    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.

    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!
