Kodachi Kunou

The captain of the gymnastics team of the St. Bacchus' School for Girls, who is referred to as "The Black Rose," likely due to her signature theatrical style of exiting a scene by leaving behind a swirling trail of black roses accompanied by high-octave laughter.

Kodachi is an expert in Martial Arts Rhythmic Gymnastics, making her skilled in acrobatics and the use of balls, clubs, hoops, ribbons, and ropes as weapons. She is very agile, and she is not averse to using unorthodox methods in combat such as rigged weapons, explosives and various poisons.
