Lady Sword is the angel of vengeance. Once, during a great battle, she was betrayed by angels and people who fought with demons. They left her right in the middle of a fight. There remains only a two-handed sword from a firearm. In this carnage, she lost her right hand and eye and miraculously escaped death. Since then, everyone who met Lady Sword was doomed to death, and those who managed to escape will forever remember this smell of blood and gunpowder.
