_+*Chapter One*+_

Hey guys! :) This is a longer-than-usual chapter you'll find out how many words this is at the end 😅 but I hope you enjoy it!

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

It's been a little less than a decade since then... M/n could still remember the extreme pain of being turned into a demon.

M/n looked down at his hands, still small, then his nails, still sharp, they looked like obsidian they were probably just as sharp too...maybe even more so.

He still had to drink blood but he could drink even less than Yushiro! He likes to rub that fact in the demon's face every once in a while.

In the past decade since he was turned into a demon was probably the best years of his life so far, he loved both Lady Tamayo and Yushiro. M/n honestly didn't know what he would do if he never met them.

In those years Yushiro had been training M/n, making him get used to his new found strength and making use of it.

M/n found out that he was surprisingly fast and he could heal quicker than average, although he wasn't that strong his speed made up for it.

Recently Yushiro had been training M/n how to properly use his demon blood art and how to control it the best he could. M/n really liked Yushiro, he was sort of an older brother figure to him, M/n also really liked Lady Tamayo.

M/n even had clothing similar to Yushiro! Except his shirt was f/c instead of a light gray and his pants were black and less wide than Yushiro's.

They recently got a cat too! M/n was currently playing with said cat, his name was Chachamaru and he was the cutest! Watching as Chachamaru chased after the toy mouse on a string, M/n was fairly entertained.

M/n was left home alone today, he normally doesn't stay home alone but tonight he decided he wanted too, he doesn't know why but he did.

M/n laughed when he saw Chachamaru chase after the fake mouse, she swatted at the mouse with her small paws.

The string stopped moving as he heard the door opening, Lady Tamayo! Yushiro! he quickly got up abandoning both the string and Chachamaru.

he ran towards the door, his socked feet softly padded against the hardwood floors. Making sure not to go too fast. "Tamayo! Yushiro!" he yelled out but all of that excitement vanished when the two, four..? People came into view.

"who are they?" he pointed at the unconscious pair, a man- no demon and a lady.

"something happened while we we're out..." Tamayo looked to the side, she looked worried and so by default M/n became worried to.

"what happened?" he walked closer to the pair, "Kibutsuji was there and he turned this guy into a demon" Yushiro answered this time.

"Muzan...?" M/n's expression grew fearful, he looked over the seemingly sleeping bodies.

"what's that guy doing here!?" M/n raised his voice in confusion, gripping the side of his head. M/n has never seen or met Kibutsuji but he knows that he's a bad demon, the worst if you will.

"we don't know...but now that he's here we need to move again.." Tamayo made her way to the clinic part of their house. M/n followed her the whole time.

"hwahh!" Exasperated, M/n continued "again? it feels like we just moved here though...!" M/n whined as he watched Yushiro set down the uncurious lady onto the medical table.

"it'll be okay, i'll let you pick out our next location" Tamayo said whilst she set her hand on M/n's head, gently petting him.

All of a sudden he longer felt as upset as he was a few seconds ago "Really?!" he looked up at Lady Tamayo as she lifted her hand, excitement written all over his face as he racked his brain on where he would want all of them to live next.
