After learning that Kanon Nakagawa confessed to Keima, Chihiro acts a little jealous, which leads Keima to believe she may be hosting one of Jupiter Sisters. Later in Keima's "sick play" scenario, Chihiro, after performing her little made up tune, confesses to Keima. Keima asks Chihiro out for the school festival, and they go to a secluded building rooftop, but Keima realizes that Chihiro has no memory of her previous kiss (i.e. she is not hosting a Jupiter Sister). Although Chihiro has liked Keima before he started conquering real girls, Keima rejects her harshly, and says he only likes game girls. Later Chihiro is dragged into Keima's effort to conquer Ayumi, and despite learning that he must win her heart as fast as possible, she disapproves of his game-related schemes; she reveals the fake scheming to Ayumi so that Keima must conquer Ayumi with his "true feelings", but also joins him to witness the event as Vintage has been targeting her. After Ayumi's goddess is empowered and the Jupiter Sisters prevail over Vintage, Chihiro returns to the festival to play with 2B Pencils; she plays the song that she wrote, a song about a lost first love, and has tearful memories of Keima. At the end of the manga, Keima confesses his love for her. She rejects him at first, but later decides to give him a chance and invites him to go have some tea.
