On his way back home from the convenience store, Subaru is suddenly brought to another world and he tries to figure out what has happened.

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. Subaru attempts to buy the insignia from Felt and return it to Satella before Elsa arrives at the loot house... but Satella arrives before the negotiations are complete, and Elsa still attacks them.

"After being badly wounded by Elsa, Subaru somehow survived and awoke in the mansion of Margrave Mathers, in the Kingdom of Lugunica. Subaru now lives and works in Roswaal's mansion, working with Ram and Rem, and finally getting Emilia to agree to a date with him. But the day of their promised date never comes as Subaru keeps going back to the day he first awoke in the mansion. He's confused at the thought that he Returned by Death despite having no memory of experiencing anything deadly, but he's determined to repeat his previous actions up to the point of fulfilling his promise with Emilia."

"Subaru's first day at the Roswaal mansion begins for the third time. The first time, he grew weak and died of unknown reasons in his sleep, and the second time, he was killed by an attacker. The sound of chains that he heard as he died the second time replays in his mind, waking him in a terrified, cold sweat. He has no idea what the killer is after, let alone who it is, so he makes a plan to leave the mansion on the fourth night and watch for the attack to happen. Standing before Subaru is someone he never expected. The truth of the attacker's identity leaves him bewildered, and he feels everything crumbling around him as he dies yet again. Then, for the fourth time, he awakes on his first day at the Roswaal mansion. This time, the night of the fourth day passes without incident, and Subaru is stunned as he greets the morning of the fifth day... but then the situation takes an unexpected turn."

Subaru's first day in Roswaal's mansion begins for the fifth time. Determined to save everyone this time, he makes it a point to keep his best smile on his face in order to earn the trust of the mansion's staff. But although he works his hardest to make them like him, his body begins to have trouble keeping up with his heart's intentions. Soon Emilia is unable to bear the sight of him struggling any longer and takes an unexpected action... The scattered pieces of the puzzle finally come together, and Subaru realizes for certain that the shaman who cursed him is in the village at the foot of the mountains. He heads there with Ram and Rem and makes sure all the villagers touch him so that he can find out, with Beatrice's help, who cast the curse. But the truth he finds is not what he expected, and he finds himself rushing toward the village again...

Subaru risked his life to save the children from a pack of Ulgarm, but he was so powerfully cursed that there could be no saving him. Even Beatrice is unable to undo the complex web of curses on him, and says he'll grow weak and die within half a day. The only way he can survive is if the entire Ulgarm pack is defeated, but time is not on his side. Subaru is ready to give up when he learns that Rem has gone into the forest by herself... Knocked unconscious by Subaru's attack, Rem dreams of an event in her past that she and Ram would rather forget... a sin for which Rem feels she can never be forgiven. After waking up, she tells Subaru that she's just committed the same sin again. When the three of them are moments from being cornered by the Ulgarm pack, Subaru takes off to draw their attention so Ram and Rem can escape.
