Y/n who has been reincarnated in the chaotic world of One Piece knowing everything that is to happen. I do not own anything except the plot.

What if it wasn't Sullivan who got summoned and adopted Iruma, but the missing demon king Derkila who was vacationing in the human world. The irresponsible king is smitten by the human boy and claims him as his own. Why? Hell knows what's going on in that head of his...

"You are the brightness to my dullness. You are the sugar to my tasteless, bland tea. You are the sun that shines to my gloomy weather." "Don't think so much of me like that. I'm there for you and always will help you. I promise we will do this together. "That is not necessary. I must do this alone, it is my responsibility. Do not get involve." "No! We made a promise and I am keeping it, whether you like it or not. We will do this together. I will not leave you behind. Please, just please, rely on me as much as I rely on you." A shining light emitted from a source. Shadows had surrounded another source before the light overwhelm it. One has warmth and a feeling of ease. One is cold and feeling lonely but also relatively at ease. Light and Darkness coexists with each other. Both balanced each other. He was her light. She felt empty even though she always looked on the bright side, always believing darkness is something to be apart of her and be attached too. He came into her life, along with others, she did not feel it anymore. She felt the loving embrace, especially from him. Comfort and Unity.

(Discontinued) in the demon realm, there lives an app called devitube, well...a demon version of YouTube. and there lives an very popular devituber, who uploads human songs. the misfit were amazed and interested when they first watched it. They watched the one with subtitles by the way. Plot twist: it's iruma who's the famous devituber. Also I'm probably gonna upload this on AO3 once I get an account. this will include swearing and very mature stuff, so be warned little girls and boys. And scary shiz is involved fuckaroos. And also, it doesn't mainly and constantly focus on iruazz, it's like slow burn.

A change of pace and environment can help a person become the person they envisioned themselves to be. When Y/N found out that she was sold by her parents to demons, she wasn't shock nor angry. Rather, she HOPED that her next guardians are nice and better than her parents. For her, it did not matter whether her guardians are animals or demons as everyone is better than her parents. She doesn't need to look farther to search for monsters as they were in front of her-they were with her since the beginning. Now under the care of demons, there she learned family secrets, the wonders of friendship, the much-needed character development, and of course, Falling in love. === It's time to feed my fantasy shit.
