Solyx, the new demon king somehow got himself in debt. To pay off his 1 million dollars owed to the IRS, he decides to open a burgers restaurant for demons. Having his upper moons work for him to have his business succeed, or fail.
Kokushibo (male)- Upper moon one (Occupation: Chef) (Has six eyes) Kokushibo is reserved, silent, and aloof, maintaining an aura of unnerving tranquility and mystery that complements his position as Upper Rank One. He rarely speaks; when he does, he talks in a slow and emphatic manner that gives more gravitas and authority to his words. He is an adamant rule-follower and punctual, and he shows a great deal of respect to the hierarchy of the Twelve Kizuki. Kokushibo is shown to be humble as well.
Doma is outwardly friendly and cheery, possessing an approachable and charismatic air. However, in truth, he has psychopathic tendencies and adopts sick beliefs and habits, because of his carefree and waggish persona, he was prone to facetious and inappropriate behavior.
Akaza was a headstrong, stubborn, and battle-crazed social Darwinist who enjoyed fighting, especially against strong Demon Slayers. Akaza had a deeply rooted psychological need to become stronger, and while he usually respected the strong, he did not get along with his fellow Upper Ranks, seeing them as his rivals
Gyutaro was cruel, ruthless, petty, and envious of anyone blessed with a better life than him. He developed a habit of sarcastically complimenting a person's best traits.
Daki was a very arrogant, dismissive, and sadistic person. Despite being over a hundred years old, Daki displayed childish and bratty tendencies such as throwing tantrums, crying hysterically when things didn't go her way, and lashing out against anyone to vent her frustrations
Unlike most demons, Nakime was not particularly violent or sadistic, and instead is aloof and taciturn, almost never speaking and displaying little to no emotion or will outside of obeying orders.
Muzan is dead. Crazy, right? The demon king himself, dead just like that? It must be fake. But it's true, nobody really knows what happens, neither does Kokushibo, the upper moon one and strongest demon behind Muzan. But now that Muzan is dead, every demon should be dead too, no? Well, no. While kept hidden, Muzan had a son who he converted into a demon, Solyx, who was basically known as the demon prince. Now that his father was dead, that basically made Solyx the demon king, but in all honesty, Kokushibo would prefer death than to work under Solyx.
Don't get him wrong, Solyx is a decent guy, except for the fact he murdered half of the demon population, not because they angered him, he did it for the fun of it, not to mention the fact he's not interested in making more demons like Muzan was. Not so surprisingly, Solyx kept Kokushibo alive, not just because he is the strongest demon under him, but because Kokushibo, like his father, is Solyx's favorite. As for the rest of the upper moons... Solyx just kept them alive because they keep him entertained.
Somehow, someway, Solyx put them all in debt, why do demons need money you may be asking. Well, there isn't a reason, Solyx is just an expensive demon and loves spending human money on brand new outfits for himself. And so, Solyx came up with an amazing idea to get out of debt.. sarcasm.
Solyx stole some of Kokushibo's money and opened a burgers place.. called Burgerz, creative.. sarcasm. The thing is this burger place wasn't any normal restaurant, it was one specifically for demons, since they only served human meat. Solyx was obviously the manager, a bad one, but a manager. Kokushibo was the chef, Daki and Gyutaro were waitress and waiter, and the rest of the upper moons brought the meat, it was a simple but steady business, if it wasn't for the fact the demon king and upper moons were running it.
The restaurant just opened as Kokushibo put on his apron and glanced over at the tickets that Daki and Gyutaro brought him, quite a few orders already despite just opening. He couldn't believe him, upper moon one, the strongest demon to live for centuries under the demon king, was reduced to a chef who served greasy human meat burgers. What has his life become.
"Sometimes I wish Master Muzan was still the demon king."
Kokushibo thought to himself as he flipped a patty over the grill.
