This is an older work. I'm posting it for record-keeping purposes. Created in January 2020.
I bought AOZ series expansion parts from Premium Bandai, but...the timing for buying anything else didn't work out,
so I just made the expansion parts and attached them haphazardly,
and it ended up looking like an Armed Base.
The original kit is quite large, so when combined, it became an enormous size.
