Yuta has a problem. As one of the thousands of Japanese students afflicted with "chunibyo," a state where they're so desperate to stand out that they've literally convinced themselves that they have secret knowledge and hidden powers, Yuta spent most of his middle school years living in a complete fantasy world. But that's not his major problem now, as with a lot of work and effort, he's finally managing to overcome his delusions to the point where thinks he's ready to start high school with all his cards in order. No, his BIG problem is the girl he first encounters climbing on his balcony. It seems that his own efforts to rid himself of his chunibyo have attracted the attentions of another sufferer, and she's decided that this makes him her soul mate. And since Rikka's just moved in upstairs, now he's being sucked into her fantasy world! Can a formerly wild and crazy guy handle being the focus of a completely delusional girl? Or will his own chunibyo return with a vengeance?
Yuuta and Rikka are in their third year of high school. One day in Spring, Touka declares that she will take Rikka to Italy with her, as her job has stabilized there and thinks they should migrate together as a family. Touka is also worried about Rikka not being competent enough to advance to universities in Japan. The gangs from the club suggested Yuuta, who doesn't want to be separated, to elope with Rikka!! A runaway drama throughout Japan begins.
Summary of the first season of the show, as seen from Rikka's perspective with new elements.
