This is kind of a two part build, because I am building 2 of them. One is Oniya's SD GR5 (
鬼屋へようこそ - Welcome to ONIYA -), the other is the more realistic version available here:

I already finished the Super deformed one:

SD Stratos Turbo.
Oniya did a lovely job, it literally fell together when you start building. Hardest part was the engine cover, with its little steps. Model is around 10cm long.
