Ginga Densetsu Weed: Orion
Gekka is sent to kill Yamabiko together with Kurogane and Shikkoku, but Orion, Heizō, and Tyson come to the site and drive them out.
Later, Gekka, Kurogane, and Shikkoku collide with Rigel, Kotetsu, and the side-switched Masashige. Masashige fights them, and kills the three assassins to protect his comrades.
