Saya no Uta

A horror visual novel about Fuminori Sakisaka, a medicine student who suffers an accident that leaves his perception of the world distorted: everything and everyone is perceived as a twisted mass of intestines, flesh and blood. Everything, except Saya.

Rot. Decay. A wasteland of twisted, pulsing flesh. Sakisaka Fuminori survives a terrible accident only to find himself trapped in a nightmare with no escape. His friends offer him comfort and support, but their warmth cannot reach his frozen soul. Then he meets a mysterious girl named Saya, and little by little, his madness begins to infect the world.
