"Hell Portal."
The moment Grey spoke, a massive rift tore open in the sky above the battlefield.
The portal was dark and ominous, swirling with infernal energy that crackled and sparked along its edges. Black lightning arced across its surface while crimson flames licked around its circumference, releasing an overwhelming pressure that made the air itself tremble.
Both the White and Yellow Devils froze in their tracks at the sight.
Moments later, devils began pouring through the massive rift by the hundreds. They descended upon the battlefield like a dark plague, their twisted forms trailing shadows and corruption behind them as the air itself seemed to darken wherever they passed.
"More devils?!" the Yellow Devil King roared from across the settlement. "Where did they come from?!"
His generals looked equally stunned by the sudden development.
"T-These devils..." one of them muttered in disbelief. "They are all at the 12th Rank?"
"WHAT?!"
"HOW IS THAT POSSIBLE?!"
