After that.

"I'm so tired I need to eat something" as Nightmare was passing by he saw Shin was talking to a girl.

"Huh who is that girl don't tell me Shin has a girlfriend what's her name?" Nightmare slide to peak by.

"So I was wondering if we could study together later you know about occult" said the girl.

"Oka I know your interesting about Occult but listen currently I'm leaving the Occult club and I also say that you should also leave the occult club either" said Shin.

"Actually I came here to say that too" said Oka.

"Really that's great well what are you gonna do now maybe later lets get something to drink" said Shin.

"Yeah that's great" said Oka.

"(Hmmmmm so he really does have a girlfriend)" Nightmare just looks away and sat down doing nothing an thinks for a while.

"(Should I even be bad or good)" Nightmare was suddenly cut off by Killer.

"Hey Nightmare I think it's right to eliminate that yandere she's reminding me of my past self before I was changed by Sans" said Killer.

"Really, What is happening?" said Nightmare.

"When I was walking by the classroom I notice that the yandere is talking to a black and scary figure in the Occult room I think she's making deals with the devils" said Killer.

"Alright thanks allot, think again I think your free to go, go back to the pacifist timeline with Sans" as Killer wave his hands and Nightmare drowns him back to Ebott City.

"Hey there Killer seems like your having nightmare issues again" said Sans.

"Heh no worries Nightmare's gonna changed" said Killer.

As the 2 all walks back home.

Back at the yandere universe.

"Hmmm" Nightmare peaks thru.

"So I have a question and here's a sacrifice for that" said Ayano.

"Alright ask quickly humans are not allowed to see me except the ones that makes deeds with me" said the devil.

"Well you see here are you familiar with a devil named Nightmare?" ask Ayano

"No infact I've never heard of an demon that comes from hell named Nightmare before" said the devil.

"Wait then who's talking to Shin that time was it all just a prank" said Ayano.

"Wrong Nightmare is the guardian of the negativity and darkness he might as well resemblance to a demon but he's actually just a monster that accidentally became a bit freaky during an incident that happens in his world" said the devil.

"Then how calm Shin was been able to communicate with Nightmare?" said Ayano.

"Oh it was because God brought Nightmare to this world so that he could help Shin" said Devil.

"What? Help with what exactly?" said Ayano.

"Help from solving your murderous crimes Ayano, Shin and Nightmare has found out your true identities along with Info-Chan's although too bad for Nightmare since Info Chan never reveals her true name so there's no way to know what is her real name" said the devil.

"WHAT BUT HE SAID HE NEEDS NIGHTMARE TO HELP HIM CRACKED A VIDEO GAME THAT I don't know it actually existed" Ayano quickly pulls out her phone and search for a game named Undertale but there were no results of it only randomized pictures.

"I think Shin and Nightmare must have knew you were on to them also, so they fake that they are beating a game that actually doesn't even existed so that you'll become less suspicious in them" said the devil.

"What should I do? What is Nightmare's true weakness?" said Ayano.

"There is no way you could succeed when Nightmare is still here his powers are stronger than mines and all of the other demons that you could make deals with" said Devil.

"WHAT AT LEAST GIVE ME AN UPPER HAND SOLUTION" said Ayano.

"*Sigh* Nightmare could detects the peoples that has the largest sense of negativity, your sense of negativity is increasing even more when your murdering the students which leads to the point he could sense you even if he's from a far away nation" said the devil.

"WAIT you mean I must increase my sense of positive" said Ayano.

"Listen if you increase the sense of positive you'll attract another version of him I could be sensing now it's Dream the opposite version of Nightmare used him as an alliance while you hide away your true identity" said the Devil.

Nightmare passed by to another side of the school thru the walls directly to the city and tries to find and think where Dream could be.

"Come on where are you Dream at least come here and give me a hand" Nightmare thinks and thinks when suddenly he notice a thing.

"Great must feel positive what does make me feels positive huh" Nightmare remembers his memories with Shin.

"Shin was the only person who understands me heheh thanks to him I was been able to have hopes again heheheheahah he even started to become better instead of focusing on demons he's ready to face the reality of the world along with his girlfriend hahaAHAHAHAHAHAH I'm proud of him" as Nightmare starts to remember all the good memories about him and his brother and attracts his brother Dream.

"Huh there's an strong and sadly positive emotion it's fading away" said Dream as he looks through and notice it's from an AU.

"I better go and check on him" said Dream as he teleports to see the person that is having this emotions and what he saw was.

"*GASP* Nightmare oh no" as Nightmare turns around and saw.

"There you are" said Nightmare.

"WHAT DO YOU WANT?" shouted Dream in anger.

"I need your help of rescuing thousands of lives in the school" said Nightmare.

"What?!" after Nightmare's explanation.

"I see so you've changed" said Dream.

"Yeah so are you gonna help me or not" said Nightmare.

"Sure thing brother" said Dream is happy.
