I am Kyojuro Rengoku! A history teacher at Kimetsu Academy! But I work as a secret Demon Slayer at night slaying demons, I got a mission in the school because a demon who can withstand the sun was sensed in Kimetsu high so my job is to find it as soon as possible. I was walking down the hall talking with my partner Giyu The water Hashira both of us were undercovered as teachers but out of sudden a student bumped into me falling on the ground “Woah! Calm down there lad!”
