A bombing during the Ten Master Clans Conference forces Masaki Ichijou, the Ichijou family's eldest son known across the magic world as the Crimson Prince, to transfer from Third High to First High to investigate. The move also makes him a classmate of Miyuki Shiba, the girl he's admired from a distance. This volume adapts a side chapter from volume 19 of the light novel series, following Masaki's side of the Master Clans Conference investigation.
