His real name is Sukuna, is a Dragon Lord of the sea, who has been waiting to seek revenge against Tomoe for 526 years and 28 days at 2 o'clock 18 minutes and 4 seconds in the morning for ripping out his right eye and attacking the north gate of Ryuusuu Castle. He found Tomoe after he saved a girl from drowning in the sea. The Dragon Lord's eyes are known as the Longevity Elixer and are said to give great power to whoever has drank them.
