If you are wondering what the picture is about here it is :
(Based on a japanese legend)
When Yoshitsune was a young boy going by the name of Ushiwaka-maru, his father, Yoshitomo, was assassinated by the Taira clan. Taira no Kiyomori, head of the Taira, allowed the child to survive on the grounds that he be exiled to the temple on Mount Kurama and become a monk. But one day in the Sōjō-ga-dani Valley, Ushiwaka encountered the mountain's tengu, Sōjōbō. This spirit taught the boy the art of swordsmanship so that he might bring vengeance on the Taira.
