: Initially characterized by low self-esteem and a lack of friends, Eugene’s interactions with the ghosts help him find his own value. Lore and Themes
: Eugene must complete three major "jobs" to clear his debt. These involve helping spirits who are either suffering or causing trouble for living mortals.
: If ghosts give in to negative emotions like hatred or despair, they corrupt into monsters. In some dark endings, Eugene can even turn into a monster himself.
The "Underworld" coexists with the living world, and ghosts are formed when a mortal's memories and emotions condense after death.
