The Monster Returns Home

The house was dark when Yui Kodai arrived, the porch light flickering weakly as if afraid to fully illuminate her path. The air was heavy with silence, thick and stifling, broken only by the soft creak of the door as she stepped inside. The faint scent of lavender lingered in the hallway—Sakura Kodai's favorite air freshener—but tonight, it felt cloying, suffocating, a weak attempt to mask the tension that always seemed to hang in this house.

"Mom, I'm home," Yui called out, her voice sharp and deliberate. She dropped her bag by the door, its weight thudding against the hardwood floor. There was no response, only the faint sound of footsteps upstairs.

Yui's lips curled into a thin smile. Of course she's waiting for me.

She moved through the house with measured steps, the dim glow of the kitchen light casting long, distorted shadows on the walls. The familiar surroundings felt alien now, each creak of the floorboards echoing unnaturally loud in the oppressive quiet. When she reached the living room, she stopped. Her eyes drifted to the mantle, where a framed photo of the family stared back at her.

Momo's smile was radiant, her perfect posture and gleaming eyes screaming success. Sakura stood beside her, her hand resting proudly on Momo's shoulder, while Mangetsu smiled faintly, almost as though he was an afterthought. And then there was Yui, standing off to the side, her expression subdued, her presence overshadowed by the brilliance of her cousin.

Yui stared at the photo for a long moment before scoffing. Not anymore.

The Confrontation

Sakura Kodai descended the stairs as Yui entered the kitchen, her footsteps soft but deliberate. Her mother's face was drawn, her eyes calculating as they landed on her daughter. For a brief moment, there was silence between them, a chasm of unspoken words stretching wider with every passing second.

"You're late," Sakura said finally, her voice clipped and icy.

"Had things to do," Yui replied, her tone casual but laced with venom. She poured herself a glass of water, her movements slow and deliberate. "Like dominating the quirk apprehension test. Did you hear? Highest score in the class. Even higher than Momo."

Sakura's lips thinned, her hands tightening into fists at her sides. She didn't respond immediately, her gaze cold and scrutinizing.

"What's wrong?" Yui asked, her tone turning mocking. She leaned against the counter, her sharp eyes locking onto her mother's. "Aren't you going to say you're proud of me?"

Sakura's silence stretched on, heavy and suffocating. Finally, she spoke, her words cutting like a blade. "You must have cheated."

Yui blinked, her smile faltering. "What?"

"There's no way you surpassed Momo," Sakura said, her voice gaining strength, her tone firm and unyielding. "You've never come close to her in anything. Not once. And now you expect me to believe you suddenly excelled beyond her?"

The words hung in the air like a poison, seeping into every corner of the room. Yui's grip tightened around the glass in her hand, her knuckles turning white.

"I don't believe it," Sakura continued, her voice rising. "You're not capable of this, Yui. I'm calling UA and telling them I suspect you've been using Trigger."

The mention of the drug hit Yui like a slap, her head snapping toward her mother with a look of pure venom. "Trigger?" she repeated, her voice low and dangerous. "You think I'd resort to that? A poor man's recipe? Don't insult me."

"I'm not insulting you," Sakura shot back, her hand moving toward her phone on the counter. "I'm protecting your future. If you're caught—"

"If I'm caught?" Yui interrupted, her voice rising. She stepped closer, her presence suddenly suffocating. "The fact that I excelled is so unbelievable to you that your first thought is drugs? Not that I've worked harder than anyone else, not that I've surpassed your golden girl—no, it's drugs." Her voice dripped with sarcasm and venom. "You're unbelievable."

Sakura's hand closed around her phone, but before she could lift it, Yui grabbed her wrist. Her grip was like iron, unrelenting, and Sakura winced, her eyes widening with fear.

"If you make that call," Yui said, her voice dropping to a chilling whisper, "it'll be the last one you ever make."

A Mother's Plea

Sakura's breath hitched, her eyes darting between Yui's cold stare and her immobilized wrist. "Yui," she said, her voice trembling. "Don't do this. I'm your mother."

"No," Yui said, her lips curling into a cruel smile. "You haven't been my mother for a long time."

She released Sakura's wrist abruptly, only to drive her fist into her mother's stomach. Sakura gasped, doubling over as the air was forced from her lungs. She tried to straighten, but Yui was on her again, grabbing her by the collar and forcing her against the counter.

"You're going to listen to me now," Yui hissed, her face inches from her mother's. "From now on, you'll obey me. No more phone calls, no more accusations, no more trying to ruin what I've worked for. If you even think about snitching to Father, it's over for you. Do you understand?"

Sakura's eyes filled with tears, her voice trembling as she whispered, "You'll never be a hero."

Yui froze for a moment, her eyes narrowing. The air in the room seemed to drop several degrees, the tension thick enough to choke on.

"You're a villain," Sakura said, her voice barely above a whisper.

Yui's grip tightened, her knuckles turning white. Her breath came in sharp, shallow bursts, her body trembling with barely restrained rage. "Say that again," she whispered, her voice shaking.

"You're a villain," Sakura repeated, louder this time. "You always have been."

The words shattered the fragile control Yui had been holding onto. With a snarl, she shoved Sakura away, her strength sending the older woman sprawling backward. Sakura's foot caught on the edge of the step, and she tumbled down the stairs, her body hitting the wooden steps with a sickening series of thuds.

When she finally came to a stop at the bottom, she was silent. Still.

Unmoving.

The Aftermath

The room was eerily quiet, the faint hum of the refrigerator the only sound breaking the stillness. Yui stood at the top of the stairs, her chest heaving, her hands trembling at her sides. She stared down at her mother's motionless form, her sharp eyes scanning for any sign of life.

Sakura didn't move.

The realization hit Yui like a cold wave, but she didn't flinch. She didn't cry, didn't gasp, didn't even blink. Instead, she straightened, brushing her hair back with a steady hand. Her expression was unreadable, her face a mask of calm.

She turned away from the stairs, her movements slow and deliberate as she grabbed a glass of water from the counter. She took a sip, the cool liquid soothing the burn in her throat.

When she finally spoke, her voice was quiet, almost contemplative.

"You should've just been proud."

And with that, she walked upstairs to her room, leaving the silence—and her mother—behind.

The Hospital Visit

The Yaoyorozu family arrived at the hospital just as the sun dipped below the horizon, painting the sky in hues of fiery orange and violet. The fluorescent lights inside the hospital felt harsh and cold, the sterile white walls devoid of any comfort. Hisashi Yaoyorozu walked ahead, his footsteps deliberate, his sharp eyes scanning every detail. Behind him, Momo and Yuna followed quietly, their expressions etched with worry.

They were directed to a private room on the fourth floor, where Sakura Kodai lay unconscious, her face pale against the stark white sheets. Mangetsu Kodai stood at the bedside, his broad shoulders slumped as he stared down at his wife. His usual air of quiet strength was absent, replaced by a heavy stillness that made the room feel smaller.

Yui was sitting in a chair by the window, her posture calm and composed. She looked up as the Yaoyorozus entered, her face a mask of quiet sorrow. Her hands were folded neatly in her lap, but her sharp eyes flicked to each family member, lingering briefly on Hisashi before returning to the floor.

"Thank you for coming," Mangetsu said, his voice low and strained. He glanced at Yui, his expression softening. "Yui's been here all day."

"What happened?" Hisashi asked, his tone calm but firm, his gaze settling on Yui.

Yui hesitated for a moment, her face twisting into an expression of guilt and sadness. She clasped her hands tighter, her knuckles whitening as she looked down.

"It was an accident," she said, her voice trembling just enough to sound convincing. "We… we were arguing. Nothing serious, just the usual disagreements. She was upset and turned to leave, but she tripped on the top step. I tried to catch her, but it all happened so fast…"

Her voice broke slightly, and she looked up at Hisashi with wide, tear-filled eyes. "I—I feel so horrible. If I'd been faster, I could've stopped her."

Momo's heart twisted at the sight of her cousin's tears. She stepped forward, placing a comforting hand on Yui's shoulder. "It's not your fault, Yui," she said gently. "Accidents happen."

Yui nodded, her lip trembling as she leaned into Momo's touch. "I just wish I could've done something," she whispered.

Yuna sighed, her face a picture of maternal concern. "Poor Sakura. She's always been so careful… but sometimes, these things happen."

Hisashi's sharp gaze never left Yui. He studied her carefully, his expression unreadable. "Accidents do happen," he said slowly, his voice measured. "But they're rarely this severe."

Yui stiffened slightly but quickly recovered, her sorrowful expression unwavering. "It was just an argument, Uncle Hisashi. I didn't mean for it to escalate. She was upset, and I should've done more to calm her down."

Hisashi nodded slowly, his piercing eyes narrowing. "Of course," he said softly, though his tone carried a weight that made Yui's chest tighten. "It's fortunate that you were there. Mangetsu must be relieved to have you by his side."

Mangetsu glanced at Yui and gave a small, tired nod. "She's been incredible," he said, his voice heavy. "I don't know what I would've done without her."

Suspicion

The visit was brief, filled with hushed condolences and concerned glances at Sakura's still form. When it was time to leave, Hisashi lingered at the door, his gaze flicking back to Yui. She was helping Mangetsu adjust a blanket over Sakura, her movements slow and deliberate, her face unreadable.

As the Yaoyorozus stepped into the hallway, Momo glanced back. "She's been through so much," she said softly, her voice thick with emotion. "I'm glad she's handling it so well."

Hisashi said nothing, his expression grim as he led the way to the elevator. His mind raced, piecing together fragments of the story Yui had told. The details fit well enough, but there was something about her demeanor that didn't sit right. She was too composed, too rehearsed. And her eyes… those sharp, calculating eyes.

"Accidents do happen," he murmured again, his voice low.

"What was that, dear?" Yuna asked, turning to him.

"Nothing," Hisashi replied smoothly, offering her a faint smile. "Just thinking out loud."

Yui's Act

Back in the hospital room, Yui stood by the window, watching as the Yaoyorozus disappeared into the elevator. Her father was seated by Sakura's side, his head bowed as he held her hand. The soft beeping of the heart monitor filled the room, steady and rhythmic, a stark contrast to the chaos brewing in Yui's mind.

"Yui," Mangetsu said quietly, breaking the silence. "You've done so much for your mother today. Thank you."

Yui turned to him, her face softening into a warm smile. "Of course, Dad," she said gently. "She'll be okay. She's strong."

Mangetsu nodded, his shoulders relaxing slightly. "She is. Just like you."

Yui's smile widened, though it didn't reach her eyes. "Exactly."

She turned back to the window, her reflection staring back at her. In the faint glow of the city lights, her sharp features seemed to shift, her eyes narrowing as her lips curled into a faint smirk.

Accidents do happen, she thought. But they were never accidents when you were in control.

The Rooftop Meeting

The city stretched out beneath Yui Kodai like a vast, glittering organism, its veins pulsing with the neon glow of streetlights and billboards. From the rooftop, the world felt small and insignificant, the hum of distant traffic a dull backdrop to the cool night air. Yui stood near the edge, her silhouette sharp against the sprawling skyline. The wind tugged at her dark hair, but she remained still, her sharp eyes scanning the horizon.

Behind her, the faint creak of footsteps announced his arrival.

"You're punctual," the Alchemist said, his voice smooth and calculated, each word carefully chosen to carry both weight and subtle mockery. He emerged from the shadows, his hood pulled low over his face and his mask concealing his expression. The faint glint of his eyes was the only visible feature, twin embers of something both cunning and sinister.

Yui didn't turn to face him. "I assume you've heard the news."

The Alchemist chuckled, a low, soft sound that sent a shiver down her spine. "I did. Your mother, correct? An unfortunate accident."

Yui smirked, her voice laced with sarcasm. "That's what I told them."

The Alchemist stepped closer, his movements silent and deliberate, like a predator stalking its prey. "And I assume, by the way you're holding yourself tonight, that I'm correct in assuming it wasn't an accident at all."

Yui finally turned, meeting his gaze with a steady, unflinching stare. "You assume correctly."

The Alchemist tilted his head, his mask catching the faint glow of a nearby billboard. "Good," he said simply, his voice carrying a note of approval. "You've exceeded my expectations."

Yui's smirk widened, though there was no humor in it. "I wasn't aware there were expectations to exceed."

The Alchemist chuckled again, his tone shifting to something colder, more calculating. "There are always expectations, Yui. You've just proven you're capable of meeting them. And now, we can use this little… mishap to our advantage."

A Plan in Motion

The Alchemist moved past her, standing at the edge of the rooftop and looking out over the city. "Hisashi Yaoyorozu will be distracted now," he said, his voice thoughtful. "His sister is in danger, and his focus will falter. This gives us a rare opportunity to strike at the heart of the Yaoyorozu family."

Yui crossed her arms, her expression calm but her eyes gleaming with interest. "And what exactly is the plan?"

"Patience," the Alchemist said, turning to face her. "First, we need to set the stage. And to do that, you need to meet someone."

Yui arched an eyebrow. "Who?"

The Alchemist's gaze seemed to pierce through her, even with his mask in place. "Kai Chisaki," he said, his voice dropping to a near-whisper, as though the name itself carried weight. "You may know him as Overhaul. He's the leader of the Yakuza, and my employer. He's expressed an interest in meeting you."

Yui's expression remained neutral, but her fingers tightened slightly against her arms. "And why would he want to meet me?"

The Alchemist's lips curved into a faint smile beneath his mask. "Because you're valuable. And because I've spoken highly of you."

Yui tilted her head, her voice tinged with skepticism. "You've been talking about me behind my back?"

The Alchemist laughed, a low, amused sound. "Don't flatter yourself. I told him you're an asset, nothing more. But whether you live up to that claim is entirely up to you."

The New Drug

The Alchemist reached into his coat, pulling out a small vial filled with a shimmering, iridescent liquid. He held it up between two fingers, the faint light catching the swirling contents.

"This," he said, his voice laced with pride, "is our ticket to controlling not just the Yaoyorozus, but the entire hierarchy of society."

Yui stepped closer, her eyes narrowing as she studied the vial. "What is it?"

"A new form of Trigger," the Alchemist said, his tone almost reverent. "Refined, enhanced, and revolutionary. It enhances quirks without killing the user. Safe in moderation, but dangerously addictive. Over time, the user's quirk will grow dependent on it, unable to activate without another dose."

Yui's gaze flicked to him, her voice low. "And you want to sell this to the Yakuza?"

The Alchemist nodded. "Precisely. Kai Chisaki is always looking for tools to expand his influence, and this drug will do exactly that. Not only does it amplify power, but it floods the body with endorphins and dopamine, creating a euphoria that's impossible to resist. We can control people, Yui. Their quirks, their loyalty, their lives."

Yui's lips curved into a small, dangerous smile. "And you want me to convince him."

The Alchemist's voice dropped, his tone becoming firm. "I'm not sending you to fail, Yui. This is your moment to prove your worth—not just to Chisaki, but to me."

Yui raised an eyebrow. "And if I don't?"

The Alchemist's gaze darkened, his presence suddenly suffocating. "You belong to me," he said softly, his voice a blade wrapped in silk. "As long as you remember that, no one will lay a finger on you. But defiance will not be tolerated."

The Test

Yui studied him for a long moment, the tension between them thick enough to cut. Finally, she nodded, her sharp eyes gleaming with resolve. "I won't let you down."

The Alchemist's smile returned, cold and calculating. "Good. You'll meet him tomorrow night. Make sure you're prepared."

He turned to leave, his coat billowing slightly in the wind as he stepped into the shadows. But before he disappeared completely, he paused, glancing back at her.

"Oh, and Yui," he said, his voice dripping with mock affection. "I'm proud of you. Truly."

And then he was gone, leaving Yui alone on the rooftop, the vial of shimmering liquid glinting faintly in her hand.

The Weight of Doubt

Hisashi Yaoyorozu stood in his study, the warm light of the desk lamp casting long shadows across the bookshelves lining the room. A glass of whiskey sat untouched on the table, the amber liquid catching the faint flicker of light as he leaned against the desk. His thoughts churned like a storm, his normally composed demeanor fractured by the weight of suspicion and regret.

Yuna sat across from him, her expression calm but her gaze sharp. "You're troubled," she said quietly, breaking the silence that had stretched between them.

Hisashi exhaled slowly, his hand brushing over the glass, though he didn't lift it. "Sakura's fall," he began, his voice low and deliberate, "I don't believe it was an accident."

Yuna's eyebrows furrowed, her lips tightening. "Hisashi, you can't possibly—"

"I don't want to believe it either," he interrupted, his tone cutting but not cruel. He looked at her, his dark eyes shadowed with something close to guilt. "But the timing, the circumstances… something doesn't add up."

Yuna folded her arms, her voice taking on a protective edge. "Yui has been through so much, Hisashi. If you confront her with baseless accusations—"

"They're not baseless," Hisashi said sharply, though his voice softened almost immediately. "I know Yui. I've seen the way she's changed. There's anger in her, Yuna, a deep, simmering anger that's been growing for years. And I can't ignore that."

The Eavesdropper

The creak of the door broke their conversation. Hisashi and Yuna turned simultaneously, their eyes landing on Momo standing in the doorway. Her face was pale, her lips pressed into a thin line, and her eyes were wide with shock.

"You think Yui did this?" she asked, her voice trembling with disbelief.

"Momo—" Yuna started, but Momo cut her off, stepping into the room with fists clenched at her sides.

"How could you?" she demanded, her voice rising. "How could you even think that? Do you realize how awful that sounds?"

Hisashi sighed, running a hand over his face. "Momo, this isn't something I want to believe. But I can't ignore the possibility."

"The possibility that she what? Hurt her own mother?" Momo's voice cracked, tears welling in her eyes. "This is why she doesn't talk to us anymore. Why she feels like she doesn't belong. Nobody in this family sees the best in her. She's always put down, always compared to me. It's wrong, Dad. It's so wrong."

Yuna looked down, guilt flickering across her face. Hisashi straightened, his expression hardening even as her words cut deep. "I know," he admitted after a moment. "I know how she's been treated, and I know it's pushed her to the edge. But that doesn't mean I can ignore what's happened."

Memories of a Broken Bond

Hisashi's mind flashed back to that heated moment, just weeks before Sakura's fall.

He had been visiting the Kodai estate, a rare instance of family bonding that had quickly turned sour. The argument between him and Sakura had started small, a disagreement over dinner, but it had escalated when Yui walked in, her presence a silent reminder of the tension hanging over the household.

"You're only saying that because of Momo," Yui had snapped, her gray eyes burning with anger and pain.

Both adults had turned to see her standing in the doorway, her face pale but her trembling hands betraying her emotions. Her voice had risen as she stepped into the room, every word trembling with hurt.

"You're not here for me," Yui had continued. "You don't care about me. You're only defending me because it's upsetting Momo."

Hisashi had opened his mouth to respond, but she hadn't given him the chance.

"Do you even love me, Uncle?" she had demanded, her voice breaking. "Does anyone in this family actually love me? Or am I just… just some failure you all have to put up with?"

Her words had pierced through the room like shards of glass, leaving silence in their wake. Hisashi had looked at her, his usually stoic expression faltering, but no words had come. What could he say that wouldn't sound hollow?

Sakura had stood, her expression twisting with guilt and frustration. "Yui, that's enough."

"No," Yui had snapped, tears streaming down her face. "It's not enough. I'm tired of being compared to Momo, of being told I'm not good enough. I'm tired of feeling like I don't belong in this family."

Her voice had cracked on the last word, and she'd turned and fled the room. The sound of her footsteps echoing down the hall had lingered in Hisashi's mind long after she'd disappeared.

"This is what you've done to her," he had said to Sakura, his voice low and dangerous. "You've broken her."

Sakura had looked away, her expression hardening. "She needs to toughen up. Life isn't kind, Hisashi. If she can't handle a little pressure now, how will she survive in the real world?"

"By being supported, not crushed," Hisashi had shot back. "If you keep this up, you'll lose her, Sakura. Completely."

The Weight of Regret

As the memory faded, Hisashi exhaled slowly, his jaw tightening. Momo's voice broke through his thoughts.

"You don't even know for sure," she said, her tone quieter now but no less firm. "If you accuse her of something like this and you're wrong, it'll destroy what little bond we have left with her."

Hisashi nodded, his expression grim. "You're right. And if I'm wrong, it will push her over the edge. But if I'm not wrong…"

Momo stepped closer, her voice softening. "You're her uncle. If anyone can fix this, it's you. But accusing her isn't the way to do it. She needs support, Dad. She needs to know we're here for her."

Yuna placed a hand on Hisashi's arm, her voice gentle. "Momo's right. Yui's been crying out for help for years, even if it doesn't always look like it. If you go into this with suspicion, you'll lose her forever."

Hisashi looked between the two women, his heart heavy with doubt and regret. He thought of Yui's sharp words, her trembling hands, and the pain that had radiated from her every time she spoke about their family.

He realized, perhaps too late, that this wasn't about proving her innocence or guilt. It was about repairing what had been broken before it was too late.

"I'll handle it," he said finally, his voice steady but weighted. "I won't confront her. Not yet. But I won't ignore this either."

He turned to leave the study, his strides purposeful but heavy, the image of Yui's tear-streaked face burned into his memory.

For the first time in years, Hisashi Yaoyorozu felt uncertain.
