Rito Yuki continues to be caught in over-the-top perverted scenarios, now uncensored. The alien Deviluke sisters - Lala, Momo, and Nana - still use their unique abilities in an attempt to grab Rito's love confession. Momo, in particular, has a vision: a harem of women all in love with Rito, with Momo herself in the center. After all, if everyone has an equal share of Rito, everyone wins - at least, she thinks. As she enacts this plan, the former alien mercenary Yami, aka Golden Darkness, struggles between her former life as a killer and her current life on Earth. Things get complicated when Mea, a girl with powers similar to Yami's, becomes interested in Rito. Just who is this new enemy?
