Mam I love azumanga, if anybody has any model of this series pls share it, I want to make and archive any model that there is, specially the PS1 game models.

What a coincidence. I am currently in the process of ripping the models from the game. Almost figured it all out.
If you don't want to wait, you could use the debug mode and use Avocado emulator to rip the model scenes yourself.

Oooh yes I would love a little osaka for my desk :)
