Homura Akemi

Homura Akemi (曉美 ほむら Akemi Homura) is one of the main characters in the Puella Magi Madoka Magica series.

Personality
Since her arrival at Mitakihara Middle School, she is immediately depicted as being very intelligent, athletic, distant, and cold. It is revealed in episode four that she is only like this because she has seen so much suffering during her tenure as a magical girl. Because of this, she does not want Madoka Kaname to become a magical girl and tries to do anything in order to stop her from making a wish with Kyubey, going as far as to attempt to injure and even kill the cat-like creature. Despite her cold attitude towards others, she still very much cares for Madoka as it is her sole objective to protect her due to the countless amount of blood, sweat, and tears she has shed over her jumps in time.

In the original timeline where her journey began, however, Homura is portrayed as meek, shy, timid, and is known around the school for her lack of confidence. She was also known for her physical incapability of performing in P.E. class; she would get dizzy upon doing even the simplest of warm-up exercises. This had the unfortunate result of her being a target of bullying, as heard on Drama CD 1. Overwhelmed by her perceived uselessness, she begins questioning her existence and until she begins her fated friendship with Madoka, her feelings do not change. Madoka, alongside Mami Tomoe, shows her the ropes and dangers of becoming a magical girl and notes that Madoka's own attitude became much healthier with every witch battle. In an ironic twist, in the anime timeline, we see how frail and meek Madoka is, compared to the current Homura whose personality had performed a complete 180-degree turn due to her experiences in multiple timelines.

Despite being regarded as emotionless by Sayaka Miki, Homura is far from it. Although she does not easily show signs of remorse, sadness, or pity, it is only because she had grown used to the suffering around her. Homura herself has stated that she always feels badly with each life she's unable to save or alter, but nevertheless, it does not slow her down from staying true to her main objective in saving Madoka Kaname.
