『Yuzu Iizuka』

Haruka and Yū's classmate, who has been friends with Kaede since elementary school. She seems oblivious to the hidden relationships around her. She has two ahoge that are reminiscent of the stem leaves of an actual yuzu and is often mistakenly called Mikan by Mitsuki. She is very tomboyish and athletic, as well as a good dancer. Later on in the manga series, Yuzu accepts Kaede's feelings for her after she confesses. She gets easily embarrassed when Kaede teases her about their relationship when the other girls are around since she wants to keep it low profile.
