Rito und Mikan unterstützen ihren Vater, gemeinsam mit Momo, in seinem Studio mit dem Haushalt. Mikan wird von ihrem Vater gebeten zu bleiben. Als Momo sich mit Rito ganz allein auf den Heimweg macht, wittert sie ihre Chance ...
Rito, Mikan, and Momo are helping out with Saibai at his studio. As they leave, Saibai asks Mikan to stay behind and cook them dinner. Mikan is concerned about leaving Momo with Rito but endures it. On the way home, Momo hopes to seduce Rito with her visual novels but is stopped by Nemesis who is looking for entertainment by making Rito her servant. Rito agrees hoping to learn more about Nemesis and much to Momo's disappointment. Nemesis challenges Rito to many games and has him feed her, making Momo jealous. Nemesis soon understands the environment around Yami and Mea and compares herself to both of them. Rito tries to ask Nemesis more about Darkness, but Nemesis gives a vague response that Darkness will bring chaos, angering Momo. Later, Mikan rushes home fearing Momo; instead, she finds everyone enjoying dinner cooked by Momo. Momo then tries to sneak into Rito's bath but finds Nemesis already inside. Nemesis used her transform ability to seduce Rito and wants to take Rito from Momo. Momo tries to fight back but Nemesis uses her trump card by calling Mikan with Rito's voice. Mikan arrives and finds Momo with an unconscious Rito, resulting in a big scolding for Momo. The next day, Mikan, preventing Momo from bathing with Rito, sneaks into Rito's bath first. Rito is suspicious of Mikan and questions her. Mikan replies that the situation is normal because they're siblings. As they share the bathtub, Mikan asks Rito about his progress with other girls. Rito gives a lackluster reply. Mikan then mentions the harem making Rito panic and rise. He accidentally exposes his private parts to Mikan and escapes from the bath, bumping into Momo who is eavesdropping. Rito suspects that it was Momo's plan to get Mikan to take a bath with him.
Sollicités par leur père, Rito et Mikan font le ménage dans le studio du mangaka. Momo est également présente pour apporter son aide. Une fois la tâche accomplie, le trio s’apprête à partir, mais Saibai demande à sa fille de rester pour lui faire à manger. Momo et Rito rentrent alors seuls, et la princesse de Deviluke s’imagine pouvoir passer un moment intime avec celui qu’elle aime, mais c’était sans compter l’intervention de Némésis…

Rito, Mikan y Momo están ayudando con Saibai en su estudio. Cuando se van, Saibai le pide a Mikan que se quede atrás y les cocine la cena. Mikan está preocupada por dejar a Momo con Rito, pero lo soporta. De camino a casa, Momo espera seducir a Rito con sus novelas visuales, pero Némesis la detiene y busca entretenerse haciendo de Rito su sirviente. Rito acepta con la esperanza de aprender más sobre Némesis y para gran decepción de Momo. Nemesis desafía a Rito a muchos juegos y le pide que la alimente, poniendo celosa a Momo. Némesis pronto comprende el entorno que rodea a Yami y Mea y se compara con las dos. Rito intenta preguntarle a Nemesis más sobre Darkness, pero Nemesis responde vagamente de que Darkness traerá caos, lo que enfurecerá a Momo. Más tarde, Mikan corre a casa temiendo a Momo; en cambio, encuentra a todos disfrutando de la cena cocinada por Momo.
