Welcome to the P.S.A

His name is Ryan Green. He works for the P.S.A as a secret agent. All his life he trains himself to be even stronger than the rest. He never cried... Well except for the time when he was still a baby. When P.S.A gives him a mission to protect two siblings from the enemy company called, "P.E.S", will Ryan accept the challenge or not? Well of course he will accept it. But there is one thing he was not prepared for. Something I believe he did not expected. High School. Will he survive there? Will he manage to befriend the siblings so that things could get easier? Could he find the guy who works for P.E.S and exterminate him? This my friends is gonna be one heck of a ride.
