There's someone in my house. Someone I know, seen on my screen, and yet--never met in real life.

He's come, and now claims my couch as his. I'm left with questions that go unanswered :  What is he doing here? Why is he in my world, how did he get here, why me? Why is it me that he's come looking for.

It's now my responsibility; for the world, to help him assimilate. But what's this? More demon's have appeared, and all of them are here for me?!  WHY!?!

You were absolutely slaying YAMINABE!! on Master level , every note is perfect , every beat flawless. Your thumbs were on fire. "Holy shit, I'm a god!" you thought... until you felt something brush against your foot. Bark... bark? Oh no. Before you could react, a dog started chasing you like you owed it money! You sprinted like your life depended on it, instantly regretting skipping P.E. all those years. Finally, the beast stopped. You, triumphant and out of breath, turned back to mock your fluffy nemesis then beep-beep! Bright lights. Pain. The world spun. "Ahh f-fuck... mama... help me... I didn't even get my limited edition figurine..." Darkness. Silence. Then You woke up in a forest, surrounded by trees and confusion. Floating in front of you was a glowing green tablet. Wait. That tablet looks way too familiar. Isn't that from Scum Villain Self-Saving System?! Turns out, you've been reborn in the Demon Slayer world... as an immortal magical creature with overpowered abilities. /////// Special thanks to @IntoxicxtedHoe also known as Lexi for the cover !!

As Long as I Have You by NaLu911

Izuku We had our entire life planned. We were going to continue to climb the ladder, get married, and have a family. But the longer we were together, the more followers we had, it all started to fade in the background. It was photoshoots, restaurant openings, trend after trend, and eventually, I had less time to see my family, less time for the things I had wanted to do. When I got a strange DM from a guy, warning me about the man I sleep beside every night, I ignored it and trusted him. But when I got ahold of his phone for the first time in years, it was hard to ignore what I already knew. Katsuki I love my life. I have great friends, a good family, a job that even on the bad days, I still look forward to. The run-down one bedroom house that three of us share isn't exactly my favorite thing, but it's home and sharing it with Denki and Eijiro makes it feel more live able than it really is. Money's tight and we don't have a lot, but we have love, loyalty, and friendship-something that's increasingly harder to come by in LA. The DM I got from an apparent rising influencer is proof of that. On top of the various platforms he uses, his entire Instagram page is dedicated to him and his boyfriend. When he DM's me, I shoot him down and even threaten to steal his man because if he won't treat him right, someone else should. ⚠️TRIGGER WARNINGS⚠️ Alcohol/Drug use Cursing Cheating Abuse Smut

Once a slave, you were sold off to a Daimyo (Noble Lord) that saw potential in you. You were 4 at the time, growing up you would disguise yourself as the male Heir to the trading empire your adoptive father owned. You lived in peace on the coast, meeting with your adoptive father's clients. Since you were young, you picked up languages that other visiting traders would use. Your father noticing how bright you were, kept your identity as a girl secret as you continued to help out in his trade. Once you reached the age of 14, your father suddenly fell ill and into a coma. Being his only "Son" and heir to the trade empire you branched out in different goods, specializing in clothing designs inspired by many different time periods. But, what if Demons start messing up your plans and throwing everything off the rails? How will you deal with them? Will you gain their respect or will you die trying? Does not follow the storyline of Demon Slayer exactly, but the same characters will make appearances. I do not own Demon Slayer, This is just a work of fiction. I however own the story I write.
