Byleth (Female) in Dynasty Warriors 9: Empires

Making Female Byleth from Fire Emblem in DW9E

Byleth is the main protagonist in Fire Emblem: Three Houses and a major antagonist/anti-hero in Fire Emblem Warriors: Three Hopes. As an Avatar, their name, gender, and birthday are customizable. Byleth serves as a professor at Garreg Mach Monastery. They possess the mysterious Crest of Flames and can wield the Sword of the Creator.

The name Byleth is a variation of Beleth, a king of Hell. According to Pseudomonarchia Daemonum, Ham, Noah's son, was the first in invoking him after the flood, and wrote a book on mathematics with his help. This alludes to Byleth's nickname "The Ashen Demon" for their emotionless countenance on the battlefield.
