I would gather up the most beautiful men in the world and make them all put on Kars cosplay. Then, I pick out the most accurate ten. After that, I make them all complete a series of tests and challenges to determine which one will be able to 24/7 larp Kars the most accurately. To greaten the stakes, once eliminated they will be kept in a set of prison cells indefinitely. They will be forced to maintain their physiques and beauty, just in case. The winner will be able to live with me in my lavish castle and be waited on by all my servants. All he has to do is effectively larp Kars 24/7. If he falters in his duties too severely he will be replaced by one of the other Kars until he can get his act together. If the replacement Kars ends up being better at being Kars than he was, the old one will be kept in the prisons forever.
I will also have a team of the world’s greatest scientists working tirelessly to find a way to make me immortal and invulnerable so I can rule the world forever.
