Three Heroes

The Three Heroes (三人の英雄) are the three legendary warriors who once saved the world from the Demon King Diablos.

History
Long ago, the Cult of Diablos kidnapped orphans without relatives to implant and collect Diablos Cells, in an attempt to create powerful soldiers to fight the Demon King Aurora (Diablos). The experiments resulted in almost failure, since most of the children ended up dying, but a small number of subjects.

Luckily for the Cult of Diablos, three girls survived the experiments. They are Olivier the Elf, Lili the Beastkin, and Freya (Web Novel character, unconfirmed), the Human. The cult carried out more experiments to make them stronger and powerful, creating weapons and equipment for them so that when they were adults and ready, they would go fight the Demon King Diablos.

It was historically recorded that years later, the Three Heroes went to exterminate the demon Diablos by order of the Cult, which resulted in the demon's defeat. During the battle, Olivier managed to cut off the demon's left arm with her sword, which was then sealed in the Sanctuary. In the end, she and the other two heroes were cursed by Diablos so that their descendants would be possessed with rotten bodies.

However, the truth was, Three Heroes were the people who are compatible with the cells. Hence, they was tasked by the Cult to gather more Diablos Cells in order to produce more Tears of Diablos.

Trivia

 * All of the Three Heroes descendants to have at least some extent, as "Demon Possession" is actually due to the Three Heroes having been implanted with cells from Diablos by the Cult, with this mutative 'curse' afflicting their female descendants.
 * The names of the Three Heroes that have been revealed so far are the names that can be used in unisex, as their names is generally sound masculine and rarely feminine. Therefore, this is the Cult of Diablos's way of manipulating the world into thinking that all three heroes are considered male rather than female, except for Shadow Garden.
