Princess Resurrection

Adapted from Mitsunaga Yasunori’s manga serialized in "Monthly Shounen Sirius", the story follows Hiyorimi Hiro, who moves to a new city to live with his older sister-only to die before he can reunite with her. He awakens as a servant to a princess from the Monster Realm, who, by chance, has hired his sister. As a contender for the throne, the princess faces constant threats from monsters, forcing Hiro to defend her with his life-even if it means dying over and over again.
