Kostya is a character appearing in Professor Layton and the Diabolical Box. He is found on the west side of the town of Dropstone. He is found in the area with the windmill.



He has white hair and black eyes. He wears a white shirt under a brown jacket, along with blue pants and red shoes.


Kostya gives Layton and Luke a couple of puzzles to think over: "Painting the Flag" and "World's Best Golfer".


Kostya is an elderly man who was around at the founding of Dropstone and has lived there ever since. Before that, he lived in Folsense, and because of that, talk of curses and monsters tends to make him a little jumpy.
