Emerging from the **Frozen Wasteland**, the trio stepped into the **Storm Realm**, where dark clouds swirled overhead, crackling with energy. Thunder rumbled ominously, and lightning streaked across the sky, illuminating the landscape in brief flashes.
"Stay alert," Kento warned, feeling the tension in the air. "We're not alone."
Suddenly, the **Thunder King** descended from the clouds, a towering figure cloaked in storm clouds. "Foolish mortals! You dare challenge me?" he roared, his voice booming like thunder.
Kento stepped forward, holding his sword defiantly. "We're here to stop your tyranny!"
The Thunder King summoned a storm, hurling bolts of lightning down at them. Kento and Rena barely dodged the strikes, the ground exploding around them.
"We need to split up!" Kento shouted, hoping to confuse their opponent.
Rena nodded, her eyes focused. "I'll distract him with light magic while you flank him from the side!"
"Liru, can you absorb the lightning?" Kento asked, dodging another bolt.
"I'll try! Just keep him busy!" Liru replied, transforming into a shield-like form to absorb the energy.
As Rena unleashed beams of light, the Thunder King roared in anger, striking back with furious bolts of electricity. Kento seized the moment, darting to the side and striking at the Thunder King's exposed flank.
"Now, Rena!" Kento shouted, creating an opening for her to attack.
Rena summoned a massive blast of light that collided with the Thunder King, forcing him to stagger back. "Keep going!" she urged, rallying her strength.
The Thunder King, furious, unleashed a powerful storm, causing winds to whip around them. "You think you can defeat me? Feel the power of the storm!"
Kento and Rena braced themselves against the winds as Liru absorbed more lightning, its form shimmering with energy. "We can't let him overwhelm us!" Kento yelled.
"Together!" Rena cried, raising her hands to channel her magic.
Kento charged forward, using the **Blade of Seven Killers** to strike at the Thunder King, while Rena's magic intensified the attack, amplifying its power. The combined force struck true, and the Thunder King screamed as he was engulfed in light and energy, exploding into a shower of sparks.
Panting, Kento, Rena, and Liru stood together, weary but victorious. "Four down," Kento said, his resolve strengthening. They continued to the next gate, knowing that greater challenges awaited them.
