The Irregular at Magic High School, Vol. 22 (light novel)

Tatsuya hasn’t won many new fans with his less-than-friendly behavior at a recent gathering of the Twenty-Eight Families who were in Yokohama to discuss the concerning rise in anti-magician movements. As usual, he puts Miyuki’s safety above all else, even if it means souring relations between the Yotsuba and the other clans.
And that’s not the only problem he has to be worried about. Quite a few people are having doubts as to where Tatsuya’s loyalties really lie, and it seems they’re willing to go to extreme lengths to find out!
