Nachigami Ine for Sunamori
The foot under chin concentration pose on the edge of the boat in the middle of the lake ^^
As far as I know the pose originally comes from Kung Fu but nowadays it's very popular among contortionists and even rhythmic gymnasts.
I don't know how difficult that pose is but it seems like the ultimate pose for the training of balance, since it must really confuse the vestibular system of the human body :D
Nachigami-san is a female ninja (kunoichi), the background was inspired by the traditional paintings by Koichi Okada (mountain Fuji, of course).
