If you like myself want to enjoy this game without all the weird Japanese grammar I uploaded a version of the script where I changed all instances of "Mou" (and all other forms such as M-mou) to "Jeez" (or J-jeez etc, you get the idea), helps make everything feel significantly less "anime". No other changes beyond what has been mentioned, this is an otherwise vanilla script and obviously incompatible with other mods that replace the script.rpy file.

Probably a little bit of a niche "mod" I created for personal use but I figured I'd upload it here in case someone else is interested.

In D:\SteamLibrary\steamapps\common\Sunrider Academy or wherever you have this game installed open the folder called "game" and backup your script.rpy file somewhere else on your computer, after creating the backup just drop my script into the "game" folder and you should be fine to launch the game.

Thank you to Force (EMF) for their guide on editing Renpy scripts
A big thank you to Love in Space for making this game
And thank you for downloading this script mod, or at least reading this far
