Hobby: Reading/Bulling Sena
A cruel and selfish black-haired girl who says she understands and respects bullying but resents being called a bully herself, Yozora's difficult personality drives away anyone who might wish to make friends with her before she meets Kodaka. She is physically abusive towards, and often argues with, Sena and manipulative towards Maria, who she cons into giving up an empty room for the use of the Neighbor's Club, and Yukimura, who she fools into working for the club as a crossdressing cosplay maid. The only person she can't insult is Rika, as Rika takes whatever insult she gives her and deflects it back with a dirty joke that leaves her tired - to the point where she just does what Rika says (like crossdress for example) rather than argue.
She is Kodaka's childhood friend, though at the time, he believed that she was a boy, calling her "Sora"; her nickname for him was "Taka." On the pre-arranged day before Kodaka moved, she intended to wear a skirt and reveal her gender to him but was too embarrassed to do so. Kodaka eventually recognised her after she had to cut her hair short due to it catching on fire. She seems to have feelings for Kodaka.
