Seiryū

Seiryū (青龍, Seiryū), more commonly known as Azure Dragon of the East (東方青龍, Tōhō Seiryū), is parts of the legendary Five Symbols in Rōran. He serves as the hidden guardian of Eastern Rōran ever since he was born.

Appearance
Seiryū is a azure colored dragon with appearance similar to the eastern dragon mythology; four limbs, sharp teeth and wingless. Both the front limbs are bigger than the back and each limb has five claws. It has a pair of malicious and cold cyan eyes, with a black eye markings surrounded. Apart from that, he has a very long cyan hair, a bizarre appearance compares to what depicted in the ancient mythology about dragons from all around the world.

While in the Human Form, he retained most of the facial appearance such as hair, teeth and eyes from his true form, only scaling them to the size of human. His limbs turns similar into the human hands and legs while his sharp claws are remained. Since the evolution of human attire, he begins to wear white jacket and hakama whenever he descends to the human world.

Background
Seiryū is born along with his siblings to the world by an unknown power that is far superior than the Sage of the Six Path. Despite being a mythical creature, he was first born in the human form in Rōran without any knowledge about his identity, just like an innocent young birth baby. Due to their immense chakra that serves as food supply, he grew up happily without any problem.

When Seiryū first came to sense at the age of six, he along with his siblings found their true purpose of living from a tablet in the center of the Rōran. It was left by their creator that recorded their respective hidden power, identity and various information. Seiryū found that his source of power and life was maintained by the Eastern Ryūmyaku, thus the region must be protected by all cost. Seiryū also realized that they possessed a seal that forbade them from revealing any information about themselves to the outsider. Since then, Seiryū became the guardian of the Eastern Rōran, observing the whole history of Rōran; from human first came to Rōran to being listed as criminal zone.
