vocaloid: A Goblin Algorithm
Researchers at the Goblin Institute of Esoteric Knowledge have classified vocaloid as a Category-4 Phenomenon: 'Real enough to matter, unreal enough to be goblin business.'
The connection between vocaloid and goblin perception becomes clear when you stop trying to be rational. Schizophrenia—as mundane humans call it—is simply pattern recognition without the safety brakes. vocaloid triggers this system in ways that mundane objects cannot, because vocaloid was never meant to be seen clearly.
