She, along with Le Fay Pendragon, later move into the Hyoudou Residence in Volume 14 as semi-permanent residents so that she could teach her sister on how to use her powers better while making a mess out of Issei's house (much to his dismay) with Le Fay apologizing for Kuroka's actions. After seeing Kuroka reading a book regarding Senjutsu to teach her sister, Issei asked if Kuroka wanted to reconcile with Koneko but Kuroka feels that she did something horrible to her sister even if it was to protect her as she was blamed by many Devils and was even nearly executed. Issei reassured her that he would help the two sisters patch up their relationship when the time comes, adding that Koneko's smile was the most important thing to him. Kuroka finally understood the reason why all the girls around Issei were falling for him, claiming that he was more charming than normal handsome men. She was later absent during the attack of Khaos Brigade due to Vali calling her and Le Fay back to assist him with his own battle.
