The relationship between Satella and Natsuki Subaru forms the central mystery of the Re:Zero series. From the moment Subaru arrives in the fantasy world, he smells of the Witch's miasma and possesses the ability to Return by Death, a power directly granted and managed by Satella. While casual viewers might write this off as standard dark fantasy tropes, the narrative drops heavy hints that their bond stretches far beyond a simple monster-and-hero dynamic. Satella claims she loves Subaru deeply, thanking him for giving her light, holding her hand, and showing her the outside world—yet Subaru himself has no memory of these events.
Unpacking this obsession requires looking past the surface-level madness of the Witch of Envy. Satella's fixation stems from events rooted 400 years in the past, involving split personalities, possible time travel loops, and historical figures like the sage Flugel.
The Dual Nature of Satella and the Witch of Envy
To understand why Satella obsesses over Subaru, you first have to separate her from the entity known as the Witch of Envy. During the Great Calamity 400 years ago, Satella absorbed incompatible Witch Factors—specifically the Envy factor—which drove her insane and created a second, destructive personality.
- Satella represents her original, lucid personality. When she interacts with Subaru in the Shadow Garden, she speaks with tenderness, remorse, and deep affection. She expresses a desire for Subaru to eventually save her by killing her.
- The Witch of Envy acts as the violent, jealous manifestation that controls her body when the mind slips. This persona guards Subaru fiercely, curses him if he tries to reveal his power, and slaughters those around him when taboos are broken.
This duality explains why Subaru experiences two very different forms of interaction. Sometimes he encounters overwhelming, suffocating malice, while other times he meets a gentle woman weeping for his safety. Both facets of her psyche share an absolute devotion to Subaru, but they express it through starkly contrasting methods.
Why Does Satella Love Subaru So Much?
Satella insists that Subaru saved her life, showed her kindness when she was entirely alone, and shared intimate moments with her. The core contradiction is that Subaru has lived a normal life in modern Japan and only remembers being summoned out of nowhere.
Fans and scholars of the source material generally point toward a few leading explanations for this memory gap.
The Flugel Connection
A dominant theory in the community connects Subaru to Flugel, a legendary sage from 400 years ago who worked alongside the sword saint Reid Astrea and the first generation of heroes. Flugel came from the same modern world as Subaru, spoke using similar phrasing, and left behind earthly trees and items.
If Flugel was Subaru's past life, or an earlier version of him, Satella's memories belong to that historical timeline. Satella fell in love with Flugel centuries ago. When Flugel vanished or died, the grief contributed to her absorption of the Envy factor. Pulling Subaru into the world was either an act of resurrection, a desperate summoning of her lost love's soul, or a reaction to a temporal loop.
Time Travel and Lost Loops
Another theory suggests that Subaru's authority of Return by Death operates on a scale much larger than single-season resets. If high-level spatial and temporal magic is involved, Subaru may have traveled 400 years into the past during an undiscovered timeline, met Satella, shaped her worldview, and then returned or lost his memories due to the strain of time displacement. Satella remembers every single interaction because her existence spans across these anomalies, leaving Subaru caught in a web of obligations he hasn't experienced yet.
The Role of Return by Death in Their Bond
Satella didn't just summon Subaru; she anchored him to life through Return by Death. Every time Subaru dies, his consciousness rolls back to a save point, sparing him permanent extinction.
However, this power functions as a double-edged sword:
- Protection: Satella refuses to let Subaru die because she values his life above all else, using her authority to manually rewind time.
- Torment: The psychological toll of watching his loved ones die repeatedly destroys Subaru's mental stability. Satella has noted that she wishes for Subaru to value his own life, indicating that his self-destructive martyrdom frustrates her despite her protective spell.
When Subaru attempts to speak about his ability to others, the Witch's hand squeezes his heart. This punishment is designed to protect him from being dissected or exploited by hostile factions in Lugunica, though it often feels like a cruel torture method to Subaru.
How Satella Compares to Emilia
A persistent element of the plot involves the uncanny physical resemblance between Satella and Emilia. Both are silver-haired half-elves with similar facial structures, leading many characters in-universe to fear and persecute Emilia simply because she looks like the worst mass murderer in history.
Despite popular theories claiming Emilia is Satella from the future, author statements and side stories separate them as distinct individuals. The physical similarity remains a deliberate narrative mystery. Whether Satella designed her appearance, whether half-elves carry specific historical traits, or whether bloodlines run deeper than currently revealed, Subaru's immediate devotion to Emilia mirrors his subconscious—or past-life—attachment to Satella.

Frequently Asked Questions
Did Satella summon Subaru on purpose?
Yes, it is heavily implied that Satella used her magic to reach across worlds and pull Subaru into the fantasy kingdom. She targeted him specifically, which is why he spawned close to Emilia and immediately received the miasma scent.
Why does the Witch's scent get stronger over time?
The miasma clinging to Subaru intensifies as he absorbs more Witch Factors from defeated Sin Archbishops and as his soul undergoes repeated stress through Return by Death. This makes magical beasts and powerful entities react aggressively toward him.
Does Satella want to destroy the world?
No. The destruction attributed to her was caused entirely by the Witch of Envy personality when it overrode Satella's consciousness. Satella herself is remorseful, peaceful, and trapped near the Great Waterfall.
Will Subaru ever remember his past with Satella?
As the story progresses through later arcs in the web and light novels, more context regarding the sage Flugel and the events of 400 years ago surfaces. Whether Subaru regains explicit memories or pieces them together remains a primary driving conflict for the narrative's endgame.
