I want to play this, but I'm always scared that I'm going to change my entire system to Japanese on accident somehow trying to play these games with stupid installations. lol...Whyyyyyy...
"stupid installations" wut ?
literally extract it and play (Installation spoiler has only those 2 steps) , If you are new to RPGM games you will need to install the required RTP.
If you do not have an extractor supporting rar5 then thats another step for you too.
The other steps mentioned in the OP are usually for JP games(with a fan made translation).
The game works fine (at least for me) without changing to or using (a) JP locale (emulator) "on accident :test:" ,but for ppl that may get errors it's mentioned as a possible fix.
