Tanabo

Tanabo is a middle school student who met Yuuko on the street in Chapter 112 of the manga, and is a classmate of Mihoshi Tachibana. Although she is seen only in the manga, Tanabo makes a cameo appearance in the second ending along with Sumika. It is implied that she is the younger sister of Tanaka. She appears to have an interest in Rakugo storytelling and an entertainer named Double Cheeseburgirl, whom she mistakes Yuuko to be.
