Well yes the end goal is Ryukyu so yes it is the goal they are all chasing for, it is one of the driving forces that keeps the plot together. But that does not mean they are not going to get sidetracked along the way? It wouldn't be much of an adventure then would it? But in the short term for now Ryukyu is a far off dream for most of them. Because even getting there is going to take one hell of a miracle. What I'm talking more about is if we bend our pseudo history a little bit I don't think the time police is gonna come and kill us yet... I hope not because then we will not survive.
