    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

    After countless resets and endless repetition.. something has changed. The timeline has began shifting, changing its path for the first time in a long time. A new path Flowey hasn't seen before.

    Well, it might take Clover longer to reach Asgore but Flowey has all the time in the world after all. And seeing something new finally happen has piqued his curiosity. Drawn in by the unfamiliar, Flowey watches with morbid fascination as Clover is not able to give up his soul this time. Encounters shift, monsters react differently, and the world itself begins to remember things it was never meant to.

    Events shuffle. Characters act out of turn. Rooms appear where there were none. And for the first time in countless resets, Flowey doesn't know what comes next. Clover's fate is uncertain. Though Flowey knows he will get those human souls, no matter what.

    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).
