He is My Master, Vol. 1

He is My Master follows the day-to-day life of Yoshitaka, a sex-obsessed 14-year-old with a major superiority complex and a uniform fetish to boot. After his parents die in an accident, Yoshitaka inherits the family fortune—and the family estate. Deciding that the musty old place needs some livening up, he fires the staff, intending to replace them with attractive, live-in maids. His dreams more than come true when three sexy girls—along with their pet alligator, Pochi—lay claim to the jobs.

He is My Master is a popular ongoing manga in Japan from Square Enix, the publisher of Full Metal Alchemist. It is also a popular anime that aired on Japanese TV in 2005.
