Mia Cyrus

Mia Cyrus (ミーアー・サイラス) was a Magical Girl with the designation "Just Cause" (ジャスト・コーズ). She is part of the Magical Five, who survived the Distonian War, and came to work for the CIA afterward.

She dies in a suicide attack in chapter 60 to take out Brigadier.

Personality
Mia is a bit brash, standoffish, and vulgar, but she is a strong fighter who strives to save people and make the world a better place. She once said that she wasn't chosen because she was strong, but she became strong because she was chosen, which hints at her strong work ethic. Mia also is a bit child-like, delegating the written report in If this Battle Ever Ends to her assistant Julia and dozing off, as well as getting excited over a slushie in Wish Upon a Star. She also revealed her identity to the public, being the only Magical Girl that has ever done that.

War Nurse Kurumi
Mia cites Kurumi as the only one of the Magical Five she could truly trust, implying that they have a strong relationship.

Phoenix Tamara
Mia and Tamara have a little bit of a passive-aggressive rivalry, where Mia calls Tamara "Russian" ("Ruskie" in the manga translation, "Russia" in the English dub) and Tamara calls Mia "Texas Girl" ("Texas" in the English dub). Netherless, they work well together.

Shantoulon Peipei
It seems that Mia cares a lot for Peipei, as she helps her and Astrologer get a place in San Francisco with her at the end of the Ukraine arc.

Chevalier Francine
While Mia didn't care for Francine's perverse manner, she respected her as a leader/Magical Girl, and even found herself missing her a bit in episode 12.

In chapter 56, it was revealed that the two were in a relationship during the Distonian War.

Julia
Mia jokes around a lot around Julia and slacks off, making their relationship seem a little on the wacky side.

Abilities & Powers
As an Magical Girl, Mia possesses magical perception blocking that allows no one she knows in real life to recognize her, a reactive magical shield to protect herself from attacks, and the finishing move 'Magical Calorie Roll-Up'.

Mia's magical girl weapon is a derringer, which can transform into different kinds of guns.
