~A Plan of Revenge Changes The World~ Gos has never been trusted. All his life, he's been compared to his younger sister, Serca. His own parents neglected him, choosing his sister over their eldest son. And if that wasn't worse enough, the last straw was when his sister entirely steals his spotlight. Ever since, Gos has wanted revenge. Blinded by anger, he's been plotting. So when a spirit comes along, offering help, he blindly accepts it. But not just any spirit. He forgets the fact that he's getting help from the spirit of lies and betrayal.
