Gitai Saimin

Meet Murakoshi Shinta, a seemingly ordinary student grappling with the wild delusions that haunt his imagination. Life had been nothing more than a monotonous routine until an extraterrestrial parasite took up residence on his most intimate part - his penis. This peculiar predicament has rendered him confined to his environment, fearful of exposing his groin in public. Yet, the tentacled alien possesses the uncanny ability to manipulate human minds, assuring Murakoshi that he remains unnoticed amidst the blissful ignorance of those around him.
