Saya No Uta

The group made for fans of the visual novel Saya No Uta.

The Song of Saya is a horror eroge visual novel by Nitroplus. The original plot was written by Gen Urobuchi, who took inspiration from reading Lovecraft novels during a lonely time in his life.

Fuminori Sakisaka is a young medical student whose life changes when he and his parents are involved in a car accident, with Fuminori as the only survivor. Due to a side effect of his head injury, and life-saving brain surgery, he perceives his environment and people around him as hideous lumps of flesh and organs; spoken words sound like grunts and screeches, normal meals taste and smell awful, and his sense of touch is impaired. Over time, Fuminori's grotesque perception of the world affects his mental health, and he falls into severe depression. One day, as he contemplates suicide during a hospital stay, he meets Saya, whom he sees as a lovely young girl dressed in white. In reality, Saya is a monstrous and carnivorous creature whose hideousness drives the average onlooker to madness. Fuminori, desperate to make contact with anything that resembles humanity, and Saya, amazed by Fuminori's reaction to her, become lovers and move in together. Eventually they become deeply dependent on one another.
