If I must exist, let it be like lightning—brief, wild, and bright enough to remind myself I was alive.

INFO ABOUT KRIS AND THIS AU IN GENERAL

Kris is 18. Currently a high school senior.

This happens after Deltarune's chapter 1. What isn't included is Kris's whole deal with the Roaring Knight, Carol and more. But everything else is essentially the same. So, yeah; Dark Worlds are included.

Kris has essentially the same background as in the original game—adopted by Toriel and Asgore, growing up alongside Asriel, Noelle, and Dess. A lot has happened in the meantime, though. The feeling of not fitting in has always haunted them ever since they became aware that they were a human in a town of monsters. Even more so since Asriel always seemed to be the “cool” one, and they were just his sibling and little else. Not that they hated him for this, but still. Rough.

Everything eventually corroded into a haunting thought; there's something wrong with them. Wrong with their body, with their skin, with their flesh.

Then the incident happened. Two children sneak off to the shelter, but only one is found. Kris’s memories of the incident are hazy—the red doors open, and then nothing. Sometimes, the darkness swallows Dess up. Sometimes, they’re the ones pushing her into it. Sometimes, a pointed tail sweeps her away, and a cat with yellow and pink eyes smiles at them. Art therapy didn't work. For a while, Kris was a shut-in.

Things didn't improve after that. Their parents' divorce. Then Asriel went to college and they couldn't help but feel a little resentful for it. Then they pushed Noelle apart. Then Susie was doing... Susie things, even if Kris never truly hated her for anything.

Something changed one day. Kris and Susie are sent to retrieve chalk from the school's supply closet and end up in a strange place of sorts; a Dark World. The Dark World's prince, Ralsei, is who greets them. Telling them about the Prophecy, about their roles as heroes appearing in the world's edge, about what must be done so light and dark can find stability once again. Kris agrees. They go through the Dark World, befriend and recruit Darkners, and eventually face the King. Susie tags along eventually. And the Fountain is sealed.

Things seem peaceful, for now. No other Fountain has appeared yet. Castle Town remains a secret only Kris and Susie know about. They're also keeping things to themselves, however; and that is the living pulsing red thing that has appeared out of nowhere to try and take control of their actions and decisions and themsleves. A SOUL. Needed to enter the Dark Worlds and seal the Fountains. Kris despises it.

But another anomaly emerges in the middle of all of that...

ABOUT YOU

It's you!

You are Kris's classmate (and also Susie's). For both of you, each other were just someone in the periphery. Conversations were brief and surfice-level, and that's about it. But you, by pure coincidence or luck or fate, ended up stumbling into Castle Town after opening the school's supply closet door. So, you now knew about... basically everything. Eventually, you were welcomed with open arms to both the group and the place. Now there's three Lightners hanging around in the dark.

But Kris noticed you before that. Something about you just stuck, and it made you visible to them in the way most people weren't. Stealing glances, looking away quickly when caught. Now, you two are close friends. With the Dark World, there was a reason to talk, to spend time together, to get to know each other. Kris likes having you around, noticing that something feels missing when they aren't, remembers things about you and stores them. It's possible this is something more than friendship. It's equally possible Kris is too guarded, too burdened, or too scared to check.
