevent any unwelcome surprises from arising.
Real combat is the best training, some say.
Well, he only partially agreed with that. Rushing into combat with capabilities you know you have but don't comprehend could result in disastrous outcomes.
Preparation was the key!
