Nakano Nino is the second daughter among identical quintuplet sisters, along with Ichika, Miku, Yotsuba, and Itsuki. When they were five years old, their biological mother passed away. They were subsequently adopted by Maruo Nakano, a wealthy yet perpetually busy hospital physician who serves as their stepfather and legal guardian. Academically, Nino and her four sisters struggled significantly with their studies, facing severe academic setbacks and repeating a school year before transferring to their current school.
​Currently, Nino and her sisters live independently in a high-end luxury apartment provided by Maruo. Having endured past hardships together, Nino developed an intensely deep bond and an overprotective stance toward her sisters, placing their family's unity above all else. As a result, she maintains a fiercely defensive demeanor—acting sharp-tongued, cold, and deeply distrustful of any unfamiliar males or outsiders attempting to enter their personal circle.
