—Demons who hate humans, and humans who hate demons.
About
The Taisho Era.
In the shadows of an era where civilization was shifting, a secret struggle between humans and demons continued.
Demons, who were once human, have had their loved ones taken by humans and attack people out of hatred. Meanwhile, demon hunters have had their loved ones taken by demons and swing their blades for revenge.
Both have lost those they love, both hate each other, and both call the other evil.
Is what lies there justice? Or is it merely hatred?
Is the demon evil, or is the human evil?
This is a story where hatred and justice intersect.
And which side will you stand on?
