Iceblade Sorcerer Ray White has continued to hide his identity while enjoying the everyday academy life he always wanted at Arnold Magic Academy, surrounded by friends such as Amelia Rose. But a new challenge arrives in the form of an invitation to the Magicks War, a large-scale magical battle tournament fought by three-person teams that crosses academy boundaries. As Ray and his friends prepare to take part, unsettling shadows begin to creep closer, and the other Seven Great Sorcerers besides Ray himself start making their own moves.

Ray White is the one who inherited the title of Iceblade Sorcerer, known as the world's strongest among the Seven Great Sorcerers. Haunted by the trauma of his past, he suppressed his own magical power and enrolled at Arnold Academy as its only commoner. Despite facing contempt from noble-born students at first, he proved his strength while standing up to the conspiracy of an organization targeting elite sorcerers called the Eugenics, and gradually earned trust and friendship. He is earnest by nature but sometimes lacks common sense, leading to baffling behavior.

Amelia Rose is a daughter of one of the three great noble families and a student at Arnold Academy. She is one of the top five sorcerers at the school and a hard worker who, after training with Ray, won the Magicks Chevalier rookie tournament. She has become aware of her feelings for Ray during their school life.

Ariane Olgren is a daughter of another of the three great noble families and the top student at Diom Magic Academy. She longs for a world of love and peace. After a fierce battle with Amelia during the Magicks Chevalier tournament, the two reconciled from a long estrangement, and Ariane now aims to participate in the Magicks War, recruiting Ray and Amelia for her team.

Evi Armstrong is Ray's roommate in the dormitory. He is a simple and kind-hearted young man obsessed with muscle training, and he was the first to befriend Ray without regard for his commoner status.

Elisa is a shy, bookish half-elf girl in the same class as Ray and Amelia, often hiding her long ears under a hood. She is a genuine magic user with outstanding knowledge and skills.

The story is set at Arnold Magic Academy, where elite sorcerers from across the world gather. The narrative arc centers on the Magicks War, a tournament that brings together teams from different academies, as well as the broader movements of the other Seven Great Sorcerers beyond Ray. Previously, Ray confronted the Eugenics organization that targeted elite sorcerers and won the trust of those around him. In this new chapter, his peaceful school life is interrupted by the looming tournament and new threats.
