Saurian Demon King

Background
After the destruction of his Community, Saurian Demon King wandered around Little Garden, often going off into recluse to meditate.

Appearance
Messy black hair that he likes to run his hand through when feeling awkward. An eyepatch covers his left eye. His muscles were well toned and maintained, according to KuroUsagi, though he wore clothes when she made that judgement. Most likely the clothes seen in the picture above. His smile is often said to make him seem suspicious due to the lack of sincere feelings in it.

Personality
Wistful about his past and living in regrets, he wanders around without aim and ambition. However, he is not arrogant about his power, and seems to see everyone else around him as young ones, which is true when compared to his age.

Relationships
Sakamaki Izayoi - Exchanged friendly blows while conversing, causing Kouryuu to realise that he was too trapped in his past.

Shiroyasha - acquaintances from before...

Volume 5
He was seeked out by Shiroyasha to be the replacement Floor Master of the East in Volume 5. He agreed after Izayoi's words and power made him realise that time should not continue to remain stagnant for him anymore.

Gift and Abilities

 * Divine Resistance - According to the nature of its essence and huge levels of spiritual powers,Saurian has a strong resistance to all forms of natural and supernatural influences.
 * Host Master - Demon Lord's right to form and to impose other beings created by himself,Gift Games, that is convert their spiritual and astral forces in the form of such tests,to stake player's own soul and their whole existence, thereby forcing the laws of the world and reality to obey the conditions of the Games. Even though he is not a Demon Lord Kouryuu still possesses this ability.
 * Immense Strength: Kouryuu possess a very powerful strength,as he blocked Izayoi's fist that could shatter mountains and open paths in the sea with a hand in volume 5 and he inflicted a fatal wound that aimed Izayoi's vitals with a strike that condensed of the earth and the sea. In volume 10, by using his club, his attack which aimed for the base of Azi Dahaka's head had the same power as a solar flare erupting from the surface of a star. The blow can even overwhelmed Izayoi if he was closing in, it produced shockwaves that created ripples in the atmosphere, his punch also packed the power to blow out a star in the skies and he sent Azi Dahaka's giant body flying into the sky with a roundhouse kick. The kick focused the energy enough to destroy a star in single point. His power is on par with the earth Godness's Gaia and a Sea God combined.
 * Immense Speed: During the fight with Izayoi,Kouryuu can keep up with Izayoi's speed which could leave his after-images, although that both sides didn't used their full potential.
 * Immense durabaility/stamina: By mediated in a Deep Sea Submarine Volcano for a thousand years, Kouryuu possess a body of steel, as seen when he withstood Izayoi's strike directly at the heart and he was completely unharmed.
 * Martial Expert: Though Kouryuu had the bad habit of collecting weapons, his actual strength lies within his transcendent bare handed martial arts. This was accomplished due to his training and his combat experience forged by many battles. If there was a decisive difference between Izayoi and Kouryuu, it was none other than the difference in experience.

Gift:

 * Manipulation of water - the ability to create, manage, and manipulate water. Saurian can create giant tsunamis that can flood the entire mountain chain. As seen in Volume 8, he is able to raise a curtain of water to cover an entire city with his gift.
 * Moon Dragon: Kouryuu concentrates his spiritual energy, create an impression that the moon is about to fall to the ground. At the same time, Kouryuu remove his eyepatch and revealing the artificial eye which resonates with the moon, then created a supergravity field releasing his true power which took the form of a huge sea dragon. In this form Kouryuu was able to restrain Azi Dahaka for a while with the help from Leticia so that Izayoi can stab Azi Dahaka's heart.
