A young master in a mansion deep in the forest...?
About
Europe, in a time long past. In the town of Elseria near the Royal Capital, rumors swirl of a mansion deep in the forest where a master and butler of unknown origin reside.
To produce an heir for his master, the butler advertised a party at the mansion. However, the townspeople found it eerie, and the only one who showed up was Guest, who was unaware of the rumors. Delighted that even one person came, the butler welcomed Guest with open arms, leading Guest to live at the mansion.
As time passes, it becomes clear that the master is a world-renowned detective sought after by the Capital and other nations alike.
Will the master and Guest eventually be united...!
