*Melascula is an elite warrior of the Demon Clan, serving directly under the Demon King as the Faith of the Ten Commandments. After being empowered by King Arthur she took on the name Chaos Melascula. Later, would end up merging with Chaos Galand into the monster Melagaland.

As Melascula was a snake that bathed in the miasma of the Demon World to gain her demonic powers, she can transform at will into her original giant hooded snake form, which possesses great strength and endurance as she managed to easily hold down Ban with her mouth alone and endured attacks from the other members of the demon clan.

Melascula is a young woman with long, pink hair. She wears a sleeveless white leotard with horizontal and vertical lines in the middle and on top her breast. She also wears a pink bow on the choker. She wears long, pink stockings with white ornaments going around each stocking at the thigh.

She is constantly cloaked in a shroud of her own darkness. Though not readily apparent, she also has an abnormally long tongue accompanied by the enlargement of her mouth.

After Ludociel imprisoned a horde of demons as bait, the Ten Commandments Melascula, 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. Melascula 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, Melascula flew to the Light of Grace where Gowther had taken control of Nerobasta.

After reporting the situation, annoyed that Gowther read her thoughts, Melascula is taken by the manipulated Nerobasta to the gate to the Celestial Realm.*
