Tale of Dark Gathering (Undertale x Dark Gathering Crossover Story)

Chapter 1 - When Skulls Collide

(Back at Yayoi's world, the world that is filled with ghosts. Yayoi and the others semmed to be overwhelmed by the aura surrounding that black hole as powerful winds blow away both Keitaro and Eiko out of the way, separating the group.)

Keitaro & Eiko: Yayoi!

Yayoi: Keitaro! Eiko! Whatever is in that black hole...It must be very powerful to be able to knock back so easily, and very far too.

(Yayoi brings out a crowbar)

Yayoi: Well, I can't take any chances. I must rid of this thing from existence immediately. I may not be prepared but I must destroy it before it causes harm to anyone else. Whatever it takes, I'm gonna get the job done.

(Yayoi rushes in and gets closer to the black hole. Soon later, Sans appears out of the black hole)

Sans: Huh? Where am I?

(Sans looks at his surroundings)

Sans: Cars...Crystal clear waters...Bright blue sky and bright yellow light...This must be the surface. But how in the world did I end up here?

Yayoi: Hey, you...

Sans: ?

Yayoi: So you must be the one responsible for that huge mess in the sky. *points to the black hole* I saw you come out of that black hole there. Well, I didn't expect a ghost to look exactly like a skeleton but it doesn't really matter any way. I'm taking you out.

Sans: No, I was literally brought here against my will. And what's this ghost stuff you're spewing at me?

Yayoi: Don't try to fool me, ghost. I can tell right away that you've got something to do with this black hole in the sky.

(Yayoi's skull eyes glows red)

Sans: Like I said I didn't-

(Yayoi suddenly attacks Sans with the crow bar but Sans quickly reacts to the attack and dodges it.)

Sans: Woah! What's your deal kid?

Yayoi: A ghost that dodges? Well that's the first I've seen of this. You must be afraid of me then. For a ghost that surpasses an S-Rank danger level, you seem pretty weak.

(Yayoi repeated strikes Sans with the crow bar as Sans keeps repeatedly dodging them left and right.)

Yayoi: You're good at dodging. But that won't do any good against me.

Sans: ?

(Yayoi prepares a sneak attack behind Sans. However...Sans uses his gravity manipulation/telekinesis powers to hold Yayoi in the air and choking her.)

Sans: Alright kid...I didn't want to have to do this but...You've forced my hand.

(Sans summons his gaster blaster)

Writers Note: For those who don't know or need a reminder, a gaster blaster is a skull-like dog that shoots lasers out of its mouth.

(Sans then uses the gaster blaster to blast down Yayoi. Meanwhile...Nightmare and Kami watch the battle that is occurring right now.)

Nightmare: Good...All according to plan.

Kami: I must say...This is a good idea. Using that skeleton that looks like you to take down my enemies. But I have to ask...What made you think of this idea?

Nightmare: Well, you remember our deal right? "If you help me achieve my goal of conquering the Multiverse, I'll give you the thing you desire the most." And by forcing these two to fight to the death, I'll get the negative energy I need to conquer this Multiverse, and we'll both get what we want.
