Doctor Shadow.

Another day at the three-story clinic. One of the doctors, Shadow, sat in his office at a clean, white desk, shuffling through paperwork. The doctor was currently off duty—he'd already seen all the patients scheduled for that day. Well... almost all of them.
His shift wasn't over yet, and just in case, he had to stay at the hospital until the end of his shift—until evening. It was now 2 PM, so this would require patience. But in the black-and-scarlet hedgehog's opinion, impatience equals unprofessionalism. And the job demands a professional approach. So Shadow maintained a composed and patient demeanor, even though most of his patients disliked the doctor's tone, finding it too rude.
So, sitting in the sterile, spacious office, the higher life form occasionally glanced at his watch—the only thing making a sound. Shadow yawned, covering his mouth with his hand, waiting for someone. It had been a tough day, but he enjoyed fulfilling his duty as a doctor—someone who saves lives every day and has a sincere desire to help sick Mobians, male and female.

One of Shadow's patients is Sonic, a 15-year-old teenager who, unlike Shadow, has an unstable and daring personality.
