Strategy
Almost all her attacks auto hit, so evasion wont help at all. On top of that, all the Holy based attacks can inflict ascension, bypassing any deflectors you have set up. Therefore, one should bring a team resistant to both holy and ascension. If you can, since the holy elemental attacks take mana to use, draining her mana will waste her turn if she tries using them, leaving only 4 moves she can use out of her 10. Draining her mana also prevents Zero Shift, preventing her from dispelling your useful buffs. As for attacking her, she's weak to pleasure, dark and sonic, of which pleasure should the one you should have the most of.

Evaluation
"Hello, this is Ilias from F22643. Which world's Luka are you? Sonya Mazda seems to be of the Holy element. She uses various elemental attacks and she is hard to deal with. She is strong against Fire, Ice and Thunder, but Pleasure is her weakness. Seems like she possesses the same attributes as an angel. Status ailments rarely affect her. I guess there's no choice but to fight her without them... End of transmission, Luka from another world. This is the last message from F22643. Farewell, and keep on fighting Luka, wherever you are. From F22643, this is my last goodbye."

LoC Strategy
Fight her like you would deal with any of the Labyrinth of Chaos bosses:
 * Always have Vicarious Clara active or another barrier active. One of her attack hit 4 random times, so stacking buffs is recommended.
 * Anti-Death song (Fox Geisha only) is needed to counter the ascension effect on her holy attacks.
 * She possess a buff increasing her agility and evasion, and another one making her resistant to pleasure. Dispel is recommended to stay able to attack her.
 * She also possess a Freeze attack, which can be countered with the Resist Freeze ability owned by Sea Palace Maikos, making them useful. Additionally, she can be slowed/stopped by the Time Warp Dance and her resistances can be debuffed by the Sea Palace Maiko’s skills.
 * Finally, she has a skill which inflicts a single target Shock, that can be resisted by the Battle Master Resist Shock ability, allowing you to keep your damage output.

Overall, her greatest strengths come from her extremely high resistances, making her immune to most damaging attacks until debuffed.

Trivia

 * Nothing is confirmed about her in Part 1, since she only appears in the Labyrinth of Chaos. Like her counterpart, the left half of her face is abnormal (hidden).
 * Her name makes a reference to Ahura Mazda which is the Avestan name for the creator and sole God of Zoroastrianism, the old Mede and Persian religion. Ahura Mazda is described as the highest spirit of worship in Zoroastrianism, along with being the first and most frequently invoked spirit in the Yasna.
 * The literal meaning of the word Mazda is wisdom.
