The Crimson-Eyed Wizards
Long before she meets Kazuma, a young Megumin accidentally unleashes a monster that attacks her, but she is saved by a mysterious and powerful mage who uses explosion magic to destroy the monster. Inspired, Megumin asks the mage to teach her how to cast explosion magic, but the mage refuses, cautioning her that explosion magic comes with many downsides. Megumin returns home, and is able to enroll in the Red Prison magic academy thanks to her parents making an important sale. At the academy, she meets Yunyun who declares that she will be Megumin's rival, and they soon form a grudging friendship with each other. Megumin then learns during her studies that explosion magic is not taken seriously by the Crimson Demon clan, as it is highly impractical and rarely cast. Regardless, Megumin decides to learn how to cast explosion magic, no matter what.
