My name is Mio Satonaka. As the second daughter, I am currently focusing on bride training in preparation for my upcoming marriage. My older sister, Kaori, is a fashion model actively working in magazines and advertisements, leading a very busy life. Meanwhile, my younger sister, Kiyomi, has just started working as a teacher this year at Kusunoki Girls' Academy, adjusting to her new environment. With each family member occupied with their own responsibilities, I am further dedicating myself to perfecting my bride training.
