Known as the 'God of Conquest,' Keima Katsuragi resumes his mission to drive away runaway spirits that have inhabited women's hearts. Bound by contract to the demon Elsie, Keima must apply his expertise in dating sim games to win over the spirits lurking within real girls, a task he finds distasteful. His challenges range from dispelling spirits from martial artists to student teachers, all while facing unexpected obstacles like Elsie's underworld companion. Despite his preference for the 2D world, Keima is compelled to navigate the complexities of real-life relationships and continue his pursuit of love.
