Saya No Uta - Plotline - Endings

Endings

There are three endings to the visual novel, depending on the choices that the player makes during the course of the game:

• Ending 1

Saya helps Fuminori return to normal, but suddenly leaves because she does not want to reveal her true form to Fuminori. Fuminori contacts the police, is charged with murder, and becomes confined in a psychiatric hospital for the rest of his life. Saya visits Fuminori once and, refusing to let Fuminori see her and hear her real voice, communicates using text messages in a cell phone passed through an opening in the door. Fuminori confesses his love and promises to comfort her at any time. Saya leaves to search for her father, whom she believes could help her "go back to where she came" (possibly alluding to the other dimension from which Saya came), and Fuminori continues to wait for her eventual return in his cell. It is implied that the two never meet each other again. In this ending Yoh is not mutated nor is she killed.

• Ending 2

Fuminori accepts what has happened to him and decides to remain the way he is to stay with Saya. To keep what has happened a secret, Fuminori decides to kill Kōji by pushing him into a dried up well at Masahiko Ōgai's abandoned house in the mountains. However, Kōji is saved by Dr. Ryōko Tanbo, and they discover Ōgai's log with information of Saya. Kōji returns with plans to kill Fuminori in vengeance, and Ryōko offers to help him. After getting Fuminori's location by blackmailing him with information of Saya, the duo enter to kill Fuminori, and in the ensuing struggle Kōji kills a hideously mutated Yoh while Fuminori mortally wounds Ryōko. Before dying, Ryōko, using liquid nitrogen, inflicts a fatal wound to Saya. Realizing he is going to lose Saya, Fuminori loses all will to live and commits suicide. Saya uses her last strength in order to crawl to Fuminori's body while being repeatedly hit with an iron pipe by Kōji. She dies soon after reaching with him. After everything he went through, Kōji's mind shatters: he is left with delusions and paranoia, constantly plagued by nightmares of his deceased friends and vivid hallucinations of Ryōko. He purchases a single bullet for his revolver, implying that if his nightmares become unbearable he will commit suicide.

• Ending 3

The events in this ending are similar to the previous one, except Kōji does not receive help from Ryōko and attempts to kill Fuminori by himself. Without Ryōko's interference, Saya and Fuminori kill Kōji together. Afterwards, it turns out that Saya has reached the last stage and ultimate goal of her life: reproduction. Saya releases a spore-like matter into the atmosphere—a mutating agent aimed at humans, created by researching the human genome obtained during sex with Fuminori. The agent is spread across the globe by updrafts, slowly turns the entire human population into members of Saya's species. The end of the story is seen from Ryōko's perspective, and it is implied that Fuminori will see beauty in the world once again since it will be filled with her kind. Fuminori and Saya are said to live happily ever after, at the expense of everyone else in the world.
