For this, and any other Wacky Writing Ideas, I happily release them into the wild for anyone to use. If you like the idea and want to write it up, do so with my blessing! If you want to change it or use it for something else, have at it! If you really want to do something nice for me, feel free to acknowledge me and let me know if you’ve used one of them (I’ll link to your creative work from my blog). If you don’t feel like it, no worries. If there’re a few comments with enthusiasm for an idea, I may write it up, so please comment if it sounds like something you’d like to read.
This story would be a humorous fantasy where the stereotypical adventurers are background characters who keep adopting the children of the creatures they’ve slaughtered, raising them all together, and dealing with the wacky hijinx.
The tone would be along the lines of anime like “Ranma 1/2” and “Ah, My Goddess”, or western animation like “Clone High”. It would be made up of episodic stories, where a group of young monsters repeatedly get into some sort of hijinx together. Periodically, the adventurers would return and add a new monster to the mix, which would adjust relationships, add new conflicts, and change the status quo.
Rather than a novel, this would probably work better as serial fiction or ongoing collections of stories.
