I have a question: I started the game with the match against Raimon 1. But I didn't continue with Teikoku. Yes, I did the match against Holy Road All Stars. And then, against The other Holy Road team (with Yamato) and finally against Zero.

So, after those matches, I wanted to do the Chrono Stone's. But there is a door on the map and I need a Key.

My question is: How can I get this Key?
