Rito versucht Celine eine außerirdische Erfindung wegzunehmen, die noch nicht ganz ausgereift ist. Als diese durch ein Versehen aktiviert wird, ist die Aufregung groß: Die splitternackte Yui fällt wie durch Zauberhand direkt in Ritos Arme.
Rito tries to take one of Lala's inventions from Celine but Celine activates it and summons a naked Yui for Rito. The next day, Rito catches a train and finds Yui inside with an angry glare. She pulls Rito to a side protecting him from other women. Rito tries to talk to Yui by asking why she is here. Yui was delivering papers while Rito was shopping for novelty items. The train then becomes more crowded, squeezing Rito and Yui together and forcing Rito to grab Yui in weird places. One of Rito's items also molests Yui. At arrival, Rito finds one of his items running, angering Yui. Meanwhile, Mea asks Nemesis for feedback about her experience on Earth. Nemesis finds it too peaceful and is waiting for the Darkness form to activate. Mea then questions Nemesis about the Darkness form inside Yami but Nemesis declines to explain and assures Mea that time will come, making Mea upset. As for Yami, Mikan tells Yami not to be swayed by Nemesis. She also requests Yami to always seek her for help. On the way home, Mikan spots Mea while grocery shopping and finds her basket filled with sweets. She advises Mea to have a better diet and invites Mea for dinner. Mikan also hopes to learn more about Mea given that she is Yami's sister. At home, while Lala washes up Celine and gets her breasts sucked on, Mea requests to watch Mikan cook. Mea takes interest in cutting vegetables and volunteers. Mikan teaches Mea and remembers the same experience Yami had. When it's Mea's turn to cut, she feels a cutting sensation and cuts the vegetables wildly with her abilities, ripping everyone's clothes in the process. She stops just when Lala arrives. After Mea leaves, Mikan is skeptical whether she can befriend Mea like Yami.

Rito intenta quitarle uno de los inventos de Lala a Celine, pero Celine lo activa y convoca a Yui desnuda para Rito. Al día siguiente, Rito toma un tren y encuentra a Yui adentro con una mirada enojada. Ella lleva a Rito a un lado para protegerlo de otras mujeres. Rito intenta hablar con Yui preguntándole por qué está aquí. Yui estaba entregando papeles mientras Rito compraba artículos novedosos. El tren se vuelve más concurrido, apretando a Rito y Yui juntos y obligando a Rito a agarrar a Yui en lugares extraños. Uno de los artículos de Rito también molesta a Yui. Al llegar, Rito encuentra uno de sus artículos corriendo, enojando a Yui. Mientras tanto, Mea le pide a Nemesis comentarios sobre su experiencia en la Tierra. Némesis lo encuentra demasiado pacífico y está esperando que se active la forma Oscuridad.
