The Irregular At Magic High School, Vol. 4

One of the centrepieces of the Nine School Competition is the Rookie Games. With only first years being allowed to take part in these matches, First High School's top student, Shiba Miyuki, steps on the stage to display a beautiful, elegant performance. Her brother, Tatsuya, also participates as an engineer who adjusts the athletes' CADs and allows himself a moment to relax only when he admires his sister's appearance in the games.

Though only supposed to be an irregular, a second-rate student, Tatsuya's skills in adjusting the team's CADs give them a strong advantage over the other schools. But as everything goes smoothly, an accident occurs that forces Tatsuya to take centre stage, where he'll have to face the first year known as the Crimson Prince—a first-year ace from Third High School, Masaki Ichijou!

The Irregular at Magic High School, Vol. 4 delves into the action and drama of this pivotal event in the series, showcasing the intricate dynamics between the characters and the high-stakes competition they must navigate.
