Hatoko is invited to Jurai's house to make dinner for him and his sister, but gets downhearted when Jurai decides to stay at school to talk with Tomoyo about her writing. Hatoko gets angry at Jurai when he refuses to tell him what he talked about with Tomoyo and snaps at him, going on a rant about how she just can't understand his chunibyo behavior before running off. As Jurai goes off in search for Hatoko, he worries that he might have been putting stress on her the entire time, but Tomoyo slaps some sense into him and helps him search. Meanwhile, Hatoko comes across another Chunibyo, who teaches her not to worry about not being able to under chunibyo, before using his own power to knock Hatoko unconscious. With Jurai having no luck in finding Hatoko, Sayumi decides to bring her Root of Origin to the next stage in order to find her. (Source: Wikipedia)
