At the Uyabishiki estate, during the aftermath of the Sunset Arc, the remaining Hashira are gathered, along with the remaining Kamaboko squad...meanwhile, back at the battlefield, Giyuu is on his knees, with a few helpers and a uniform maker near tanjiro battered, bloody, poison ridden body. His left arm's gone, and Muzan's demonic poison has taken over my right eye...he was unresponsive...Tanjiro hold his broken nichirin katana in tanjiro right hand, with the blade in Tanjiro lap...there is no sign of a pulse from him... as Giyuu sat there,Giyu sat beside Tanjiro motionless body, holding his katana. He was trying to keep himself together, but he soon started tearing up. All the Hashiras, and the remaining Kamaboko squad members sat nearby, hoping that he make it out alive.

"I failed protect someone again..."

looking at tanjiro's lifeless body His heart wasn't beating, but no one knew he was going to turn into a demon Muzan was dead but he gave Tanjiro a lot of blood and burned to death, some of it still inside him. Sabito his best friend dead and his sister died now he lost Tanjiro he considered friend Giyu has nothing to lose.Sanemi was sitting there as well, he felt the same way, he felt that Tanjiro was going to wake up. But deep down he knew it wasn't the case, Tanjiro had no heartbeat or pulse, Tanjiro was in no condition to wake up. Sanemi knew that deep within him.Because a part of Muzan lived in him. Muzan's plan from the beginning was to turn Tanjiro into a demon because tanjiro killed kamado's entire family but didn't kill him except nezuko he made him a demon and nezuko kamado tanjiro's sister was immune to the sun and she could resist his hunger for human flesh. That's why he injected Tanjiro with a large amount of blood before he burning in the sun.
