Connecting Sega ID to Xbox One?

I have a JP Acoount for PSO2, do you think I'll be able to us that or have to start at 0?

Start over.

I wish i could use my JP account, but unfortunately, it will be a fresh start if you want to play on the NA servers as they are not connected with the JP servers in any way.

@Xephyrex9240 Thought so, thanks mate.

My question is this, did anyone see a prompt for that when they started the CBT? Will you see a prompt for that today?

The answer to both questions is no.
