Rem

34
Rem is the devoted blue-haired maid of Re:Zero, a demon twin whose fierce loyalty to Subaru Natsuki turned her from a minor early character into one of the most beloved heroines in modern isekai. Her massive popularity boost mid-series made her a fandom phenomenon in her own right, and Rem hentai doujinshi are among the best-represented tags in Re:Zero fan content.
