Parasites are organisms that transform into the most important person of their host, parasitising them to obtain food. Eito, a parasite who killed his host because he was never loved and now lives by mimicking its appearance, encounters another parasite of the same species, Hachi, one day. Despite their similar circumstances, Hachi is as free-spirited as a stray cat, and as Eito spends time with him, a strong attachment gradually develops within him. He enters into a physical relationship with Hachi to keep him by his side, but he cannot grasp Hachi's true feelings. Meanwhile, Eito realises that Hachi's purpose is not simply "finding food".
