Weapon and Magic Training
Her teachings made them start thinking for themselves. They understood that once they were assigned a mission and if something unexpected happened, they wouldn't be able to react and would have to wait for orders.
This was something that Saito was unwilling to see. He didn't want them to be brainless soldiers. They were the first ones to die. He wanted them to have the ability to think in different situations and make the optimum decision.
They realized that Saito was willing to let them do almost anything as long as they didn't go against him or his orders. As long as it was acceptable, he would allow them to do it.
After that week, it was the magic training week. The morning exercise remained for all of them. However, the first half of the weapon training had now changed to magic training. Saito knew that he couldn't teach them everything about magic in a short period of time.
