Yousei Ningyo Shoujo Kurumi
妖精人形少女くるみ
Kurumi turns to her fairy tale book when feeling sad and lacking courage. One day, a being named Chestnut emerges, identifying herself as a "Coppelia" from a fairy world, having arrived through a portal created by Kurumi's intense longing. With Chestnut now by her side, Kurumi finds herself drawn into confrontations where participants compete in battles that result in the loser being stripped of their clothes.
