Request for Anim engine (Crowd engine)

[Memorizzal]

Hello, can I request Anim engine? The game is this one, English patch. I got a tool for Anim from f95, it dumps to .json too, but its format is too ugly that I can't even look, also I recognized the tool can't dump repeated lines. I have included the script and the tool, I also included a raw script from https://vndb.org/v2607 in case since I can't find raw script of NTR homestay. Anim_stuff.zip

I forgot to tell you somehow the tool only dumps dialogue lines if it is English script
