Heion Sedai no Idaten-tachi

Eight hundred years ago, terrifying demons threatened mankind's existence. On the brink of extinction, humans prayed to their gods, calling out for someone to save them. Emerging from these desperate pleas for salvation, battle deities known as the "Idaten" were born. Possessing unnatural strength and endurance, the Idaten managed to defeat the demons and an era of unprecedented peace was finally ushered in. Having never encountered demons before, the present generation of Idaten knows nothing of the demon's brutality, but they have instead only lived a peaceful existence. Training under Rin, the only remaining Idaten from 800 years ago, the new Idaten find ways to survive in a time where they have seemingly outlived their usefulness. However, when the tyrannical Zoble Empire resurrects a demon, the misfit crop of gods are called to the battlefield against their natural enemy once more. It has been 800 years since the battle gods Idaten, who boast overwhelming speed and strength, contained the demons who led the world to ruin after a fierce battle. That battle is now just an old tale in a distant myth. While the peaceful generation of the gods, who have never fought since they were born, are out of peace, someone has revived the demons from a long sleep! Bring armed forces, wisdom, politics, conspiracy, whatever you can use! No-rule & no-limit three-way battle royale is about to begin!!!
