Mael

Mael is an elite warrior of the Demon Clan, serving directly under the Demon King as the Faith of the Twelve Laws.

As a Demon
Mael is a very tall and muscular man and wears a white longcoat with gold gauntlets and boots. He has silver hair and noticeable facial stubble. He also has the same demonic seal as Sirius and Elderos but unlike Sirius, it is above his left eye similar to Elderos.

After absorbing the Commandment of Love, Mael's appearance remains mostly unchanged except that his forearms and legs are covered in darkness, along with darkness covering his eyes and forehead. Once he absorbs the Commandments of Reticence and Patience, he transforms for a second time with his entire body covered in darkness similar to that of Sirius' Full Demon mode.

As an Angel
Mael has long, curly silver hair with blue eyes. He possesses three sets of angel wings with the first set being larger than the second, and the second set being larger than the third set. He is seen to have a very muscular build. He wears a robe with several buttons along, striped pants and sandals.

After absorbing the Commandment of Purity, Mael undergoes a transformation. He happens to have eight large wings on his back, four being white on the right and four black on the left. He goes on to wear a long full-body dress.

Personality
Mael has a calm, reserved, yet mocking personality. Upon being released from the seal he wishes to rest before acting and when the Twelve Laws realize that they may reclaim their lost magical power by consuming the souls of humans, he chooses to summon some lesser demons instead of having to work herself. Mael also expresses boredom and sarcasm when faced with challenges, showing off his rather apathetic side. He is known to be boastful and cocky during battle. He also seems to look down on humans in general.

7,000 years ago
Mael was one of the Celestial Clan's Seven Archangels and Luciel's younger brother. In his youth, Mael was rejected by his clan because he had the demonic powers of Void Energy.

It was also during this time that he met the fairy Lavender and fell in love with her because of her being the only person besides his brothers who never made fun of him. However, Lavender, who only had eyes for Kilimiester, did not reciprocate his feelings. Despite this, Mael always kept observing her from a distance and told Luciel about his feelings for Lavender.

At one point, Mael confronted the leader of the Black Vanguard, Gardonza when he raided a Sky Temple and showed his far superior strength by effortlessly almost burning him to death until Sirius interfered. The result of their fight it is unknown, given how equal the two seemed to be in raw power

According to Luciel, Mael was at some point killed by one of the Twelve Laws. This, however, was revealed to be a false memory forged by the demons Kilimiester and Gambion. Searching to put an end to the First World War, Kilimiester uses a forbidden spell and reforged Mael's and everyone else's memories of the Archangel, giving him a new identity as the third son of the Demon King, under the same name.

Now a part of the Demon Clan, Mael received the Law of Faith that Sirius abandoned, becoming a member of the Twelve Laws. The supposed death of Mael was so devastating for the Celestial Race, that it forced them to carry out the seal of the Divine Providence. Mael was sealed away by the Celestial Race along with the rest of the Demon Clan, ending the First World War.

Abilities and Equipment
As one of the Seven Archangels, Mael is an extremely powerful angel. Like all members of the Celestial Race, he has wings that grants him the ability of flight.

Despite being initially weak from the beginning, Luciel knew Mael possessed immense potential and would be able to surpass him in the future. Living up to Luciel's beliefs, Mael became the strongest of the Seven Archangels. His older brother, the leader of the Seven Archangels, openly admits that he is not able to match Mael's power. With his very presence alone, he was able to use his power, Sunlight to completely cloud over Gardonza's darkness, the leader of the Black Vanguard, and deal heavy damage on him. Mael is so powerful that after Sirius' betrayal of the Demon Race, to perverse the balance of power, Kilimiester was forced to convert him into a Commandment in order to tilt the power balance of the war in favor of the Demon Race, forcing the Celestial Race to perform the Seal of Divine Providence. His power as the most powerful of the Seven Archangels is far superior to the power he had as a demon, as while he was considerably overwhelmed by the Commandments, upon regaining his memories and power as Mael, he proved capable of fully controlling the Commandments and Disasters in his body. The Commandments inside him also serves as a replacement to the power he possessed. Even after he sustains severe wounds from Deor's beating, he was still able to instantly kill him with his Black Disc and successfully absorbs the Commandment of Purity. At this point, Mael's power skyrockets to being above 200,000 and his magic power alone was sufficient to terrify and cause Task, Malcoma and Maix to sweat, with Lavender going as far as to tell them to run upon feeling Mael's power. After re-obtaining Sunlight, he easily dispels Calyptaro's spell of Darkness and overpowers his attacks after he had increased his power with Solar Flair.

Mael possesses tremendous speed, as shown with his attack, Sun Blitz.

Abilities

 * Main article: Faith


 * Faith: This power allows Mael to use any magical powers, given to him by consenting allies.


 * Reflect Damage: This ability allows Mael to reflect magic attacks aimed at him back at the enemy, but with much greater power; therefore, the stronger the opponent's powers are, the stronger the rebound becomes. He was taught this power by Calypto.

Commandment
Mael was bestowed the Commandment of Faith by the Demon King, meaning that any who show faithlessness in his presence will have their time stolen from them, symbolizing being condemned for their sins.

Elderos
He is often near him and seems to respect him a great deal as his older brother. During the time they were recovering their magic power, he talked to him a lot and without any type of formality despite him being the leader. This proves their friendship and respect they have for each other. When Grimoire wants to slack off and drink, he berates him, stating that Elderos would be furious.

Grimoire
Though they have their disagreements, they are actually very good friends who enjoy each other's company and drinking together. He says he teamed up with him in order to look after him because he cares for him, and after Grimoire is destroyed by Atreus, he is noticeably distraught. During the great First World War, Grimoire protected him without a thought showing he genuinely cares for him as a friend. Mael calls him "Gramps"

Alzareth
Mael and Alzareth are fellow Laws as well as brothers, as they both have been part of the Laws since 7,000 years ago. They seem to have a normal relationship and get along fine. However, when Mael turned against Elderos and the rest of the Laws, trying to steal each and every one, in order to gain enough power to break Lavender's curse, he kills Alzareth, though feeling great sorrow and pain over it.

Sirius
Sirius was the former leader of the Laws, as well as his eldest brother. He looked up to him greatly just as the others did, to the point of considering him the only demon suitable to become the next King. However, after he betrayed them, Mael turned that admiration to disgust, seeing him as worthless and useless. Mael was forced to kill him, on direct orders from the Demon King.

Merlin
Mael, at first, had no interest in Merlin other than his soul due to a desire for regaining his lost power. He found his and Arthur's predicament funny, and attempted to eat his soul in front of both Arthur and Vaun in order to scare them. After Merlin's father sacrifices himself to protect Merlin, he began to hate Mael more due to him being the cause of both his and Arthur's suffering. Merlin later destroys one of his hearts, starting a pure antagonistic relationship between the two.

Jimi
Mael despises Jimi with his entire heart. Ever since he first met the incarnation of the Celestial Lavender, he fell in love with her, only to find out she only had eyes for Kilimiester. For the next seven thousand years, Lavender would be constantly reincarnated, and Mael would fall in love with her, over and over again. While Mael despised Kilimiester, he eventually came to accept him, even gaining his trust and help to break Lavender's Curse.

Atreus
Mael at first had no interest in Atreus and only thought of him as a human who made good liquor. After he revealed his pride form and made destroyed Grimoire, he thought of him as a cocky and arrogant man which only made him want to kill him faster. Not moments later, Atreus launched Mael through a wall and trapped him under a table, leaving him nearly dead due to Atreus' sheer power.
