Subaru heads to Roswaal’s mansion in hopes of finding out what’s going on there and how he can fix it. He has Frederica and Petra evacuate to Arlam Village to protect them from Elsa’s attack, then heads to Beatrice’s forbidden library. He tries to get Beatrice out of the library, but her wishes don’t align with his plans, and their discussion goes nowhere. Then, against all logic, Elsa finds her way into the forbidden library…
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.
