After Nemesis was defeated by the King of Deviluke, Rito thought his life might settle back to normal. Or at least his version of normal, full of alien mad scientists trying to conscript him into a harem! But there's a flaw in his logic: he absorbed Nemesis into himself to save her, remember? And now, as she begins to recover, she's enjoying taking control of his body at very inopportune times...

A TROUBLESOME STOWAWAY After Nemesis was defeated by the King of Deviluke, Rito thought his life might settle back to normal. Or at least his version of normal, full of alien mad scientists trying to conscript him into a harem! But there’s a flaw in his logic: he absorbed Nemesis into himself to save her, remember? And now, as she begins to recover, she’s enjoying taking control of his body at very inopportune times...

Life isn't easy when you're a high school student who is kinda-sorta engaged to the princess of the entire galaxy. All Rito really wants is a simple life with Haruna, his one true crush, but the universe has other ideas. Jealous alien suitors keep on trying to ruin Rito's life-- and the worst cosmic enemy he's encountered yet is about to make her appearance!

'" The summertime hijinks continue with a trip to the beach! Rito gets an eyeful of Lala and Haruna in their swimsuits and the boys try to sneak into the girls'' rooms. Meanwhile, Lala''s enthusiastic feelings for Rito brew a storm of uncertainty in his heart. "'

'" Rito and friends face off against the wrath of a killer body-snatching sword from outer space--and that''s actually the easy part of his day! The really tricky part is a little more amorous. Rito''s been close to all kinds of gorgeous girls, and Momo''s even pushed him to start inducting them into his own personal harem, but there''s one thing he''s never done with any of them: kiss! Now that Lala''s heard about how common kissing is on Earth, is it time for Rito''s relationships to go to the next level? "'

'" Rito knows Momo as an alien princess with a dangerously dirty mind--but to her classmates, she''s the very picture of innocent beauty. The sudden appearance of her very own fan club on campus takes the idolization to a whole new level, as a coterie of awestruck boys seeks to protect their beloved Momo...from Rito himself! "'

'" Haruna has always been a breed apart from the other girls around Rito: demure, mild-mannered, and traditional. She''s even accepted that her friend Lala is in love with Rito. But a strange beverage from outer space is about to wipe away all her inhibitions. When Haruna has nothing to hold her back, will she finally confess her love to Rito? And will she want him all to herself--or become the newest supporter of the outrageous Harem Plan?! "'
