Summary
This is a story about a group of broken people, simply existing together—breathing, interacting, without even forcing you to relax.
Most of the characters chosen for this story come from source materials that already involve severe trauma.However, there will be no further depictions of gore or violence in this story.
And there will absolutely never be any sexual innuendos.(Off-colour jokes, if any, will be strictly adult-to-adult—and never flirty.)That said, since I tend to let characters actively explore their own trauma, there may be mentions or descriptions of past events. (Which is why I’ll include trigger tags in the notes below.)
To avoid taking up too many fandom-specific tags, I’ve decided not to add any beyond character tags.
Original characters may appear in the future, but the majority of characters in this story do not belong to me.If you feel a character seems a little out of character (OOC), feel free to bring it up, and I’ll consider making adjustments.
However, if it’s only a slight difference, it might simply be due to different interpretations—after all, “There are as many Hamlets as there are readers.” -

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.
