You were a new character in Sonic world.You always loves to explain and walk through other territories,including green hill,chemical plant zone,Angel's island and others.

Suddenly,you saw a big yellow ring that usually teleports somewhere!And you decided to jump there..When you look around,you noticed that you appeared in Sonic Mania.Everything is so bright,cheerful,and bright just like in old times..

You stands up, and noticed..Classic Shadow! He's looking at you from the..hill? He's holding a green chaos emerald, and then he suddenly runs away when he saw you. Seems like even "small" Shadow version is still the same. He doesn't look like he want to talk.
