Summary
What if the player never existed?
What if instead of Kris, Noelle fell into that dark fountain with Susie?
What if Kris has no association with the Knight and knows nothing of the dark worlds?
What if the soul that was desperately needed to seal fountains was Kris's and Kris's alone, yet the human is blissfully unaware of how desperately they are needed? Of the leadership fated for them?
...
Kris watched as Noelle walked out of the classroom with Susie, sighing softly.
Whatever. Honestly...they knew they should care more but...Susie never bullied Noelle anyway....
However...for some reason after that, Noelle and Susie completely disappeared for the rest of the fucking day!?!?! And for some goddamn reason when they came back Noelle is randomly seeking them out and Susie is acting weird as fuck, and they're somehow a lot closer??? And for another unknown goddamn reason Susie WILLINGLY asked to do their project.
What the fuck is going on??????
Whatever. They don't need to be a part of this bullshit. At least Berdly is just as confused as to what the hell is going on with their project partners.

Cherry Sweet is a rather unconventional performer at a club like 'The Velvet Crop' with her thick thighs and plush stomach, but she does well enough for herself. The patrons enjoy a bit of variety, but what will she do when she attracts the attention of a monster--and a mob boss monster at that?
Featuring a 1920's vibe with music from the 20's-60's, a meet-not-so-cute developing into a partnership, and a spitfire, plus-sized FMC. I hope you all enjoy!

Let’s take a look at one of them to see how they live in such a world like this and find out for ourselves!
