Sybil

**Sybil**「シビル」 is an elite warrior of the Demon Race, serving directly under the Demon King as the **Faith** of the Ten Commandments.

When Sybil was born being the daughter of a demon mother and psychic father of a notorious psychic group known as the "The Travelers" and was lied to when they told that her mother died in a fire and that she was a pure psychic but her father regretted never telling her so when she turned 23 he finally told her the truth. She was so angry that it triggered her immense power of demon that completely amplified her psychic powers that enslaved every Traveler there and then she killed them. The Demon King felt the sensation and told Zeldrith to retrieve and just as the Demon King expected she accepted and he bestowed her the gift as a creature he specifically designed for her and that was a siren. Being one, enhanced her psychic power 20 folds making her psychic powers range from vast areas and be able to even read and control the smallest and/or complicated brains. But soon at some point, she was chosen as the **Faith** of the Ten Commandments by the Demon King himself.

After Ludociel imprisoned a horde of demons as bait, the Ten Commandments Sybil, Monspeet, Derieri and Galand, along with Fraudrin, led an army of demons to the Fairy King's Forest. They were confronted by Elizabeth, who wanted to stop the fighting between the Goddess and Demon Clan. While she talked with the demons, Ludociel revealed the giant **Ark** holding the captured demons. Sybil noted that most of them are civilians before Ludociel killed the prisoners. Angered, the demons attacked.

The Archangels Sariel and Tarmiel destroyed most of the army with an **Omega Ark** but the Ten Commandments survived. While the others fought the Archangels, Sybil flew to the Light of Grace where Gowther had taken control of Nerobasta. After reporting the situation, annoyed that Gowther read her thoughts, Sybil is taken by the manipulated Nerobasta to the gate to the Celestial Realm.

Sybil corrupted the gate to the Celestial Realm, preparing it to connect to the Demon Realm instead. However, Gowther tricked her into connecting it to the Demon Realm's prison, freeing the real Gowther. Furious at being manipulated, Sybil's head is grabbed by the real Gowther and immobilized her with his magic. Sybil recriminates that he dared to leave his prison without the consent of the Demon King, leading Gowther to reveal that he has no interest in the Holy War. Later forces her to open a portal to be reunited with the doll Gowther.

Later Sybil rejoices when Zeldris arrives to go after the magician Gowther.

Along with the rest of the Demon Clan, Sybil was sealed away by the Goddess Clan after losing the Ancient War against the Four Races (Human, Fairy, Giant, and Goddess Clans).

Like all members of the Demon Clan, she is able to utilize the mysterious jet-black matter as shown forming wings for flight. she uses it to battle in close-combat as seen in her battle against Ban. She can also use it envelop herself as a protective barrier of sorts and wrap it around her self to shield from strong attacks such as Ban's Fox Hunt technique.
