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.

This IF route details the sweet daily life of their family of four (a family of five was shown in an anime easter egg scene), from the birth of their children to the small moments of family life, presenting a warm world starkly different from the cruelty of the main story. This image of a blissful "Wife Rem" fulfills the desire of the vast "Rem Sect" fans for her to attain happiness.

A Fleeting Glimpse in the Anime

Although Long-Haired Rem primarily exists in the novel's IF short stories, a special easter egg was added at the beginning of the first episode of the anime's second season, when Rem had her "existence" and "memories" devoured by the Archbishop of Gluttony. In the moment Rem's consciousness faded, the anime flashed to a scene from the IF route where she was married to Subaru and had children. The image of Long-Haired Rem smiling through tears served both as a tribute to the IF route and added a layer of heartbreaking beauty to the tragedy.

This brief scene allowed many anime viewers unfamiliar with the IF route to see the Long-Haired Rem image for the first time, sparking extensive discussion and attention.

Conclusion: A Beautiful Dream Dedicated to the Fans

The image of Long-Haired Rem is a beautiful dream given by the author to the fans, an imagining of happiness about "what if another path had been chosen." She is not merely a change in appearance but symbolizes a fulfilling life, far from conflict and filled with familial warmth. Although in the main story, Rem remains asleep, waiting to awaken, this image of the long-haired wife from the IF route has long become an indelible classic in the hearts of fans. Through various merchandise like figures and body pillows, her charm continues to be shared.
