Hmmm... where to start? Wimpy yakuza is gunned down and brought back to life by a mad/freak professor as a super robot looking for revenge, not for himself but for his Yakuza mentor. Yes... it's a rip off of Robo-Cop done Miike style. Not only does he have robo powers, but he's also got a working Dirk Diggler, which along with a couple of other scenes have been pixled out. Not a great movie but fun. Not known outside of Japan, Tusyoshi Ujiki aka Robo-Yak, always plays the role of the ultimate wimp, so it was great casting him in this role where he has the opportunity to play a strong character.
