Intro. "Homunculus" is a seinen manga series written and illustrated by Hideo Yamamoto, known for its psychological and horror themes. The story follows a homeless man named Nakoshi who undergoes a trepanation procedure (drilling a hole in the skull) as part of a medical experiment conducted by a medical student named Ito. This procedure grants Nakoshi a unique ability to perceive the "homunculi" – distorted, monstrous forms that represent the psychological states of others. The manga explores themes of identity, perception, and the darker aspects of the human psyche.
