Rengoku and Mitsuri (BWL)

Mitsuri: 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.

Rengoku: Kyojuro was greatly enthusiastic in regard to his duties as a Hashira, and often came across as cheerfully eccentric. He was amiable, pure of heart, and boasted extraordinary technique and swordsmanship stemming from strict practice and discipline. He was an honorable warrior who adhered to his code of morals and principles that was instilled into him by his mother at a young age; the most significant being his belief that those who were born strong have a duty to protect the weak.
