Homunculus (en) follows Nakoshi, a homeless man living in his car, who agrees to let a medical student perform experimental trepanation—drilling a hole in his skull—in exchange for money. The procedure grants Nakoshi the ability to see people's true inner selves manifested as grotesque, surreal homunculi, revealing their deepest traumas, secrets, and repressed desires. As Nakoshi explores this dark psychic world, he confronts his own painful past and the distorted perceptions of those around him. Readers are drawn to its psychological depth, disturbing body horror, and profound exploration of identity, loneliness, and the human psyche, delivered through intense, unsettling imagery and a gripping narrative that challenges perception of reality.
