I'm not too sure how that will work but it's rumors but we won't find out until the game is out but as I said before I will get it 3 days after thanks to the shipping so look out for my late update for that one good god I can just see the crazy stories that might come with this dlc if they do it but I want it to happen we'll just have to wait and see
Don't get upset if this rumors don't turn out to be true it one I was shocked to hear it myself see you later
Btw it's all in Japanese don't ask me
