It's been 5 years after the Tenma War and Rimuru could be seen doing paperwork. Yes it skipped because everything went in Canon and the MC really did followed that route
A portal appeared on the office where Rimuru was doing paperwork and yes he was doing a bunch of them
A person wearing a maid outfit came out and saw Rimuru and Rimuru stared at the person and said
"Hello Mizari is there a meeting again?" Rimuru asked politely
"Yes Rimuru-sama I apologise for disturbing you with even though you had so much work" Mizari said
"Don't worry already done and I'm actually bored... so I assumed that everyone was on the meeting?" Rimuru was now beside Mizari as he asked the maid
"Yes"
Rimuru then patted her on the head and pushed her gently and she now entered the portal and after a few moments he entered the portal
-_-_-_-_-_-
Mizari was stunned and was slowly blushing but luckily and unluckily she was snapped out of it by her fellow maid Raine
"Mizari! Mizari! where's Rimuru-sama!" Raine asked excitedly and everyone in the room couldn't help but smile at her because they knew about the Rimuruism and actually some Demon Lord's were part of it
At that time Rimuru appeared and he was smiling as always but he was thinking something
'This is the third time this week... oh well let's see what's up and if this is pointless I'm leaving this world and travel to wherever I want' Rimuru thought
"Heya!" Rimuru greeted everyone as he sat down to his seat and he then noticed that his subordinates and some people was here like all the three true dragons and more
"Good that we are all here... we decided to... blah blah blah blah blah blah" Leon started to explain what they were there for and Rimuru's eye twitch
-_-_-_-_-_-
"Sensei are you alright?" Chloe asked Rimuru
"Yeah I'm fine..." Rimuru then slam his hand on the table gaining everyone's attention
"3...2..." Veldora started to count with a grin on his face
"1..."
"Veldora you know where I am going and again don't tell anyone!" Rimuru said while standing up and walking towards the exit portal
"Use protection!" Veldora shouted and burst out laughing when he saw Rimuru tripped into nothing
"Just kidding go on just don't overdo it this time" Veldora said with a serious face and voice which was very rare for him
After Rimuru left everyone turned their head to Veldora wanted to get some answers
"Hey lizard what the hell do you mean don't overdo it this time" Ruminas asked
"Tch..." Veldora became annoyed all of a sudden and this surprised everyone
"Veldora what is going on" this time Velgrynd asked
"sigh... I couldn't be angry after all you all didn't know about this but... question... do any of you knew about Undertale?" Veldora asked
"Ahh! that popular game!" Masayuki said with a face of nostalgia
"What's that?" Velzard asked
"Well it's a game where you would play as the Human who fell from the surface and now you we're stuck to the underground full of monsters" Masayuki explained
"A video game?" Hinata questioned and Masayuki nodded and explain what video games was and everyone understood it
"In that game you could do Pacifist, Neutral, and Genocide route. Pacifist was the ending where you escaped the underground with the Monsters and they became your friends or family if you saw them as one"
"Neutral is like if a monster tried to kill you, you killed them to survive but if they didn't you could spare them"
"The Genocide was you kill every single monsters on the underground and leave the underground and you will going to have a choice if you wanted to destroy the world or not" Masayuki explained
"That's interesting so who's the strongest?" Guy asked
"Sans" Veldora proudly said
"I fully agree he made me rage quit the game many times and I only beat him once and I still remember It took me 55 tries just to beat him once!" Masayuki said with a depressed voice
"And he only has 1 ATK" he added
"What's that?" Raine asked
"The amount of damage you could do to your opponent" Masayuki said
"HP is your life points you ran out of it you died... MP is your Magic points... DEF or Defense if how much you could take without affecting your HP I guess... and ATK or Attack... you knew that already" Masayuki explained
"So... what are his Stats" Hinata asked
"1 HP, 1 DEF, 1 ATK, MP I don't know how much MP he has" Masayuki said which shocked everyone
"He was very weak then how could you lose to him!?" Chloe asked
"He was always dodging and his Attack pattern was so hard! and if you spare him he would just kill you!"
"Wow... that's something so why did you mentioned that Veldora-san?" Shizue asked the Storm Dragon
"Well... Oh shi-" Veldora then caught something heading towards him with a great speed and when it stopped and he looked at it he sighed and lay it down to the floor
Everyone was in shock
"What!?"
