Chinese Billionaire Pays $8 Million To Hire Japanese Porn Star To Be Personal Assistant For 15 Years | Celebrity — Estimated Net Worth & Financial Dossier
Executive Summary:
It has been said time and time again that money can't buy happiness, but if you have enough of it you can purchase a reasonable facsimile. Just take a look at the mysterious and quasi-anonymous Chinese billionaire who reportedly secured the services of Japanese adult star, Rola Misaki, on a 15-year basis to serve as his personal assistant and protégé. And it only cost him about $8 million to do so, which might sound like a lot until you think about two different factors: A. He's a billionaire, and B. She's a famous porn star, with a particularly fervent following in her native Japan as well as China.
Things get even weirder from there. No one seems to know exactly who this Chinese billionaire is, and he's taken some interesting lengths to keep it that way, having been photographed with Misake wearing a mask. He's rumored to be an entertainment industry figure, known for his big spending, so perhaps those with a working knowledge of Chinese show-business billionaires have a good guess of what his actual identity might be. For the rest of us, we'll have to settle for his nickname for now – "Serious Brother."

Similarly mysterious are the actual terms of Serious Brother's contract with Rola Misaki. The $8 million figure comes from reports that Misaki was hired for the sum of 1 billion yen, which sounds even more impressive than the dollar amount. As for what the terms of this 15-year contract are, no one knows for sure, although the obvious conclusion to jump to is that this guy has hired a porn star as his own personal friend with benefits – hopefully, these two crazy kids make it work for at least the span of the contract. The legality of this arrangement evidently isn't much of a concern in China. Despite a government that openly censors internet communication and other forms of political speech, it's actually pretty lax towards both porn and sex work, so even if it became an open fact that Serious Brother was paying Misaki for sex it's unlikely they'd face any kind of legal action.
In case the idea of Rola Misaki trapped in some Chinese Citizen Kane's castle for 15 years is too depressing for you (as it is for many of her fans on social media), you can take solace in the fact that the contract also reportedly includes language for Misaki to explore an acting career, as encouraged and sponsored by Serious Brother. She's probably the only actor in show business with a 15-year contract who's also working as a "personal assistant," but $8 million probably cancels out a lot of coffee runs.
Primary Income Streams & Multi-Million Contracts
Of course, when you think about it, eight million bucks over 15 years really isn't that much, especially if you're already a famous porn star. But it must have seemed like a good idea to Misaki, especially since "porn star" isn't a profession known for its longevity. Her expenses are probably covered too – and hey, 15 years of this can't be that bad, can it?
