Мікі Саяка

In order to cure Kyosuke's hand, which was damaged in an accident which robbed him of his ability to play the violin, she becomes a Puella Magi. Sayaka's weapon of choice is a sword. She also has regenerative powers stronger than anyone else due to the nature of her wish. Sayaka hates people who think only of themselves whilst hurting others and is easily provoked into a fight. After learning how Puella Magi are created, Sayaka starts to descend into despair, as she believes she's now no better than a zombie and thus cannot openly admit her love for Kyousuke. Her state of mind only worsens as one of her two best friends, Hitomi, confesses that she has feelings for Kyousuke too and makes advances on him.

At the same time, she also refuses to purify her Soul Gem with Grief Seeds and neglects it to become tainted. At the end of episode 8, her Soul Gem was finally exhausted, and Sayaka turns into the witch Oktavia von Seckendorff. She dies in a battle with Sakura Kyouko, who sacrifices herself in order to not let Sayaka die alone. In episode 10, it's revealed that during Akemi Homura's third time loop, Sayaka also suffered the same fate of turning into a witch, and was killed by Homura with an explosive.

Sayaka's design is prominently blue, which makes her appear heroic and 'just', further reinforced by her wearing a white cape, symbolic for goodness and purity. Aside from her color scheme conveying her being a hero who fights for justice, it also foreshadows her eventual melancholic downfall. Sayaka also noticeably differs from the rest of the cast with her short hair. Again amplified with traditionally male aspects of her design, Sayaka is a tomboy. She would, for instance, bring a baseball bat on the girls' first hunt, whereas the traditionally feminine Madoka brought a notebook.

Sayaka has tareme eyes, symbolizing fragility and sadness. Although this might look like it contradicts Sayaka's personality, it foreshadows her losing her belief of fighting selflessly in the name of justice and starts falling into despair.
