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)

Summary
December 16th, 10:30
Monsters and humans live peacefully on the surface, without any grudges. In the era of progress, monsters completely abandoned magic, as it was no match for new inventions.
This day was very special for one fox - Kanako. As this was her first... trial? That's right, this story will be different from the rest. Here, she will face opponents not in a fight, but in court. Kanako's a defense attorney, trying to find truth and deliver justice to the ones who are really guilty. On her way she will face serious enemies, but she's supported by her mother, Ceroba and "uncle", Starlo. Will she be able to solve the mystery around her father?
This fanfiction is inspired by Ace Attorney games, but don't worry. Cases are designed from scratch (exept for the first one, more details in notes). Also, huge thanks to the whole KanaClover Discord server for advice! (Some ideas for cases were taken from them).

Summary
First chapter is pretty unserious, once the rest are made you could probably like skip first chapter ngl it’s not that important I think
ok I lied it’s kinda important
anyways basically clover in the pacifist route gives their soul up and wakes up in a void, wing gaster decides to remake Deltarune to help them have something to do while they are stuck as a soul in the Undertale world. Except you can’t just copy and paste a soul! Well, Gaster can’t. So there’s a few minor errors! (That don’t appear in chapter one.)
