Legends of the Dark King: A Fist of the North Star Story

Kings Understand Kings!

Raoh has his army rebuild the castle within three days and trains them in combat. He sends his army to fight against the soldiers led by Gion the Wise King to take over the kingdom as a means for transportation. However, as Raoh's invasionary force enters into the nearby valley, they end up being trampled to death by a herd of wild horses, said to be ruled by a stallion deemed the Black King. Raoh, Reina, and Souga go to this valley themselves, where they witness the Black King protecting a dying foal against two wild tigers. The Black King and its herd agree to fight alongside Raoh and his army after they both kill off each tiger. After Gion realizes what happened, he surrenders his kingdom to them.
