Keima Katsuragi, known as the "God of Conquest," continues his mission to banish wayward spirits that have seized the hearts of women. Despite being bound by a contract with the demon Elsie, he must rely on his expertise in dating simulators to capture the elusive phantoms lingering within the souls of actual, three-dimensional girls. However, Keima's task is far from easy. He must face a diverse array of opponents, from exorcising martial arts practitioners and student teachers to confronting Elsie's friend from the underworld. These challenges test his intelligence and could even catch him off guard. Although Keima prefers the 2D realm, he is trapped in the unremarkable world of reality, and thus must persevere in his pursuit of affection.
