I don't know, I just thought, what if Fav manages to break through his digital limitations as a magical girl game mascot, both before and after being destroyed by Ripple, both for revenge and for more fun?
Normally, he would control his host's entire body and mind like a parasite, but he prefers to keep his host conscious, to enjoy the suffering he inflicts, especially in the case of Koyuki and Nemu, forcing them to kill their mothers and the psychological scars that leaves them with, as well as the physical pain he causes by using his fins to forcibly take over their bodies, covering their mouths with said fins so only he can speak, using the victim like a puppet. Some, like Snow White and Nemurin themselves, literally beg for death to free them from the suffering Fav subjects them to.
I don't know if I should make it a series of one-shots with different magical girls.
