"Even if we suck at soccer, we still have maid cafés...!"

Battles are fought between the maid cafés to determine which one is the best at serving their masters, and they are all aspiring to be like the supreme maid and waitress (which is an anime character), Minori-chan! Kamagaya Misaki is close to achieving that goal - all she needs is Minori-chan's original maid uniform, which is rumored to exist in real life! However, it seems that the secret behind Minori-chan and her uniform is...?
