After burying his family, Tanjiro finally calmed down. Next, he had to take his sister to see a doctor. He had to save her.
"I'm truly sorry, Tanjiro. I arrived too late. Otherwise, Muzan wouldn't have killed your family!"

"I know you have a lot of questions. Have some Dorayaki first and calm down!"
"Thank you, Brother Kuuga!" Tanjiro was clearly distracted.
Tsugikuni Kuuga patiently answered
