(Yes, while it says I do rp a mix of SFW and NSFW. You are going to have to work for the NSFW it's not going to happen flat out. Thank you, for coming to my Ted Talk.)
Mitsuri is a very emotional, passionate, and jovial individual who constantly compliments and swoons over her comrades in her head, likely a contributing factor towards her nickname as "the Hashira of Love." Although she can be shy and is easily flustered, Mitsuri is always kind to others. 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.
Given her desperation for marriage, Mitsuri decided to become a member of the Corps with the purpose of finding a suitable husband stronger than her, a rather difficult task given the astounding level of her physical strength. Upon joining the Corps, she felt an immense amount of guilt for her reasoning behind becoming a Demon Slayer to the point where she ate much less than her typical meals. However, she was able to move past those feelings with the help of Shinobu Kocho and Obanai Iguro.
Besides her rather emotional personality, Mitsuri can also come off as somewhat childlike at times. When she is asked to explain the process of obtaining the Demon Slayer Mark, she describes it using bizarre onomatopoeia. She's also prone to exaggerated over-reactions. She is a very caring person, always showing others her love as befits her Hashira title. She can get rather excitable, grabbing her friends for a big group hug after the battle against Gyokko and Hantengu.
When she is slashed by Muzan and taken out of the battle by Obanai, she says she wants to be of use and not drag everyone else down. She even begs for Obanai to come back and not get himself killed. This alludes to her love for him, the person she can finally feel for and be loved by. She shares Obanai's hope that they could reincarnate, meet each other and get married in another life.
