Birthday: July 30 The protagonist, a transfer student who has not been able to make friends in his first month at St, Chronica's. Of all of the members of the club, he is the most gentle, balanced and socially competent in personality; but his unusual hair color, inherited from his late English mother, leads classmates to assume he is a violent and abusive delinquent and spread defamatory rumors about him. Because of his long experience of antagonism, Kodaka has become accustomed to fighting and can defend himself quite well. His father is working in the United States, and so he takes care of his younger sister alone at home, which has also made him a good cook. His childhood was characterized by frequent movement, and as a result he has few memories related to home life and close friendships; however, though he does not realize it at first, he and Yozora were childhood friends before his family moved. In volume 7 of the novel, it was revealed that Kodaka and Sena are fiancés betrothed by their father's which Sena fully accepts. In the end of volume 7, it is shown that Kodaka has been aware of the feelings of those around him for a very long time but plays ignorant because he fears losing the feeling of friendship that he wanted for such a long time. In volume 8, Kodaka asks Rika to be his friend. This is the first time Kodaka has made a true friend in a decade since Yozora. In volume 9 he declares to Sena that he loves her but abruptly states that he can't go out with her. Kodaka also made it further to the point of intending of doing sexual acts with Sena such as fondling and playing with her breasts, much to Sena's molestation, but Kodaka still infers that he can't go out with Sena in the hopes of protecting the Neighbor's Club's existence. After constantly trying to persuade Sena by kneeling and begging to her, Sena reluctantly accepts out of her love for Kodaka. Kodaka then thanks Sena for her understanding as he claims to himself that his first battle as a useless protagonist ended with a spectacular victory.
Birthday: July 26 Blood Type: A 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."
