I gotchu fam. Libellule is the right path to go assuming that you're using their RPGMakerMV Game Hook Patcher. The problem is, to use the patcher, you have to first have a www folder. As far as I know (which isn't much tbh), all MV games usually have a locale and www folder. This game is apparently an MZ game which means that there's no www folder and all the stuff that's usually in it (like Swiftshader, System, Icon, Audio, Effects, etc. but most importantly js) are just lying about normally.
So, all you gotta do is create a folder and name it www. The folder called js is where a bunch of plugins are and that's where Libellule's patcher is trying do its work. So, after creating the www folder, move the js folder in there and then run Libellule's patcher. After that, go back to the game folder and take the js folder back out of the www folder. Lastly, go into js and then go into the plugins folder. In said folder, there should be an application called cliploger. Open cliploger and then run the game. I tested this and it worked out for me.
If my instructions weren't clear enough then it essentially looks like this:
Step 1: Download the game and extract the zip file.
Step 2: Download Libellule's patcher (assuming you haven't already).

Step 3: Go to the extracted game folder and create a folder called 'www'.
Step 4: Move the 'js' folder into the 'www' folder.
Step 5: Patch the game with Libellule's patcher.
Step 6: Take the 'js' folder out of the 'www' folder and place it back where you found it.
Step 7: Open the 'js' folder and then go into the 'plugins' folder. Open cliploger.
Step 8: Run game.
Whenever you want to run the game again, just repeat steps 7 and 8. Assuming it all works out like mine, you'll open cliploger and then the game. The game will give you a message saying that it can't find cliploger or something along those lines. Just ignore it and move on to the game. And that's it. If you need more help you can go to the thread that I linked in step 2.
