Because their father doesn't let them keep the alligator Pochi for a pet, sisters Izumi and Mitsuki Sawatari run away from home. However, they soon run out of money and need a place to stay, so they visit the rich boy Yoshitaka to ask him for help. He offers to hire them as maids, but Izumi thinks the terms (tight and revealing maids' outfits) are unreasonable and decides to leave, knocking down a vase on her way out. This is exactly what Yoshitaka expected; he demands to be paid a ridiculously large sum for the item, knowing the girls can't pay.

Now, the girls are forced to work for the boy and live in his house, while he keeps adding to Izumi's debt. In addition to this, Yoshitaka is rumored to have a lolita complex and Pochi (who turns out to be a perverted alligator) keeps chasing Izumi around while she's in her maid uniform, increasing the debt due to breaking things around the house.
