At midnight, the Puppet Clan, rulers of the world in the Dark Age of the future, travel back through a space-time passage to the past, the present.
Their magic, the “Soul-Imagining Mechanical Device,” allows them to turn their bodies into machines without needing any materials.
But every gain comes at a cost: they can no longer become true humans or have children.
The past, the present, is the age of Spirit Summoners, a special group of people who fight by summoning spirits. Spirits have their own abilities, which they can also share with their summoners.
But besides the Puppet Clan, this world is also threatened by countless Spirit Summoners and ordinary humans who act in their own interests.
As long as desire persists, the battles will never end.
As a Spirit Summoner who walks this world, “Ye” will let no enemy escape, nor will he lower his blade against those who deserve to die for the sake of some vainglorious, so-called greater good.
Even if the whole world is his enemy, he will fight to the death.
