Smoke and sulfur assaulted the young man's nostrils as he jolted awake. His head throbbed with a dull ache. Disoriented, he blinked rapidly, trying to make sense of his surroundings. Gone was the familiar comfort of his study, with its towering bookshelves and the reassuring weight of ancient tomes. Instead, he found himself sprawled on a rocky outcropping, the ground beneath him pulsating with an otherworldly heat.
"What in the name of—" Shouma's words caught in his throat as he pushed himself up. His palms scraped against the rough stone.
A vast expanse of desolation stretched out before him, the horizon a blur of crimson and ash. Jagged obsidian spires jutted from the cracked earth, their surfaces reflecting the glow of rivers of molten rock that snaked through the barren terrain. In the distance, a mountain loomed, its peak obscured by rolling storm clouds that crackled with lightning.
His mind raced, desperately trying to reconcile the impossibility of his situation with the encyclopedic knowledge of mythology that had been his life's work.
"This can't be real," he muttered, his voice barely audible over the low rumble. 'It's the realm of Hades. But how?'
The last thing he remembered was poring over that strange diary. He filled its pages with accounts of mythological events described with a high level of detail. Now, he found himself thrust into a world he had only ever studied from the safe distance of academic inquiry.
A guttural roar shattered his thoughts, and he whirled around. His heart hammered against his ribcage. There, emerging from a fissure in the rock face, was a creature. Its body was that of a monstrous lion, but where its head should have been, three snarling canine visages gnashed and snapped.
"Cerberus." Shouma breathed with equal parts of terror and awe. The beast's eyes, six glowing embers of malevolence, locked onto him with predatory focus.
The full weight of his predicament crashed down upon him. This was no dream, no hallucination brought on by too many late nights of research.
Cerberus lunged forward, its massive paws gouging furrows in the stone as it charged. His body reacted on pure instinct, diving to the side as the creature's jaws snapped shut mere inches from where he had been standing.
"Wait!" He shouted, scrambling backward. "This isn't how it's supposed to go! In the myths, Heracles subdues you with his bare hands, or Orpheus lulls you to sleep with his lyre!"
The beast paused, cocking its heads in what almost seemed like confusion. He seized the moment, his mind racing through the countless versions of the myth he had cataloged over the years.
"You guard the gates of the underworld," he continued, his voice steadier now. "You're not just some mindless beast. You have a purpose, a duty."
One of Cerberus's heads growled low, while another tilted inquisitively. The third kept its gaze fixed on Shouma, unblinking.
Shouma slowly rose to his feet, his hands raised in a placating gesture. "I'm not here to challenge you or to steal from the realm of the dead. I'm not even sure why I'm here at all."
The creature took a step forward, and its massive form casted the man in shadow. He could feel the heat of its breath, smell the acrid stench of brimstone that clung to its fur.
"But I know your story," he said, "I know of your loyalty to Hades, of the heroes who have faced you, of the souls you've kept in check. You're more than just a monster in a tale. You're a guardian, a protector of cosmic order."
Cerberus's growls subsided, replaced by a low rumble that the man could feel reverberating in his chest. The creature's eyes, once filled with murderous intent, now regarded him with curiosity.
His mind raced. He was alive, for now, but what came next? The myths he had studied provided a script, a set path for the hero to follow. But standing here, face to face with a legend made flesh, he realized the profound limitations of those stories.
"I'm not Heracles," he said softly, more to himself than to the beast before him. "I'm not Orpheus or Psyche or any other hero who's stood where I'm standing now. I'm just Shouma Masaki. Just someone who studies myths."
Cerberus tilted their heads, as if considering his words. Then, to Shouma's astonishment, the creature took a step back and sat on its haunches, its tails sweeping across the scorched earth.
A choice lay before him, as clear as the forked path that now materialized in the desolate landscape. One road, well-worn and marked with the footsteps of legendary heroes, led towards a familiar narrative — challenges to be overcome, monsters to be slain, a predetermined destiny to fulfill. The other path was shrouded in mist, its destination unknown.
Shouma stood at the crossroads, the weight of mythological expectation pressing down upon him. Did he follow the well-trodden path of heroes past, using his knowledge to navigate the trials ahead? Or did he dare to forge his own way, risking the unknown but perhaps discovering a truth that lay beyond the bounds of ancient stories?
The choice, he realized, was his alone to make. And as Cerberus watched with its six burning eyes, Shouma took his first step towards an unwritten fate.
