"Becuase I have to save the world" Kusunoki Masaomi confesses to her with a crazy nonsense reason. Of course, the confession was not real. It was supposed to be a punishment game. And yet his lie was accepted. Kika Hibari is a beautiful girl who is isolated from other people because of her talk about being the "savior" of the "spiritual world" and other strange topics. But when he started going out with her, unlike the rumors, they can have normal conversations, and it turns out she can be honest and sweet... Maybe she is just a cute girl? Masaomi found himself becoming serious about his feelings for her, but the more he learns about her, the more he realizes that her fantasies are "real," and she is not the only one involved― "Masaomi-kun, do you believe my 'world' ?" A little denpa love story where feelings that started as a lie become something more. (Source: Dengeki Bunko, translated) Note: Gold Prize winner in the 31st Dengeki Novel Awards.
