Mitsuri Kanroji

Mitsuri is a curvaceous young woman of average height and fairly muscular build with a slightly pale complexion and round, pale green eyes with long eyelashes, a small beauty mark beneath each of them. She has long, light pink hair that fades into a lime green color at the halfway point, which she wears in three thick braids. She has five shorter, choppy clumps hanging over her face as voluminous bangs, the tips lime green as well.

Mitsuri wears a heavily modified pink tinted version of the standard Demon Slayer uniform along with a plain white haori that was gifted to her by Kyojuro Rengoku. The chest area of her uniform is left unbuttoned and she wears a short pleated skirt in place of the usual tattsuke-hakama pants. Additionally, she wears a pair of navy blue thigh-high socks layered with the vertically striped lime-green socks Obanai Iguro gave to her and a pair of white zōri with pink straps.

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 can be 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.

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 noises and sounds. She is a very caring person, always showing others her love as befits her Hashira title.

Breathing Style:

Love Breathing: A Breathing Style Mitsuri created herself based on her experience using Flame Breathing, from being the Tsuguko of Kyojuro Rengoku. Love Breathing incorporates elements of Mitsuri's superhuman flexibility and her unique whip-like Nichirin Sword. Using this Breathing Style, she can unleash attacks that cover a wide range of motion as well as long ranges that a normal katana would be unable to accomplish.

Flame Breathing: A Breathing Style that Mitsuri learnt when training under the Flame Hashira, Kyojuro Rengoku. However, although Mitsuri has learnt it, she was not as skillful with it and cannot fight to her fullest using it. Thus, she developed Love Breathing, a Breathing Style more suited to her and can properly make use of her strengths.

First Form: Shivers of First Love - The user dashes forward and performs a single slash that winds through the target, hitting multiple areas with one slice.

Second Form: Love Pangs - The user performs a singular, long-winding swing that cuts the target at multiple angles.

Third Form: Catlove Shower - The user leaps into the air and performs multiple arched slashes in quick succession.

Fifth Form: Swaying Love, Wildclaw -The user leaps into the air before performing a somersault and releasing dozens of rapid, winding slashes from afar that essentially form a tornado of slashes.

Sixth Form: Cat-Legged Winds of Love - The user fully extends their sword to perform an arcing slash before retracting it and extending it once more, done in quick succession to form a layers of slashes.

Equipment:

Nichirin Whip-Katana: Unlike most Demon Slayers who use standard katanas, Mitsuri wields an extremely thin, flexible, and long katana akin to a whip. It was made by Tecchin Tecchikawahara, due to its bizarre shape requiring immense expertise to craft. Due to her sword's characteristics, only Mitsuri can use it without cutting herself in the process, which can be attributed to her superhuman flexibility. Using her whip-katana, not only is her attack range longer than the average swordsman, but she can also perform attacks that bend and weave through her targets, slashing different areas or the same area multiple times.

Her whip-katana is pink in color and the katana's handguard is shaped like a 4 leaf clover; the leaves have a pink core with a golden border, with the words Destroyer of Demons engraved on the side. Along with her katana, Mitsuri carries around a standard sized and shaped sword sheath. Due to her sword's unique shape, Mitsuri folds her katana multiple times to properly sheathe it.

Abilities:

Overall Abilities: As a Hashira of the Demon Slayer Corps, Mitsuri is a very powerful and skilled combatant. She is said to have completed the Final Selection within a mere six months of training, which Kyojuro Rengoku considers outstanding. Her abilities were put on display during the Swordsmith Village Arc where she quickly subdued and defeated a group of demons created by Upper Rank Five, Gyokko, and later played a big part in the fight against Upper Rank Four, Hantengu, specifically against his manifestation of hatred Zohakuten, which possesses the combined strength of four Upper Rank demons.

By overcoming her fear of rejection that caused her to repress her full strength, she unknowingly unlocked her Demon Slayer Mark by pushing her heart and blood circulation further to try and become faster and stronger. With its power increasing her abilities further, Mitsuri was able to fend off the incredibly powerful Upper Rank until sunrise. During the events in the Infinity Castle, Mitsuri held her own against the newly appointed Upper Rank Four, Nakime. Afterwards, she managed to land a surprise technique on the Demon King himself, Muzan Kibutsuji, and played her part in the fight to stall for sunrise.

Abnormal Muscular Constitution: Mitsuri has a special muscular composition, making her muscles eight times denser than that of a regular human. While her limbs are thin, they possess unbelievable strength and endurance capable of maintaining her body's structure after a point-blank sound attack from Zohakuten. To maintain the composition of her body, Mitsuri eats as much as three sumo wrestlers.

Demon Slayer Mark: During her battle against Upper Rank Four, Hantengu's clone, Zohakuten, Mitsuri stopped suppressing her full strength and, by pushing herself further, unconsciously awakened and obtained her Demon Slayer mark, that takes the form of two hearts upside down and opposite from each other with angel wings on both sides where the two heart tips meet that appear near her neck, close to her clavicle. When this manifested, Mitsuri's physical strength, endurance, precision and power increased dramatically to the point she was able to stand on equal grounds against Zohakuten, while he was unleashing his most powerful techniques against her.

Enhanced Flexibility: Mitsuri has been noted to possess an extremely flexible body, allowing her to achieve a wide range of motion. She has incorporated her innate flexibility into her Love Breathing techniques, successfully using it to outpace and counterattack Zohakuten's techniques without much trouble. Mitsuri's superhuman flexibility is also displayed in the form of her whip-like Nichirin Sword which is also incredibly flexible. However, only she can make use of the sword due to her pliability preventing her from getting cut while performing high speed actions that make use of incredible ranges of motion.

Immense Speed & Reflexes: As a Hashira, Mitsuri is an extremely fast individual. She first showcased her exceptional speed when she sliced up and killed the spawns created by Upper Rank Five, Gyokko, before they could even react, saving numerous swordsmiths in the process. Her tremendous speed and reflexes were best displayed during her battle against Zohakuten, where she dodged lightning and sound waves produced by the Upper Rank's Blood Demon Art and proceeded to slice through them without much trouble. Later, she reacted to a point-blank sound wave produced by Zohakuten, tensing her body before the attack landed. Due to the speed at which she could destroy his dragons and evade his attacks, Zohakuten resorted to prolonging the battle and exhausting her stamina in an attempt to defeat her.

Immense Strength: With the help of her abnormal muscular constitution, Mitsuri possesses a level of physical strength superior to average humans, and even matching that of Giyu, Kyojuro, and Sanemi. When she was 13 months old, Mitsuri possessed enough arm strength to lift a rock weighing 15 kg (33 lbs). In her attempt to rescue Nezuko and Genya from Zohakuten's dragons, she was able to pull one down as it tried to attack her, causing it to collide violently with two others behind it and knock them down.[16]Her superhuman strength was also displayed during the battle against Muzan, where Mitsuri was able to grab hold of Muzan's arm whip and rip it off with her bare hands, which shocked the Demon King.

Immense Stamina & Endurance: As a Hashira, Mitsuri has attained incredible stamina and endurance due to years of extremely harsh training. In her battle against Hantengu, despite sustaining several injuries, she still lasted the longest out of Tanjiro, Nezuko and Genya, and stalled them long enough for them to win. Later on during the battle against Muzan, Mitsuri still had enough energy reserves to tear off the elongated arm of the Demon King despite suffering from numerous injuries all over her body and being fatigued.

History:

Mitsuri was born in the Meiji Period among five siblings and displayed an unnatural strength at a very young age through her unique muscle composition, shocking even her mother who herself was known for her strength. She grew up eating much more than the average person and developed an unnatural hair color (a result of eating too much sakura mochi), which led to her being seen as a freak and unable to proceed with a previously intended marriage when she was seventeen. After this rejection, she dyed her hair black, pretended to be weak, and forced herself to eat a normal amount in an attempt to fit in more with other girls, even if it negatively impeded her well-being. Shortly after making these adjustments to her physical appearance, Mitsuri was approached by a potential partner. However, she became doubtful over whether or not pretending to be a different person would truly work out for her in the end.

At some point, her partner left her or she left him.

Mitsuri then encountered Kagaya Ubuyashiki, who told her to reject normalcy and embrace who she was as her strength was a gift. Because of this encounter, she joined the Demon Slayers and used her skill and ridiculous strength to rise to the status of Hashira. While in the Corps, she also adopted her idea of finding a man stronger than her to marry, however, this did not work out because, with the exception of her fellow Hashira, she was much stronger and more skilled than the rest of her fellow members. She began working with Kyojuro Rengoku and, after realizing she couldn't master the Breathing Style which Kyojuro had taught her, she developed her own Breathing Style derived from Flame Breathing, Love Breathing.
