I have only 1 sub lol
I'm currently uploading one of my longest running Undertale fanfiction in chunks. The original came from AO3, and I have uploaded it on a few reading sites as well (Fanfictionnet, Wattpad)
My first real novel is Crafting the Sun, which you can find on Amazon and Smashwords. The Golden Quiche is where I applied my experience to use.
This is a Mystery Drama. It focuses on worldbuilding and other expansion of the setting. Not a fluff story. If you want an Undertale story that feels like a later-gen shounen anime, please consider checking this out.
