Ripping One Piece Bounty Rush models and sound?

[otchi]

So I've been exploring ripping One Piece Bounty Rush game. Resources are downloaded into the device with every update so I'm assuming all the data is just in the device. I located an Asset folder in the game, and I used Asset Studio. I was able to find textures and PNG images, but not models or audio. I've already searched if there are other threads on this, and I coudln't find any, so I'm wondering if anyone has any tips on this one?
