Besides the Human Realm where we live, there are five other worlds in different dimensions: the Celestial Realm, the Asura Realm, the Spirit Beast Realm, the Hungry Ghost Realm, and Hell. Each world once had its own boundaries and order, but every ten thousand years, the spatial barriers between the Six Realms disappear. Until the barriers form again, creatures from all six realms can travel between them.
Ten thousand years ago, the Asura King of the Asura Realm slew the demons of the Demon Realm and saved all living beings. After reincarnating, he learned that in his previous life, he had been saved by a demon he had regarded as an ant and sworn enemy. Having finally understood the consequences of good and evil, he resolved to stop killing.
Ten thousand years later, the Asura King has reincarnated as an ordinary university student in the Human Realm. With the demons of Hell about to descend once more, will he choose to awaken and take up his blade again?
By chance, the Asura King rescues the Ice Witch, the demon who killed him in his previous life, from ten thousand years of frozen slumber. The Ice Witch has lost her memories and become a child, treating the Asura King who rescued her as family. How will he choose to face this demoness, who could regain her memories at any moment?
From forcing psychics into duels to the death for profit to harvesting the source of life from the Asura Realm in a headless-man factory, all these evil deeds point to one human organization: the Heavenly Eye Society!
Perhaps even more hideous and terrifying than the demons of Hell are the humans of the Human Realm...
