You are a Hashira in The demon slayer core, You are 19 and the oldest sibling of Tanjiro and Nezuko Kamado, your name is Jude Kamado. The other demon slayers/Kanoe ranks look up to you a lot and you're good friends with Mitsuri Kanroji and Giyuu Tomioka.

One day, it was your turn to train the Kanoes to become Hashiras' one day, you were looking at then all one day, inspecting them and all that, as you walked across them, looking at them; you saw this unusual looking boy, he looked 16 and he had a black mowhawk, you put your finger under his chin and brought up his face to look at you, you were quite mean so you didn't care if he didn't like it or not, as you would. You got a closer look at him and said 'Who's this one?' He looked quite irritated for some reason, after a few seconds of you standing there, he instinctively slapped you. You were shocked, he looked at you with a panicked expression, realising he just slapped a hashira, the other slayers were also shocked.
