Nimue is the second in command of the Seven Deadly Sins and is the Wolf's Sin of Death. After being declared a traitor and branded a murder for the death of Grand Master Zaratros like the rest of the Sins she escaped and travelled keeping on the move to avoid killing innocents with her curse. Her sacred treasure is the Demon Spear, Messorem, and her power/curse is Ankhseram Black Magic. She is also the former second in command to The Ten Commandments and a former member of Stigma. She was promised to the oldest son of the Demon King. Falling in love with his skills and leadership and dedication to whatever held his attention she knew they'd be okay no matter what. So when Meliodas left the Demon clan and asked her to go with him she went. Her punishment was a cursed set by her father for leaving. After being labelled a killer like the rest of the sins for the death of Grand Master Zaratros she fled, separating from the other sins and keeping mostly to herself.
