Tanya

A young Russian girl whom moved into Junpei's main home, forcing his family to live in the barn. She was a very pretty little girl and was tired of being forced to move around the world with her father who was the Russian Army commander. Not much of the hard feelings after Tanya befriends Junpei and Kanta, soon learning how to communicate without just words. It was never made clear if she did have the same feeling toward Junpei, but it was somewhat hinted to when her granddaughter gave Old Man Junpei the sketch book he left on the island.
