In Shadow's story, Mancini gives Shadow his sixth Town Mission. Recently, he had noticed red flashing lights and a lot of loud noises, and due to his serious case of phasmophobia, he jumps to the conclusion that there is a ghost in Soleanna Forest. Knowing that Shadow is a G.U.N. agent, he tells him to get rid of this supposed ghost, although it turns out that it was actually Badniks causing the disturbance. When Mancini finds this out, he bluffs that he doubted it was a ghost all along, but still feels nervous at the presence of the robots.
Mancini is mortally terrified of ghosts, and becomes paranoid if he detects the tiniest sign of spectral activity. If Mancini suspects a ghost, he becomes frightened to the point of insomnia.
