However, Ichijou observes that she's free from malice, and avoided all the time trying to seriously hurt him. He compares her to a typical tomboy.

Despite such carefree and sarcastic personality, Mukuro is extremely loyal to her friend Annabelle and a reliable partner and bodyguard, making her also a hard and almost implacable foe, such part of her personality reflected on her sacred gear, as she's able to create imaginative and several demon swords in order to counter possible threats.
