オリヴィア・ニーデルマイヤー

A Knight dispatched by the church to Vanaheim island with orders to uncover the truth of Alice's Legacy and prevent Mahou Shoujo Lyiene from obtaining the Legacy. She obeys chuch teachings unquestioningly, and like the church sees no difference between the Witches and the Magical Girls who rebelled against them.

 An experienced adventurer who has no qualms sleeping in the inn stables, much to Monica's delight. She is hostile to Lyiene and eventually challenges her to a duel as they are not on church territory and she is thus unable to arrest her for heresy. 

After losing to Lyiene in the duel she vows to reach the dungeon's depths before Lyiene. However, she is unable to defeat the Dryad in her weakened state and ends up being raped and losing her virginity. Lyiene saves her and Olivia reluctantly acknowledges that Witches and Magical Girls shouldn't be tarred with the same brush. 

Olivia eventually acknowledges she is not capable of overcoming the dungeon's challenges and remains in the island settlement. 

After Lyiene overcomes Alice, Olivia stays on the island to report her findings to the church after further investigation of its depths. She finally acknowledges Lyiene as a friend and vows to write a glowing report of the contributions of the Magical Girl in the demise of the final Witch. /
