Kanou Kanata is a first-year high school student who, despite being a girl, admires princes and aspires to be one herself. While her older brother, Yotarou, is a doting, effeminate Judo Club captain, Kanata is completely unaware that Kyougoku, a delinquent who lives next door, has a crush on her. This is a daily-life romcom depicting a family of three siblings—Kanata, her effeminate older brother, and her responsible younger sister—as they are often thrown into chaos!
