Hearing about Risa and Mio talk about a perfect body, Haruna thinks about her bust in relation to Lala and how she's failed to enlarge them, though she is happy when Rito says he values personality more than he does breast size. She and Oshizu find Nana angry about Momo teasing her for having a flat chest. Nana works together with Haruna and Oshizu to enlarge their breasts. After many attempts, Haruna tells Nana to stop and quotes Rito that personality matters more.
Haruna finds a helpless stray dog with Maron and takes him in for care. Maron asks the dog about his origin, who turns out to be Rito stuck inside a dog's body thanks to another Lala invention. Haruna takes Rito into the shower with her to clean him up. Maron tries to teach Rito how to act like a dog and has him lick Haruna as a way of showing affection. However, Rito becomes overwhelmed and flees. Lala finds Rito and puts him back in his own body, offering to turn him into a cat next time.
Mikan wishes to change bodies with Yami to experience her abilities. Yami agrees and Lala performs the change. With switched bodies, Mikan struggles to control Yami's abilities and has to escape the principal. Yami, on the other hand, easily beats up the principal without her abilities and learns about siblings and caring from Rito, who does not know about the body swap and thinks Mikan is sick or depressed. Afterwards Yami admits she has learned new things about Rito and is slightly envious Mikan has him as her brother.
