My name is Miyanaga Rikuto. I'm a second-year high school student, and I'm single. I, who have absolutely no experience with girls, gained stepsisters this spring. And... five of them?!
The eldest daughter, Chika, hates men, while the kind-hearted second daughter, Mizuo, and the trendy third daughter, Karin, are twins. The fourth daughter, Fuka, is a young lady with a secret, and the youngest, Sora, is a spoiled brat! Our sudden cohabitation has turned into a chaotic life full of troubles!
I'm starting my "big brother life" with my five stepsisters, each with their own unique personality!
