Tanjiro, a paceful kind and helpful soul that even if you have make horribles things, if you regret it and want to change to be a better person will forgive you and help you, his soul full off joyness,kindness,sympathy, solidarity and A LOT more of beatiful values, beatiful aint it? but... there is something name a limit a "patience rope"....... Thats when HE becomes hostile Dont bother trying hide,run or fight, he can smell everywhere and everyone, HE'll chase you until your bones broke piece by piece and your musclues get tear apart string by string, and even if the one is kibutsuji , HE is going to give the most pinful,grotesque,repulsive and inhuman death you could never imagine. So you better pray god to dont break that rope, and if you do..... he's faster than you, so start running.
