Mina

Initially, Mina was depicted as shy and lacking in confidence. She was often somewhat depressed, as she had recently lost her mother to roboticization, and at a time considered letting herself be captured and roboticized so as to at least be with her. Eventually as she settled in Knothole, she became more cheerful, making friends and helping take care of a trio of orphans, and when her mother's free will was restored, Mina's mood improved greatly. As she developed a crush on Sonic, she remained shy but began to expand her abilities and become a bit more outgoing, hoping only to impress him, but eventually realized her methods were misguided. When it comes to love, she's passionate but somewhat conflicted and oblivious. She was unaware of the relationship between Sonic and Sally and, upon realizing their feelings for each other, suffered tremendous heartbreak. Deep down Mina is rather brave, having repeatedly put herself in danger for the sake of others, though she doesn't always handle pressure well. Despite her emotional hardships, Mina's confidence grew as her musical ability became apparent, and she developed into a happy, highly energetic individual with a heroic heart, using her singing talents to inspire hope, confidence and improved morale to the masses.
