One day, an un-named ordinary high school girl (her name is left to your imagination), met Cheko, a maid sent forth from a village of maids. Cheko the maid can melt, fly, remove her head and violate physics. Surrounding "Ordinary high school girl" and her strange little maid are yuki-onna's who hate cold, cute squid that can speak, moe yankees, tsundere maid assasins, ecchi lesbian teachers, trap yuki-otoko's, gentlemenly yakuza and many more.
