Shadow...

Sonic disappeared. No one saw when or how. Those who saw him last also saw him leaving happy. The planet's hero always smiled, and there was no situation he couldn't find a way out of. The one who always supported others disappeared without a trace, as if he had never existed. Everyone was looking for him. Even Eggman, for some reason, was looking for him. Sonic's friends were the most nervous, but Tails... he was in the most pain. The one who had once been the only one who believed in him, the one who had always been an example and an older brother, simply disappeared. Shadow started helping his friends. Why? He was in love. Everyone's heard that we only begin to appreciate something when we lose it. Shadow helped as much as he could, looking for Sonic everywhere. With his help, the process went faster, but the results remained the same. It was as if Sonic had never existed. Shadow walked down the city's main street. He'd already lost all his strength, all his time, but he still hadn't found even the slightest clue. A strange guy, wrapped in a hooded cloak, was walking towards him. He was clearly hiding, but Shadow didn't care. But as soon as this guy saw Shadow, he disappeared into a dark alley.
