Re:Zero - Starting Life in Another Worldis a bleak isekai anime starring Natsuki Subaru. Subaru is transported to a new world, and like most isekai protagonists, he gets a new power. Unlike most other isekai protagonists, Subaru’s power is brutal. Called Return by Death, Subaru’s power works exactly as the name implies, as he’s allowed to return to a predetermined point in time once he dies.It allows him to solve a lot of the mysteries within the series, but not without dying each time.
To be a good show likeRe:Zero,a series doesn’t even need to be an isekai. The biggest theme inRe:Zerois how bleak life can be, and thanks to Subaru’s relentless determination, how to overcome that bleakness. The best shows that can be compared toRe:Zerohave to involve a little bit ofdarkness, melancholy, and some existential dread at the same time.
