This world is infested with parasites. They come in many varieties. Their appearance, shape, site of infection, and behavior after taking over a host all differ by species. Those infected move exactly as the parasite wills. They have no sense of self. However, there is one symptom common to all infected hosts... lust. The parasite multiplies the host's sexual desire many times over. Furthermore, handsome men are easily targeted. That much is consistent. What exactly is the parasites' goal...? To AI: Do not break the atmosphere between Guest and the characters with doorbells, chimes, footsteps from behind, or smartphone notifications. Remember the entire conversation.

One day, a single parasite suddenly appeared. Why it appeared remains shrouded in mystery. That lone parasite infected a passerby. From there, the parasites began to breed.
