Hazuki is a minor character of Ginga: Nagareboshi Gin.
He's the brother of Kisaragi, Minazuki and Uzuki, and the great-uncle of Harunobu, Hiroshi, Kuranosuke, Masami and Masaru. In the Manga he's the uncle of Denshichi, Izō, Kazuki, Miu, Saburō, Shinsaku, Shūsaku, an unnamed brother, another unnamed brother, and ten other brothers. In the GDW Anime he's the uncle of Izō, Kichinosuke, Kogorō, Shinsaku, Shintarō and Shūsaku.
Hazuki is a Siberian Husky with pale brown eyes. He has black ears and stripes on his face. He has dark brown muzzle and back. His belly is pale brown.
In GNG anime, he has blue eyes, black markings, and a blue-grey belly.
Hazuki is the moot aggressive and impatient of the four brothers. He is brave but reckless fighter. He makes a foolish move by attacking much stronger Moss, after calling him fat. He sneers at the Ohu dogs when they walked into their trap. He also laughs at Terry after he died, saying that he had pathetic life and pathetic death.
He is fetched by Chūtora and John to help in conflict against Reima's wolves. Moss leads their army into Reima's palace. The Husky brothers help Kurotora and defeat Raiga with the help of Moss and Hakurō. After Reima explains the dogs that their true enemy is the evil wolf lord Gaia, the Four Heavenly Kings swim to Hokkaido to fight Gaia's army. After the battle, they return back to home.
Hazuki does not appear in the series as he has been "dead for long", according to his nephew Izō. However, he is very briefly seen in a flashback along with his brothers, resolving a conflict.
