Спустя год после прибытия на [[Землю]] Лала [Lala Satalin Deviluke] все еще полна решимости влюбить в себя Рито [Rito Yuuki], и прикладывает для этого все силы, хотя и знает, что тот продолжает питать огромную страсть к Харуне [Haruna Sairenji]. Бедному Рито еще только предстоит знакомство с младшими сестрами Лалы, Момо [Momo Belia Deviluke] и Наной [Nana Astar Deviluke], которые делят кров с его собственной сестрой, благоразумницей Микан [Mikan Yuuki], а также Селин [Celine].

Нас ждут веселье и неприятности, старые знакомые и новые лица, очередные изобретения Лалы (грозящие мировой катастрофой), заказ на Рито киллеру и куча нерешенных в первом сезоне вопросов.

Rito Yuuki never gets a break—he's always finding himself in lewd accidents with girls around him. Although his heart still yearns for Haruna, his childhood love, Rito can't help but question his feelings for Lala, the alien princess who appeared in front of him and declared she would marry him. But now, it's not just Lala he has to deal with: her younger twin sisters, Momo and Nana, have also traveled to Earth, wanting to meet their older sister's fiancé, and just as luck would have it, they end up staying at Rito's home.

Meanwhile, amidst the bustle of his new family members, Yami, the human weapon girl, begins her pursuit for Rito. It's not an easy life for Rito as he deals with uncertain love, punishment for being a pervert, and a girl dead set on murdering him.
