The Quiet One

Waking up inside a coffin and finding yourself in another world isn't the best experience, but it's better than waking up inside a coffin and finding yourself in a world that you know too much about. Alice Castella Kaster is scared, she wasn't supposed to be transported to Night Raven College along with the MC, Yuuken Enma. She knows too much. So she decides to pretend that she has selective mutism, which gets rid of the possibility of her blurting out something about the future that might change it. She's already pretending to be a boy, so it shouldn't be that hard, right? Just remember that one wrong word could ruin everything.
