Steam Detectives

Orphaned boy detective Narutaki finds himself up against a tour-de-force of thieves, tyrants, and an archenemy who may yet prove more than his match! With the city overrun with crooks and villains of all breeds and creeds, Narutaki must protect Steam City at any cost from those who would destroy it with their nefarious desires.

The villains of Steam City are back at it again! First, Crimson Scorpion has an ingenious plan to steal a pair of priceless black diamonds by seducing Detective Onigawara. Then, Ling Ling's crafty sister Lang Lang is determined to be "an angel in black" for a sick little girl, fulfilling her last wishes... even if it kills her!

Steam City is under attack! A chance run-in with Dr. Guilty turns Ling Ling into a hostage. Narutaki springs into action, but when the doctor reveals the damage he intends to unleash, it becomes clear that much more than a friend is in danger. Yet Dr. Guilty isn't the only one with Steam City in his sights. Knight Phantom emerges from the shadows and promises to destroy the entire town - unless Narutaki agrees to own up to a dark secret from the past.
