In 'Hell-O, Whose These?', players step into the shoes of an unapologetically sarcastic librarian in a library that exists between dimensions. While trying to catalogue the chaos of lost and forgotten books containing the souls of their previous owners, the librarian accidentally opens a portal to Hell. Patrons of the library transform into a bizarre blend of literary characters and demonic entities, each with their own eccentricities and lore. Players must navigate humorous dialogues, ridiculous quests, and absurd scenarios to return the wayward souls to their books—all while maintaining sanity as papers and spells fly around and chaos reigns. Along the way, players will unearth the library’s dark secret and face off against the begrudgingly charming demon librarian who holds the keys to both the library and Hell itself.
