She is a cold-hearted high school assassin who ranks fairly low in the assassin rankings she desires to get better at as a rookie at the game, who ends up allowing Satoko to live under her roof in exchange of benefiting her skills in getting points and help clean after the dead bodies, making her rank higher, while forming a partnership with the ninja.

Personality[]
Konoha can best be described as a ruthless but earnest girl with a slick set of skills and abilities that make her more armed in battle than believed by her looks. When a ninja is in sight to harm Satoko, she kills them without regret, showing great competence in her abilities and craft. However, she can also be lazy, as seen with her not willing to take care of the dead bodies prior to meeting Satoko that held her back in the rankings, or oblivious to what’s going on, with being unable to tell the difference between Satoko and Roboko when she was living with the latter. Despite her icy heart, she shows signs of joy and genuine expression, such as taking Satoko in or wanting to make sure she was okay in the night. Despite her indifference to Satoko, she does develop a strong bond as they start to spend time together in their everyday lives, though she rarely smiles to express happiness, only doing it when eating good food. In comparison to Satoko, she's less friendly and more trained at what she does.
