Re:Zero: Rem and I Return by Death Together

A Re:Zero fanfic with Subaru as the sole protagonist, a university student version. He becomes overpowered midway through, and won’t be dumbed down. The story’s got a bit of everything. Rem returns from death along with him. Subaru transmigrates, and a god randomly grants him a divine power [currently the Degradation Line]. With his intelligence and mental strength enhanced, how will Subaru survive in this dark and dangerous other world…? Subaru: “Why? Why is this world so hostile toward me?! Am I the only one who can handle this? Are you all really depending on me?!” “Why is this damn BGM playing again?! Who’s lost a point this time?!” “Huh…?! Weren’t we supposed to stick together? You’re fighting among yourselves again?!” Besides keeping himself safe, Subaru seems to have to keep an eye on his teammates’ mental states at all times… Wait, Rem, why are you saying I should come find you in my next loop? The story stays pretty normal until the mansion arc, but after that… What do you mean there are monsters mixed in with the magical beasts? What do you mean there’s an adventurer party led by someone named Kazuma looking for him?! What?! And the Spear Hero is going to challenge Gluttony to a duel?! What even is this other world?!
