Background & Current Information
Created for the purpose of exterminating the Divine Corpse Fragments, she was sent in from a different world along with her inactive power plant that has been sleeping for several thousand years in this world; Oruto considers her a sister. She lost the memory of her original mission and she was thought to be some ancient Armored Golem by Amelia’s group and taken in as a party member.
By the way, even if she didn’t manage to obtain her very beautiful body Tooru was 100% serious about having "sex" with her and keeping his promise to her. As a result, he already researched in the Black Market of Paravata City for a "magical living product" that was capable of being equipped on a living being like an Armored Golem and attached as a sort of sex sleeve.
The way she addresses Tooru is: Goshujin or (Master)
