Kyoujurou Rengoku ( (れん) (ごく) (きょう) 寿 (じゅ) (ろう) Shi no kata: Uchishio?) was a Demon Hunter and the Flame Pillar of the Demon Killing Corps.[1]


Kyoujurou was a young adult of tall stature with bright yellow hair with red streaks, black forked eyebrows, and golden eyes.

His outfit consisted of the regular Demon Hunter uniform along with a white-yellow gradient pattern and red flame-like ridges at the end.


Kyoujurou was greatly enthusiastic in regard to his duties as a Pillar and often cheerfully eccentric. He was amiable, kind 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 that those who were born strong have a duty to protect the weak.



Natagumo Mountain ArcEdit

Kyoujurou was present with his fellow Pillars when Kamado Tanjirou awoke.[2]

Functional Recovery Training ArcEdit

Kochou Shinobu noted that Tanjirou was on trial, which Kyoujurou saw no need for, as the youth's protecting of a Demon was a clear violation of conduct, a matter he stated they could deal with themselves. He then agreed with Himejima Gyoumei's idea to kill Kamado Nezuko, witnessing shortly afterward Tanjirou's coughing fit, and remained silent when Kanroji Mitsuri asked if they should be dealing with their subordinate's trial without Oyakata-sama's input. After Tanjirou headbutted Shinazugawa Sanemi, Kyoujurou looked at Mitsuri when she laughed with a neutral expression.[3]

Demon Train ArcEdit
