Esper Harem in the Apocalypse

Eric's penchant for chaos was evident as he conjured a swirling vortex of water and fire. The torrent raged through the sky, engulfing multiple creatures in its tempestuous grip. Erika continued her relentless assault, her blade striking with precision and grace, decimating the monstrous forces with each blow.

As the dust began to settle, the battlefield had undergone a transformation. The fallen monsters lay scattered like grotesque statues in a nightmarish garden of destruction. Erika and Eric hovered in the air, victorious and unscathed, while the S-rank heroes on the ground couldn't help but applaud the indomitable siblings. It was a display of heroism and power that would be etched into the annals of history.

As Eric and Erika weaved through the sky, dismantling the monstrous threat before them with unparalleled precision and grace, the strongest S-rank hero, his body battered and injured from the brutal battle with the monsters, lay on the ground, gazing up at the awe-inspiring spectacle before him. His eyes were filled with shock and an overwhelming sense of awe. Over the years, he had seen and met countless strong heroes and faced formidable monsters, but what Eric and Erika displayed was something beyond his wildest expectations. Despite the pain that coursed through his body, he couldn't tear his eyes away from the duo. The sheer power they exuded, the precision of their attacks, and their unwavering resolve to protect the city left him in a state of both disbelief and admiration.

His eyes tracked their every move, his awe and respect growing with each passing moment. The ferocity, the synchronization, and the sheer magnitude of their abilities left him in a state of shock.

He had heard tales of these legendary twins and had even witnessed their feats from afar or through screens, but nothing could have prepared him for the reality of seeing them in action. In that moment, it became clear to him.

He whispered to himself, "The difference between an S-rank hero and an SSS-rank hero is unimaginable, but this... this is something else entirely. It's as if they exist in a league of their own."

His body ached, and his wounds throbbed with pain, but he couldn't tear his eyes away from the awe-inspiring display of power and skill before him. Eric's overwhelming strength and Erika's masterful swordplay were like nothing he had ever seen.

"The stories, the legends, they pale in comparison to reality," he muttered, a wry smile on his bloodied lips. "Calling the twins SSS-rank heroes would be an insult to them. They transcend such titles. Their strength defies description."

The strongest S-rank hero chuckled, the sound mixed with the pain of his injuries. "Having them at our side is more than a blessing; it's a miracle. We're beyond lucky to have them fighting on our side."

As the battle raged on, the injured hero found renewed determination, knowing that Eric and Erika, the world's strongest heroes, were with them. In the midst of chaos and destruction, their power shone like a beacon of hope, and he vowed to stand by their side, no matter the odds.

As the remnants of monstrous foes lay scattered around them, Eric and Erika walked with purpose towards the group of injured S-rank heroes. Their presence alone was enough to inspire both awe and a profound sense of inadequacy among the S-rank heroes. The leader of the S-rank hero team, who had watched Eric and Erika's astounding display, felt a deep sense of shame at calling himself S-rank in their presence.

Even as they approached, an unexpected threat emerged. The massive head of one of the defeated monsters, which the twins had skillfully cleaved from its body, unleashed a devastating lava beam from behind, aimed directly at Eric and Erika. The S-rank leader, alarmed by this sudden danger, attempted to shout a warning, but before he could utter a single word, Erika reacted with astonishing speed and precision.

In an instant, with impeccable precision, she sliced the monster's head to pieces, her blade moving at a speed that defied comprehension. Without even looking back, she had eliminated the threat.

The S-rank leader was left in utter disbelief. He mumbled to himself, "Her movements... they're faster than humanly possible. She was faster than my thoughts could even form."

With the danger averted, Eric and Erika reached the injured heroes and helped them to their feet. They immediately called for medical assistance, making sure the injured heroes received the care they needed.

With the S-rank heroes now in medical care, Eric and Erika remained at the epicenter of the battleground, their eyes transfixed on the colossal screen that had mysteriously manifested in the sky 72 hours prior to the apocalypse. This monumental screen had become a guidebook for every living being, offering insight, strength, and hope when all seemed lost.

As the sun dipped below the horizon, casting a blood-red hue over the war-torn city, Eric and Erika made their solemn proclamation. With unwavering conviction, they looked up at the massive screen that loomed like an omnipotent judge over their battered world.

17:46

"With this..." Eric declared, his voice resonating with both determination and responsibility, "We have become the strongest heroes in the world."

Their assertion wasn't a mere boast; it was a testament to their indomitable spirit and their commitment to protecting their world against impossible odds. The colossal screen, which had appeared as an enigmatic ranking system for heroes from all corners of the globe, confirmed their declaration.

The screen altered in real-time, its vibrant hues shimmering to life. In a grand display visible to every survivor, a change occurred. Eric and Erika's names, once among many, rose to the pinnacle, shining brightly as beacons of hope in the ever-darkening world.

On that fateful day, bathed in the eerie glow of the colossal screen, Eric and Erika achieved a distinction beyond titles and recognition. They became, by the world's own acknowledgment, "Humanity's Strongest Heroes." This wasn't a designation granted by any individual or government; it was a declaration made by the world itself, a symbol of their unwavering dedication and their enduring strength in the face of global calamity.

"Ah… I suddenly feel like drinking chicken soup…" Eric muttered.

"Steak for me…"

And so, the siblings flew away to the closest restaurant they could find to sate their hunger.
