Hero? I'm assassin, but that's the same right?

Pyro is quite a notorious assassin on Earth, and was enrolled in the 'Black hands' in the 'Arachne' Division as one of the best assassins at that time, and the most secretive one. He has different set of values and in some cases lacks common sense, but as being the one who get the job done by any means necessary was one of the reasons to his fame, or infamy, depending on who you would ask. It's year 2026, and the third world war will soon commence, but before that Pyro has a target to eliminate... or two. *** As I am new to writing and not a native english speaker, there is bound to be mistakes, not critical though mind you. Oh and comedy is there just bacause I will try to make MC funny... and happy-go-lucky... probably... oh and he will be/is OP... There's no point in weaklings, right?
