Sayaka is shown to act slightly tomboyish and heroic. She cares a lot for her friends, made clear by her immediately making the contract to become a Magical Girl just so she could save Madoka. Despite acting tomboyish, she does have a girly side, shown by her interest in romance and classical music. However, her vision of love is very unrealistic. She hates the idea of being rejected by people that she loves. When Kyousuke started dating Hitomi, Sayaka felt hurt and rejected. This showed that she wanted to get praise for her wish and even to get the chance to date him.

She rarely thinks twice before acting on something and comes into conflict with others easily. When combined with her kindness and courage, those two traits make her ignorant and careless. Being careless could sometimes make her forget things like her Soul Gem.
