The Irregular At Magic High School: Summer Vacation Vol. 1

With only a few magic users in Japan, they’re a rare commodity and forced to attend one of nine magic-related schools, each of which focuses on a different aspect. Among these users is Tatsuya Shiba, a user who’s considered magically inept but manages through his unusual technical knowledge, combat abilities, and unique magical techniques, making him the “irregular” of The Irregular at Magic High School, a popular fantasy series written by Tsutomu Sato.
Trouble stirs following the Yokohama Disturbance Arc as Maya Yotsuba calls Tatsuya and Miyuki over. The incident at the Great Asian Alliance harbor wasn’t Tatsuya’s first time using the matter detonation technique, but could using that have caused even more trouble for Tatsuya?
