A Japanese breed of dog called Kishu. He was adopted by Binchotan after he followed her to her house in the woods after she gave him some food from a shop in the town. He was apparently a stray as he had no collar when Bincho met him. He was given a collar made with one of the large nuts seen in the series. He was also given a kennel made with one of Chikutan039s inventions after it broke and failed to serve its intended purpose. After giving him a collar Bincho decided to name him Saji which according to her means 039trifle039. Bincho explains to Kunugi who was present with her at the time that she chose 039Saji039 because the dog had apparently been abandoned as though it was just quota triflequot.
