Melascula

is an elite warrior of the Demon Clan, serving directly under the Demon King as the Faith of the Ten Commandments.

Appearance
Merascylla is a dainty woman with long, pink hair. She wears a sleeveless leotard with a pink bow on the choker. She also wears long, pink stockings. She is constantly cloaked in shroud of her own darkness.

Personality
Merasylla has a calm, yet mocking personality. Upon being released from the seal she wishes to rest before acting and when the Ten Commandments realize that they may reclaim their lost magical power by consuming the souls of humans, she chooses to summon some lesser demons instead of having to work themselves. She also seems to look down on humans, in general.

3,000 years ago
Along with the rest of the Demon Clan, Merascylla was sealed away by the Goddess Clan after losing the Ancient War against the Four Races (Human, Fairy, Giant and Goddess Clans).

Current arc
After Hendrickson manages to remove the seal, Merascylla and the rest of her fellow Demon Clan members appear before the terrified former Great Holy Knight and Fraudrin in Dreyfus' body with Zeldris utters Meliodas' name as if he knew him. After being informed by Fraudrin of the current events in Britannia, Zeldris suggests that they should head for Edinburgh Hill for recuperation of their severely drained magical powers, on which everyone agrees. They leave Zhuhur Valley by flight, leaving a terrified Hendrickson.

Arriving at Edinburgh Castle, Derrierie and her fellow Ten Commandments find it in ruins and conclude that a powerful magical implosion caused the destruction of the castle; they also find a large hole, which they link to Meliodas. Later on, the Commandments continue to rest and recover their magical power through the souls of humans they devour, whereas Merascylla summons a Red Demon and Gray Demon to collect souls for them. These two are stopped by the three misfits and Hendrickson. She is shocked when she senses Meliodas regain his full power at Istar.

When Meliodas appears, thanks to Merlin's teleportation magic, she along with the other Commandments, except Galan, are surprised to see him. She watches as Melodias defeats Galan in five seconds and he warns Zeldris that the Seven Deadly Sins would defeat the Ten Commandments with everything they've got. In response, Zeldris and Fraudrin attack Meliodas from both sides, but he is teleported back to Istar. Galan is angered and humiliated by his defeat at the hands of the "Accursed Demon." Merascylla appears next to Galan, who is contemplating his revenge, and states that he could not beat Meliodas as he was.

Afterword, Zeldris orders them to split up and move across the land to regain their magic faster. Upon hearing this order, Merascylla splits off with Galan. It is later shown that she is calling back the souls of the dead to use as her own army of Zombies to wipe out the living humans. Upon sensing that one of the souls she revived was resisting her magic, she and Galan decide to check it out and encounter Ban of the Seven Deadly Sins, who states he will kill them.

Abilities and Equipment
Like all members of the Demon Clan, Merascylla is able to utilizing the mysterious jet-black matter as shown forming wings for flight and as a member of the Ten Commandments, she is exceptionally powerful. Her aura, combined with the other commandment's, is so powerful that it made the normally calm Hendrickson sweat in fear by their mere presence.

Commandment
Merascylla was bestowed the Commandment of by the Demon King, meaning that any who show faithlessness in her presence will have their eyes set ablaze.

Abilities

 * Merascylla is able to use her cloak of darkness to form a portal to summon lesser demons to do her bidding.
 * A forbidden spell that amplifies the lingering affection and regrets of the dead. It gives life to rage that would otherwise have no outlet and calls them back to the world of the living. If the dead resists their rage and their grudge disappears, death awaits them once more.
 * Merascylla envelops her opponent in darkness, trapping them within a pitch black sphere.

Current Arc

 * Ban vs. Galan & Merascylla: Indecisive

Trivia

 * Merascylla's "Faith" ability may be based on the first/second commandment of the Ten Commandments: "Thou shalt have no other have no other gods before me" In that the commandment dictates unwavering faith towards the one true god with threat of severe punishment, in this instance, if a person's faith towards anything they hold dear wavers, they will be also be severely punished (in this case by having their eyes burnt out).
