Kai Ijuuin

Kai Ijuuin is a first-year student at Tensei Academy and a self-proclaimed prodigy who wields Wizard-class decks with remarkable precision. Known for his data-driven approach to dueling, he often predicts the exact turn he will claim victory—and delivers on that promise. Initially arrogant and distant, he addresses those he does not respect by their full names as a subtle show of disdain. As the story unfolds, however, he evolves into a steadfast ally, offering calm, calculated support to the main cast and cementing his role as the indispensable strategist of the Shadowverse Club.
