Tyrfing

Lore & Background

In the Eddas and sagas of Norse myth, Tyrfing is a sword forged by dwarven smiths and cursed at the moment of its creation. It was given to the hero Sigmund, passed to his son Sinfjötli, and ultimately claimed by Sigmund's grandson. The curse is absolute: the sword never remains sheathed, it kills those who wield it, and it sows discord among those who possess it. It is a blade that demands blood and delivers only ruin, a fitting instrument for a world that values strength above all else.

Record of Ragnarok transplants this mythic artifact into the tournament arena, where Loki—god of lies, fire, and the spaces between—claims Tyrfing as his shingu. For Loki, the sword's curse is not a burden but an extension of his nature. Where other gods wield their divine weapons with solemn purpose, Loki wields Tyrfing with a grin, treating the blade's malice as a punchline and its endless hunger as a conversation partner. The sword's refusal to rest mirrors Loki's refusal to be still, to be bound, to be anything other than chaos given a shape.

The 9th round frames Tyrfing's story as a test of whether a cursed object can be redirected. Spartacus, a slave who rose to lead an army of the downtrodden, represents the very thing Tyrfing's curse was meant to destroy: the idea that a person can break free of the fate written for them. Loki, wielding the blade that has killed every hero who held it, must confront whether his own mischief can be something other than destruction.

In Their Own Story

The arena floor was still warm from the previous round's lightning when Loki stepped onto the blood-soaked stone. He did not walk so much as drift, his long coat trailing like smoke, a lazy smile already stretched across his face. In his hand, Tyrfing hummed—a low, almost musical vibration that made the air taste of iron and old grudges. The sword had been sheathed for precisely four seconds before it began to sing again, its edge drinking the moisture from the air, its eye fixed on Spartacus with the patience of a thing that had killed kings.

"You know," Loki murmured, more to the blade than to the crowd of gods watching from the sky, "I've killed so many heroes with you. They all had the same look. Like the world owed them something." He turned the sword once, letting the cursed light catch the edge. "I never had that look. I just wanted to see what would happen if I broke the rules for fun."

Spartacus raised his chain and his gladius. No smile. No quip. Just the quiet, grinding resolve of a man who had already been dead once and chosen to come back. Loki's grin widened.

"Oh, this is going to be lovely."

Tyrfing left its sheath.

Reader's Guide

Tyrfing is the divine weapon (shingu) of Loki, the Norse trickster god, in Record of Ragnarok. Its name and nature derive from the cursed sword of Norse mythology, a blade forged by dwarves that brings death and discord to every wielder and never remains sheathed.

In the manga, Loki wields Tyrfing as a longsword in the 9th round against Spartacus. In combat, it functions as both a physical cutting weapon and a vessel for Loki's divine magic. The sword's curse manifests as a persistent, corrosive effect on those it strikes—wounds that resist healing and a binding malice that saps the opponent's will. Loki also uses it as a conduit for his shape-shifting and illusion-based tricks, channeling his divine energy through the blade to create misdirection and psychological pressure.

The stated cost is twofold. First, the sword's curse is not fully under Loki's control; it demands blood and can turn against its wielder, as it did in the original myths. Second, the energy required to sustain the curse's effects in an arena of gods is enormous, meaning prolonged combat drains Loki significantly.

In terms of matchups, Tyrfing's curse-based damage is particularly effective against opponents who rely on rapid regeneration or physical endurance, as the wound resists normal healing. However, an opponent with overwhelming willpower or a counter-curse (as Spartacus's unbreakable resolve represents) can blunt the blade's psychological and binding effects. Conversely, Tyrfing struggles against opponents who can negate divine energy entirely or who fight from a range that prevents the sword's close-range curse from taking hold.

Did You Know?

• In the original Norse sagas, Tyrfing's curse was so potent that it killed Sigmund, Sinfjötli, and Sigmund's grandson in succession—three generations of heroes undone by a single blade.
• Loki is the only Aesir god in Record of Ragnarok whose divine weapon is a sword rather than a hammer, staff, or ranged implement, reflecting his role as the god of close, personal, and chaotic conflict.
• The sword's mythological property of never remaining sheathed is played for both tension and humor in the manga, with Loki treating the blade's restlessness as an annoying but endearing habit.
• Spartacus, Tyrfing's 9th-round opponent, is notable in the series as a fighter whose power set is almost entirely physical and will-based, making him a natural foil to a weapon whose strength is magical and psychological
