The Demon Princess: An Iruma-kun OC Fanfic by EikoTheBi
87 parts Ongoing Mature
"Okami", as she calls herself, is Derkila's daughter who was abandoned in the human world by her mother at a young age. She's found her way into the Netherworld, determined to keep the identity of her parents a secret. Enrolling into Babyls Demon School, all she wants is to be a normal schoolgirl... But, of course, fate wasn't going to allow that. ----------------(art in the cover isn't mine btw, credit goes to the owner) Hi! This is my first fanfic, for Welcome to Demon School, Iruma-kun! Or Mairimashita Iruma-kun! Hope you enjoy my cringy crack writing! (No, seriously, 90% of the draft is written at ungodly hours when I can't sleep, which is a LOT) Also, later on there's quite a bit of trauma, angst & violence so TW! There are a LOT of spoilers that I forgot to mark, I wouldn't suggest reading this unless you're pretty far into the manga. So far in my draft I have over 68k words so my publishing of chapters will be a little all over the place because I'm a perfectionist and everything must be ✨immaculate✨ If you have any suggestions, things you'd like to see in the future or simply just wanna share your opinion, I appreciate whatever it is! Also, if you have any random or not so random questions for me or for the characters, feel free to ask in the comments and I'll do a Q&A chapter when there's enough. So, without further ado, happy reading! (This is fan fiction, so I do not own the characters or story of the original series.)

Being a popular singer isn't easy at all but being a Siren is even harder. Most humans are drawn to the song a siren sings. What about demons, tho? That was something Iruma was about to find out soon, as his parents sold him away. He was adopted and didn't mean anything to them to begin with. Too bad that this was just the beginning of the little siren's adventure through the underworld. A/N: Feel free to correct my bad writing. Rights on the pictures go to the artist.
