Sistine Fibel and her best friend Rumia Tingel are students at a prestigious magical academy, where Sistine hopes to be trained by the best there is in order to unravel the secrets of the mysterious Sky Castle per her grandfather's last wish. When her favorite instructor suddenly retires, his replacement, Glenn Radars, is anything but what Sistine had hoped for. The "Bastard Magic Instructor" appears to be lazy, incompetent, and not that skilled at magic. He is not a certified teacher nor does he have a high rating in the guild. What they don't know is that he is hiding his power and that he is a former assassin from the Imperial Court Mage Corps with a remorseful past who is suffering severe depression. In episode 2 there is an attack on school by the previous instructor, and the BMI is forced to show his true powers. Sistine is baffled as she had misjudged him to be incompetent. As the BMI's students draw him out of his depression, he finds meaning in the activity of teaching. This whole season is complete with a promise for eventful things to come. Topics that are dealt with are Depression, Friendship, Family Relationships, Adoption, Siblings, Following Your Dream, Quest for Power and more.
