Sometimes you think you're lucky, but indeed you're cursed. When you think you're damned, you're one hella lucky person. You might get confused like Mike and Karen does. But you'll get used to it.
Mike received an amazing ability when he reached 17, followed by his sister Karen both of their ability was believed, ancient. The ones who had it hundred years ago are those gods praised by the egypt, Caesar and Emperors who slaughtered his or her people. It was so powerful that it could wipe out the entire world, if it falls into the wrong hand.
Avoiding that to happen, the ability created a being, it doesnt really has a shape or a name, but Mike and Karen named it Hayster. They didnt know what it is or where does it come from, but it sure is part of the ability it self. Hayster trained them, giving them the knowledge they need, and preparing them, because in the past, people who had this ability, was believed that they were cursed, and need to face the curse themself. Mike and Karen wont be able to fight it, Thats why the ability created Hayster to help them, but Mike and Karen doesnt really know about all of this, they're in great threat. But they believe that they will make it, or wont they? In such confusions, they were trained by the ability themself, but such training wont risk our lives, right? said Mike in a worry.
