Description
Jita Phrygianos, codenamed "Black Diamond," holds the position of Eleventh among the Adepts. She openly derides her older brother, Joshua Phrygianos, viewing his perceived incompetence and elemental affinity as a family disgrace. However, she reacts defensively if others disparage him, reserving that right solely for herself. As an Adept scientist, she examines Tomo Yamanobe's body due to the dormant Qwaser of Gold within it, developing an intense fascination, particularly with Tomo's breasts, though Adept rules forbid physical contact with the guest host.

Physically, Jita possesses neck-length black hair with slightly messy strands brushing her coat collar and reddish-brown eyes. At 15 years old, her exact bust, waist, and hip measurements remain unrecorded. Her attire combines a high-collared white coat resembling a lab suit over a short maid-like dress, black leggings, and heeled boots. She demonstrates heightened agility, leaping over St. Mihailov Academy walls during an escape attempt only to collide with an invisible barrier.

Her personality blends stern loyalty to her mentor, Wan Chen, persisting even after his betrayal, with flustered awkwardness, especially when faced with nude females. Initially, she harshly judges Tomo Yamanobe as a "loose woman" based on appearance, but this transforms into a crush after Tomo defends her from false accusations orchestrated by Georg Tanner, who forces Jita to take blame for a provoked fight. This event softens Jita, prompting her to slowly open up to others at the academy. She exhibits gentleness in her protective relationship with the timid Milk, who rarely leaves her side. A defining trait is her androphobia—an intense aversion to male touch causing severe trauma if violated.

As the Qwaser of Carbon, Jita manipulates carbon atoms to form bladed weapons like crescent scythes or ultra-thin, durable diamond wires, techniques visually reminiscent of the Phoenix. She hardens her fingernails for close combat and leverages Earth's abundant carbon for versatile material sourcing. Limitations include diamond constructs shattering under stress due to their crystalline structure and difficulty countering non-physical attacks like gases, radiation, or liquids. While not yet a master of her element, she shows steady progress in the manga.

Internal conflict arises within the Adepts: Georg Tanner distrusts both Phrygianos siblings, deeming them inferior, and her fixation on Tomo breaches conduct rules, straining her relationship with Wang Xien. She favors big breasts and hot springs but dislikes Alexander "Sasha" Nikolaevich Hell. She performs poorly in activities like bowling. A manga gynoid is named "Jita II" in her honor.
