Mahouka Koukou no Rettousei: Tsuioku-hen

Miyuki and her older brother Tatsuya's close relationship nowadays is hard to reconcile with their past. Three years ago, Miyuki found her brother's presence uncomfortable, and their family treated him poorly despite his exceptional abilities as a Guardian. This role allowed him to protect Miyuki as she lived a normal middle school life, but his lack of emotional expression and individual thoughts was particularly bothersome to her. Their dynamic is about to change during a family trip to Okinawa.
