MARIA (マリア, Maria?) is the Fraxinus AI. After the ship's upgrade to Fraxinus EX, she gains the ability to talk to the crew members.


As the Fraxinus AI, MARIA is responsible for compiling the data options given for Shido's date with each Spirit. After her upgrade, she gains the ability to talk to the crew members and offer her opinion on combat matters. During the final battle with DEM, she was able to gain physical form through Nia's powers.


After being given physical form through Rasiel, MARIA's appearance looks virtually identical to Maria Arusu. She is 158 cm tall, and her three sizes are B84/W58/H85.[5]


As the Fraxinus AI, MARIA has an insightful perspective and delivers her advice in any given scenario when needed. At the same time, she can be remarkably childish and hold grudges against people like Nia Honjo for insulting her. In these cases, she shows a more snarky and vindictive side to herself. Shido notes that this side of her personality makes her more remarkably human than an AI would normally be considered.

MARIA shows considerable interest in the human lifestyle. Within a month of gaining her human form, she keenly observes the interactions between Shido and Kotori, while also voicing an interest to study at high school. Within a year, she begins to have her own possessions funded by a part-time job under Nia, and becomes capable of conducting herself in social gatherings. She also learns how to use hand gestures to imitate the way a human counts, even though as an AI it would be unnecessary for her to do so.



MARIA has always remained within the system of the ship, being the one that compiles the choices during Shido's dates. However, while always lurking behind the scenes, she was unable to communicate with the crew beyond that. Thanks to the upgrade to the Fraxinus EX, MARIA now gained the ability to freely speak to the crew through the communication system.

Powers & Abilities[]

Being the Fraxinus AI, MARIA has complete control over the ship. She is able to control every function on the ship as if they were her own limbs. During times of emergency, she can relinquish control to Kyouhei Kannazuki, allowing the Fraxinus vice-commander control of the ship by using the ship's main Realizer. However, MARIA finds the mere thought of this detestable and would only ever consider it during emergencies when she is too preoccupied with another matter.

After being given a body through Rasiel's power, she gains the ability to duplicate herself and revive continuously like the Nibelcole as long as Nia still has Reiryoku left. After Nia lost her powers, she was able to retain physical form through just the Realizer alone. Her Realizer body is remarkably human-like, being able to consume food and sweat just like a normal human. Each MARIA body is equipped with its own internal Realizer, which means MARIA often likes to summon multiple copies of herself to double-check the accuracy of the main Fraxinus ship's calculations.

Weapons & Equipment[]

Yggd Ramus (世界樹の枝ユグド・ラームス?. lit. "Branch of the World Tree"): An experimental weapon that functions similarly to a Wizard's laser blade. With a metal handle, the blade itself is around 30 cm long and in the twisted shape of a tree branch. MARIA designed it by studying Mukuro's <Michael>. Theoretically, it can be used to separate an Angel from a Spirit, but the gravitational pull between a Spirit and her Angel is just like a satellite revolving around a planet. As such, the measure would only last for an instant at best. However, thanks to the former Spirit girls' affinity for Beast's swords, stabbing Beast with the Yggd Ramus allowed the girls to plunder the swords and use them to temporarily regain their Spirit powers.



  • (To Nia Honjo) "MARIA does not listen to you." [6]
  • (To her viewers) "──Yes, this is super AI Maria. Greetings from above the sky today. How is everyone crawling on the ground getting along?" [7]
