The Mob Character Shouldn't Have A Yandere Harem?!

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?
