Shikkoku is an assassin belonging to the Kurohabaki Clan. He is one of the two Kai-Ken trios in Ginga Densetsu Weed: Orion. He is the brother of Gekka and Kurogane.


Shikkoku is a dark Kai-Ken, with slightly lighter urajiro-colouring. He has white markings over his eyes, which resemble eyebrows. He has dark markings around his muzzle, and dark stripes over his face and body. As his brothers, he also has light eyes with black cornea.


Ginga Densetsu Weed: Orion

Shikkoku is sent to kill Yamabiko together with Gekka and Kurogane, but Orion, Heizō and Tyson come to the site and drive them out.

Later, Shikkoku, Gekka, and Kurogane collide with Rigel, Kotetsu, and the side-switched Masashige. Masashige kills the three assassins to protect his comrades.
