Saya no Uta (沙耶の唄, Saya no Uta? lit. Saya's Song) is a visual novel by Nitroplus with horror elements.
Some fans consider the plot to be Lovecraftian. Although direct references to the Cthulhu mythos are minimal, the dark, eerie atmosphere is reminiscent of his works. Nitroplus is also known for the production of the heavily Mythos-inspired Demonbane series.
Many plotlines of Saya no Uta are similar to the manga Phoenix - Resurrection, specifically the life of Robita. At one point of the dialog, the main character explicitly references these similarities.
