The Pseudo Beast Slayer

I made a description, but accidentally didn't save it ;( So basically, the main protagonist is born without much power like regular and wants to become a beast slayer, but needs more power. Beast slayers are highly paid and powerful people. Beasts destroy towns and stuff and effect people's lives in a bad way. The main protagonist is named Alexander. Everyone is born with one power, and rarely born with two. VERY RARELY. So yeah. EDIT: Alexander has 2 powers. Thought that would make it more interesting :)
