"It looks like I underestimated you, Wolfe Noxus. Your power is growing at a more impressive rate than I expected, but an agreement is an agreement. 500 units a day. But if you volunteer to donate extra, the teachers will thank you for reducing their workload." Headmistress Peach offered.
Wolfe noticed that there was no offer of payment, only of allowing him to volunteer mana. The Witch was playing it safe, probably so he couldn't load up on Academy credits and bias the advancement of his Witches by just buying everything they wanted.
"I will take a few extra Crystals and think about your offer. I'm sure the professors would appreciate the effort." Wolfe replied, carefully not agreeing to actually do it.
