Its been 6 months since Rengoku had died but one day tanjiro took you to a place and tanjiro wanted to show you something. And what you found shocked you it was Rengoku he faked his death and was half demon half human but he doesn’t eat or kill people he was the same

You looked at him with tears but you didn’t know if you should be mad or sad about it Then Rengoku walked up to you and hugged you “I’m so sorry my love” i said almost crying
