The episode 4 of season 2,starts with the end of episode 3,

A shroud of despair hung heavy over the once vibrant X City. Shattered glass glittered under the pale moonlight, echoing the city's broken spirit. Sho and his friends trudged through the desolate streets, their initial excitement dampened by the grim reality surrounding them.

"This place is totally devastated," Makoto gasped, her voice laced with worry.

"Where could everyone be?" Ayumo muttered, his gaze scanning the crumbling buildings.

Suddenly, a raspy voice boomed from the shadows, sending shivers down their spines.

"So you are the legendary rider Sho Yamato? Right?"

The group jumped back, eyes darting around to identify the source. The voice seemed to permeate the air, with no visible origin.

"Hey! Who's there?" Sho shouted, gripping his Flame Kaiser's handlebars.

A figure emerged from behind a pile of rubble, silhouetted against the moonlit sky. Clad in black, with glowing red eyes piercing through the darkness, the figure radiated an aura of menace.

"I am X," the figure spoke, his voice distorted like warped metal. "And I challenge you, Sho Yamato, to an Idaten Jump Battle. If you win, I will tell you everything that happened here."

A tense silence blanketed the ruins. This wasn't just any race; it was a gamble for answers, a desperate plea for knowledge amidst the crushing desolation.

"Alright, X," Sho declared, his eyes burning with determination. "I accept your challenge!"

The air crackled with anticipation as both riders took their positions. X mounted a sleek, black machine reminiscent of Gabu's Bloody Fang, its chrome glinting ominously.

"Fire up, Flame Kaiser!" Sho roared, channeling his fiery spirit into the bike. "Let's burn through this darkness!"

With a blinding flash, they were off, weaving through the broken cityscape like comets racing through the night. X proved to be a skilled opponent, his black machine effortlessly mirroring Sho's every move. They sped through shattered windows, leaped over collapsed bridges, and danced along crumbling rooftops, their Idaten powers clashing in a dazzling display of light and energy.

Sho fought with ferocity, fuelled by the need to know, the need to find his father, the need to bring hope back to this forsaken city. But X was relentless, his attacks precise and merciless.

Then, as they hurtled towards a towering, broken skyscraper, an opportunity arose. Sho utilized Flame Kaiser's agility, performing a death-defying corkscrew jump around the debris, leaving X momentarily in his wake. Seizing the chance, Sho unleashed his signature "Inferno Dive," a flaming meteor plummeting towards X from above.

Caught off guard, X barely managed to shield himself with a blast of dark energy. The collision created a shockwave that rippled through the city, rattling the few remaining windows and dislodging loose bricks.

As the dust settled, X lay sprawled on the ground, his black bike smoking and sparking.

"You... you win," X croaked, his voice strained. "But remember, this is not over. The darkness has come, and it will consume everything."

With a final rasp, X's body dissolved into a cloud of black smoke, leaving Sho and his friends standing amidst the devastation.

Hope flickered within them, a fragile flame ignited by the knowledge that X City still held survivors. But the echoes of X's words lingered, a chilling reminder of the darkness that lurked in the shadows.

Suddenly, a weak voice called out from within the fallen rubble of a nearby building.

"Sho? Help! I'm here!"

Sho's heart leaped. "Miss Uk?" he cried, rushing towards the sound.

He frantically clawed at the debris, revealing a battered but alive Miss Uk, the cheery mechanic who'd helped him during his previous visit.

"Sho! Thank goodness you're here!" Miss Uk coughed, her face streaked with dust and grime. "The city... it was attacked! A powerful force came from nowhere, shrouded in darkness, and they destroyed everything."

"Do you know where my father is?" Sho urged, his voice desperate.

Miss Uk's eyes widened. "Sho... your father... he's gone. He tried to defend the city, but they overwhelmed him. They took him... to the X Tower."

A cold grip of fear constricted Sho's heart. The X Tower, the towering symbol of X City, now loomed large in the distance, its broken peak scraping the night sky. It was a symbol of hope turned monument of despair, a beacon of darkness now pulsating with ominous energy.

With newfound resolve, Sho turned to his friends. "We have to find Dad," he declared, his voice ringing with unwavering determination. "We have to stop this darkness
