The question “Who will Subaru end up with?” has always sparked heated debates among Re:Zero fans. However, according to the series creator Tappei Nagatsuki, the number of girls who truly have romantic feelings for our “resurrecting hero” is far fewer than you might think.
An interesting fact is that back in 2013, three years before the hit anime premiered, Tappei revealed that the original story only featured three main girls who developed romantic feelings for Subaru. Later, this number was increased to four.
It’s important to clarify that the term “main girls” here refers to those who have romantic feelings for Subaru, not just important characters in the plot.

So who was the fourth girl to join this list? Based on interviews and fan deductions, that girl is none other than Rem. Few realize that Rem was not originally intended to fall deeply in love with Subaru. But thanks to her unexpected character development and overwhelming fan support, the author changed course, turning her into the beloved “nation’s wife” and the series’ shining star.
Who are the original three muses?
Drawing from the Light Novel’s storyline, dedicated fans have made convincing guesses about the original three names.

The first is Emilia. As the series’ main heroine, her journey to recognize and return Subaru’s feelings forms the core of the entire story.

The second is Satella, the “Witch of Envy.” From the start, Satella has consistently expressed her intense love for Subaru. She is a key figure, and her feelings for him are undeniable.

The third is Shaula. For those who have read up to arc 6 of the Light Novel, Shaula is an unmissable name. Her relationship with Subaru holds many mysteries and deep feelings that transcend time.
Although this list of four girls is based on indirect confirmations and community speculation, it shows that Tappei Nagatsuki has a very carefully planned ending for Re:Zero. The fact that Rem, an “unplanned” character, became the series’ icon highlights the author’s unpredictable creativity.
