Rem

Rem is one of the twin maids of the Roswaal Mansion and a member of the oni clan, bearing only a single horn due to a painful chapter in her past. She initially harbored suspicion and prejudice toward Natsuki Subaru, but after he risked everything to save her, she underwent a profound transformation—channeling her entire heart into unwavering devotion and love for him. Serving as Subaru's most essential emotional anchor, her heartfelt confession became the turning point that inspired him to rise from despair and start anew, cementing her status as one of the most beloved characters in Re:Zero.
