If I want to save others I need power. To protect my friends and everyone else in the kingdom, I must have more power than I do right now. This is just this sort of world, power dictates supreme, so unless I have enough I can't even leave home properly, much less help others as I want to. Even as a member of a magic knights squad, the chances of an assassin coming after me and hurting other is scary high. What the magic king is offering me is exactly the solution I have been looking for. A chance to train under him and learn from the best on how to use my grimoire to my maximum potential, but before I agree I must ask him something.
