Mira Kudan (久壇 未良), (also known as Sarah Miller) is a red-haired girl that Sousuke Sagara saved during a mission in Khabarovsk, The Soviet Union.
It is later revealed that she is a Whispered and is rehabilitated by Mithril, who she joins in a Research and Development role.
Biography
Mira was captured by the KGB through Amalgam influence and subjected to extensive testing for Whispered capability at a special facility in Siberia. The testing involved the heavy use of drugs and psychological methods, which took a heavy toll on her mental state. Chewing her fingernails became the only way she could generate any sense of feeling.
A Mithril intelligence agent sent to infiltrate and investigate the facility saw her condition and abandoned his original mission in an attempt rescue her, and managed to get her and a disk containing Whispered information out of the facility before the vehicle they were travelling in was destroyed by a pursuing helicopter, killing the agent and throwing her clear of the wreckage.
Before she could be recaptured, the Mithril SRT team was able to complete her rescue with a squad of M9's under cover of ECS, in a skirmish where Sousuke destroyed the pursing helicopter.
Mithril then assisted her recovery from the KGB testing program in secret. By her own admission, the trauma of the testing never fully left her, however she was able to contribute to the Mithril's R&D division.
After the battle at Jindai High School, she was able to re-use the ARX-7's Lambda Driver and Artificial Intelligence "Al" that were salvaged by Wraith into a new Arm Slave design known as the ARX-8 Laevatein at a secret location in Alaska, alongside Wraith and Gavin Hunter. The new AS design, notably its armament, was predominantly shaped by Mira in collaboration with the AI system to suit Sousuke's combat style.
It is also shown that she is an acquaintance of fellow Whispered, Nami.
Later, she is relocated by Hunter to a secret safehouse where she, presumably, lives out a normal life in peace and calm, regularly maintaining contact with Sousuke via email. For all that he did for her, she has feelings for him although she recognises it would make things worse for Teletha Testarossa and Kaname Chidori, so she puts them aside.
"You are the one I owe my life to, and thus my heart is yours (though if you asked me to, I would do anything, but then Teresa-san or Chidori-san would probably kill me, so I will abstain.)"
Before his final battle she sends him a memory card via Michel Lemon, that has a copy of a video his classmates uploaded wishing him and Kaname a safe return to school.
As a Whispered, she is aware of Leonard Testarossa's final plans for the world, and Tessa's opposition to it. While more partial to Leonard's ideology, she is happy to spectate and let things play out.
