The Homunculus is a large, white monster; a mutation of Two's orphaned children as a result of the Intoner's song.
Cent used Two's song in an attempt to heal the children's wounds and illnesses. However they became cursed, and formed into the Homunculus. The voices of the children emitting from the creature still call out to Two, which, combined with her guilt of killing people infected by the curse, reduced her to her fragile state. She and Cent were forced to kill the monster to put the children out of their misery.
- The tip of the Homunculus' tail consists of a human torso.
- There have been many appearances of the Homunculus being in science, fiction, and music.
