サタン

Representing the demon Satan and the corresponding sin of wrath, she is the third eldest of the Stakes of Purgatory. She is easily angered and speaks with scornful inflection, making her the most feared out of the sisters, including by the sisters themselves. Since people are too afraid to talk back at her, she often becomes lonely. She often tries to intentionally anger her sisters so they can be angry with her, but to no avail. Satan's appearance is a girl with short, curly pale hair.
