Rigel is the black-and-white pup of Weed and Koyuki. His color is fairly unusual, for none of his known ancestors are black and white.

As his siblings, he was named by Gin's former owner, Daisuke.

Much like Orion, Rigel has a foul mouth, and he usually yells at his sister Bellatrix. He is the second youngest of the litter.
