Lili

Lili (リリ) was the Beastkin hero, one of the Three Heroes who defeated the demon Diabolos.

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 Diabolos 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 Diabolos.

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 Diabolos cells, in an attempt to create powerful soldiers to fight the Demon King Diabolos. 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.

But luckily for the Cult, 3 girls had survived which turned out to be an Beastkin, a Elf and a Human, Lili was one of the other 2 individuals, the cult carried out more experiments to make them strong and powerful, creating weapons and equipment for them so that when they are adults and ready, they would go to fight the Demon King Diabolos.

Years later, Lili already prepared along with the other two, which is the Elf hero Olivier and Human Hero (Freya; WN Only) went to exterminate the demon Diabolos by order of the Cult, which resulted in the demon's defeat. Then, she was cursed by Diabolos so that her descendants would be possessed with rotten bodies, along with the descendants of the others two heroes.

However, the truth was, Lili was one of few people who are compatible with Diablos's cell. She was tasked by the Order to gather more Diabolos cells. Then, Lili is treated like a man, because the Cult twisted history globally, so that no one would know the truth of everything or investigate it.

Powers & Abilities
Being one of the 3 that survived of the Cult of Diablos' experiments with the implanted cells of the Demon Diablos, it can be assumed that Lili was considerably the most powerful individual in the Heroes group, making her the most lethal weapon of the Cult.
