is a minor character in Professor Layton and the Last Specter
Sebastian wore a creamy-white jumpsuit over a red shirt with black buttons and tinted glasses.
A man who used to work at the steam-engine factory, Sebastian's gloomy appearance contrasts his delicate hobby of rose pruning.
At home, he keeps two pet goldfish from the marine research lab to starve off loneliness.

Sebastian gives Professor Layton and his friends a couple of puzzles while they explore Misthallery. These puzzles include "Light Height" and "How the Bells Toll."
