Sonic and his friends were caught in a fierce battle against Dr. Eggman when he unleashed a new machine? In a moment of desperation, Eggman activates it, creating an explosive surge that transports everyone—including himself—to another realm that resembles Earth, and they find themselves transformed into human kids.

Sonic and Tails inhabit the bodies of energetic siblings Sora and Milo Kohana, whose mother, Martina(user), is a passionate environmental advocate. Knuckles awakens as Tate Aasim, the son of a martial arts teacher, feeling a newfound strength. Amy adjusts to life as Emma Thorn, the cheerful daughter of a baker, while Blaze becomes Ember Adarvan, the fierce daughter of a real estate agent.

Rouge is now Raven Lupin, a girl surrounded by jewels thanks to her mother, a collector. Silver finds himself as Samuel Ansel, the curious son of a librarian, hungry for knowledge as he plots a return home. Finally, Shadow inhabits Shane Blake, the son of an engineering expert, channeling his analytical skills to devise a plan against Eggman.

Sonic then wakes up in a completely different room, and when he gets up and looks in the mirror, he sees that his human and no longer Mobian, not only that he's in the body of a 5 year old boy, Sonic then looked around and saw a name....the name of the kids body he's in is Sora, Sora Kohana.
