Bone Bows Before the Steel

Bone Bows Before the Steel is a wicked God-Weapon - a huge sickle (or scythe, depending on your POV) that among other things has a tendency to set its´ wielder´s enemies on fire! Iron Seraph learned this the hard way when he faced its´ nameless owner (who then fought beside the Scarlet Tiger students in an all-out street brawl between a coalition of Dragons and Tigers on one side and a Black Crane warparty on the other) - first, the scythe smashed his ancestral sword Wind-cutting Edge to pieces, then he was lit on fir and almost dispatched!

Recently, the nameless one was defeated by Bladed Soul of the Black Crow Brigade, who took the God-Weapon from him and seemed to absorb it into her own body! (At the end of S01E06!).
