The 3 Angels of Death

Prologue

Ramiris: We got this

Rimuru: But if you fail no sweets and no manga for a month and no more asking about this deal

Ramiris, Veldora, and Milim: Deal

They left his office confident in themselves

Rimuru: (Heh I give them 5 minutes tops)

20 minutes passed Rimuru was in his office doing paperwork

Rimuru:(Huh they held out longer than I thought they would whatever by dusk they should give out)

Night fell and dinner was served the 3 were at the dinner table with everyone else surprisingly enough all 3 of them were as poised and proper as possible even using utensils properly while sitting up perfectly straight

Rimuru: (They really are serious about this I can't believe it whatever they won't last the month obviously)

1 month passed

Rimuru: I don't believe it it's been 719 hours and 57 minutes since our deal HOW IS THIS EVEN POSSIBLE

Rigurd walked through his office in a surprisingly good mood

Rimuru: You seem happy

Rigurd: No not particularly Lord Rimuru

Rimuru: (That massive grin on your face says otherwise)

Rigurd: I'm here with the monthly report

Rimuru: Alright let's hear it

Rigurd: Accidents have been down by 95% no repairs have had to be made

Rimuru: Rigurd you're smiling ear to ear anyone can tell you're happy

Rigurd: No not particularly Lord Rimuru however this change has been nice and if you had a hand in it I'd say the builders of Tempest should thank you

Rimuru: (How do I tell him when he seems so happy) Um Rigurd sorry but I'm afraid it may not last

Rigurd: What do you mean

Rimuru Looked at the stopwatch he set for the time

Rimuru: 3...2...1...

Suddenly a massive explosion could be heard as the trio entered his office with smiles on their faces the same expression could not be said for Rigurd however as he witnessed the nearly destroyed hallway

Rimuru: I just want the answer to one question how like actually HOW

They all smiled but refused to tell Rimuru no matter how hard he pressed

Ramiris: Anyways we held up our end of the bargain so now it's time for you to hold up yours

Rimuru: I honestly think you guys cheated somehow but I have no way of proving this so whatever

Rimuru opened a portal

Rimuru: Just to be clear I'll change the story but not entirely some things will stay the same like motivations to be strong but I won't allow you guys to contact me you'll get what you get

Ramiris: It's alright Rimuru we trust you

Veldora: It'll be no problem for my sworn brother

Rimuru blushed a bit

Rimuru: Right well I'll be going now

Rimuru walked through the portal at this moment in time he had no character he was merely a spiritual prescience that could alter reality

Rimuru: (There was always one thing I myself wanted to change about this to make it better so I guess I'll start with that and then I'll start as a human)

Rimuru used his power to alter the world in the slightest by rushing the birth of a healthy baby boy

Rimuru looked at the parents happy for them as the father left a demon attacked the family in the night

Rimuru: (Forgive me for not saving you but your child will survive this man needs a martyr to become a demon slayer I hope that you can forgive me for allowing this to happen Yoriichi Tsugikuni Now lets preserve your direct bloodline and mix it with another's to make our favorite sibling team far stronger)

Rimuru altered fate by ensuring Yoriichi's son survive out of fear for his child's safety and duty to become a demon slayer to save lives he left his child with his friend Sumiyoshi after saving him from a demon Yoriichi passed on the dance and the earrings Sumire ended up marrying Yoriichi's son and with that, the bloodline of the strongest Demon Slayer was preserved

Rimuru: Alright let's skip a few and enter the story I hope I'll be able to make a good older brother

Rimuru altered the world yet again to be born as the son before Tanjiro and to be known as Rimuro Tsugikuni despite looking slightly different than his siblings by being born with blue hair and yellow eyes he was still loved just as much

2 years later his brother Tanjiro was born he was quite different from other children he seemed completely emotionless he didn't cry when he was born he could see the inside of bodies and he was born with a very large and noticeable Red Mark and he was physically capable in most tasks he was assigned only Rimuro knew what this was a sign of and it was just how he planned

Their other 5 younger siblings were born as well though Tanjiro didn't speak often he still had his kind personality and he let his acts of kindness speak for him he and his brother were always helping others their younger siblings looked up to both their brothers as their heroes for a long time the family was happy until their father Tanjuro died still the family continued to live on in peace thus begins the story of The 3 Angels of Death
