The Origin of Rem's Long Hair Style: Revealing the Happy Future with Subaru in the Re:Zero IF Route
Preface: The Gentle Wife Who Only Exists in "What If"
In the main story of Re:Zero − Starting Life in Another World, Rem, with her signature light blue short hair and selfless, devoted love, has captured the hearts of countless fans worldwide. However, many images of "Long-Haired Rem" circulate online, showcasing a mature, wifely charm different from her main story persona. Where does this look actually come from? The answer lies in a special gift author Tappei Nagatsuki prepared for the fans—the **IF Route (Side Story)**.

The Origin of the Long Hair: The Happy Ending of the "Greed IF Route"
Rem's long-haired look primarily originates from officially created IF short stories, specifically the storyline known as the "Greed IF Route" or "Rem IF Route"—Re:IF − Starting Life in Another World from IF.
This story stems from a key decision point in Episode 18 of the anime's first season. In the main storyline, when Natsuki Subaru, suffering a mental breakdown, asks Rem to run away with him and escape everything, Rem refuses him with a heartfelt confession, inspiring him to regain his resolve. However, in the "Greed IF Route," the story takes a different possibility: Rem agrees to Subaru's request.
The two abandon the Royal Selection and all its conflicts, running away to Kararagi to live a peaceful, secluded life. In this world line, as time passes, Rem lets her hair grow long, transforming into a gentle and virtuous wife and mother. This is the official origin of the "Long-Haired Rem" image.
Family Life in the IF Route: Mother of Two Children
In the "Greed IF Route," Long-Haired Rem and Subaru form a happy family and have two adorable children:
- Eldest Son—Natsuki Rigel: Inherited Rem's blue hair and Subaru's somewhat fierce-looking eyes. He has a lively and active personality and possesses the bloodline of the Oni.
- Eldest Daughter—Natsuki Spica: Inherited Subaru's black hair and Rem's blue eyes, she is the apple of the family's eye.
