Keima Katsuragi, the dating-sim prodigy known online as the 'God of Conquest,' faces a new crisis when six ancient goddesses, the Jupiter Sisters, are found dormant inside girls he previously helped. Unlike his earlier conquests, these girls now remember him, and a rogue demon faction called Vintage is hunting the goddesses before Keima can reawaken them. This third season continues Keima and Elsie's story, jumping ahead in the manga timeline.
