In the canonical storyline of Re:Zero, Natsuki Subaru has not married anyone as of the latest published content. The narrative strongly positions the half-elf Emilia as his primary and most probable future wife, with their relationship being the central romantic focus of the series. His bond with the demon maid Rem, while profoundly deep, exists in a separate, non-canonical branch for any marital outcome.
Subaru’s Canonical Trajectory with Emilia
Subaru’s devotion to Emilia is the cornerstone of his character development. From their first meeting, he has consistently chosen her, with his motivations evolving from initial infatuation to a mature, self-sacrificial love. The narrative meticulously charts their emotional growth. Emilia, initially closed-off due to her past, gradually opens up to Subaru, reciprocating his feelings in later arcs. Author Tappei Nagatsuki has structured the story’s major plotlines around their partnership, strongly indicating a romantic endgame. Key story milestones, like their heartfelt moments in the Sanctuary arc and mutual declarations of support, solidify this trajectory. The series' overarching quest for Emilia to become the kingdom's ruler also positions Subaru as her future king-consort, a role heavily implied in the narrative’s world-building.
Rem’s Position and the “Sloth If” Alternate Path
Rem’s unconditional love for Subaru is undeniable and forms one of the story's most iconic relationships. However, within the main anime and light novel timeline, a romantic union is not where the story is headed following the events of Arc 3. Her deep affection is instead channeled into unwavering support for Subaru’s goal of helping Emilia. The marital scenario with Rem is explicitly explored in a published "What If?" side story, often called the Sloth If or Rem If. In this branching path, Subaru elopes with Rem, they marry, have two children, and live a peaceful life. This story is officially authored but exists outside the main canon, serving as a popular "what could have been" scenario that highlights the strength of their bond under different choices.
Analyzing the Polygamy Speculation
Speculation about a polygamous resolution where Subaru marries both Emilia and Rem stems from the fictional Lugunica Kingdom's laws, which permit polygamy for royalty. While this provides a theoretical framework, there is no canonical evidence or author statement supporting this outcome for the main story. The narrative consistently focuses on Subaru and Emilia’s exclusive romantic development, and Rem’s character arc has moved toward supporting that future. Pursuing polygamy would contradict the established emotional growth and central themes of choice and consequence. Therefore, while a fascinating fan theory, it remains highly unlikely to be realized in the official storyline.
The table below clarifies the relationship statuses based on canonical and alternate content:
| Character | Relationship to Subaru in Main Canon | Potential Marital Status | Source / Context |
|---|
| Emilia | Primary love interest; reciprocated romantic partner. | Most likely future wife in the story's conclusion. | Central plot of main light novel/anime series. |
| Rem | Deeply beloved comrade and unwavering supporter. | Married in a non-canon alternate timeline only. | Published Sloth If/Rem If side story. |
| Polygamy (Emilia & Rem) | Theoretical legal possibility in-setting. | Purely speculative, no narrative support. | Based on in-world law, not story direction. |
Ultimately, all credible narrative evidence points toward Emilia. The story is a gradual journey toward their official union, with Rem’s role being that of a cherished family member and key ally in achieving that future.
