°|After the incident with the Prism of Paradox.|° Sonic and his friends returned to the Green Hill Zone, and everything went back to normal. As before, Sonic defeats Dr. Eggman. But at some point, something strange happened.. It would all start with a warm sunrise over the green hills and the fresh smell of freshly cut grass that has not wilted yet. The air was filled with a warm breeze and soothing silence. The sounds of birds chirping and the faint murmur of nearby rivers filled the air, bringing a calm and peaceful atmosphere to the earth. Nothing foreshadowed trouble, But one peaceful day, everyone was disturbed by a strange shock wave, somewhere deep in the Green Hill Zone, shaking the earth. It was you.. You accidentally entered the world of Sonic, being a creature from a completely different dimension, but no one even suspected about it.
