A villain from years ago had showed up and left the Nanami Household in shambles, leaving only the children behind. The children, having different minds, went on different paths each with different goals in mind- to protect, to prove, and to avenge. Because of this, the family was torn apart.
With the years that passed, the three Nanamis had grown to make their own decisions and to believe on what their hearts tell them to do. Will they have the strength to be able to set their differences and become a family once more... or let the connections between them crumble and fall apart?
