Part 4: Deductions in the Dark
The faint, steady hum of the alloy wheelchair's motorized wheels echoed softly against the stone path as Haruto rolled out of the Academy's main entrance into the late afternoon sunlight.
He didn't touch the wheels. The sleek neural headset resting around his temples caught his silent thoughts, channeling a tiny thread of his Seiryū directly into the chair's motor to guide him forward smoothly.
Just past the main doors, Haruto brought the chair to a stop. The cool autumn air hit his pale face, but he barely felt it. He sat motionless, staring blankly down the wide path leading toward the front gates.
He didn't know where to go.
The thought of heading straight home filled his chest with a sudden, suffocating dread. Going home meant stepping into an empty house. It meant facing the silence where Ayame's voice should be. Through the headset, he mentally directed the chair to pivot toward the quiet side trail near the river, desperate to escape the reality waiting for him.
"Haruto?"
A familiar voice shattered the silence.
Haruto froze. Standing near the iron front gates was Akari, her coat pulled tight against the breeze. The moment her eyes landed on his bandaged frame, the neural headset across his forehead, and the motorized chair beneath him, her expression shifted into heartbroken shock.
Instinct took over. Haruto focused his mind, sending a sharp command through the headset. Powered by his Seiryū, the chair hummed to life, turning quickly to retreat down the Academy's outer wall.
"Haruto, wait!" Akari called out, her footsteps rushing across the stone path.
Faster, Haruto thought desperately, pushing his mental intent through the neural link. The motorized wheels sped up, but he couldn't outrun her. He didn't want to answer her questions. He didn't want to explain his injuries, and he couldn't bring himself to talk about Ayame or Kaito.
Akari covered the ground with long strides and stepped directly into his path.
To avoid crashing into her, Haruto instantly thought Stop. The Seiryū flow cut, and the chair locked its brakes inches from her feet. He kept his head lowered, his long crimson fringe completely hiding his eyes.
"Leave me alone, Akari..." he rasped, his voice hollow. "Just... go away."
Akari didn't raise her voice or ask about the headset. She looked down at his trembling, exhausted frame and saw right through the wall he was trying to build.
"We're going home, Haruto," she said softly, her voice filled with quiet authority.
"No," Haruto whispered. Through the headset, he sent a mental command to lock the wheels in place. "I'm not going back there."
"Haruto—"
"I said no!" he muttered, his voice cracking with desperation. "I don't want to go home!"
Akari looked at him for a long, heavy moment. She recognized the flight response of a child who couldn't face his own grief. Without arguing, she stepped behind the chair and reached for the manual push handles.
Haruto gritted his teeth, focusing every drop of his remaining Seiryū through the neural headset to keep the motor locked against her push. But the mental and physical exhaustion of the past twenty-four hours hit him all at once. His concentration shattered. The neural connection flickered and died, the Seiryū draining right out of the chair's power system.
With the motorized lock gone, Akari easily pushed the handles forward, rolling the heavy chair down the path.
Haruto didn't have the energy left to fight. His head sank into his chest as the wheelchair rolled smoothly beneath the shadow of the tall Academy gates. He turned his face away, staring silently at the ground as the school receded behind them, leaving him with nothing but the long road home.
The high afternoon sun cast short, stark shadows across the cobblestones as Akari continued pushing the alloy wheelchair down the winding village road. The silence between them was heavy, broken only by the steady, muted crunch of rubber wheels against gravel and the distant, somber sounds of a recovering village.
Behind the chair, Akari kept her hands firmly on the push handles, her eyes fixed on the back of Haruto's head. He remained completely rigid. His shoulders were locked tight, his chin pressed down against his collarbone, and his bandaged fingers twitched rhythmically in his lap. He looked less like a boy resting after a battle and more like someone being marched toward an execution.
After a long, suffocating stretch of road, Akari lowered her head slightly, her voice cutting gently through the quiet air.
"Haruto... why are you so afraid to go home?"
Haruto didn't answer right away. His bandaged hands tightened against his thighs, knuckles going white beneath the linen wraps. He stared straight ahead at the empty road stretching toward the Inazuma household, the silence stretching so long it seemed he might ignore her entirely.
Finally, his lips parted. His voice was a dry, barely audible whisper.
"Because... I'm afraid of Kaito."
Akari's footsteps faltered for a fraction of a second before she regained her rhythm. A flicker of genuine shock crossed her face. "Kaito? Haruto, why would you be afraid of your own brother?"
Haruto's head tilted down just a fraction lower. "Not Kaito..."
He paused, a dark, heavy shadow settling over his voice. "...The beast inside Kaito."
Akari froze in her tracks. Her grip on the handles tightened so hard the rubber groaned. The wheelchair came to an abrupt stop in the middle of the empty path.
Her breath caught in her throat. She knew Haruto had pieced together fragments about Ayame's condition during the raid—she had prepared herself for him to ask questions about her. But Kaito? No one had told him. No one had even hinted at it.
Akari stepped around to the side of the chair, her eyes searching his pale, shadowed face. "How do you know Kaito has a beast?"
Haruto didn't look up at her. His dull, bloodshot eyes remained fixed on the dirt beneath his wheels. He wasn't guessing randomly or spewing wild accusations born of panic. His voice was calm—scary calm—as he began methodically reconstructing the horror of yesterday's attack, cold analytical logic taking over where emotion threatened to shatter him.
"That Hunter hit me with the gauntlet," Haruto murmured softly. "I felt my ribs break. The impact... I couldn't stay standing. I fell immediately."
Akari remained silent, listening intently, her heart sinking with every word.
"Kaito got hit by the same thing," Haruto continued, his tone flat, like an investigator reciting evidence. "But Kaito didn't fall where I did. He was thrown backward. He hit the wall."
He lifted his right hand slightly, pointing a single, bandaged finger into the air to emphasize the anomaly.
"That should've hurt him more than it hurt me. I took the direct hit, but Kaito took the direct hit and the blunt force of the stone wall. His internal organs should have ruptured."
Haruto's expression darkened, his brow furrowing as the memory replayed behind his eyelids.
"When I reached him... when I checked his body... I knew what broken ribs felt like. I could feel mine screaming every time I breathed. But when I examined Kaito... I couldn't feel that same structural damage. His body was holding itself together."
Akari's pulse raced. "You're sure?"
"I'm sure," Haruto nodded slowly. Then, his voice dropped to a quiet, chilling frequency. "And I felt that exact same residual frequency with Ayame."
Akari's breath hitched. She realized with a rising sense of dread exactly where his brilliant, traumatized mind was leading him.
"Ayame had a beast inside her," Haruto said, the pieces locking into place with terrifying precision. "And Kaito felt the exact same way when I touched him. That's why I know."
He closed his eyes, drawing a slow, ragged breath. "It was the beast."
Standing beside him on the quiet road, Akari felt a cold chill run down her spine. Haruto hadn't seen the entity. He hadn't read a classified report or overheard the elders whispering in the dark. He had simply felt the physics of an attack, analyzed the physiological impossibility of Kaito's survival, cross-referenced it with Ayame's unique Seiryū signature, and solved the village's darkest secret in his head.
"The beast protected him," Haruto continued, his mind spiraling deeper into the dark logic. "Because if Kaito dies... the beast dies too. It needs his body to survive in this world."
Then, his voice cracked. The sharp, logical edge shattered, leaving behind a terrified eight-year-old boy staring into an abyss.
"But... Ayame's beast didn't save her," he whispered, his hands trembling violently in his lap. "It let her die. So why did Kaito's save him?"
The contradiction was eating him alive. The facts were right, but the terror was twisting them into something sinister. Kaito had survived. The monster inside him had shielded his body from total destruction. But Ayame was gone. And now, Kaito was waking up in the ICR, consumed by the unbearable guilt and grief of losing his sister.
"If Kaito loses control..." Haruto rasped, his breath coming in shallow, frantic hitches. "If the grief breaks him... what happens to the beast?"
"Haruto, stop," Akari interrupted firmly, stepping in front of the chair and dropping to one knee so she was eye-level with him. She reached out, gently cupping his cold, bandaged hands in her own. "Kaito is still Kaito."
Haruto shook his head vigorously, his crimson fringe swaying wildly. "You don't know that! You didn't feel it! Having that thing inside him... he isn't just my brother anymore!"
"Having a beast inside him does not automatically make him a monster, Haruto," Akari said, her tone absolute, refusing to let him descend into hatred or paranoia. "It doesn't strip away who he is."
Haruto didn't argue. He pulled his eyes away, staring down at her wrists. His fear wasn't rooted in malice toward his brother. He didn't hate Kaito. He was simply utterly terrified of the unknown—terrified of what a broken boy with a monster dormant in his chest might become when forced to face a home built on ghosts.
"Ayame is gone," Haruto whispered softly, the core of his panic finally laid bare. "Kaito lost her. He was already breaking before the raid... now he's completely hollow. What if the beast takes advantage of that emptiness? What if it uses his grief to take over?"
Akari looked at him, her heart aching at the immense weight resting on such small shoulders. He had solved the truth, but his fear had built a nightmare out of the answer.
"Then we'll deal with it together," Akari answered gently, her hands tightening around his. "You, me, and Kaito. We face it as a family."
Haruto looked up, his bloodshot eyes meeting hers. For the first time since she had caught him at the Academy gates, he realized she wasn't just trying to force him back into a building. She was standing as a shield between both brothers and the dark reality threatening to consume them.
"I don't know what he'll do..." Haruto admitted softly, his voice small and fragile. "I don't know who he's going to be when he wakes up."
"Then don't decide who Kaito is going to become before you've even looked him in the eye," Akari replied calmly. "Give your brother the chance to fight for himself."
Haruto went silent. He didn't smile, and he didn't pretend the terror in his chest had magically evaporated. He couldn't fully accept her optimism, but under the weight of her calm certainty, he couldn't prove her wrong either.
Akari slowly stood up, stepping back behind the alloy wheelchair. She disengaged the manual lock and began pushing the chair forward once more.
The silence returned, but the sharp, frantic edge of Haruto's panic had softened into a quiet, watchful stillness. Up ahead, past the bend in the stone road, the roof of the Inazuma household rose against the bright afternoon sky. It looked cold, dark, and terribly empty under the harsh midday sun.
Haruto stared at the front gate as it drew closer. He was still terrified of what lay inside. He was still terrified of the monster sleeping in his brother's chest, and the fragile, broken dynamic waiting to fracture them further.
But as the wheelchair rolled past the outer gate and up the stone walkway, Haruto kept his head up. He didn't ask Akari to stop, and he didn't tell her to turn around.
