Prologue
Yung & Xia
Here stand the most powerful of all hierarchs excluding the existence of Gamja. They are both the blood children of Gamja himself. Before their birth, Gamja wanted to develop a new generation to continue his legacy when his time had passed. Unfortunately, he had no female companion at the time. As a result, he forced a previous hierarch by the name of Kemuri, a smoke goddess, into submission. Nine months after her forced submission, she gave birth to twins, one boy, Yung, and one girl, Xia. The mother, Kemuri, was then executed by Gamja himself, in his eyes, her work was done.
Psychology states that every child is born innocent. That statement does not apply with these two. Together, they both killed their first victim at the youngest age of 2. From there Gamja began to train his children, having them learn the deepest secrets that he taught no one else of the ninjitsu style. He vowed to make them the greatest ninjas in the clan. Unfortunately, it was Mishu that detoured Gamja's plans of making Yung & Xia the best. When Mishu was at the age of 13, Yung and Xia reached their age of 16. Mitsuri put the three in a handicap non-fatal match with Mishu at the bad end of the stick. Mitsuri had confidence in Mishu that even at his young age; his experience would win the sparring battle against his older opponents. Mitsuri was right. Even with the known secrets, Yung and Xia failed to win the battle against their sole enemy.
This devastated Gamja. He wanted victory and he wanted it so bad that he blessed his children with a skill-enhancing form of black magic. After his special ritual with his children, Yung and Xia, did not possess mythical and magical powers; instead their entire knowledge of ninjitsu was excelled and on their 20th birthday, they were immediately named 1st hierarchs. Through the years of their training, Gamja begged and pleaded Mitsuri for a rematch against Mishu, but each time, Mitsuri would deny Gamja's request knowing that his children were now possessed with the skill-enhancing black magic.
Since Yung & Xia did not have special powers like the other hierarchs, he wanted to make sure that his children would never fall victim to the corruption of the other hierarchs so he blessed them with the black magic of Immunity. Now his children would never fall victim to the power of Aisu's ice, Widow's web, or any other mythical means. If anyone wanted victory over the twins, they would have to use their pure skill to defeat the strongest hierarchs in the clan.
What makes Yung & Xia so strong, not including the fact of their black magic blessings, is how great they work together. Secluded from the rest, Gamja gave the two special training in hopes to be better than the rest. He taught them well in single fights, but he especially focused his training in team battle. He always taught them to count on each other at all time. Even when they are not in battle. Yung & Xia heaved the old man's great words. They heaved them to the point at the time they were 16, they began to fall in love with each other.
Their intimate love for each other is probably the only innocence found out of the two and it made them that much stronger. When in battle, they never fought in honor of the Black Spider Clan, nor for the protection of it. They always fought for the undying love they have for each other. At the age of 25, they had their first love child, whom which has been under great care by the Clan. Their son, Fei, is expected to be one of the greatest hierarchs of the Black Spider Clan within the years to come. In the meantime, he is cared for until he is old enough to begin his training.
