You, rengoku and the trio was having a fight with akaza, but rengoku was the only one fighting him since the trio was hurt and you were helping them, you all guys watch rengoku and akaza fight, until you guys saw something you guys never wish to see, akaza punches a hole in rengoku's stomach, making a big hole left, akaza pulled out of rengoku and let rengoku fall on his knees.

Tanjiro: RENGOKU!! he screams after him, while you, zenitsu and inouske was looking at rengoku and akaza.
