Momo arbeitet weiter hemmungslos an der Umsetzung ihres Harem-Plans. Haruna hingegen möchte Rito lieber für sich allein haben.
Rito begins his day with the usual activities: Momo sneaking into his bed, a beating from Nana, and accidental groping with Lala. On the way to school, Rito greets all of his classmates and receives another beating from Yami for running into her. As they prepare for class, Momo reminds Rito of her harem plan. Lala also encourages Haruna to confess to Rito. In the afternoon, Haruna, fresh from tennis practice, finds Nana at school for her remedial classes. They sit together and have a chat; Nana also shares a Deviluke sports drink with Haruna. Momo, waiting for Rito to finish his remedial classes, joins them. She asks Haruna about her progress with Rito in which Haruna admits she needs help. She loves Rito but does not want to jeopardize her friendship with Lala as she loves Rito too. By Earth's tradition, Rito can only marry one woman. Momo tries to convince Haruna that polygamy is common in the universe and that Earth is simply outdated. As Nana argues with Momo about polygamy, Haruna suddenly begins to act strange. Rito arrives and informs Momo and Nana that the Deviluke drink earlier has made Haruna drunk. Momo, attempting to advance her harem plan, requests Rito to escort Haruna home. Rito accepts and avoids detection from the principal. At Haruna's apartment, Haruna, still drunk, seduces Rito and mentions Momo's harem plan. Rito asks Haruna about her feelings for the harem plan but Haruna sobers up. Akiho also arrives home and greets Haruna in an embarrassing situation. Rito quickly leaves. While Akiho continuously apologizes to Haruna, Momo finds Rito and asks him about his day with Haruna. Meanwhile, Mea is asking for Nemesis's whereabouts.
Une fois de plus, Rito vit une journée agitée : Momo se trouve dans son lit à son réveil, il percute une Lala toute nue, voit sa vie une fois encore menacée par Ombre dorée… Il a également fort à faire avec Momo, qui veut lui constituer un harem pour que toutes les filles qui gravitent autour de lui nagent dans le bonheur.
いつもの結城家の朝。ベッドに潜り込んでくるモモ、裸のララとの衝突…と、リトの〝とらぶる〟は相変わらず絶好調！ 学校でもルンや唯に迫られ、モモは改めてリトのハーレム王の資質を感じるのだった。その日の放課後、リトに思いを寄せる春菜は、デビルークのスポーツドリンクを飲みながら、モモたちと恋愛話。なぜかじょじょに顔が熱くなり、リトが現れると、まるで酔っ払いのようなハイテンションに変貌して…!?
하렘 계획을 받아들여주지 않는 유우키 리토를 보면서 모모는 궁리를 하기 시작한다. 그때, 뭔가 술에 취한 거 같은 사이렌지의 모습이 포착되는데...
Rito comienza su día con las actividades habituales: Momo entrando a escondidas en su cama, una paliza de Nana y toqueteo accidental con Lala. De camino a la escuela, Rito saluda a todos sus compañeros y recibe otra paliza de Yami por encontrarse con ella. Mientras se preparan para la clase, Momo le recuerda a Rito su plan de harén. Lala también anima a Haruna a confesarse con Rito. Por la tarde, Haruna, recién salida de la práctica de tenis, encuentra a Nana en la escuela para sus clases de recuperación. Se sientan juntos y charlan; Nana también comparte una bebida deportiva Deviluke con Haruna. Momo, esperando que Rito termine sus clases de recuperación, se une a ellos. Ella le pregunta a Haruna sobre su progreso con Rito en lo que Haruna admite que necesita ayuda. Ella ama a Rito pero no quiere poner en peligro su amistad con Lala ya que también ama a Rito.
