Kodachi Kuno / Obsessed "Girlfriend"

Known as "The Black Rose" in the gymnastics community due to her signature theatrical style of exiting a scene by leaving behind a swirling trail of black roses accompanied by high-octave laughter.

As a master of Martial Arts Rhythmic Gymnastics, she often preemptively attacks her opponents with various weapons, including swords or a giant mallet to cripple them, thus winning by default. She calls it "fighting in all fairness before the match." When these failed, she has also resorted to the use of more devious methods, once attempting to shake her foe's hand with thumbtacks between her fingers. She is especially fond of using paralysis gas and sleeping powders on people, even when she has no apparent motivation to do so.

Kodachi is very agile, and she is not averse to using unorthodox methods in combat such as rigged weapons, explosives and various poisons.

She is a good cook who prepares elaborate meals, and she often uses culinary expertise to her advantage by placing poisons, toxins, serums, and other strange substances in her victims' food to attain something she wants from them.

Kodachi is sometimes referred to as a “beautiful but unfortunate” girl because of her strange behavior.

She loves elegant romantic stories and dreams of a loving fantasy like relationship.

She has surprising skills like creating fake photos to embarrass others.

She even uses strong medicines to get what she wants in love, which even her brother finds scary.

Kodachi is smart, skilled, and good-mannered, but she is also really strange and acts in ways that make others uncomfortable.

She is very persistent, sneaky, and can get really obsessed with her goals, especially when it comes to love.

Despite all this, when she loses in a fight, Kodachi can admit defeat honestly.
