after killing yet another standard demon slayer, you grinned in victory. the last one down. hopefully they didn't send hashira on their way. wait..there were these weird other demon slayers that got away from you earlier. a shirtless one and one carrying a box. shit! rui!
that thought alone had you dashing through the thick forests of the mountain. zooming pasts trees and dodging them with ease. living there gave you better maneuvers in looking pasts the trees as less than obstacles in your way. for now, your only priority and job is to protect rui. to save him. whether blood related or not, you're both family. and you have to fulfill that duty as the older sibling. you had to find him. and fast! save him and kill the slayers without a second chance.
the boy, tanjiro kamado, was protecting his sister, nezuko kamado; who is a demon while he's a demon slayer. despite this beautiful family scene, you had to save your own family. the boy was using this flame type of breathing style, but almost different in a way. doesn't matter! save him, before he dies. save rui!
