Help with Datamining Story Scripts from a Unity Gacha Game Before Shutdown

[itaruchigasaki]

Hello everyone! New member here because I'm kinda desperate and I need someone who can teach me fast.

I'm trying to extract the story scripts from a Unity-based gacha game called Stellarium of the Fragile Star (廻らぬ星のステラリウム) before it shuts down on March 10, 2025. The game is pretty unknown outside of Japan, and I haven't seen any JP fans working on datamining it, so I feel like I have to figure this out myself.

I have basic programming knowledge and I use AssetStudio and Charles for this datamining project. I've already managed to rip all assets (models, images, etc.) but I can't find the actual story text scripts in the bundles. I suspect it's stored in an encrypted format or hidden behind addressable asset links.

Does anyone have experience with extracting such data? Is there a way to view all story data without having the story or the cards unlocked in the game? Any guidance would be greatly appreciated! Please leave a comment with your Discord account, and I'll reach out! I'm also willing to lend my account if you need to see what the game looks like. Thanks in advance!

PS: I have no intention of selling or pirating this game in any way, I just want to preserve its assets and stories in a public wiki archive for fans so they don't become lost media before it's too late.

Hi! I know this is kinda late now, since the game should already been shut down by now, but did you ever get what you needed? I look online and see that this apparently is an Otome game? Meaning that It rely on story script a lot right?

I haven't have the chance to search for this, but what engine does it run on? Unity, Criware, Havoc or something else entirely?

Hiya again, probably just talking to myself atp, but I have done my research regarding about the game.

So while I cannot get anything outof the game file with the server downloading the data, what i did find however was already-ripped assets from all across JP forum for this game.
