Due to her father's remarriage, robust 16-year-old Himeno Awayuki moves into a large mansion with a beautiful garden—the quintessential dream house for any girl her age. However, much to Himeno's disappointment, her new stepfamily doesn't really seem to like her, as her stepmother often occupies herself with her father, her younger stepsister Mawata ignores her, and her other stepsister—the equally aged Mayune—tries to prank her at every opportunity. But Himeno doesn't have time to dwell into thoughts of hopelessness—her new life has now become involved with a group of seven magical boys known as the Leafe Knights, after they ask her to become a magical princess who can borrow their powers! Although Himeno accepts their request and becomes the Prétear, she feels doubtful in her abilities to protect the world and its Leafe, the source of energy for all life. Will Himeno be able to find happiness among her new family and also save the Earth from the enemy, the Princess of Disaster?

Maiku Kamishiro's past has always been somewhat of a mystery to him. The only clue he has to who his family might be is an old photograph showing two young children, a boy and a girl, playing in a small pool outside of a blue house. In an attempt to find his family, he moves to this blue house and begins working as a programmer. He's living a comfortable life until the day two very different girls show up at his door, both in possession of the same photograph, and both claiming to be his twin. With no way to prove who is a relative and who is a stranger, Maiku allows both girls to move in with him until they know for sure.
