Will is under attack. Julius is using one of the Twelve Secret Ice Magics invented by the genius mage Elfaria. The arena falls silent in shock and admiration. But no one knows Elfaria's magic better than Will and his counterattack starts now.

Surrounded by countless monsters, Will and the others are in trouble. Even so, Will says they should fight. Faced with an Evil Grand Duke, the same monster that plunged them down to floor 11, will the party retreat or will they make a stand?

Will and the others fall into a dangerous region of the dungeon. Separated from the others, Wignall reluctantly opens up to Will, sharing the source of his insecurities. Meanwhile, two mages cloaked in dark magic appear before Colette and Lihanna.

The all-student praxis begins. Lihanna, Wignall, Julius, Sion, and Will, with Colette tagging along, dive into the dungeon together. Though Will's usefulness is questioned, they push forward to floor 10 and their primary target—the Luminous Naberus.

With Colette's help, Will enters the Grand Magic Festival. The crowd goes wild watching him advance with Colette's magic and his own astounding physical strength. But for the third member of their team, it's a reminder of a painful humiliation.

Sion suddenly attacks Will in the middle of their event at the Grand Magic Festival. Sion's emotions fuel his magic as Will struggles to understand Sion's actions. Meanwhile, Julius draws ever closer to the stadium and winning the event.

Driven by a childhood promise, Will Serfort is determined to rise to the top of Magical Academy Rigarden and become one of the greatest mages the world has ever seen. There's just one problem... Will can't use magic.

Sion's defeat of a formidable monster is the talk of the academy, but only he and a few teachers know the truth. Edward in particular can't accept it, so, as a teacher at the academy, he prepares a special lesson for a particular student.

Led by wand and sword, Will strikes at the Grand Duke, but even its defeat may not be enough to grant them escape from the dungeon. Meanwhile, Workner and Edward race to reach them in time, but things look bleak. Still, Will isn't one to give up.

Lady Elfaria issues an order to the academy—gather Frost Walker ice cores. Will quickly heads into the dungeon, but it's already full of others trying to fulfill the order. As he looks for a less crowded area, he spots a fellow student under attack!

The whole academy is buzzing about the upcoming festival, but Will hasn't entered any of the events due to his lack of magic. Instead, he focuses on his studies and earning money for tuition. Then, a top student from his year shows up where he works.

Students at the academy suddenly see Will in a different light and he receives a flood of invitations to join their parties for the upcoming all-student praxis. Colette panics and arranges a date with Will, but an unexpected third party shows up.
