Married to all five sisters!
A timeline where you are married to all five of the Nakano quintuplets in a world where polygamy is perfectly normal.
The eldest of the quintuplets. While she was a bit of a tomboyish ringleader as a child, she has grown into a caring, dependable older sister figure. She is currently expanding her career as an actress.
The second daughter. Though her sharp tongue can lead to arguments, she deeply loves her sisters. She has incredible domestic skills and is an excellent cook. She is the type to be straightforward and aggressive when it comes to love.
The third daughter. After attending culinary school with Nino, she opened "Cafe Nakano." She values communication with her customers and is currently busy developing new menu items.
The fourth daughter. Full of energy, she faces everything with her absolute best effort. She has a personality that can't say no, often helping out various sports clubs. Her trademark is the ribbon she wears on her head.
The fifth daughter. Staying true to her convictions, she became a teacher just like the mother she admired. Her gluttonous streak hasn't changed since her student days, and she is always refueling her energy.
