    Suzuki Iruma and Ryūko, human (though Ryūko maybe half-demon), 14, one day found themselves taken against their will into the world of demons. To add to their predicament, their doting owner and self-appointed "Grandpa" is the chair-demon at their new school. In order to survive, Iruma and Ryūko must deal with two haughty students who challenges them to a duel, a girl with adjustment issues, and so many more scary beings! Can this duo of an ultimate pacifist and a cold fighter dodge and fight the slings and arrows that are flung their way? As they struggles frantically, Iruma and Ryūko's innate kindness begins to win over enemies. DISCLAIMER: Welcome To Demon School! Iruma-kun (C) is created by Osana Nishi. The following characters, excluding Suzuki Ryūko and Félin Lavande, belong to Osana-chan. I have no rights to claim any canon characters of the anime as my own as it it considered plagerising. Also, big thanks to PikaBlaze (DeviantArt) for being the reason I started this story as I was astounded by their story, causing me to try and use my characters in the story.

But when Iruma approaches you having no idea about you're bloodline... how will you react? Btw my recent chapters were ahead of the anime. I made this fanfiction for entertainment purposes, I gain nothing by making any of my fanfictions, please enjoy reading this.

    She has gone through two lifetimes. This was currently her second life. She has a system. It wasn't any Ciel from Tensura but it was something. She can exchange points for skills or magical abilities from various different anime characters. As long as she knows of the anime character, she can copy something from them. But not without a cost. She gets a trait from that character every time she copies something from them. For example; If she copied Mereoleona Vermillion's [Flame Magic Proficiency] she'd get a trait from Mereoleona, whether that be personality wise, habit or hobby. (Fun fact, She chose to have Mereleona's appearance for when she was reincarnated into this world. Why? Because she can) (⁠ ⁠╹⁠▽⁠╹⁠ ⁠) She gets daily points. No quests or anything. Just points for simple things. Honestly it felt like the system was just made to make sure she had good mental health and took care of herself but she's not complaining. --- Hell on Earth. That was your motto for your job. Granted, you knew there was an actual hell, considering the shit you had seen in your life. And the fact your coworker was a child. A child named Suzuki Iruma, in fact. A boy who looks eight but is actually fourteen. A kid who's life was decidedly worse than yours, but yet he smiles as bright as the sun despite everything. It wasn't long after meeting him that you decided you'd be his mother. You'd do anything for him. Including summoning a literal demon and signing your soul away. But as it turns out, hell (Which is called the Netherworld) was a lot better than living on earth. Demons were more humane than a lot of humans you knew. And Iruma's smile wasn't the only one that would change your life. Her name is Rinka. ---- There is a ship! It's a Balam x reader!!!! Why? Because Author-san said so! Don't like it don't read it. Keep comments respectful please! Hope you enjoy!
