When the night began, Kokushibo didn't expect for the next night to start with him having a young human boy under his care... Oh well, you can never be so sure when life decides to throw something unexpected at you. (Or: Tanjirou gets orphaned and left in a forest. Luckily for him, someone takes him under their wing.) [Kokudad and Tanjison fr fr they so wholesome]

Muzan Kibutsuji, the demon king, the demon lord, the ruler of all demons. He is known for his ruthless behavior. No one can escape his eyes or his power. To him, humans are only a source of food. So what happens when he unexpectedly, by his own free will, adopts a human boy? A son of the Sun breathers even.

muzan visits earlier then expected for the kamados and ended up with a child to raise

What if Muzan found out that the Kamado family were the descendants of Yoriichi Tsugikuni, the first breath, and went to destroy them, but ended up not killing Tanjiro and raising him to make him a spy for him? Beware of manga spoilers!! 🚨 ~~~~~~~ This is a personal fanfic, there's a lot of fanfics that are like mine, so don't be surprised if you read something like that. And I DO NOT OWN any of the characters nor the original story. #1 swordfighting 2022/02/01 #1 demonslayercorps 2022/08/02 #1 douma 2022/08/19 #1 blooddemonart 2022/09/25 #5 powers 2022/12/07 #2 demonhunter 2023/02/22

Kokushibo envied his brother. He envied Yoriichi until the day the man died of old age. He envied and loathed Yoriichi Tsugikuni. After Yoriichi's death, Kokushibo's life was... better. He grew stronger, like he wanted to. He buried the memories of his brother in the depts of his mind. However, those memories are brought back up when he encounters a young Demon Slayer, who resembles Yoriichi too much. ------------ Tanjirou Kamado never expected to encounter Upper Moon 1 on his mission. And he also never expected for this to be his fate. Life is an unpredictable game, and he is only one of the players. (This is a rewrite of a crappy old book which I have now deleted. This idea was inspired by this fanfic on Ao3: https://archiveofourown.org/works/47640022 PLEASE go read it)
