Ep. 21: Keaton dan Taihei menyelidiki emblem dandelion pada arloji dan botol whisky di Edinburgh.

In Edinburgh, Taihei brings a bottle of sake to Keaton inside a bar. After ordering a bottle of Scotch whisky, Keaton explains to Taihei that he is waiting for Professor Amada to show up so they can compare the two bottles. Keaton shows Taihei a Scottish antique watch engraved with a coat of arms and stored in a box, which was previously preserved in a Japanese shrine. Tasked to find the original owner of the watch, Keaton points out to Taihei that the box and the coat of arms both feature a thistle. Keaton previously went to the National Archives of Scotland and learned that the coat of arms might have come from Strathspey. He surprisingly found out that the bottle of Scotch whisky features the same coat of arms. Upon discovering the history of Angus T. Charmichael, known as the Lord of Scotch, Keaton did some investigating. Keaton tells Taihei about the tragic life of Angus during the Reformation, detailing his orphanage in a monastery, his grievance over the death of his lover Ann Macrae and his shipwreck at sea with his servant Fiddich. Moreover, Keaton tells the legend of a tengu from the sea being forbidden to fall in love with a merchant's daughter by an entire village. Taihei realizes that the bottle of sake also features a thistle, but Keaton notices a slight difference with the coat of arms. Amada finally shows up, and it is implied that he is a descendant of Angus. (Source: Wikipedia)
