Lucifer

Lucifer (ルシファー) is advanced-level furniture created by Beatrice. Lucifer is the oldest of the Seven Stakes of Purgatory and therefore their leader. Because of this she claims to be the strongest of the sisters, but she's secretly aware that she's actually the least talented. However, she has always acted arrogantly in an attempt to hide this fact from the others. Her greatest fear is that her sisters would sneer at her if they ever found out.

Background
Sayo Yasuda created the character of Lucifer based off of Runon, a servant she worked with at the Fukuin House.

Appearance
Like the other Stakes of Purgatory, Lucifer wears a black and red outfit with a red jacket and pink tie. Unlike her sisters, Lucifer has long black hair that covers her back.

Personality
Fitting with her associated sin, Lucifer is extremely prideful and highly insecure about being the weakest of the Seven Stakes of Purgatory. She will often showboat during battles and is reluctant to ask for help. Despite this, she has a firm position as leader of the Seven Stakes of Purgatory and maintains control over her sisters during serious situations.

Banquet of the Golden Witch
Lucifer is called upon by Beatrice to kill Kanon as part of the first twilight. However, Beatrice offers to spare Kanon and his loved ones if he can defeat the Seven Stakes of Purgatory. Kanon successfully defeats Lucifer in one-on-one combat but fails to defeat the other sisters.

End of the Golden Witch
Lucifer kills Hideyoshi Ushiromiya in the second twilight.

Dawn of the Golden Witch
BATTLER has Lucifer kill Natsuhi Ushiromiya in order to save the weakened Chick Beatrice.
