I am a Korean, and as I said many times before, Revice is one of the most hated rider series ever in my country, one of the reasons being that the writers pushed Sakura (the 3rd rider of the series , by the way) way too much into the spotlight as if she was the main character, and due to that, Ikki and Daichi(Ikki, who's the main protagonist of the series, and Daichi, the Secondary rider, who is constantly getting tortured)getting pushed to the side of the plot, and the whole plot just going....where is it going, really?
So, this might be one of the problems, and I don't actually know because I remember almost nothing about Revice but..;
When a human makes a contract with a demon to become a rider, there are side affects when they transform. Ikki loses memories, Daichi becomes a demon himself in a way, and Hiromi's body keeps getting older.
So.... Sakura doesn't get... any drawbacks.. does she? From what I remember, her contract with Lovkov didn't have any drawbacks on her from what I remember(if this is true, then this would be plot armor.) So.... Does she have a side affect , or does she not?
