Super Robot Ninja Girl

Set out on an epic quest to save Japan from an evil yakuza corporation! After the police has utterly failed at doing their job, the only hope for mankind is a mad scientist transforming the president's daughter into a war robot. But, alas! Enemies are already at the gates of Shinjuku Palace Gardens! Fight your way out of the imperial palace and all the way into the heart of Tokyo's red light district where you will encounter the mafioso himself in an intense danmaku battle!

Originally made for the GMC WHAM No.2 in a week, Super Robot Ninja Girl is Japanese in two ways - design wise, and gameplay wise, being a danmaku/platform shooter hybrid, both genres originating in Japan. Originally posted here.
