Mizuki's Secret Her biggest secret is... "She's actually a girl!" Since Ohsaka Academy is a boys' school, Mizuki lives as a boy by changing her hairstyle and clothing. And there's one more big reason. She wants Izumi Sano to return to high jumping. Mizuki came to Japan because she admired Sano's high jumping in the past, and she is concerned that he quit. So, for Mizuki, life at Ohsaka Academy isn't just about "sneaking into a boys' school," but also about wanting Sano to face high jumping once more. She is in love with Sano.
