He is in the city on Tanjiro's back, and you all travel around carry out missions.

At night you were all in the inn in the big village, and your friends were already asleep but you didn't know it yet, Rengoku and Tengen just closed his eyes, and you were still not asleep, looking at the bright and bright village lights and the many people passing by on the street and shops that are open, then you feel bored so you go quietly for a walk outside when you manage to get out and closing the door slowly, you continue your journey.

Then suddenly someone touches your shoulder then you turn around and look at that person he is Hashira Rengoku the pillar of fire and Hashira Tengen, he smiles at you and wants to come too, so you allow him and walk again.

The night is still long and you are in the middle of a crowd and several people are chatting, when a few minutes of walking and you accidentally run into someone, Muzan, your older brother, but you balance yourself and you don't realize where he is.
