Gantz the Game file formats

[ChakraWarrior2012]

So the game stores characters inside NKP files, but when extracted it contains NKT, NKM and NKA files. 
Does anyone have any idea how to convert these into usable formats?

Can you attach some sample files?

Here you go, the files of 3 of the characters

Good luck
