Tanjiro was walking around swordsmith village looking for muichiro with Zenitsu, along being guided by a kakushi. Then Tanjiro hears a familiar voice call out to him. It was Valerie, who was running to him in her robe she usually wears after she goes to the Hot springs. Tanjiro immediately runs to her as he yells

"SIS–SLOW DOWN–! YOUR BREASTS ARE THIS CLOSE TO SPILLING OUT!"

He grabs her robe and pulls it forward to cover her chest. Zenitsu is in the background as red as a tomato.
