Well sorry for taking so long. I tried to make it more longer and more interesting then the last one. So here it is hope ya enjoy.
Now that sans grillby and Chara are now in storyshift world. Error sans wants them to get rid of somebody entering the storyshift world and trying to start genocide all though there is two persons who will start genocide one from storyshift one from another au. As there story begins. There are at storyshift world as they walk out of undertale world the portal closes behind them leaving grillby worried. As he look back. And sans try to comfort him about it.
Sans: no worry bro we'll get back home.
Grillby: you sure?
Sans: how you think I got back home?
Grillby: okay...
Sans felt bad for grillby taking a risk on au traveling. Sans then worries if he gets lost. How will sans feel about himself if that happens. He cares less about Chara but grillby was his buddy sents they were kids while sans was in hard time. Grillby helped sans out in that time. So he really do care about him. Chara then look around left and right to make sure the area clear.
Chara: alright. It's clear
Sans: so two people we need to get rid of in this au
Grillby: I suppose that what error sans said
Sans: heh...you know it kinda feels like we're cops or something taking out people that need to be killed before they start a crime. Which sounds more like agents to me
Grillby: sounds like it to me
Chara: alright let me be honest I don't know where there at? *smiles*
Sans knew she had no idea where she at. But sans decided to take in charge and lead them. He feels like this place is simliar to his world.
Sans: alright follow me. I think I know the way out
Minutes later they went to the snowing forests and as they walk. One of them starting chatting while they were going.
Sans: so if asriel is your brother. Yet he seems to really like you. what dose that mean?
Chara: well he cute but he is my step brother. So
Sans: then?
Chara: look I don't love him. Plus he dead remember?
Sans: Chara the world reset remember? So everyone back alive.
Chara: I'm still with grillby
Grillby: she right about that
Sans: okay so if ya decided to have kids how well that work?
Grillby: what?
Chara: here it goes...
Sans: you know what I'm talking about
Chara: we didn't went that far. Maybe a little but not that much
Sans: wow
Chara: hehe
While sans and Chara were talking. Grillby start to think about that talk sans had with him months ago.
Flashback at grillby's
Sans: my mother was killed during the war of the humans. Ever sent then I always protected papyrus.
Flashback fades away
Grillby is still wondering if sans mom we'll come back alive after the reset. He still wonders if that can work. While still confused of how the world has this affect of resetting. Sans then look at grillby.
Sans: grillby? You been quiet the whole time. What going on?
Grillby: nothing...just thinking
Sans: grillby it's alright I know your scared. I was like that too
Chara: I wasn't scare I been through worst
Grillby: sans...
Sans: yes?
Grillby: nevermind
Sans: okay?
As they walk they seen they someone walk to them. There were two of them.
Sans stopped walking. Grillby and Chara saw them too they stopped as well. As sans made sure there not a treat. Sans was ready for a another fight
Sans: hold on. I see them
Grillby: who are they?
Sans: I'm not sure hang on...hey! What ya want!?
Chara: huh? Why dose that one look like...me?
Sans: huh?
Sans look at chara and the other person and turns out they are the same ones but with different clothing one wearing a lime green hoodie smalier to sans. And the other one is wearing a different clothing but had a rainbow colour like scarf. Same as papyrus he always wear a scarf but sans didn't put too much thought into that. As they walk towards them they revealed themselves.
Sans: who are you?
Storyshift Chara: why you look like the king for?
Sans: what? What king?
Storyshift Chara: why you wearing the same as im wearing?
Sans: why your so chill for?
Grillby: this may get awkward
Chara: why she looks so much like me?
Storyshift asriel: do they look like someone to you? Chara?
Chara: yes your looking at one
Sans: this is bold crap. Freaking error sent us here to be torment by clones of us?
Storyshift chara: error? What that?
Sans: Don't talk you stupid bumb.
Storyshift Chara: wooh. Chill dude
Sans: I ain't chilling at all! I'll be chilling hot when I burn you in hell
Storyshift Chara: well that a lame pun
Sans: my puns are gold!
Grillby: enough already.. look I apologise but my friends are very how should you say. Very upset of there new travel. Would you please tell us where snowdin at?
Storyshift asriel: sure I know where at! Follow me
Sans: alright you heard him let's go. I guess
So turns out sans didn't really like storyshift Chara for acting like him in a way. And starting to like Chara more then the new one he recently met. While they left to snowdin sans started to wonder this may be the worst travel so far. So as they went. They decided to go in storyshift Chara house and have coffee. To get a rest. While sans is more close close to his friends then them.
Sans: hey Chara...
Chara: yes?
Sans: I'm starting to like you now
Chara: me too
While the two were sitting in sofa. Grillby was looking out the window while he was thinking about how this new world we'll be now? As he thought of au traveling will be the best thing that ever happened to him. As his whole life was pretty much being a bartender. He never experienced this type of feeling. He felt real excited to meet someone else being a bartender on his role. While that storyshift asriel wanted to storyshift Chara With him and separated with the undertale group from them. While that sans take a map out of his pocket he forgot he had that sent he made it during his horrortale travel.
Sans: so I have a map I made in my last travel. So maybe we warn the king about what going on?
Chara: *looks at sans* why that?
Sans: to warn him about the dangers of what gonna happen in this au
Chara: oh that why. Well here one thing confusing me the most. Is that. Error sans is a au destroyer why don't he take care of them by himself? Why need us to do his dirty work?
Sans: *looks at Chara* you see that what talking about. He been acting very strange to me. Ever sent I got back home from that sick twisted horrortale world. He said if I don't work with him. All my friends and the entire au I live in will be destroy forever
Chara: sounds shady. So your Force to work with him?
Sans: yeah...what about you?
Chara: same thing
Sans: so we're both trap in this job
Chara: yeah. Ever thought of killing error sans off? Be worth it
Sans: as much is I do. But I don't know. I think he a god or something
Chara: more like the devil
Sans: exactly your not that bad you know. Your pretty cool
Chara: I know I am. How you think grillby dated me
Sans: I see. But...*looks at grillby seeing him looking at the window still and turn back to Chara and whisper* why you kiss me for?
Chara: oh that..well...you are cute too
Sans: I think you are
Chara: yeah but I'm with grillby you know that right?
Sans: yeah your right. Well hopefully grillby takes care of you
Chara: he will thanks *smiles at sans*
Sans: *smiles* you welcome kiddo
Chara: I'm eighteen
Sans: yeah alright let get to it
Chara: ready
All five of them left and walk to the kingdom as there walking. Sans know is that everything changed then his world. He then know is that he might bump into his other self. All though sans had a bad experience of his evil self in horrortale but then wonder if there still alive. Even Chara and sans both worried that error sans may not be the good guy they expected.
Snowdin
Horrortale
The world was on fire but horrortale sans was alive somehow and was very lucky he then got up and saw his brother dead. And realized the sans left with the others. He wanted revenge for what he did but saw a portal of blue light open up in the sky as he can hear error sans deep echo voice which sound it like god was talking to him from above.
Horrortale sans: what?...*growls of pain and anger* what the f* is that? Is that holy crap...is that...really god?
As he saw error land down in the ground he then seen how he was different then sans. He knew this was some type of alternative universe sans. As short for au. Error sans walk to horrortale sans and look at him. Seeing him suffer with anger.
Horrortale sans: please...help...me...he killed my brother and Chara that b* kill everyone started... genocide...please
Error sans: of course you can
Horrortale sans: you..sure?
Error sans: I need a army to fight back my enemy. She has the ability to draw anything and make it come to life. She is the creator. And I need an army to kill her off and all of her people. So I can take over every au and become god. I promise I can give you anything you want in life.
Horrortale sans: all I want is my world to be reset and my people...and...my brother...alive...and I want to kill sans and Chara!
Error sans: as you wish
Error sans reset the world of horrortale making everyone back to alive and restoring everything and everyone. Error also brought horrortale papyrus back alive and heal horrortale sans. As horrortale sans was so happy to see his brother alive.
Horrortale sans: thank you! What is your name?
Error sans: call me error...the destroyer
Horrortale sans: ...okay..
Error sans: what a matter?
Horrortale sans: nothing...sounds pretty evil for a god

Error sans: hold it..when the time comes then we'll attack
Horrortale sans: fine...
Back to undertale
Ruins
Papyrus was trying to find frisk and thought if she went back there. As he walk the entire worry about frisk. He then know is some one just got back to the ruins. A portal open up from horrortale and he saw error sans and horrortale sans walk out of the portal. Papyrus was shocked to see something like this. Frisk came around and hides papyrus with her. as the two see them open a portal to storyshift where sans Chara and grillby are at they both went in the portal leaving it open.
Papyrus: frisk where have you been? We supposed to be on a date you promise?
Frisk: papyrus. Look a portal.
Papyrus: frisk I didn't came all this way to travel portals with you
Frisk: pap I think there might be awesome date dinner for us in there.
Papyrus: well hell with it then let's go for it!
Frisk and papyrus went in the storyshift portal too. The thing is frisk was acting very mysterious of not telling papyrus what she been doing the entire week without being seen by sans or grillby. But papyrus will do anything to be with her.
Back to storyshift

Sans: so who the king?
Storyshift Chara: right there *points at storyshift sans*

Royal knight: as you wish my Lord *bring him a king size ketchup bottle to sans*

Storyshift sans: hey buddy we don't use harsh language in this world. Have matters
Storyshift Chara: I know that right
Chara: f* you *shoot the finger at her*
Storyshift sans: hey enough! There children here!
Chara pulls out her knife.
Chara: how about I kill everyone here right now. With you in it!
Storyshift sans: you dare threat the king's people! And me!
Sans: *sans right eye turns blue* wanna have a good time buddy. We can end this now...heh heh
Grillby runs and get in front of Chara and sans trying to back them away from the king
Grillby: will you two stop! Your acting immature. This is not what error wants us to do. Where supposed to help!
Sans: grillby get out of the way
Chara: honey will you move I'm trying to kill someone
Grillby: no this gonna stop now! I'm tired of you sans. Always complaining about your life. Always miserable and depressed. And you Chara your just crazy. You want to take fight out of everybody! Please just tell error to take ya two home I'll save this world for now.
Sans: grillby...your real hot head son of a..
Grillby: screw you sans! Your Nothing but a bumb! Rude ass bumb that all your ever gonna be just a bumb! The way you act and carry yourself your bumb sans! A bumb!
The rest of the kingdom got quiet after hearing grillby insult sans for the first time. Chara was real surprised he had that much to say to him like that. She never thought he had so much angered. For a very quiet calm guy to say all this. Sans felt real heartbroken after what he said to him. He lost all trust for grillby. Grillby pretty much choose someone else against his own best friend and his girlfriend.
Sans: grillby...wanna have a bad time! Because your gonna burn in hell...
Grillby: I already am with you all the damn time.
Grillby then glows and has fire ball coming out both of his hands and aims it at sans. And sans was just staring at him with a real angry impression on his face. While his hands turn blue fire.
Chara: grillby stop now!
Grillby: don't get involved! This is our fight!
Sans: it's okay Chara I got this heh...
Sans and grillby both run in the same time and both of them punch at the same leaving a big blue and orange explosion collided together as the smoke fade away sans and grillby stare for while. Letting there powers charge up.
Grillby: Don't make me do this sans! After all I done for you!
Sans: I gave you warning now I really mean it.
Grillby: alright you ask for it
Sans did a power no one has ever seen him do. He actually use a blue laser fire out of his right eye at grillby. For saving all his angry from horrortale and relasing it to grillby without caring. Grillby closed both of his fist and take his glasses down on his pocket and create a fire blast. As all of his fire from his body blasted out of him to sans stopping his laser from hurting him. As grillby fire was holding sans laser eye from getting closer. But then sans summon a gaster blaster and shoot another laser at grillby. Now two laser are hitting grillby at the same time. As so much pleasure grillby couldn't handle it blew him up and the lasers hit grillby causing him to fly back to wall and break through the stone wall of the king's castle. Causing grillby to have a headache and was in complete pain.
Chara: grillby!
She ran to grillby and Try to see if he okay.
Chara: your okay?
Grillby get his hand and aim it at her
Grillby: get the hell away...from me...
Grillby get up from the ground. While that 50 royal knights with swords and Shields came to protect grillby from sans and Chara. Even storyshift Chara and asriel came and protect grillby as well. As storyshift sans walk and his right eye glows blue.
Storyshift sans: get outta here! Or face the consequences! Grillby we'll be living in this world with us for now on!
Sans: find you can have his ass
Chara: look where both sorry about this
Storyshift chara pulls knife at Chara and asriel aim his black fire at sans. They both knew they messed up
Sans: let go Chara
Chara: I trusted you
Grillby: I trusted both of ya! But...you...we'll never see the last me.. I never want to see you again!
Sans: Chara let get outta here
Storyshift sans: if we see you again you we'll be sentence to death
Sans and Chara left the kingdom while grillby stay with them. Storyshift sans heals grillby.
Storyshift Asriel: your okay?
Grillby: I'm find thanks. And thank you king
Storyshift sans: no worrys
Grillby: but there still two more people who are about to start genocide in this very world we live in
Storyshift sans: maybe it's sans and Chara there the ones
Grillby: no there not
Storyshift sans: but they insuited you
Grillby: look we got to fix this before they destroy it
Storyshift sans: very well. Procced
Storyshift sans and grillby decide to head outside and protect the ruins. While sans and Chara find there way home. They both feel upset for losing there friend behind.
Sans: Chara what am I gonna do? What I'm gonna say when I get back home
Chara: I don't f*ing know!
Sans: chara...is this how you feel?
Chara: like what? This?
Sans: feeling like you lost your true friend the most?
Chara: yes..
Sans: me too...I'm starting to understand you more and more
Chara: it alright. It my fault
Sans: no it's my fault I brought him here.
Chara: yes but we both mess up
Sans: am I becoming like you now?
Chara: oh you get used to it. That why killing is a relief to me
Sans: I guess your right
Chara: sans *looks at sans*
Sans: what that buddy?
Chara: you can be my...um...
Sans: wait honey I know what your gonna say..but I don't think this is right
Chara: why not?
Sans: because it complicated...
Chara: not if someone understand you and save your life
Sans: your right
Sans then walk closed and put his hands on Chara hips and kiss Chara in the lips for the second time. As they have there moment. Error sans was watching and then walks by horrortale sans.
Error sans: well looks like it time for a change of plan. Chara and sans are in love and having there moments. I believe it's time to find the two genocide folks and hired them in my army. The war is coming soon. Sans and Chara do not know is what about to happen. Ink sans we'll never surive this war. My vengeance we'll be mines.
Horrortale sans: when well I kill sans?
Error sans: soon soon... But I believe I should leave you here. After all if you manage to kill sans and chara. It well make my job more easier. And maybe I can get grillby to work with us.
Horrortale sans: genuines idea. But what do I get out of? If I kill sans and Chara?
Error sans: anything you want
Horrortale sans: alright then I'll surprise you my Lord
Error sans: good you better
Horrortale sans: sure...
Error sans leaves the portal leaving horrortale sans to finally end sans and Chara once in for all. What well happen to grillby would he be working with error sans on his evil plot? Well sans and Chara ever forgive him? What would the people of storyshift well do about the genocide? Who are the 2 beings that are going to start genocide? Well horrortale sans end his revenge? Stay tuned...
