Tenchi Muyo! - S02

Masaki Tenchi was an ordinary boy, except for one thing: he was the heir to the Masaki Shrine. But then he breaks the seal that was supposed to keep a "demon" sealed away inside a small shrine in the back, and he ends up having to fight the revived Ryoko, the demon. Once Ayeka realizes her rival Ryoko has been revived, she comes to Earth too. And that is how Tenchi's entanglement with the rulers of the galaxy, the Jurai clan, began.
