The Corinthian

It was centuries and centuries since Corinthian remembered when it all began, Lords Morpheus had created Corinthian to be a nightmare that revealed the greatest fear of humans, but Morpheus also created Akiratsune, or Akira, who is a dream and can reveal the greatest desire of humans.
Corinthian and Akiratsune are opposites, according to the words of Morpheus himself "one cannot coexist without the other", Corinthian from the first time he laid eyes on Akiratsune, Corinthian was enchanted, Akira had a humanoid appearance like Corinthian, but Akira had nine tails of dark fur of a fox, as the centuries passed, Corinthian found himself extremely in love with Akira, but Lords Morpheus always left Akira and Corinthian apart, according to him "a dream and a nightmare cannot have a relationship".
After a while, Morpheus disappeared from the dreaming realm, and all the dreams and nightmares left the realm and went to the waking world, Corinthian saw this as an opportunity, but Akiratsune had already left the dreaming realm first before Corinthian could reach him, after about 106 years, Corinthian remained in the waking world, but he still wanted to have Akira, according to Corinthian's mind because they are basically opposite beings and cannot live without each other, Corinthian had to have Akiratsune as his spouse, his beloved and only his.
