Lili

Lili (リリ) was Delta and Zeta's ancestor and one of the Three Heroes who defeated the demon Diablos, known as the "Beastkin Hero". In reality, however, she was a pawn of the Cult of Diablos, being a survivor of their experiments, tasked with defeating the demon of their own ends.

Appearance
She shares a resemblance with Zeta in terms of appearance.

Personality
It's unknown what her real personality was, but it is implies that she has a sense of justice as she believed defeating Diablos would save the world.

However after being sealed inside the Sanctuary for centuries, she had been reduced to an emotionless state, possibly forced to serve the Cult of Diablos.

Synopsis
Centuries ago, originally Lili was a normal beastkin until she was kidnapped by the Cult of Diablos, to perform an experiment with her and all the other children, boys and girls alike they had kidnapped and collected to implant Diablos Cells, in an attempt to create powerful soldiers to fight the Demon King Diablos. The experiments resulted in almost failure, since most of the children ended up dying, and a small group of girls survived because they could not tolerate the blood of the demon in their veins.

Luckily for the Cult, 3 girls survived the experiments, whom turned out to be an Beastkin, a Elf and a Human, Lili was one of the other 2 surviving individuals. The cult carried out more experiments to make them stronger and powerful, creating weapons and equipment for them so that when they are adults and ready, they would go to fight the Demon King Diablos.

It was historically recorded that years later, Lili already prepared along with the other two heroes, which is the Elf hero Olivier and Human Hero (Freya; WN Only) went to exterminate the demon Diablos by order of the Cult, which resulted in the demon's defeat. But then, she and the other two heroes were cursed by Diablos so that their descendants would be possessed with rotten bodies.

However, the truth was, Lili was one of few people who are compatible with Diablos Cells. Hence, she was tasked by the Cult to gather more cells in order to produce more Tears of Diablos. Moreover, the Cult has already manipulated historical records globally and misgendered Lili as a man, so that no one would be able to find out the real facts and try to investigate the truth.
