I Shall Build an Army

Now I am sure you have already read the story of a normal person being sent to a fictional world with a system that makes them absolutely overpowered. The thing is, this story is a bit different. For the Main Character will not go around beating people up just on his own. No, this one will go around beating people up with an army, an army of fictional characters summoned through a System, the Gacha System. I will also post this story on RoyalRoad and Fanfiction.net
