Kazuki’s family runs a café. However, recently their customers have started leaving them for a newly opened maid café in the neighborhood. Thus Kazuki’s father decided: “We must compete and start cosplaying as well.” Luckily for him his wife and daughter were quite beautiful and had no problem wearing various costumes while serving customers.Thus he went and bought a pile of costumes and ordered Kazuki to help his mother and sister with training for their new roles and to take over their new management.
