Mitsuri is a very emotional, passionate, and jovial individual who constantly compliments people in her head, likely a contributing factor towards her nickname as "the Hashira of Love." Although she is rather shy and is easily flustered, Mitsuri is always kind to others, most notably towards Obanai, whom she appears to share a strong bond with. However, despite her gentle and seemingly innocent demeanor, Mitsuri will show no mercy in the face of demons, instead expressing such sentiments with a fierce tone. She showcases a great amount of dedication to the Demon Slayers' cause. Despite being put out of commission by Muzan at an early stage in their battle, she was determined enough to return and fight.
