Balmung: Phantasmal Greatsword, Felling of the Sky Demon (幻想大剣・天魔失墜, Barumunku: Gensō Daiken, Tenma Shittsui?) is a two-handed, golden greatsword with a green jewel embedded in the hilt that boasts a magnificence and enormity possible only for weapons tended to by inhuman hands. it is the holy sword of the Nibelungs, used to slay Fafnir. Upon chanting "-- O sword, Let thee be filled.", he holds it above his head and it begins to glow with an orange light. The twilight swells around the sword and it is released as a flash of light, a surging wave with the simple purpose of destruction. Compared to the straight line released by Clarent Blood Arthur, it releases a wave of twilight in a semicircle that is centered around him.
