Ragna the Bloodedge's name is derived from "Ragnarök," a Norse term commonly used to describe the end of the world. This could tie into Ragna's ability to channel the Black Beast, which nearly caused the end of the world in BlazBlue's timeline.

It may also be a reference to the legendary Ragnar Lodbrok, a man who slayed the serpent Jörmungandr. This mirrors the relationship between Ragna and series antagonist Yūki Terumi, who has a snake motif for his attacks.
