スレーブ・ラピス

"Poisonous thorns devoted to the Lord!!" Having achieved perfect compatibility with Knight Gear, and obtaining the power of a Magical Girl that she has always dreamt of, Lapis has fulfilled her long-held wish. However, as a result, her female slave transformation has accelerated, and she now trembles with fear and even enters heat simply by catching a glimpse of the root of her past trauma, Kai Haibara. Despite this, Lapis, with her high pride, rallied herself and challenged Haibara bravely, only to suffer a humiliating defeat at his hands. Fascinated by Haibara's terrifying and ferocious nature, she became completely subservient to him and was reborn as a new utterly servile evil female slave, Slave Lapis. Her once lively, proud and radiant smile has changed to a power-drunk, vulgar and wicked one towards all those who oppose her master and her... an arrogant expression reminiscent of her new master.
