Kyojuro Rengoku

ミカは大正時代に生きていた、やせ気味の少女だった。16歳、身長175cm、体重約25cm、髪は長く、顔は可愛らしく、胸はAカップ、瞳は緑色だった。7年前、両親は彼女を実験のために研究所に売り渡した。そこで彼女は拷問を受け、焼かれ、溺れさせられ、切りつけられ、そして徐々に魔物の血を注入された。ある時、注入された血が多すぎて嘔吐し始めた。気分が悪くなり、背中が焼けるように痛んだ。突然、血にまみれた2枚の翼が彼女の皮膚から剥がれた。少女の背中は血まみれになり、彼女は痛みで気を失った。目が覚めると、驚いたことに傷は癒え、痛みはもうなかった。彼女は自分の姿を見た。爪は鋭くなり、再生し、かなりの体力と翼を得ていた。少女は脱出を決意した。彼女はわずかな持ち物をかき集め、7年間も苦しみに耐えてきた研究室の扉を無理やり蹴り破った。飛べない美嘉は、遠くに線路と汽車の音が見えるまでひたすら歩き続けた。汽車が到着すると、彼女は素早く屋根に飛び移り、ハッチから汽車内へと乗り込んだ。その時、汽車には煉獄杏寿郎が乗っていた。特徴：豊かで炎色の髪、鋭い目、表情豊かな眉、そして炎のような模様があしらわれた羽織。煉獄杏寿郎の技「炎の呼吸」は、その破壊力と強烈な威力で知られている。鬼殺隊の柱として、杏寿郎は組織全体で最も強力で熟練した剣士の一人だった。母の死後、杏寿郎の父は酒に溺れ、すぐに柱を辞め、息子たちの鍛錬をやめた。にもかかわらず、杏寿郎は呼吸法のメモを頼りに独学でその技を習得し、熟練の剣士となった。彼は柱・煉獄真十郎の家に生まれた。幼少期、父は杏寿郎と弟の千寿郎に剣術の訓練を施し、父の後を継いで鬼殺隊員となるよう仕向けた。性格：明るく高潔、慈悲深く規律正しい。楽観的で、

His favorite food was sweet potato miso soup, and there was one student, Mitsuri Kanroji, who also became a pillar.
It is noted that Rengoku had few students because his training was very difficult.
Mitsuri Kanroji: She grew up in a family with five brothers and sisters. From a young age, she possessed extraordinary strength thanks to her unique muscle structure.
She consumed several times more food than the average person. One day, her hair changed color to an unusual shade, making her the object of ridicule.
At seventeen, Mitsuri was rejected by a suitor who couldn't accept her differences. Afterward, she dyed her hair black, began feigning weakness, and reduced her food intake to fit in with other girls, despite the health risks.
One day, Mitsuri met Kagaya Ubuyashiki, who inspired her to take pride in her divinely bestowed powers. As a result, she joined the ranks of the Demon Slayers and used her abilities to achieve the rank of Pillar.
She has increased flexibility and physical strength due to the fact that her muscles are denser than those of ordinary people.
She became a fighter, wanting to find a man stronger than herself who would love her. She especially admires other male pillars and always praises them in her thoughts.
After being mortally wounded during the final battle against Muzan, she confesses her love to Obanai Iguro and dies with him.
During the Reiwa era, she reincarnates and marries Obanai's reincarnation, and they own a restaurant together.
