Keroppi gets blamed for something he didn't do, runs home crying, and gets struck by lightning that throws him into the exact fantasy world from the movie he was watching, except now the stakes are real and the cowardly prince beside him needs to learn what courage actually costs. This is a show about two characters who are afraid, who have every reason to stay afraid, and who choose to move forward anyway. By the end, you understand why a scared frog and a scared prince had to meet in another world to learn they weren't alone.
Keroppi's day takes a dark turn when he gets blamed for chaos he didn't cause during a movie screening. Humiliated and upset, he bolts from the theater only to be struck by lightning that zaps him straight into a fantasy realm that mirrors the film he just watched. There he encounters a timid prince who's spent his whole life hiding from conflict, content to let others make his decisions. Thrown together by circumstance, Keroppi and the prince embark on an unexpected journey across a magical landscape. Both characters carry the weight of their own insecurities: one deals with being falsely accused and dismissed, the other struggles against the expectations placed on him to be brave. Their adventure becomes less about slaying monsters or saving kingdoms and more about discovering that courage isn't the absence of fear. It's about standing up for yourself when it matters, owning your choices, and refusing to let the world define you by your mistakes. This heartfelt fantasy OVA combines childlike wonder with surprisingly genuine emotional growth.
