In the intricate fantasy world of Re:Zero - Starting Life in Another World, protagonist Subaru Natsuki defies the standard overpowered isekai hero trope. Instead of wielding raw magical destruction, his power centers on Authorities—unique, conceptual abilities tied to Witch Factors rather than traditional mana. Understanding what these Authorities are and why they matter fundamentally shifts how Subaru operates from a helpless bystander into a tactical linchpin.
An Authority diverges entirely from standard magic or Divine Protections. While normal magic draws on ambient mana regulated by the world's structure, an Authority operates on a conceptual rule-bending level, often reflecting the deepest psychological desires or traumas of the user. Subaru absorbs these Witch Factors unintentionally as he defeats or encounters Sin Archbishops, slowly accumulating abilities that alter his survival odds. Far from turning him into an invincible fighter, these powers emphasize his role as a strategist who must protect his allies through coordination and sacrifice.
What Are Authorities in Re:Zero?
To understand Subaru's specific toolkit, you have to look at how Witch Factors function. In the world's lore, these factors carry the corrupted remnants of the Witches of Sin. When a Sin Archbishop dies, their Witch Factor seeks out a compatible host.
Unlike archbishops who warp these powers into violent, ego-driven manifestations, Subaru's weak constitution and hyper-protective fixation on his friends cause his Authorities to mutate differently. They typically manifest as low-output, utility-heavy variations of the original sins. Instead of dominating enemies, they focus on burden-sharing, minimal telekinesis, or temporal anchors.
Breakdown of Subaru's Known Authorities
Subaru doesn't just rely on his infamous loop-resetting ability; he gradually unlocks distinct powers tied to specific sins. Each one changes his tactical options significantly.
Return by Death and the Authority of Envy
While initially viewed simply as a curse or a mysterious mechanic, Return by Death functions as Subaru's primary and most potent Authority, rooted in the Witch of Envy. Every time Subaru dies, time loops backward to a specific checkpoint, allowing him to gather information and alter future outcomes.
The weight of this power matters because of its psychological toll. Subaru bears absolute isolation; he cannot speak about the loops without triggering a lethal shadow enforcement from Satella. It transforms every minor interaction into a high-stakes puzzle where a single misstep destroys everyone he cares about.
Invisible Providence and the Authority of Sloth
Acquired after defeating Petelgeuse Romanee-Conti, Subaru's version of Sloth manifests as Invisible Providence. Unlike Petelgeuse's multiple devastating unseen hands, Subaru can only summon a single, weak, semi-transparent hand at a very short range.
- Range and Limits: It can barely lift light objects or pull small switches a few feet away.
- The Physical Cost: Overusing it strains Subaru's physical body intensely, causing severe internal feedback.
Despite its low combat utility, it matters because it provides unexpected utility in tight spots, such as grabbing a distant lever or breaking a stalemate when his hands are physically pinned.
Cor Leonis and the Authority of Greed
Unlocking during the intense trials of later arcs, Subaru's adaptation of the Greed Witch Factor becomes Cor Leonis (Latin for "Heart of a Lion"). Regulus Corneas used Greed to make himself untouchable and invulnerable by freezing time around his body. Subaru's version, however, turns inward toward his allies.
- Sensory Link: It grants Subaru a sixth sense to perceive the physical locations, emotional states, and health conditions of his comrades.
- Burden Sharing: He can absorb his allies' pain, fatigue, and injuries, redistributing the physical toll onto his own body to keep fighters on the front lines.
- Morale Coordination: When his allies' goals and emotions align with his own, the ability can synchronize their movements, effectively acting as an ultimate commander's network.
Why Subaru's Authorities Matter for the Story
Many viewers wonder why Subaru doesn't become a traditional shonen protagonist who blasts enemies with overpowered magic. The narrative design deliberately rejects this path. Subaru's Authorities matter because they reinforce his core identity: he cannot win alone.
Each power mirrors his psychological state and dependence on others. Invisible Providence is weak because he lacks malice; Cor Leonis is powerful only when he cares deeply for the people standing beside him. By tying his progression to conceptual burdens rather than statistical level-ups, author Tappei Nagatsuki ensures that Subaru's victories always feel earned through strategy, emotional vulnerability, and teamwork rather than brute force.
Frequently Asked Questions
Does Subaru control all the Witch Factors?
As the story progresses across the light novels, Subaru gradually attracts multiple Witch Factors, though managing them strains his sanity and physical limits. He doesn't hold all of them simultaneously from the start.
Why are Subaru's powers so much weaker than the Archbishops?
Subaru's mind and soul interpret the Witch Factors differently. Because his primary drive is protecting others rather than selfish domination, his Authorities mutate into support and survival tools rather than weapons of mass destruction.
Can Subaru use Return by Death consciously?
No. Return by Death triggers automatically upon his death, sending him back to a pre-determined checkpoint without his conscious control over when or where that checkpoint updates.
Is Magic separate from Authorities?
Yes. Standard magic relies on gates and external mana absorption (like fire or water elemental affinity), whereas Authorities bypass mana entirely, functioning as direct rule-breaking anomalies tied to Witch Factors.
