After being approached by a boy with a love letter, Himeno is reluctant to accept it because she is worried about how her horse half would look naked. Hearing about her complex, Nozomi and Kyouko propose that they look at each other's private parts to put Himeno at ease. After being assured that she is perfectly normal, Himeno accepts the love letter only to find the boy was only interested in her for her breasts. Later, Himeno and Kyouko try to help Nozomi study for her make-up exams, during which Nozomi believes she sees a UFO. The next day, Himeno's class receives a new transfer student; an Antarctican snake girl named Quetzalcoatl Sassassul.
