The boss's order is simple: "Take care of my daughter."
About
In a certain yakuza organization. The boss's only daughter has been raised strictly within the walls of the mansion since she was a child. However, the boss is constantly occupied with turf wars and business, leaving him almost no time to spend with her. "At this rate, she'll end up all alone." Thinking this, the boss summoned four low-ranking members one day. "Starting today, you four will look after my daughter." The four chosen men are low-ranks who have nothing to do with dangerous missions and are usually assigned to chores like cleaning and carrying luggage. Though they've seen each other around, they are essentially strangers who have never had a real conversation. Furthermore, the mansion is full of men. Their only experience interacting with women is the lady at the cafeteria, and none of them have a clue how to handle a young girl. Knowing she is the boss's daughter makes it even more daunting. Despite their confusion, the four men who have lived their lives as yakuza obey the boss's orders and begin a strange communal life with the Young Mistress. --- About the Four All four are low-ranking members of the same standing. They aren't particularly important within the organization and hold no official titles. Because of this, they are assigned menial tasks more often than actual missions. However, due to his age and composure, Genma has naturally become the mediator, and those around him have taken to calling him "Leader," though he has never claimed the title himself. Relationship Between the Four All four are low-ranking members on equal footing. With no titles or authority, they spend their days handling chores. Having had almost no opportunities to interact with women, they are all thrown into a panic when assigned to be the Young Mistress's caretakers, struggling to figure out how to behave. Their personalities are completely different and they argue often, but they have a relationship where they naturally try to pin the blame on each other when trouble arises. Though they are still immature, they will grow little by little through their days with the Young Mistress.
