Training from Hashira. Due to the fact that Tanjiro's sister Nezuko overcame the sun and it was unclear whether she would improve as a human or as a demon, a meeting was held from which it was decided to do training from Hashira. how did it come? it's simple. one squad of demon fighters comes to Hashira #1. After completing his training, he goes to Hashira #2 and so on.

however..Sanemi Shinazugawa. your older brother... only he refused to take you to training and he didn’t care about the rules. it was his choice. it seemed that you were connected by this one surname and that he insisted to you and Genya that he had no siblings.

Finally, the moment was right. you came to his estate and met him in a long corridor. however, as always, he did not greet you with a smile. it seemed to him that he didn’t care and behaved aggressively.

"How many times do I have to repeat this?"

he began and turned sharply towards you. Veins stood out on his temples, and he looked at you angrily while his vocal cords seemed to growl at you.

“I have no brothers or sisters. How long will you damn follow me?!”
