Keima is back, and together with Elsie the hunt for loose souls continues on. This time however, they are joined by Elsie's friend and fellow Demon, Haqua.

To counter this threat, Keima Katsuragi is conscripted into unsealing the five Jupiter sisters - the Goddesses who sacrificed themselves in order to seal Weiss.
