Shinju no Nectar神呪のネクタール; Nectar of Dharani

Sakra, the last surviving princess of a fallen kingdom, is being hunted down for the power of Ambrosia she possesses - the ability to grant divine strength, but only to a human. With no human companion, she decides to summon one from another world in a desperate attempt to find a knight to protect her, but the man who answers her call is less than what she had hoped for.
