Background
Ray Gransdori was born into Yesla family. He wasn't able to inherit the magic power from his parents, after that he was branded a failure and cast out. When Ray was 5 years old and all his family expected for him to die, a half-demon-half-spirit woman named Sheila took him to her home where she started to take care of him and became his adoptive mother.

After Sheila enrolled him in the biggest sword dojo of their city he quit after 3 days because he beat his master.

He started participating in different competitions but he hardly lost do to that he received the name of The Demonic Sword Saint and was recommended to the Demon King Academy.

In this time his adoptive mother began to suffer from spirit disease.

He keeps visiting her at the hospital and one day he tells her that she had to meet Anos and he was defeated by him.

History
2,000 years ago, General Jerga, Kanon's teacher, has a deep hatred towards the demons. After Demon King Anos's death, he wanted to set up the Hero Academy to pass his resentment to his descendants. Only Kanon thought that this idea was stupid. He was against the foundation of the Hero Academy until the end. He continued to sue, that Demon King of Tyranny wanted peace, he protected the demons because of the war and that's the same as humans. He claimed that the Demon King threw away his life to made the wall. However, not many people believed in it, even though Kanon is the Hero. They might think that Kanon was kind to the demons, so he wanted to give the reincarnated Demon King of Tyranny a chance to change his mind.

Kanon created the fictional demon king, Avos Dilhevia, for humans' revenge. He then talked, sometimes fought with the demons. Since the demons were admired Anos, they understood better than humans. In the end, everyone believed his words, and decided to forget Anos Voldigoad.

As expected, Anos's confidant, including Shin Reglia, can not forget his name. They reincarnated and moved away from Dilhaide. Even the mighty demons who were in conflict with him before the war promised that they would be quiet until he came back and everything was over.

Kanon fused his six roots with the Seven Elder Demon Emperors. It was their consent to erase everything. If Anos come in contact with the Seven Devil Emperor 2000 years later, he may notice the fusion. The Seven Elder Demon Emperor cannot lie to him, so they hoped to have their memory erased.

General Jerga abandoned his life and entrusted his feelings with resentment, hatred, and revenge against the demons in the magic . Kanon strongly opposed the magicalization of General Jerga. Although few in number, Kanon has some supporters. Perhaps General Jerga thought it could be a mess. Many people want their children and grandchildren to live without hatred. There was a gradual increase in the number of people, mainly those people, who agreed with Kanon. But in the end, they were on the side of General Jerga. With a gap, they killed Kanon.

With the remaining root left, Kanon reincarnated over and over again and gradually gained a body with deep blood from the demons. He became a pure-blooded demon.

2,000 years later, Ray used the Spirit God Human Sword to cut off the fate that Anos reincarnated as the Demon King of Tyranny.

After the school exchange with the Hero Academy, Ray planned to start a war between humans and the Demon King again, but this time, Ray appears as the reincarnated Demon King. Humans' hatred does not disappear, he believed that the struggle continues until either the Demon King of Tyranny or the human is destroyed. Therefore, he decided to be killed by humans, as the Demon King of Tyranny, Avos Dilhevia.
