Exiting the convenience store, Subaru Natsuki emerges to a busy town inhabited by humans and demi-humans. Using dragons and carriages as transportation, the town is clearly not the modern-day Japan that he is familiar with. However, as someone who spends his days engrossed in comics and games, Subaru assumes that he is a protagonist in this new fantasy world, harnessing supreme magical powers. Much to his dismay, that is not the case and things quickly go awry as he bumps into a group of thugs. Fortunately, a silver-haired beauty named Satella comes to his rescue, while looking for her stolen insignia. In return for her kindness, Subaru offers to help with the search, which eventually leads them to a loot shop. Assuming that the insignia was traded for money, Subaru enters the shop hoping to negotiate with the owner regarding the stolen item. However, much to his surprise, what awaits them is not the insignia but a brutal assassin that leads the two to their demise. But instead of waking up in the afterlife, Subaru is shocked to find himself standing alone in the midst of daytime, as if he never left the town in the first place. Thus, his life in another world mysteriously begins a second time. [Written by MAL Rewrite]

The unaware Subaru Natsuki wakes to see two figures standing in a completely unfamiliar room. The two girls, who turn out to be the sisters Rem and Ram, are immediately teased by Subaru for their synchronistic way of speaking. Before he can go too far, he is interrupted by Emilia—the charming girl he saved at the cost of losing his life thrice using "Return By Death," an ability that allows him to return to a certain "savepoint" each time he dies. Emilia informs him that due to the injury he received while protecting her from Elsa Granhiert, she brought him to the mansion she lives in. There, Subaru meets Roswaal L. Mathers, the clownlike count who owns the residence. While everyone is having breakfast, Subaru requests a reward: to let him be hired as a butler alongside Rem and Ram, which Roswaal quickly grants. Everything seems to be going well for Subaru. However, after a few days inside the mansion, he mysteriously wakes up at the beginning again, reminding him an awful lot of his ability. Can Subaru unravel the mystery behind his death, or will his spirit break first? [Written by MAL Rewrite]
