K-Hole of the Mi-Go!

Levi has just become the world's first trillionaire, with business interests ranging from space flight, to artificial intelligence, to social media. However, when a man he thought was dead appears and informs him he has only 826 hours to live, everything changes. Levi discovers not everything can be bought with money, and enters an unholy alliance with the psychopathic Mi-Go of Yuggoth. As the Mi-Go's demands become increasingly extreme, even the world's richest man has to get his hands dirty in order to survive.
Thankfully, he has plenty of ketamine to see him through it-but nothing fuels bad decisions like horse tranquilisers and hubris.
