They was born with Gin to Riki and Fuji. They were denied as good bearhounds and were left to live with their mother Fuji. When Gin finishes his training with Gohei, he returns home for a brief time. The differences are already obvious when he flips one of them over. After Gin easily jumps on the roof, his siblings try to do the same but fail. Later on, they were seen again when Gin finds his owner, Daisuke and mother, Fuji. They just watched as Gin tells Fuji to take care of Daisuke.
