The Days the Port Mafia's Gravity Manipulator Became a Demon King

(Now under contract. Below the blurb for this book, you'll find my upcoming novel, The Zoldyck Business Empire. Please support it! Thank you. Schoolwork and other responsibilities have kept me busy since the term began, so I can't promise daily updates. I can promise I won't abandon the story, and I'll update whenever I have time.) Blurb: The Port Mafia's gravity user is hit by a white ball that falls out of the sky. The little white ball calls itself his Supporter and says it's here to help him become a Demon King. Chuya doesn't believe it at first, but then he's summoned as the Demon King to various alternate worlds. The little white ball tells him that he can't go home unless he becomes a true Demon King. With no other way to return to his original world, Chuya has no choice but to accept the white ball's threat. But why are all these people treating him like a wishing machine? To become a qualified Demon King, Chuya begins his journey through other worlds. The white ball tells him that, as a Demon King, he can summon creatures from other worlds to help him. Half-convinced, he follows its instructions and summons an otherworldly creature. A flash of light later, the one who appears is the boss he respects most. Chuya's eyes fly open. How did my brilliant, mighty boss turn into a Thumbelina?! After seeing his boss in Thumbelina form, Chuya thinks he's already learned to accept anything. But then a white-haired man wearing a black blindfold, also in Thumbelina form, starts demanding that he remove the technique placed on him. Chuya decides being a Demon King is hard! One-on-one ending, paired with the strongest white-haired Jujutsu Sorcerer. There may be a secondary pairing.

Although it's called a library, there isn't a single book inside. There are only rows of doors. After stepping through one of the doors and seeing the bustling world beyond, Illumi follows the library assistant's guidance and comes to a conclusion: being a businessman is better than being an assassin. From then on, the Zoldyck family's development takes a completely different direction.
