Svafrlami(スウァフルラーメ suuafururāme): is the magical weapon of Nagisa Suzushino that takes the form of a holy/demonic sword.
When not released, Svafrlami appears as a large sword covered in a black iron sheath, when released its black casing shatters and its appearance is that of a sword with a golden emerald encrusted hilt white a white blade with eriting etched into it.
Some time before the current events of the story, Nagisa aquired an OOPArts that manifested into Svaflami.
- The law that applies to Svafrlami is that victory is assured for whomever wields the sword, but after it (Tyrfing) is used a number of three times the sword will be destroyed along with the wielder.
- Tyrfing (黄金色の誓約(ティルヴィング) tiruvingu; Japanese for "Golden Pledge" ): Nagisa takes a stance, wielding her sword with both hands. After a charging period, she slashes the sword at her opponent, releasing a golden wave of magical energy that cut through everything. While the conceptual slash is destructive, it strains the user greatly, and Nagisa cannot use it more than three times, or she will disappear.
- Overload Tyrfing (未だ果てぬ黄金色の聖約(オーバーロード・ティルヴィング) ōbārōdo tiruvuingu; English for "Overloaded Tyrfing", Japanese for "Unchanged Golden Pledge"):" As used in her battle against Sakura, once "Achillies Paradox" has been activated due to the large amount of energy it supplies, Nagisa holds her sword to the sky and swings it, though it appears to have been swung once it has actually been swung three times in an instant. This blow is so powerful it is capable of killing a god and would be able to counter Sakura's "Duel Laevateinn".
- Though it has a the appearance of a holy sword, whether it is released or not, Svaflami is still considered to be a demonic sword and a weapon capable of the ultimate destruction.
