What's Different From Date A Live: Spirit Pledge and Spirit Crisis? 

No, you can't switch languages. That goes for most (if not every) JP only game.

You have to use a vpn now. I also created a separate google account and set the region to JP for this game.

@@majingrimlock976 Thanks for the tips, and I did watch how to use a vpn in japan, clear cache, and I have not create a Japanese account yet at Google play. However, I decide to save my money instead just saving a lot of gems when the Nia and Mukuro event is out, and then getting the original ten spirits of the series and later the sephira set, but not getting to the C6.

@@patrickjohnau2647 No problem. And that is a smart idea to save. I am also not gonna try and max out every spirit again. Only my main spirits (for me that's Kotori, Natsumi, Marina, and Tsang).
