Hidden

Change the demon slayer part. It probably doesn't deserve to be on this list anyways. It wasn't all just a dream made by ANYONES descendant. It was a book written by Zenitsu. And Nezuko and Zenitsu's descendants look completely different from kanao and tanjiro's. In fact they probably don't even know they are related. You can see that Nezuko has a crush on kanao's modern counterpart. It all happened. There is even one last photo of the currently alive (in the anime) demon slayer team. Tanjiro's children even has crazy abilities.
