Kamilla

Kamilla is one of the Four Lords of the Monster Realm. She was the only female Dragon prior to becoming a Dark Lord and as such, was treated as a trophy that the Dragon's fought for when selecting their king. This changed when she was taken from the castle of the Dragon King by the second Demon King, Avel.

When Avel made her into a Dark Lord, it triggered a war between Dragon and Dark Lord in which Dragons were the victor after Avel was sealed. Following the end of the Demon King's reign, the world knew peace under the Dragon rulers. However, the peace the Dragons had achieved bored and angered the creator of the world, the Whale God. He had the Dragon species exterminated with an army of Gods.

Kayblis, a fellow member of the Four Lords of the Monster Realm, is in love with her, but she hates him as she was defeated by him and finds his image hideous. She only loves beautiful men and boys and her large number of Apostles are composed of such people. Probably due to the fact that she was the Dragon equivalent of a trophy wife, she is very lazy and has little ambition towards anything. Despite this, she chose to invade Zeth with an army of monsters, just to get away from Kayblis.

Kichikou Rance
Kamilla (translated as Camilla) leads La Seizel and Lei to Leazas to capture Little Princess, but mostly just to get away from Kayblis. She spends most of her time at a mountain hideout playing with beautiful boys and young men that her apostle, Reincock kidnaps for her. Reincock is a femenine crossdresser who is completely obsessed with Kamilla over everything else. Eventually, Kamilla returns to the monster world after Kayblis becomes the King of Monsters but still refuses his affection. Kayblis eventually demands that Kamilla surrender her body to him, but she reacts with hate and states that she would rather die than become his woman. Kayblis then kills her and Reincock in a fit of rage and Silky eventually absorbs her demonic blood soul to try and gain power to defeat Kayblis.

After Silky is defeated by Kayblis, her demonic blood soul is extracted from Kayblis but no mention is made of what Kayblis did with it, if anything.

Rance 6: Fall of Zeth
In the year LP0004, Kamilla led an army against Zeth. Alongside her were fellow Dark Lords Sieg and La Saizel. With the destruction of the mana batteries powering Zeth's Maginot Line, Kamilla was able to invade and conquer most of Zeth. However, this victory was short lived. Sieg and La Saizel were defeated by Rance and the Maginot Line was brought back on line, pushing the army back. Kamilla fought Rance, but due to inference on Abert Safety's behalf, she lost and was sealed in a dungeon beneath Zeth. Whilst sealed, Rance raped her, causing her to hate him.
