Emiri Uchi 内笑美莉
Emiri Uchi, better known in the English translation by her nickname "Ucchi," is Tomoko's second then third-year classmate. Because she could not form a group of five with her friends for the school trip to Kyōto, she along with Yoshida and Yuri are put in Tomoko's group. Since that time and despite her initial dislike of Tomoko, she has become progressively interested in to obsessed with Tomoko to the point of developing a crush while still declaring that she finds her behavior "disgusting".
Aside from a possible view of her from behind on the cover page of Chapter 20, Uchi first appears in Chapter 59 during Tomoko's second year of high school when she and Tomoko sit next to one another on the bus to a baseball game.
