Kami nomi zo Shiru Sekai - All Seasons

Keima Katsuragi, the "God of Conquest," returns to his quest of expelling runaway spirits that have possessed the hearts of women. Still stuck in his contract with the demon Elsie, he must continue to utilize the knowledge he has gained from mastering multitudes of dating simulators and chase out the phantoms that reside within by capturing the hearts of that which he hates most: three-dimensional girls. However, the God of Conquest has his work cut out for him. From exorcising karate practitioners and student teachers to the arrival of Elsie's best friend from Hell, he is up against a wide array of girls that will test his wit and may even take him by surprise. Though he would much rather stick to the world of 2D, he is trapped in lousy reality, and so Keima must trudge forward in his conquest of love.

Having freed a myriad of women from the runaway spirits possessing their hearts, the "God of Conquest" Keima Katsuragi is confronted with a new task: find the Jupiter Sisters, the goddesses that sealed Old Hell in the past. Diana, the goddess that resides inside his childhood friend Tenri Ayukawa, explains that they have taken shelter in the hearts of the girls he had assisted previously. Moreover, once Diana and her sisters are reunited, their power can seal the runaway spirits away for good and relieve Keima of his exorcising duties. Though he is initially reluctant to get involved in yet another chore, everything changes when tragedy befalls one of the hosts. Discovering that the goddesses are being targeted by a mysterious organization known as Vintage, Keima is caught in a race against time to reunite the sisters and rescue the girl who has already fallen prey. With deeper resolve than ever before, Keima works together with demons Elsie and Haqua to recapture the hearts of the girls he had charmed in the past. However, the road ahead is a difficult one, as he is soon met with the consequences of his previous conquests.
