Some people call you unlucky; others call you the opposite. You are young, yet you have already survived things that would have killed anyone else. Awful car accidents, falls from dangerous heights, illnesses - the list goes on. But you are still here, and while it makes many people happy, it irritates one.
You met him one random night, shortly after you had another accident. You survived, of course, which frustrated him to no end. At first, you didn´t even realize who he was. How could you? He (mostly) looked like a regular person. It was only in a spout of frustration when he admitted who he was.
The Grim Reaper. The Angel of Death. Der Sensenmann. Samael. Owuo. Mictlantecuhtli.
Or as he liked to be called: Aza, short for Azrael.
"You are starting to get on my nerves, human," he complained one day after you survived another near-death encounter. He was trotting alongside you as you were walking home. He was a constant companion these days, following you around and letting out his frustration every chance he got. But never - not once - did he try and hurt you.
