The sea breeze howled as Kurata and Aoiro set foot on the island of Obaiburo. The island was unlike anything they'd seen before—a desolate rock with jagged cliffs and a towering structure resembling a fortress. This was the sacred land, home to the Rikuro—the five lords who held power since the beginning of time.
As the twins marched forward, they knew this mission was a dangerous gamble. Their father's words echoed in their minds. The goal was clear: confront the Rikuro and force an end to their tyrannical control. But the closer they got to the castle, the more soldiers flooded out, ready to stop them.
"Ready?" Aoiro asked, his blue lightning crackling at his fingertips.
Kurata nodded. "Always."
Suddenly, a barrage of bullets whistled through the air. The high-ranking soldiers of Obaiburo, armed with advanced weapons, fired at will. A storm of gunfire poured down on the twins, and in an instant, the bullets tore through their bodies. But instead of blood, only faint blue and black sparks flew out from their wounds. Lightning coursed through their skin, sealing the holes as if nothing had happened.
The soldiers stared in disbelief.
"They're monsters!" one shouted, retreating in fear.
But Kurata and Aoiro pressed forward, their powers growing stronger with each step. They moved like storms, swift and relentless. Kurata unleashed a torrent of black lightning, striking down soldiers one by one, while Aoiro's blue lightning danced like a storm, electrifying anyone in his path.
Still, the more soldiers they took down, the more emerged. The walls of the fortress seemed to come alive with enemies, overwhelming them with sheer numbers. For every victory, the assault grew more difficult.
"We can't take them all," Aoiro muttered, out of breath.
Kurata clenched his fists, black lightning arcing between his knuckles. "We don't need to. We just need to survive long enough to face the Rikuro."
But before they could advance further, a shadow loomed over them—Akatsuki, the Dark King, one of the most powerful enforcers of the Rikuro. His mere presence sent chills through the air. With a single swing of his massive blade, he sent a shockwave so strong that it knocked both brothers off their feet.
Kurata groaned as he struggled to rise. Aoiro's lightning flickered as he regained his stance.
"You're not leaving this island alive," Akatsuki growled, his eyes gleaming with the darkness.
