Idea Factory .be (Unity) files (NepNep Chaos Chanpuru)

[ApocFish]

I've been looking through (PS Vita) NepNep Chaos Chanpuru's files since, while some of its assets are online, a large portion of its assets aren't. These assets seem to be stored in .be files in the StreamingAssets folder, which as far as I can tell are Unity archives, but I can't access the contents of them.

Here's a .rar archive with a couple examples: https://files.catbox.moe/jx8c45.rar

If anyone has any insights, I would appreciate it.

From what I've been able to gather from looking at the files with HxD, they seem to be a variant of CAB-* files--perhaps encrypted somehow? The version of Unity that was used to compile them (and the rest of the game) was 5.3.5p6.
