The Irregular at Magic High School: Reminiscence Arc

As Tatsuya and Miyuki Shiba begin their second year at First High School, their reputation as an exceptional, inseparable pair seems unquestionable. Yet only four years earlier, that closeness didn’t exist—Miyuki, still in middle school, kept her distance from her older brother.

In their household, Tatsuya was treated less like family and more like a guardian assigned to Miyuki: a servant expected to follow orders, valued for utility rather than feelings or autonomy. Everything shifts during what should have been a simple trip to Okinawa, when the vacation turns into a dangerous ordeal that changes their relationship for good.
