Kaito drifted in darkness, but it was not the cold, empty void of the system’s domain. This time, warmth surrounded him, the scent of chalk dust and freshly polished wood filling his senses. Faint murmurs echoed around him, growing clearer with each passing second.


    The moment he opened his eyes, he was not in Eldoria.


    He was back.


    Rows of desks stretched before him, a blackboard at the front of the room covered in faint remnants of past lessons. The late afternoon sunlight streamed through the windows, casting a golden glow over the quiet classroom. Students moved about, gathering their belongings, chatting about their plans after school.


    Kaito Arata was a teacher once more.


    His chest tightened as reality settled in. Was this real? Had everything in Eldoria been just a dream? The battles, the blood, the overwhelming pain—had it all been some elaborate illusion?


    "Sensei?" A voice broke through his thoughts.


    He turned to find a student standing beside his desk. Takahashi, one of his most dedicated students, clutched a bamboo practice sword. "Are we still on for kendo practice today?"


    Kaito blinked. Kendo practice.


    His mind felt sluggish, torn between the memories of Eldoria and the familiarity of the world around him. He had always stayed after school to train students, sharing his love for the art of swordsmanship alongside his lessons in mathematics. It had been a fulfilling life, one filled with purpose.


    "Yeah," he found himself saying, his voice steady despite the turmoil inside. "I''ll meet you at the dojo in a few minutes."


    Takahashi grinned, bowing slightly before dashing out of the room, leaving Kaito in stunned silence.


    His fingers curled against the surface of his desk. If this was truly real, then what had he experienced? Had he imagined everything? Or was this another illusion?


    <hr>


    Minutes later, he stood in the school dojo, dressed in his kendo uniform. The rhythmic clash of bamboo swords echoed as his students warmed up. He moved through them, offering corrections, guiding their footwork and posture. Yet something felt different.


    He knew these drills, these students, and the way they moved, but there was a sense of detachment. His reactions were sharper, his movements refined. It was as if his body had mastered something far beyond simple kendo forms.


    "Sensei," Takahashi called out, holding up his shinai. "A match?"If you find this story on Amazon, be aware that it has been stolen. Please report the infringement.


    Kaito hesitated before nodding. The students gathered around, anticipation clear in their eyes.


    The match began.


    Takahashi struck first, but Kaito parried with ease. Another attack came, but he sidestepped effortlessly. Each movement felt unnaturally smooth, his strikes faster than he remembered.


    Takahashi faltered, sweat beading his forehead. "Sensei... when did you get this fast?"


    Kaito did not have an answer. He was fighting on reflex, his body responding in ways that felt almost unnatural.


    The match ended swiftly. Though he had held back, the difference in skill was undeniable. The students exchanged glances of awe, whispering among themselves.


    <hr>


    After practice, Kaito changed back into his regular clothes and left the school grounds, walking through the familiar streets of his city. Neon signs flickered, the scent of fresh takoyaki drifted from a nearby food stand, and the chatter of students filled the sidewalks.


    Despite the familiarity, something felt distant.


    He had arranged to meet an old friend at a café, a former colleague who had moved to a different school but still kept in touch. The conversation had been light, filled with nostalgic reminiscing about their students and the pressures of teaching. His friend had joked about how Kaito still worked too hard, still stayed late at school, still dedicated himself fully to his students. Kaito had laughed, yet the feeling of disconnect remained, lingering beneath the surface like an itch he could not scratch.


    As he was leaving the café, he reached for the door but stopped when a familiar voice called out.


    "Kaito-sensei?"


    Turning, he saw Fujihara-sensei, a senior teacher from his school, standing near the counter. She gave him a polite smile before glancing outside.


    "It’s started pouring pretty hard. You should wait a bit before heading out," she said, adjusting her glasses. "I’ll treat you to a cup of coffee while we wait."


    Kaito hesitated, glancing out the window where the rain had indeed grown heavier, tapping against the glass in steady sheets. The warm scent of coffee drifted through the air, inviting and familiar.


    But something inside him urged him to decline.


    "Thank you, Fujihara-sensei, but I should get going. I still need to grab dinner before heading home," he replied with a polite bow.


    She gave him a knowing look but nodded. "Alright, but be careful. The roads can be dangerous in weather like this."


    Kaito thanked her again before stepping out into the rain.


    <hr>


    The shortcut through the alleyway was one he had taken countless times before. The pavement was slick beneath his shoes, and the distant hum of traffic was the only sound accompanying his footsteps.


    Headlights flashed from the corner of his vision.


    A truck barreled down the narrow street, its tires skidding against the wet ground.


    Kaito’s instincts screamed at him to move, but his body failed to react in time.


    Years of kendo training, coupled with the reflexes that still lingered from his dream, kicked in, but it was not enough.


    The impact came.


    Pain exploded through his body as he was thrown onto the asphalt. His vision blurred, the cold rain mixing with the warmth of his blood seeping into the street. Distantly, he heard people shouting, footsteps rushing toward him.


    His chest heaved, breath shallow. Darkness crept in at the edges of his vision. But as he stared up at the night sky, a strange sense of peace washed over him.


    If this was the end, then maybe that other world had been more than just a dream.


    Everything faded to black.


    <hr>


    A deep, resonant voice echoed in his mind.


    <hr>


    [Evolution Progress: 40%.]


    <hr>


    Memories surged forth. The Direfang Alpha. The Direwolf Scouts. The Behemoth. The system. Eldoria.


    He had died.


    He had been reborn.


    And now, he was evolving.


    As thoughts of the past and present swirled within his mind, Kaito drifted back into slumber.


    His evolution continued.
