Does anyone know where the fuck Hakagakure Is?

Spoiler:

Regal clearly wasn't following, not because it was confusing but because that calling from earlier was back. They were close and Regal personally was now in a rush. That is good, how about we worry about that when we get there. With his next step he would open his first gate while releasing a bit more energy than usually released. So try to keep up. He would say bursting himself forward at A-rank speeds towards the direction of the lost castle. Now if Yvette wasn't able to keep up, then Regal might have had to high hopes for her and he would have to reconsider her being the lord of the group. He would just have to wait and see how things would turn out.
