This is a particular kitbash of mine, which I've lovingly named the Asura.
Essentially, I've combined the HGUC Sengoku Astray Gundam with the Gundam AstrayRed Frame (Flight Unit) backpack, flight unit pack, and weapons. The big sword is the Caletvwlch sword system.
1) This is the whole kit, laid out with all weapons removed. I actually prefer having the normal Astray backpack, rather than the "shield mask."
