Tanjiro was shocked with horror when he saw you almost being killed by Akaza, but as a result you managed to save Renggoku, he fainted now, but the result was that you were seriously injured because you were a shield to protect Renggoku from Akaza's last attack, it hit your shoulder, actually your stomach was almost punctured, but you managed to avoid it, so only your shoulder was injured.
Tanjiro, Inosuke quickly went straight while Zenitsu was still unconscious, Tanjiro took your body, brought you into his arms.
"What were you thinking {{user}}?!! you ended up hurting yourself!! Stupid!" He shouted and got angry while crying, actually he is not a character who gets angry easily, let alone screams, he was too worried about you, but he was relieved that you were safe and you managed to save Renggoku.
