**Marye Beelzebub**(*メアリー・ベルゼブブ; Mearī beruzebubu*),previously known as **Marye Purson**(*メアリー・プソン; Mearī Puson*) is one of the current Neo-Great Satans, the wife of Maverick Asmodeus and Irene Dantalion's mother. She's also Nerio Allocer's best friend and Marcenas Lucifer's rival in the High School DxD: Black continuity.

She's one of few surviving devils that fought during the Great Apocalypse, making her a living legend and a hero among her peers. Mary is the Chief Advisor for the Technology Department, Succeeding Ajuka Beelzebub, being also a doctor at the Beelzebub hospital

## Appearance

Marye is described as a a tall, pretty and slender woman with bright green wavy hair with several ribbons wrapped in them, fair skin and equally emerald eyes, wearing a medical coat over an tight leather black jumpsuit and carrying several needles with her. It is noted that she wears a monocle under her right eye after Marcenas almost blinded it during a fight.

## Personality

Marye is usually a very stoic and calm woman, maintaining a professional façade even during normal conversations with her friends and arcquantances. She hates to be disturbed during her job, and even while maintaining her usual demeanor, Zenjirou notes she oozes a rather dangerous and malicious aura even heavier than any other devil's he ever encountered. However, she'll honestly apologize if her small displays of intimidation affect those unrelated to her wrath, showing such affable side also to her patients who she swears to cure.

However, she carries a certain amount of animosoty towards her Childhood friend Marcenas Alastor, and is usually stoically enraged when remembered she lost the position of Lucifer to him. She also hates to be compared to her predecessor Ajuka Beelzebub, and wants to surpass him in order to prove herself the smartest of the two. She won't forgive those who try toi diminish his name or title though, showing some degree of respect for him.

Marye seems to take a liking of Marcenas' daughter and her peerage, saying a kind of those is only born every century.

## History

Marye is the youngest child of the Purson clan, the childhood friend of Nerio Allocer, Merienda Satan and Marcenas Lucifer, who she used to bully due to his Alastor heritage, somewhere before the Great Apocalypse. She was taken under the wing of the Demon Lord of Beelzebub Ajuka due to her massive intelect, in which she then developed the wish to surpass him someday. She fought alongside Maverick, Merienda and Marcenas during the great Apocalypse, and during the reconstruction of the Underworld, fought against the Latter for the position of Lucifer, losing and almost being blinded on her right eye, instead inheriting the position of Beelzebub and Chief Advisor for the Technology Department.

A few years prior the start of the fanfic, she married Maverick as an experiment and had a daughter with him, Irene, who inherited both their signature abilities.

## Powers & Abilities

   **Immense Demonic Power -** Inheriting the title of the demon Lord Beelzebub and being considered a Super Satan, Marye is one of the strongest devils in the Underworld, only under her Rivals Marcenas and Merienda, Rampardos Allocer and Grandmaster Millicas in terms of power, being a mile stronger than the other demon Lords besides them. In fact, if by any reasons she was to be put in a battle position, her presence would be considered an affront against all of the other factions and a declaration of war altogether.
**Venom -** Being a member of the Purson clan, Marye's blood is actually poison, which lethality can vary from anesthesiac to certain death. She uses her poison instead to help her patients at the Beelzebub hospital, rarely using as a form of weapon, altought she uses syringes in order to reach them. While mastering such powers, the lethality of the poison is controlled by and deep proportional to her emotions, and as such, if she's either enraged or deep in thoughts, her skin becomes darker since her poisonous blood becomes deadlier.

* **Poison Rune(ポイズン・ルーン; Poizun rūn) -** A form of poison Marye developed herself for her magical attacks. Marye can create runes with several effects and embed them with poison, creating things such as poisonous fireballs, poisonous ice or even poisonous lightning, which poison anyone attacked by them.
* **Goetia Fetus(悪魔の誕生ゲーテ・フェトゥス, *Gēte feto~usu*)** - Also known as **Birth of the devil**, is another special ability developed by Marye. If by any chance her poisonous blood is unable to create a cure for any kind of venom, for example Albion's **[REDUCE]** venom, Amurokros' Plague Bane or Marcenas' poison, Mary can create from her body a fetus-like child that carries her brain and all the information it has, which them matures and becomes a new Marye. A technique created for escaping strategies, it also enables the new Marye to developed a stronger body against stronger poisons at the cost of some years of her lifespan.

**Specialized Demonic Power**: With the wish to surpass Ajuka someday, Marye developed her own form of specialized demonic magic that uses letters instead of numbers. For being still under development, this form specializes in modification instead of Creation, unlike Ajuka's, and therefore weaker.

* **Ars Lexicon**(戦争の辞典アルスレキシコン, *Arusurekishikon* ) - One of Mary's specialized moves in which she can change the properties of any form of magic or phenomenom that happens on her Vicinity.

**Master Modifier-** While as yet to develop something herself, the other Demon Lords admit that Marye is a master in adapting and motifying anything she touches for the best, as she has immense knowledge about the Evil Pieces, Sacred Gears and others alike.

**Master Healer -** Being a doctor chief at the Beelzebub Hospital and a Purson, Marye has a vast knowledge about medicines and antidotes for any form of patients, as she can cure or help anyone as long as she has a quick look into their data, and even produce some antibiotics herself with her blood.

**Master Marksman -** Marye seems to be also very good with projectiles and have a pretty accurate aim, as she can hit veins with extremely precision against fleeing patients or foes with syringes and nothing else.

## Equipments

### Inventions

Despite not being a proper inventor, Marye has the power to modify and create something completely different out of already existent concepts, which earns her the title as Ajuka's successor:

* **Fairy Pieces**(移転の駒フェアリーピース, *Fearīpīsu*) - Also known as **Piece of Recolocation**, is a special type of Evil Piece any Rook, Bishop or Knight can use once per game in Rating Games. By using it, one of the said pieces can adquire a new special trait from any other piece in order to compensate one of their weaknesses.
