RTA is an abbreviation of a real time attack (Real Time Attack), and it’s a play style of a game….
For example, it will be assumed that you are an RPG, and it was entrusted with 50G and a cheap sword and armor by King. Perhaps you say bad things on the King to be equipped with a sword and armor cheap because it will be an adventure.
This is a story of male Kaito Ichijo with the RTA world record which doesn’t do such proper thing.
