Jita Phrygianos

Eleventh of the Adepts, known as Black Diamond, she is Joshua's sister, whom she treats as a fool. Her element is carbon, from which she can create bladed weapons; either form it as a pair of crescent-like scythe or fiber thread; at will. She was initially very harsh towards Tomo, addressing her as a loose woman due to her good looks, though she apparently developed a crush on her, slowly opening up, especially after Tomo saved her when Georg Tanner forced her to take the blame of a fight he had provoked. She joins Wan Chen in his attempt to take the Magdalena of Thunder and was thought dead after performing a suicide attack to kill Katja in the virtual world along herself. However, she survived and was retrieved by Athos, who fitted her with a special lock on her left breast that causes her excruciating pain should she feel either excessive pleasure or use her powers. Though uneasy at being well-treated by her "enemies," she has begun to open to the people at St. Mihailov.

Appearance
She is a very serious and quite smart character, a very powerful one, too. She wears something resembling either a white robe with a purple inner part, or simply a long lab coat, with black boots and somewhat a white and black maiden's shirt inside. She has short black ear-length hair, with a slight curly piece of hair slightly touching the collar of her wear, with reddish-brown eyes.
