The Lord of Pride.
After her defiance against god, she was accused of the 'Pride' sin and was banished from the heaven. She's been a fallen angel ever since.
She's also the current leader of the Seven Mortal Sins who's leading the others.
Although she acts arrogant and looks down on people a lot, she is secretly a naive and straight-forward spoiled-girl who can be easily charmed with a simple compliment.
