After witnessing an unrealized present, Emilia completes the second trial and begins the third and final one. Ram and Puck are fighting their hardest to stop Roswaal. Each of them is doing it all for the sake of realizing their own goals. The battle between Garfiel and Elsa at Roswaal’s mansion is also growing more and more intense. As Subaru is being chased by a guiltylowe, he declares that it’s time to make use of his unparalleled knowledge of the modern world and lures it into a closet…
Natsuki Subaru is summoned to a parallel world on his way home from the convenience store. He's entranced at first by the fantasy world suddenly stretching before his eyes, but the cute girl he believes summoned him is nowhere to be found, and soon enough he's utterly lost. Then a gang of punks surrounds him, but he quickly learns that he doesn't have any of the powers that he thought all people transported to a parellel world should have. Just when he's about to be beaten senseless, a girl appears...
After being attacked by someone the first time, sliced open by Elsa the second time, and stabbed in the back by punks the third time, Subaru should have been dead, but found himself back where he started in the same parallel world every time. He finally realizes he’s acquired the power to go back to the time and place he started from, which he calls “Return by Death.” In hopes of changing the fate awaiting Felt, Satella, Old Man Rom, and himself, Subaru takes off for the fourth time.
