Pink Dragon is a minor character of Ginga: Nagareboshi Gin in the Wolf Arc.
Pink Dragon is a white Hokkaido Wolf. He is very feminine-looking, even so that he was mistaken to be a female by many fans. He has a mane, possibly pink in color hence his name, which covers the other side of his face. Strangely, Pink Dragon's design changes during the manga. Sometimes the pink fur covers most of his body and only his face is white.
He was trained by Juga to be a hakkenshi of Sirius. Just like the other hakkenshi of Gaia, he believed he was a true hakkenshi. He awaits Gin's groups arrival with Blacksnake. He never fights and his technique isn't seen because Juga interrupts the fight between the two groups before it's his turn. When he tries to stop Gin from following Juga, he is knocked aside and eventually defeated by Raiga, Sakon and Ukon. He is not seen again after this and likely died during the earthquake which destroyed the Underworld.
- He is possibly a Zan warrior, as he's not surprised by Raiga's technique unlike the other Hakkenshi of Darkness were.
- In the Japanese edition of Meteor Gin, Pink Dragon is described as an okama (オカマ), a term used to describe a male homosexual or effeminate male. The term rainbow warrior was used in the Finnish edition.
