Rem

In the past, Ram and Rem lived in a demon village where the birth of twins is considered taboo. Ram was a prodigy, while Rem struggled with life. One day, Ram had her horn cut off and Rem had been blaming herself since then. Back in the present, Rem regains her senses after Subaru knocked her unconscious. Subaru, Ram, and Rem run away from the Mabeasts, and they encounter the dog shaman behind the attack. Subaru stays put to fight the shaman, who has transformed into a fearsome beast, in order to let the twins escape. Subaru stabs the shaman with his broken sword, but the attack did no damage. Just before he was about to be attacked, Roswaal arrives to defeat the shaman and the remaining Mabeasts, which removes all of the curses on Subaru. Back at the mansion, Subaru wakes up with Rem in the room, and Subaru tells Rem to keep on living for the future rather than to feel sorry for herself. Subaru goes outside to talk with Emilia and the two agree to go on a date the next day.
