Hi there, looks like all modern marvelous/bullets engine games made by same publisher are using this same formats nowadays

.LZS zip files with .bum (BUMV2) format models inside them, and .dds textures saved as bc7 linear with mipmaps

I'm from Story of Seasons:A Wonderful Life community, and our game uses same formats as here looks like

We have a tool to unpack .lzs files and repack them, I checked with your file and looks like it did unpack the .bum models and some files called .bc7, i assume those are meant to be texture .dds files saved as bc7 linear with mipmaps, same texture our game uses
we have a rough noesis script that can get some of the bones/skeleton/mesh out of bumv2 models, but its unfinished and can't rip everything yet, weight paints are still broken etc, if anyone out there is interested in helping crack the format and create better ripping tools, can join our sos/rf modding discord here:

were hoping to one day have a blender plugin that can rip the format in or out and make mods for story of seasons games, looks like this effort may be useful to folks in the honey parade and senran kagura series as well!
