JoJo no Kimyou na Bouken: Phantom Blood model format (P2MD)

[SasdarlH]

Me and a friend are trying to load and extract the model data of the characters from JoJo no Kimyou na Bouken: Phantom Blood. However, the way the game displays models makes them unable to be ripped from the emulator itself, and we haven't been able to open the model files themselves. The actual model data begins with the string "P2MD", and all the data before it is probably container information (possibly?). I suspect that this format is a proprietary format from the developer, Anchor Inc.
It would be hugely appreciated if someone could have a look at these files and help figure out the format.

The file linked above contains some of the folders from the game's files. These were extracted from the game using a QuickBMS script, and as a result the file extensions may not match those originally used by the developers. Folder "1" contains the game's character data list, which includes the original filenames of some of the game's files; folders "18", "21", and "22" appear to contain character model data. Folders "26" and "27" may contain stage model data. It is unknown what the other folders included are used for, but they seem to use the same formats.
