Below the blouse, her stomach is covered by a slightly thicker adornment with intricate artwork, highlighting the attention to detail in her attire.

On her back, Kohina wears a piece of clothing that functions as a sheath for her double blades, a practical and functional aspect of her outfit.

Kohina from Black Bullet exhibits a complex personality, heavily influenced by her father’s cruel and unrelenting nature. She shares his ruthlessness, often displaying a cold and calculated demeanor as she annihilates those who stand in her way without remorse. However, Kohina’s actions occasionally reveal an inner conflict, especially when it comes to taking someone’s life. This is evident when she questions her father about whether she should kill Rentaro Satomi, who had threatened them at the time. Later, she repeats this hesitation with Enju Aihara, indicating that while she is capable of cruelty, there are moments where she grapples with her actions.

Her vengeful side is another prominent aspect of her character, particularly when she targets those who have thwarted her plans or saved individuals she intended to harm. When such events occur, Kohina loses her composure, badmouthing her opponents and calling them weak in a fit of rage, showcasing her emotional volatility in the face of failure.

Despite her predominantly cruel persona, Kohina is not entirely devoid of emotions. Her reaction to Rentaro’s apparent death after Kagetane’s defeat reveals a more vulnerable side to her. Kohina bursts into tears, saddened by the loss, showing that beneath her cold exterior, there are still emotions at play. This mix of cruelty, vulnerability, and inner conflict makes her a layered and unpredictable character in the Black Bullet series.
