The plot of Saya no Uta is about a young guy named Fuminori. Like all people, he led a normal life, until in an instant his whole world is destroyed when he and his parents get into a terrible car accident.

As a result of a brain injury, the guy developed an inexplicable distortion in the perception of the world around him: the usual reality turned into a pitch hell. Absolutely everything around him is perceived as terrible piles of rotting meat, and his loving friends and other normal people seem like nightmarish, disgusting monsters. Everything that was dear in this life has become alien ... the world around has become an unbearable place. Fuminori tries to move on, shutting himself off from the world and doing his best to hide his disease from others, but this heavy burden gradually destroys his soul. While contemplating suicide in the hospital, he suddenly meets a beautiful girl named Saya who is looking for her father. For some strange reason, Saya doesn't see Fuminori as a monster, and they very quickly enter into a close relationship that will change their lives in the most incredible way...
