Isaku Honjo is a cold-blooded prosecutor who won't hesitate to fabricate evidence to ensure a criminal's conviction.
One day, a tragic accident claims his life along with his wife and daughter, and he finds himself descending into Hell.
It is there that the devils are hosting an event known as the "Millennium Festival."
The devil Bune sets his sights on Isaku to participate as his "Devil's Proxy" and offers him a deal.
If he joins the Millennium Festival and claims the legendary Solomon's Ring, any wish can be made a reality.
He is promised that not only he, but his entire family can be brought back to life.
Entering into the contract, Isaku throws himself into the festival as Bune's proxy, wielding the sword of judgment against the denizens of Hell.
Will he truly be able to lay claim to Solomon's Ring?
A once-shrewd prosecutor now delivers judgment to devils in this ultimate dark fantasy.
