Nakago

Nakago (real name Ayuru Gi) is the main antagonist of the anime and manga series, Fushigi Yuugi.

He is the unofficial leader of the Seiryu Seven and is not only the most powerful of the Seiryu Warrios, but he is the most powerful Celestial Warrior, besting even Tamahome's skills with great ease. He is capable of energy blasts, enhanced speed, and is an accomplished sorcerer. He is heavily charismatic and is why Yui Hongo thought that Miaka Yuki and her were no longer friends.

At first, Nakago wanted to take over the entire Universe of the Four Gods and even betrayed the Kutou Emperor, killing him. However, he saw the illusion Tomo made from Miaka's memories and sought to conquer the real world.

He planned to use Yui's status as the Priestess of Seiryu in order to gain immortality. His plan failed when Yui uses her final wish to undo the seal on Suzaku. Nakago is only defeated when Miaka seals Seiryu's power, making Nakago powerless and vulnerable to Tamahome. Nakago accepts his fate and is killed when Tamahome punches a hole through his chest. Before Nakago dies, Tamahome is able to see Nakago's tragic past. When Nakago was a child, his people were invaded by Kutou and his powers manifested and he accidentally killed his mother.
