Mercelida Ygvar  

Mercie, メルチェリーダ・ユグヴァール

The mother of Lotte. Mercelida is extremely promiscuous, even for a succubus. She once slept with a man from her harem while Lotte (who was 5 then), was in bed with her. This is slightly changed in the anime, so that instead of the man coming uncalled when Lotte was already in bed with her mother, he came when Astarotte was heading to her mothers room, so that her mother did not know she was there. The shock of this experience is identified as the origin of Astarottes hatred toward men.
