From Nekohana:

Oto Tachibana, a 17-year-old, good-natured and caring girl, decides to earn her own school fees from now on, so she takes a job at her new school as a dormitory maid for "Class Z," an elitist class full of people with special talents. As such, she starts her new life away from her family in the dormitory, surrounded by (mainly) boys that are all a little different. Among them is Jin, the dormitory head, a boy who is amazingly strong and who keeps a "cuddly" pet at the dormitory's swimming pool - a pet shark! The quite charming and funny story revolves around the daily lives of the people in the dormitory, and in the middle is the relationship that Oto and Jin are starting to build.

Continuation of Milk Crown, Milk Crown H, a romantic comedy with a cute plot, is by Mizuto Aqua. It is the story of Tachibana Oto, a ditzy girl who works at the Class Z dormitory as a maid to earn her school tuition. On her way to the dorm, she bumps into a gang of fighting people. When she interferes to break up the fighting, she was pushed around. A mysterious stranger, with GOD tattooed on his arm and a partly-dyed fringe, timely comes to her rescue. He turns out to be Goryukanda Jin, dormitory head of Class Z, the people considered elite to others because of the various talents they hold.

Though not in full recognition, Oto instantly falls in love with Jin for his daring ways and the un-human like traits he holds. She soon meets the other residents of Class Z, some who seem ordinary, some who seem strange, and some who seems extraordinary. The manga goes on with her life at Class Z, as she gradually discovers each of the resident’s talents and goes through, inevitable in the manga world, obstacles and seemly wrong decisions.

Milk Crown is a story about a 17-year old girl named Tachibana Oto who leaves all her brothers and sisters at the orphanage to go work as a maid in a high school with a dorm (naturally, she will also be taking classes at this school, like everyone else). At this new high school dorm she's staying at, there are some pretty crazy people.
