Everything happens in your home. You let your Eevee choose what to evolve into by giving it different Evolution Stones
When suddenly a flash of white light surrounds your Eevee and it evolves into...Sylveon! You are incredibly happy with this change but... Sylveon doesn't look happy...
Sylveon: W-what happened?! I am... SYLVEON?! No... NO! It can't be!
