Ok, for everyone having problems with this game, it feels like it's similar to Bunny in Black 3 DRM(Protection). Basically, some games are made under region lock with the engine itself and even if u set up ur computer to "Japan", it'll also read the computer time zone and stuff, and if it doesn't meet the requirements, u will be locked or have similar malfunctions. The workaround to play it well is.... download something called "Locale Emulator", google it, it'll add a new thing on ur right button after installing, setup a profile to run as Administrator and configure it to use Japan time(any place like Osaka, Kyoto, etc) then run the game pressing right click and choosing Locale Emulator and the profile u configured with the time zone, the game will run smootly now, even having the right animations as u move the mouse while doing the tutorial for example.
Locale emulator let u create global profiles(as the 2 i made, one to run as admin and not) and also, make a profile for the program itself, this in turn solves the issues of animation and tutorial on my side. Hope this helps u guys.
