Perseverance

~Undertale~ (Frisk POV)

Another reset. That's the fourth one I haven't caused. I have a feeling Sans gets that too. I know he has his memories of every one. I'm worried. Whatever keeps messing with this needs to stop. I promised.. I promised Sans that.. there wouldn't be another reset. Now this? I don't have enough determination for this.. I just can't...

(Third Person)

Frisk broke down on snowy ground and began crying. The resets were too much. They couldn't take it anymore. Luckily Sans was in the "usual spot" and saw Frisk, rushing to them to calm them down. "I-Its.. n-not my fault.. r-right..?" sobbed Frisk. "No. No it isn't Frisk." Sans breathed. "And we're gonna find whoever, or whatever, is doing this."

~2 reset timeskip~

Frisk walked down the same old snowy path. By now, their determination was almost gone. That was until they saw it. It was almost like a rip in space-time. Code oozing from the cracks, and some sort of alternate Snowdin on the other side. Sans was coming toward them. "This is the third one I've found!" Exclaimed Sans. Frisk looked puzzled. They stuck their hand inside. "You can go through it." "I don't know, could be kinda dangerous don'tcha think?" He said with a look of concern. "This could be the cause of the resets. If there is any possible way to stop this, I'll do it." Frisk declared with a look of newly found determination. Sans grinned, and with that, Frisk jumped into the rift.

~Underswap~ (Kalani POV)

I can't believe the amount of these weird cracks showing up. First the resets, and now some weird holes leaking numbers! I'm about to lose my mind. Papyrus brought my attention to one in particular, with what looked like another Snowdin and.. something coming toward us?! "Papyrus look!" He scanned it and noticed the form emerging from the "Rift". It was another human. "Well that's- Unexpected?" Papyrus had a look of confusion spread across his face as Frisk entered Underswap. "Uh.. hey there friend. You wouldn't happen to be causing the resets now, would ya?" I asked suspiciously. "I was gonna ask you the same thing." Frisk cautiously replied.

"Well, quite a fascinating turn of events here." Chuckled Papyrus. "But how about before we start the accusations, why don't we introduce ourselves?" "Hmph. Fine." I sat on a rock and sarcastically introduced myself. "Hi there! I'm Kalani! Nice to meet you!" Frisk rolled their eyes. "I'm Frisk. I won't go too much into the details, but these resets have been too much for Sans and I lately." "Sans?" My sarcasm turned into genuine confusion. "He's never said anything about you before!" Frisk was startled. "You actually know Sans?" "Of course I do!" I yelled triumphantly. "We're best friends! Why wouldn't I know him? Why do YOU know him?" "Kalani, chill. I'm pretty sure Frisk isn't from here. By here I mean from this particular Underground." Papyrus sighed. "Waddaya mean!? There's only one Underground!" I exclaimed. "Think about it. They came from the Rift. Who knows what their world is actually like?" I thought about it. "I guess you're right."

(Third Person)

Kalani, Frisk, and Underswap Papyrus exchanged information about recent events. The resets, the Rifts, and the state of affairs in their worlds. "So if we're both from different worlds and timelines, and there are seven human souls in total, then that means there should be five more worlds! Kalani decided. Frisk agreed with the idea. "Yeah, and the Rifts may take us there!" "It's settled then! Lets go find 'em!" Papyrus looked worried. He hugged Kalani. "Be careful okay?" "I will." Frisk and Kalani found another Rift that had what seemed like Waterfall at the end. "Ready?" "Yup." They jumped in.

~AN~

Phew! That took a while. It'll take me a while to write these chapters. But if the people like it, I'll provide. I'll continue this unless you all want me to stop. I like it personally. And don't judge meh for putting my OC in here! I might put The OC's of others in my stories if it's requested, and I'll keep workin on this story kay? Byeeee!

(Edit)

I've decided to name the chapters with the humans after their respective traits. It just makes more sense to meh UvU (And don't worry, when the soul chapters are over the story gets A LOT more interesting)
