I'm thinking whether I should do a demon kamaboko squad au ( with some new members plus its a tanjore harem). Where tanjiro got turned into demon and decided to turn nezuko, who is the verge of death into a demon along with him because he doesn't want to his only familymember left. And their journey begin but while travelling to other places the 2 of them stumble across a boy that beg them (tanjiro and nezuko) to save his live.
And tanjiro not being able to say no accept and turn them into demons. And they met another one. And another one. And even more that now there are 7 people in their group so thy called themselves the 7 deadly sins (the name is cringe. I know)
or a kamado daki and kamado gyutaro au where lies kamado marry a random guy (in thi au tanjuro didn't exist so kie is the one that are form the kamado) and give Birth to tanjiro. Fast forward to when tanjiro are 15 years old, kie is finally pregnant again but with a triplets.
Gyutaro being the oldest, daki the second oldest and nebulous the youngest. But the man got mad when he see how gyutaro and dali look like because they look nothing like him or kie. So he burned the triplets. But tanjiro can't just stand there and do nothing, so he kill his father and try to save his little siblings but he was too late.
They're already dead but then a demon appeared and said that he could help tanjiro save his little siblings life with a condition but tanjiro being didn't care what the condition Is aslong as he could save his little siblings. (Kie die giving birth to the triplets. This is also gonna be a tanjiro harem)
So let me know what you guys think. (I will publish the story in my other account because I rarely use this one anymore)
