Tenchi Muyou! Ryououki 5th Season

Except for the fact that he was the Masaki Shrine's successor, Masaki Tenchi was an entirely ordinary young man. However, he ends up destroying the seal that was intended to keep a "devil" confined inside a tiny shrine in the back, and is thus compelled to engage in combat with the resurrected Ryoko (demon)! Ayeka visits earth after learning that her foe Ryoko has been reborn. And thus is how Tenchi first came into contact with the Jurai clan, the galactic ruling family.
