Madoka Orimura

Madoka Orimura also known as M is one of the main antagonist from the Infinite Stratos anime and light novels.

Madoka is a member of the Phantom Task. Madoka is younger twin sister of Ichika Orimura and younger sister of Chifuyu Orimura.

In the Heroes Coalition fics, Madoka is a member of the Dark Forces and is part of the Miyamoto Faction.

Appearance
In the Light Novel, she is described to have almost the same face and body features as Chifuyu Orimura in her high school days. Compared to Chifuyu and Ichika, Madoka appears to have a petite body and has the same hairstyle as her older sister. She usually wears a yellow locket around her neck that has a picture of Chifuyu Orimura in it. Her IS suit is uniquely different from other IS pilots, as it's black and white down the middle and reveals the side of her body.

Personality
Her personality is almost the exact opposite of Ichika's. She is cold-blooded, quiet, and prideful, always looking down on almost everybody but doesn't say it out loud. So far in the Light Novel series, she only has one goal and that is to kill Chifuyu Orimura, and on occasions she plans to also kill Ichika Orimura.

In battle, Madoka is very cool-headed and sadistic, as she would both mock and at times toy with her opponents. She complains about how weak the guards are compared to her in the first episode of the second season. She also doesn't seem to care who she hurts when it comes to getting what she wants. Likewise, she finds it more bothering to not kill someone in her way than it is to just kill them. But when ordered to or when she can't afford to, she'll simply try to deal with them as fast as she could.

Abilities
She pilots the Silent Zephyrs, which was based off of Cecilia Alcott's Blue Tears and was stolen from England. It appears to be more advanced than its successor IS. She has shown to be a extremely skilled fighter; having been able to overpowered IS Representatives multiple times easily. Laura admitted that even if she and Cecilia were able to catch up to her while she was escaping during the IS Academy's anniversary, they would still lose.

In Volume 8, Tabane Shinonono said she would make an exclusive new IS for Madoka and asked for Madoka's preference: Long distanced, Close distanced, Special armed, Armor focused, Or mobility focused. In Looking For Memories Madoka is shown with her new IS, the Black Knight. It's shown to be very powerful and highly advanced.

Trivia

 * She appears on the cover of volume 10.
 * Madoka's name in kanji means "circle", also Madoka's name were based on PMM Main character, Madoka Kaname. This makes her the only one of her siblings whose name isn't a number or season in kanji.
 * When she is about to finish off Cecilia Alcott in the Cannonball Fast, Madoka says "...You're already dead." This quote is commonly attributed to Kenshiro of the Hokuto no Ken series.
 * Her nickname, "M", can refer to the word murder. Also commonly refers to a Masochist in Japanese Pop Culture, so it is, most likely, simply her initial.
 * It unknown if Madoka new IS is a 4th generation. It could be due to the fact that it was Tabane Shinononowho built it (Tabane being the only person who can build the 4th generation IS), also because of how powerful it was shown to be when Madoka was fighting many other IS pilots.
 * She was based on Homura Akemi.
 * Some say because of her similarity to Chifuyu, she might be a clone used as a supersoldier due to Chifuyu's incredible IS piloting skills. But this is questionable because Tabane Shinonono knows her.

 * Madoka is a girl, Ichika a boy.
 * Madoka is a loner, Ichika a people person.
 * Madoka dresses in black, Ichika dresses in white.
