Hybridweapons storie

Crow didn't know anything other than how to kill. So he became an assassin, killing people for the right price. For the first few years everything was okay; he did his job right, nobody came after him and he had a loving mother (kinda) But the life of crime, deceit and danger quickly overwhelmed him and Crow decided that it was time to change. But what can he, with his specific skill set, do? Be the complete opposite of what he was taught. Instead of taking away lives Crow will now save them as he chose to be a Guardian. What could possibly go wrong? ...At least he made friends.
