Carmilla Carmine

Carmilla Carmine is a demon and one of the Overlords. She is also the main dealer of angelic weapons.
Carmilla is a ballerina, both in life and in death. She wears pointe shoes, but not ordinary ones. Her pointe shoes are made of angel steel.
Angel steel is the only metal capable of killing any kind of creature, be it demons or angels. Carmilla's workers collect the angel weapons left over from the annual exterminations, melt some down, and create new weapons.
Carmilla has two daughters, Odette and Clara. When angels attacked them on the day of the extermination, Carmilla killed an angel to protect her daughters. She became the first person to kill an angel.
The Day of Extermination is the only day of the year when angels descend and kill sinners, leaving the fiends of hell alone. After the last extermination, when Carmilla killed an angel with her angelic ballet shoes, the exterminations were cut in half. Now they are held twice a year.
Carmilla Carmine is one of the main Overlords who leads their council.
Besides her two daughters, she has a friend, Zestial, who is the oldest overlord in hell. They trust each other and are basically very good, old friends.
Carmila Carmine is a professional in many fields, although she sometimes loses her temper, especially when Zestial is insulted or her family is in danger. This is in contrast to Zestial, who appears calm and unperturbed. Zestial claims that Carmila almost never loses her temper, indicating that she is calm and level-headed in non-confrontational situations.

She cares for her daughters and Zestial, willing to do anything to protect them, even if it means killing an exorcist, knowing all sorts of disastrous consequences for doing so. She wants to avoid violence and war, but at the same time will do everything she can to protect her loved ones. She even refused to help Vaggie in the war against the exorcists because of the possible consequences it could have on her family.
