The monster realm was much different than the human one, with that separation it was hard to get along and soon a war started, families died, monsters and humans. It wasn't a good time for anyone, children and teens left to fend for themselves while the world wrecked havoc. After years of this chaos it seemed to ease, only for Monsters to hit twice as hard, now enslaving any human they could find as pay back.They took everything from you, well everything that you had worked for that is. It's been about 11 years since the accident happened I was 19 years old currently so that happened when I was 9 I've been alone for 11 years. Taking care of myself and I got pretty good at it to. I hated the monsters, despised them for what they did, but now as I'm alone running away from one, fear was the only emotion flowing through my body.What happens when you get caught by that monster?Disclaimer, no art in here is mine unless otherwise stated in that chapter, all credit goes to original artists.…

This is Glitchtale, but the beginning is different. Instead of Sans being his usual self, he turns into himself from Dusttale, where he killed all of the monsters and gained some of their magic. How will this affect the history of this fusion of 2 timelines, especially when Dust becomes a part of the outcome? And more importantly of all, what other surprises will wait for him when all is said and done, when he is finally through the huge torment?The pictures in the story don't belong to me. Alphatale belongs to Shadikal15, as well as the concepts he has made.https://vibeless15.tumblr.com…

"Even if it wasn't clear, Alphys could see that the human were hiding a smile. That damn smirk. She wanted to destroy it"WARNING! UNDERTALE GENOCIDE SPOILERS!In this story the human who fall in the underground is doing a genocide route, and this is the monsters and Alphys's point of view. Everyone are forced to evacuate and stay in the true laboratory for a while, while Alphys thinks a plan to defeat the human...I want to remember you that this is a fanfiction so if there is something that you think it doesn't happen in the genocide run, like some things the monsters do or how they talk it is for that.-Undertale belongs to Toby Fox…

The Mob Character Shouldn't Have A Yandere Harem?!50 years ago, rifts started to open around the world. Portals to other dimensions. And with their appearance, so did the fantastical monsters that lived within them, led by the ruthless Demon King. Unprepared for them, millions died. But not only did monsters come through, but other species which held magical powers. Four Great Sages sealed the Demon King away in his own dimension, saving the world.Now, the other species live integrated with the humans. Elves, Succubi, Kitsunes, Fairies, and more! Now magic is a commodity, used by adventurers to protect civilians whenever rifts open up.Eric Arthurson transfers to Japan from America, where his sudden arrival will set his life on a course to become a great adventurer, followed with his friends who may love him a bit...too much.That was the synopsis of Heaven's Hell, my favorite anime. It was a yandere harem anime! The only one of its kind! And I loved it!And the night I was going to watch the finale to the anime, the final episode of Season 3, I fell asleep. And the next day, I was in a new place that wasn't my home.I was in Heaven's Hell. And right in the thick of it. Only a couple months until the start of canon.Now I have only one goal: survive. Survive the oncoming events of the anime, and the yanderes of the main character.I was only just transmigrated into a dangerous world with dangerously powerful yanderes! Nothing can go wrong, right? Right?Volume 1 - Heaven's Hell [Chapters 1 - 124]Volume 2 - Death's Life [Chapters 125 - 180]Volume 3 - Beginning's End [In Progress]#1 harem - 7/19/2021#1 isekai - 8/2/2021#1 alternateuniverse - 8/21/2021#1 foxes - 8/28/2021#1 comedy - 10/13/2021 #1 elf - 10/30/2021#1 demons - 12/16/2021#1 original - 9/24/2022#1 monsters - 2/18/2024…
