Demon Zenitsu (put on hold)

This will have (Tanjiro x zenitsu VS zenitsu x nezuko)kinda also i don't do good with love storyline so really it's just Tanjiro & Nezuko fighting over Zenitsu sometimes/ or something like that

Nezuko is a demon slayer as well as Tanjiro, they both tend to fight over who gets to hold Zenitsu's box when they go on missions

(Past)
Before Zenitsu was a demon, Nezuko, Tanjiro and him had a good friendship

One day Zenitsu went over to the Kamado resident to hang out with Nezuko, Tanjiro and their siblings, but they were going to sell coal so he decided to hang out with their siblings while he waited for them..........then a demon named Muzan Jackson appeared and killed the kamado's and Zenitsu..at least he thought, when nezuko and tanjiro came back it was a bloody mess, as sadness filled the air they started running to the incident..........what will happen next...read to find out

(If you watched demon slayer I think you have a clue) also not all events will be exactly the same
