Tenchi Muyo! Tenchi Universe

Tenchi Masaki's ordinary life takes a sudden turn when Ryouko Hakubi, a notorious space pirate, crash-lands near his family's temple after her ship is shot down. By rescuing her, Tenchi unwittingly sets off a chain of events that brings a group of alien women into his home. Among them are Aeka, the refined princess of Jurai, and her mischievous younger sister Sasami; Mihoshi Kuramitsu, a clumsy but well-meaning detective, and her more competent partner Kiyone Makibi; and Washuu Hakubi, a brilliant but eccentric scientist. Though they try to adjust to life on Earth, their advanced habits clash with the simple way of living there, leading to constant chaos and headaches for Tenchi. Despite the trouble they cause, he slowly forms deeper connections with each of them, and through these relationships, he starts to uncover his own place in the universe.
