Grandpa in ch21: "If possible, I'd like you to capture him alive. I want him to tell me how to return the magic he stole to its original owner."
Grandpa in ch22: "So, you got all the magic powers Predator stole? Good. About returning the magic to the myriad original owners, whose lives might have been screwed due to losing their magic, forget it. Now that all the magic power is in our family, it's the best."
Ex: "Of course. Predator stole magic power from 500 people, but none of those 500 are Alice, so they are inconsequential. Their lives don't matter one bit. This power is now dedicated to keeping Alice happy, which is the only thing that matters in the universe."
Truly the shining beacons of morality, these fellows. This is a story about a villainess marrying the villain, haha.
