Idaten Deities in the Peaceful Generation

Vicious and bloodthirsty demons who are immune to all manner of weaponry plague mankind; humanity's cries for help brings forth the Idaten; battle deities use their speed to hunt the demons down.

A look at what the Idaten have been doing in the eight hundred years of no demons to fight; Dr. Obami plots their defeat.

With the presence of the demons revealed to the surviving Idaten, Dr. Obami sends one of his strongest warriors to challenge the peace-softened deities.

Rin intends on wiping out the demons, but without a plan, some demons would easily escape; Ysley contacts another Idaten named Prontea to formulate a strategy, while the demons begin their own divide-and-conquer campaign against their divine enemies.

Three battles unfold simultaneously as Ysley takes on General Piscalat of the Zoble Empire, Paula and Hayato tangle with Cory, the demon who looks like a child soldier, and Prontea toys with the powerful Neput.

As Ysley and Prontea plot their attack on the demons, Dr. Obami has the eagle-eyed Miku continue to evaluate the threat posed by the Idaten.
