Fantasy How To Summon a Friend (found family)

[Just Peachy]

What started as a joke turned into something I would be down to do, a little 7-year-old boy who is so lonely he decides to steal his father's demon summoning book and summon denim to be his brother/friend to build forts with since his dad refuses to.

This is a little found family roleplay I've been thinking about doing for a while ever since I and my friend made sketches about the idea and I thought it would be an ADORABLE little roleplay! I was thinking of a slow burn where the demon acts all distant but has to do it since it's their job (like a contract demon, we made a joke about the boy being too young to sign it so he has to sign it in his father's name) though eventually, the two grow closer then bark on a tree and the demon decides to take the little one away from his abusive household and I have a couple prompts for a setting too!
​

• human beings are not welcomed anywhere else (they're seen as disgusting useless beings since they can't use magic and just make conflict) when they eventually do leave since it could be like a fantasy setting with elves and succubuses and hell being a realm witches visit and etc​
• It's a post apocalyptic landscape where nowhere is safe for raising a kid since demons have taken over the fantasy realm​

If you have any other ideas or don't like the two prompts we can brainstorm one ourselves or we can combine the two if you can't decide :>
Please DM me if you're interested or for more info ​
