Rebellion? Then die-all of you!

At the northernmost edge of the Underworld, on the border of Gremory Territory.

The pitch-black mountains rolled endlessly, like sleeping colossal beasts.

The violent deathly aura of the Devils churned madly across the sky.

The armies of the Old Maou Faction and the stubborn Devil nobility numbered in the hundreds of thousands.

At this moment.

They had completely surrounded the entire border defense line, leaving not even a gap.

One giant void warship after another, forged from pitch-black magic-guiding metal.

They blotted out the sky and sun, stretching across the dark-red sky.

The warships radiated a cold, oppressive black light.

"Execute the human usurper!"

"Take back the Underworld's dominion that belongs to us Devils!"

"That black-haired human is nothing but an arrogant thief!"

The high-pitched, savage roars blended together across the border.

The Devil soldiers frantically waved their magic swords.

Their momentum was extraordinarily overbearing, and their voices thundered without end.

"The Gremory Family actually grovels before humans!"

"They aren't worthy of being noble Devils at all!"

The leading general of the Old Maou Faction stood aboard the most majestic warship.

Pointing ahead with a hideously twisted expression, he shouted:

"Trample Gremory Castle!"

"Use that black-haired human's blood to consecrate our battle flag!"

"Kill! Kill! Kill!"

The army of three hundred thousand roared at once.

The waves of sound shook the surrounding void until it shattered inch by inch.

"General, is that fellow really that terrifying?"

An adjutant stepped forward and asked somewhat nervously.

"What is there to fear?"

The general sneered, his face full of disdain.

"We have three hundred thousand elite soldiers and more than ten thousand magic-guided warships!"

"Even if we bury him beneath sheer numbers, we can crush him completely!"

"Humans are nothing more than feeble crawling insects!"

He shouted arrogantly, his tone brimming with conceit.
