Dunya Musta'sim

Dunya Mustashim (ドゥニヤ・ムスタシム, Duniya.Musutashimu) was a former princess of the Mustashim Kingdom, and a member of Al Sarmen.

Appearance
Dunya is an average sized woman with braided hair and a princess dress on. She usually has her eyes squinted so you can't see her eyes when not in combat. She carries around her weapon and is typically seen with a smile.

Personality
She appears to be a very polite girl, fitting her princess heritage but she can become violent and battle hungry when fighting. She seems to want to prove her worth and cares deeply for her body guard, Isaac. She also holds a deep hatred towards Magnostadt and even as a child she cared a lot about her country.

History
She was the previous Princess of the Mustashim Kingdom, up until 10 years before the start of the story.

Dunya's mother died when Dunya was a child and she was raised by Isaac's mother, so she considered him almost a brother. When she was 13 she was engaged to an archduke of a Mustahim's neighboring country, and she commands Isaac to protect Mustashim as her knight. Soon after, Magnostadt's students began a revolt and took down the King, Dunya's father. Mustashim's royal family was ordered to be eradicated and Isaac died protecting her. In that moment, she decided to curse her fate.

Zagan Arc
Dunya is first introduced posing as a merchant to enter in the dungeon Zagan, with Isaac and Isnan, following Aladdin, Alibaba Saluja, Morgiana and Hakuryuu Ren.

When Aladdin's group gets to know where the treasury is, Dunya and her group make their appearance. Aladdin notices immediately that they're from Al Sarmen and run with his friends to the treasury, where Dunya starts her attack. She is surprised when she sees that Aladdin's Bolg is very resistant, and states that they're going to fight seriously. She presents herself to Aladdin and Alibaba, and asks them to let her conquer Zagan. When they refuse, she sticks her Dark Metal Vessel, Al-Kaus, and transforms into a Dark Djinn.

She gathers sand around her hands and starts a fight with Aladdin, while Isaac fights against Alibaba. When she easily destroys Aladdin's Bolg he realises that she's strong. She repeatedly destroys Aladdin's Bolg and doesn't seem damaged by Aladdin's magoi shots, but gradually gets weaker because she runs out of magoi. She's defeated, but then she remembers her promise to Isaac and stands up again, changing her form to a Dark Djinn Equip.

Dunya restarts the fight, changing the shape of her weapon multiple times, giving trouble to Alibaba and Aladdin. With her ability, gets up Isaac from the floor, who fights again against Alibaba. Isnan makes them stronger with his lightning magic. Dunya invokes her Extreme Magic, Rea Baldo, and thousands of Dark colored swords rain from the sky. After the execution of her magic, she realises that she's been fooled and her attack didn't hit her enemies. Isaac tries to protect her, but he's disintegrated into dust as he was dead since the begining and only Dunya's power maintained him up. Then she collapses and falls into depravity, trying to kill Aladdin and Alibaba with her now-useless Dark Metal Vessel, but Aladdin uses Wisdom of Solomon to know her story. Aladdin searches Isaac's Rukh who finally gives her peace.

Second Sindria Arc
After what happened to Zagan's Dungeon, Dunya was brought in a bad state to Sindria. First, she didn't want to talk to anyone, and less to Yamuraiha or some other magician, but she befriended Aladdin. After some days, she became worse and finally passed away.

Abilities
She uses Black Rukh to fight rather than the normal white Rukh. She uses her Dark Metal Vessel to use Earth Magic with her small spear like weapon.

Dark Djinn
When she impales herself with her weapon, Black Rukh starts to surround and transform her into a Black Djinn. In this state she is a lot more powerful (though it is mentioned that it takes a lot more Magoi than normal) and is able to use tremendous force.

Dark Djinn Equip
Extreme Magic
 * Rea Baldo (Unlimited Sword Dance Array)
 * When Dunya uses her extreme magic the giant metal vessel symbol appears in the air above her. The symbol starts to be covered in a Dark aura until it completely overcomes the symbol. When the symbol is completely covered thousands of Dark colored swords rain from the sky, completely covering the opponent.

Dark Metal Vessel
Al-Kaus (Black Magnet Spear)
 * She usually uses her Dark Metal Vessel to use magnetism to collect sand and from the ground. She can change the shape of the spear to any weapon she chooses, as long as she collects enough sand around it. She can summon earth spikes from the ground.


 * Rock Dragons
 * With the power of her Dark Metal Vessel, she is able to create up to three dragon heads to attack at once.

Isaac
Isaac was her Knight 10 years ago, but was killed while protecting her from a coup de tat forces right in front of her

Aladdin
Aladdin saved her from hating herself for the death of Isaac, and stopped her from cursing her Fate, which causes her rukh to become white again. they be friended each other in no time, but due of the side effects of turning into a Black Djinn, her body got weaker and weaker until she eventually died, turning into a metal coal just like Kassim.

Trivia

 * Her character is based off of 'One Thousand and One Nights' as Scheherazade's sister.
 * Her given name "Dunya" is derived from Arabic دُنيا‎ Dunyaa, meaning "world". Her surname "Mustashim" is derived from Arabic مُستَعصِم Musta3ṣim (also written as "Musta'sim" in more common, but less precise transcription), an adjective describing one whom exercises restraint in face of temptation.
