The Idaten Deities Know Only Peace

Centuries ago, vicious and bloodthirsty demons who were immune to all manner of weaponry plagued mankind. Humanitys cries for help brought forth the Idaten; battle deities who would use their incredible speed to hunt the demons down, and then seal them away. In the following 800 years of peace, the Idaten have not had any enemies to fight. But that is about to change...

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.

Three battles are unfolding 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. When the dust settles, how will the Idaten/demon conflict have changed?
