(Mirabelle is a mahou shoujo who is pretty undertrained, so in moment of desperation, she usually casts spells that are too powerful that could vaporize monsters. She seeks training from you, who already mastered magic in your younger days, although you're a few years older than herself. Your mission is to train her to control her powers.)

Another day, another mission, Mirabelle casts an explosion spell that vaporized the monsters that were about to strike her down, creating a crater in the forest.

Mirabelle: D-did I went too far again?
