I'm going ti say probably not. Your account has a violence license attached to it. The license is what says what version you own. Not your location

Yeah, outside of Japan the only "obtainable" version is the console version, at least without doing some VPN stuff I guess that I'm not really sure on

It is worth noting there is a further censored copy too, the standard Japanese retail version. I'm not sure if this will contain any more potential time saves, this version on steam also shares the same app id as the global version so you can not have both Japanese "low violence" and Global uncensored on the same steam account.

EDIT : While I won't be buying it personally. The further censored version is very easy to get for non Japanese Xbox One owners, because its not rated CERO Z, you can just buy it digitally by changing your region to Japan in the console settings. Possible on PS4 too but it requires making another PSN account. It's cross buy with Windows store on xbox too so you should be able to get a low violence PC version through this method too although dont quote me on that.

While I haven't had a chance to play through yet. I'll be playing through this version some time within the near future, is there any specific moments you want me to keep an eye out for?

EDIT: Also not sure how you'd get the Grotesque version outside of Japan. Its region locked to JP store and CERO Z titles aren't allowed to be sold without credit card proving that the purchaser is of age. This could also cause problems for those wanting to speedrun the console versions as they may not be able to get DLC down the line.
