That, is impressive...
I doubt it would be possible to edit the intro? Alternatively, just have someone translate the script and voicematch the announcer to also take into account the Japanese version only features.

Speaking of which, I have found a "beta version" of v1.18 hosted on Myrient (via hShop), that doesn't actually work with the patch?
It's been a while since I come across this on the Teknoparrot discord server (which I left, because of "certain reasons") and with AI translation being a thing these days, I'm surprised that no-one has actually jumped on this again to do all the rank titles.
Though, I guess people are still... holding out for an English dump.
