Section 1: Transmigration and Awakening
Kaito Hayasaka's eyelids fluttered open to the intense brightness of morning sun spilling through a narrow classroom window. The air smelled of chalk dust and old wood—a mix that tugged faintly at memories he didn't think he had.
His head throbbed lightly, but more pressing was the strange, almost electric energy coursing through his body. He flexed his fingers experimentally, marveling at the strength and responsiveness of every tendon and muscle.
"Where… am I?" he muttered, his voice hoarse. The uniform folded neatly on the chair beside him looked foreign, yet somehow familiar. On the chest, the emblem of Seiran High Baseball Club glinted under the sun.
Memories flooded him—not of his previous life, but of another life: swings, pitches, running, catching, instincts honed to perfection. He felt the precise timing of every pitch, every hit, every movement… Ohtani.
"Yes… it's real," he whispered, a grin tugging at the corners of his lips. The realization struck him fully: he had all of Ohtani's physical abilities and baseball skills. Every pitch, every swing, every fielding motion was instinctive. He could feel the trajectory of a ball in his mind before it left the pitcher's hand.
Section 2: First Impressions of Seiran High
Stepping outside the classroom, Kaito was struck by the state of the school. Seiran High was small, low-ranked, and its baseball facilities were aged. The field was uneven, the nets torn, and the bleachers looked like they might collapse under the weight of an enthusiastic crowd.
Inside the gym, a group of players tossed a ball lazily. Some glanced at him with curiosity, others ignored him entirely. A middle-aged man with sharp eyes approached—Coach Nakamura.
"You're joining the baseball team?" he asked, neutral but wary. "Name?"
"Kaito Hayasaka," he replied, trying to mask the shock of his new reality.
The coach studied him closely. "Alright… show me what you've got."
Kaito nodded. He had no intention of revealing everything immediately. There were subtleties to master: integrating into a low-level team without disrupting the original storyline.
Section 3: First Practice – Pitching
The bullpen was quiet except for the occasional bounce of a ball. Kaito stepped up to the mound, feeling the dirt under his cleats. He stretched, testing the flexibility of his arm. Every fiber in his body responded perfectly.
He gripped the ball and wound up. The throw sliced through the air like a missile, hitting the catcher dead center. One by one, he struck out the batters—each pitch faster, sharper, and more precise than the last.
"Who… is this guy?" murmured a shortstop. His eyes widened as he caught the blazing fastballs.
Kaito didn't answer. His mind calculated spin, velocity, placement, and batter psychology in an instant. He wasn't just throwing a ball; he was controlling the flow of the game before it even began.
Section 4: First Practice – Batting
Next, Kaito grabbed a bat. The first swing sent the ball soaring into the far corner of the gym. The second cut through the air like a laser, bouncing off walls in perfect control. Every swing, every hit, was calculated yet fluid.
The team stared in awe. Coach Nakamura's jaw tightened; he hadn't seen talent like this in decades.
Kaito nodded faintly. He understood the danger of standing out too much. He would control his impact, training and guiding teammates without overshadowing them.
Section 5: Team Dynamics
Kaito spent the next days learning the team's rhythms. He noted personalities:
Riku Tanabe, a quiet, analytical infielder, had potential if he could control his nerves.
Shoji Kawai, a speedy outfielder, had talent but lacked discipline.
Akira Moriyama, the arrogant shortstop, believed natural ability was enough.
Kaito realized his role would be part mentor, part catalyst. Helping the weaker players improve, subtly, while keeping his full capabilities hidden was critical.
Section 6: Training Secrets
Every night, Kaito ran through invisible drills in his mind: perfecting his pitching mechanics, swing angles, base running, and fielding reflexes. He experimented with combinations of fastball, slider, and splitter pitches, visualizing batters from Seidou, Inashiro, and other schools.
He also analyzed his own stamina. Unlike ordinary players, he could recover faster, move with extreme agility, and sustain high intensity for longer periods. His mind constantly simulated game situations, predicting outcomes and refining reactions.
Section 7: First Scrimmage
Seiran High faced a neighboring school in a practice match. Kaito pitched first. Every throw was calculated: fastballs, sliders, and change-ups mixed perfectly. Batters swung at shadows, unable to read him.
At the plate, he hit line drives to gaps, foul balls with perfect control, and occasionally took pitches strategically. He wasn't showing full power—yet—but the results were clear: Seiran dominated.
Even more impressively, he moved in the field with instinctive precision. Grounders to second were scooped cleanly; line drives to the outfield were caught effortlessly. His speed allowed him to cover areas no ordinary player could, turning routine plays into remarkable outs.
The scoreboard reflected Seiran's dominance, but Kaito had restrained himself to avoid drawing excessive attention. He needed teammates to grow alongside him.
Section 8: First Team Bonding
After the scrimmage, Kaito sat with Riku and Shoji in the locker room.
"You're… something else," Riku said quietly.
"I'm just trying to help," Kaito replied, smiling faintly. Inside, he analyzed both boys: strengths, weaknesses, and mental state. He realized that guiding these players would be as important as his own skill display.
Moriyama, the arrogant shortstop, scowled from the corner. Kaito noted his pride; breaking it gently would be necessary to maintain team cohesion.
Section 9: School Life and Baseball Balance
Kaito's daily life became a delicate balance. He attended classes, interacted with teammates, and maintained the image of an ordinary student. Yet, every moment outside school was spent in baseball analysis, mental practice, and subtle physical training.
He began memorizing pitchers' tendencies from other schools, batters' weaknesses, and optimal defensive alignments. He was preparing not just for scrimmages but for the eventual tournaments where canon characters like Sawamura, Furuya, and Seidou would appear.
Section 10: Foreshadowing Canon Encounters
Even as he trained and integrated, Kaito foresaw encounters with canon players. He didn't want to overshadow their growth, but he wanted to influence matches subtly, nudging outcomes just enough to allow Seiran to improve while respecting the original story.
In his room, holding a baseball in his hand, Kaito whispered, "Tomorrow, the real test begins." He closed his eyes and visualized upcoming matches: pitches, swings, and fielding sequences already flowing in his mind like a symphony.
He was ready. The dual threat—the pitcher, hitter, and all-round baseball prodigy—had awakened.
Section 11: Closing Foreshadowing
Night fell over Seiran High. Kaito lay on his bed, body exhausted but mind alive. Every throw, every swing, every run had been replayed in his head. He had a mission: grow within this low-tier team, hone their skills, and leave an indelible mark without breaking the flow of the world he now inhabited.
This was just the beginning.
