After an explosive encounter with a powerful magic user, Megumin informs her parents that she wants to study explosion magic at the Crimson Demon magic academy called the Red Prison.
As the day of both their graduation and the awakening of the Dark God seem to draw ever closer, Megumin gets the feeling Yunyun is keeping secrets from her.
Megumin has finally achieved her dream of learning Explosion magic, but it takes more than massive eruptions of power to make a living. Saving enough money to set out on her journey might take longer than she ever thought.
After finally arriving in the city of water, Arcanretia, Megumin is once again having trouble saving up for the next leg of her journey. But she may have found an unexpected source of help in the Religious Order of Axis.
Megumin has become acquainted with Father Zesta of the Axis Sect, just in time for him to be arrested thanks to a letter delivered by Yunyun. Can the two Crimson Demons repay his hospitality by proving his innocence?
A high-ranked demon has begun lurking the woods near Axel, and the local adventurers--including Megumin and Yunyun--are trying to do something about it.
