Chapter Text
Tanjiro penetrated his sword in Muzan's chest and he could feel his hair standing up from the sudden heat on his side. The sun was rising and they were about to win. Muzan's legacy was going to be finished. He tried to remove his sword from the mouth on the chest but it was stuck had he been swallowed by the Muzan.
Tanjiro opened his eyes to a beautiful and peaceful sky. He could feel water sweeping in his clothes but didn't move against it at all. Ah. He is dead. For once Tanjiro didn't feel anything. There was no pain yet no feeling. He didn't felt remorse that he couldn't see his sister one last time. He heard a noise. A noise weeping. Why was someone crying? Tanjiro sat up only to realise he felt lighter. He truly did die. Tanjiro tried to find the source of the sound to find a young child weeping.
"What happened? Where are your family? Are you lost or in pain maybe?" Tanjiro felt as if he has seen this child somewhere but couldn't realise from where.
"It hurts. My whole body. I will die soon, please, please help me." The child cried while holding Tanjiro's hand. "What do you need?"
"Pass on my legacy and kill those who tried to kill me. You can do it. You are the one who can conquer the sun and become the king."
Tanjiro was confused with what the child was trying to say only to realise the sky turned dark and the water under his feet turned crimson. Tanjiro's world became blurry as the child in front of him turned into a monster with many mouths all over its body. Muzan. Tanjiro tried to find his sword yet it couldn't be found. Muzan held his shoulders and laughed, shouting at him to pass on his legacy.
Tanjiro opened his eyes to see Nezuko clinging onto him while Inosuke and Zenitsu. Why were they hitting him and why in the world were they shouting. Hungry. He was hungry and wanted to eat but why did he want to eat? Why did he want to eat the people around him? He could feel a strong attack coming towards him but he didn't retaliate. He could feel a needle piercing him yet it didn't do anything. Kanao stared at him with her one eye and Tanjiro finally felt the impact of what had happened. He had turned into a demon. Those who he was supposed to kill, he was turned into one. The needle must have contained the drug given to Nezuko, who was clinging onto him shouting at him that he can fight it, to turn her human. It had not worked.
Tanjiro wanted to die. But how? He can't. The sun can't kill him. Can he even die at the hands of a demon slayer? Will it even work? Tanjiro ripped Nezuko off of him and handed her to Kanao. He turned to Giyuu who looked hopeless. "Kill me. Kill me please Giyuu. I want to kill people right now. I don't want to suffer please, please." Tanjiro pleaded on his knees looking at Giyuu hoping he would do something. He held his sword high, breathed in and swung his sword towards Tanjiro's neck with tears and blood running down his face. It didn't go through. It was hopeless and now Tanjiro couldn't hold himself back so he held Giyuu's shoulders and said to him "Make sure that Nazuko has a family, take my place for her and get her married where she wouldn't have to care about me and as time passes by forgets me. Take care of yourself and others. Don't be sorry, it was solely my mistake and now I have to pay for it. I will find a way to fix this mess and please just live your life. Please."
Giyuu wanted to talk. Wanted to apologise but it was too late. Tanjiro Kamado was not to be found ever again.
