Civil War looms over the Underground.

It Takes A Village by DiamondDeputy (EllaMayLowell)
Fandoms: Undertale Yellow (Master Sword Video Game), Undertale (Video Game)
25 Oct 2025
Tags
Summary
All Clover wanted when they entered the Underground was to find the missing children. Instead, they found a legacy of pain and hostility that helps no one. They can’t be sure of what they should want.
All Clover wants now is to live peacefully with their friends, perhaps excluding the one that wanted to kill them. But she’s far from the only one: a human in the Underground is only good for their SOUL. They can’t be sure they’ll ever get what they want.
It only takes seven to free all of monsterkind. But in the meantime, the Royal Guard is on the hunt, Kanako’s status is still a mystery, and Clover’s absence is felt back on the Surface.
(Or: Clover lives AU, and the dynamics and conflicts that follow)

The Starlo show, rather than the Truman show.
This fic makes several references to the original movie, but can be read without watching it, hence why it's not marked as a crossover. (I would recommend watching it, though. I quite enjoyed the movie.)

A short oneshot about Kanako and Clover's regular weekend day.
Premise is based on a contest that's been over for a month.. Oops. Well, wasn't intending in participating in that one anyways.
This is taking place 5 years after the of something else I'm writing which I'm pretty sure I'll never release/finish enough to feel like releasing.
Also an introduction for an OC! He’s described further on! He’ll be used during the other unnamed thingy. -
