Double Dagger Delinquent

Chapter 158 Sin

A deep killing intent stirred within the dark lair. Alessandra sensed everything—the chill creeping across her skin.

“I will gladly accept any punishment,” she said calmly, her voice unwavering.

“Just allow me to finish recounting all my sins, please...”

Each day, she felt a little better. A little lighter.

She even felt proud of herself—just a bit.

Today, I didn’t hurt anybody, she thought.

However, Ryuuji grew restless.

Finally, he confronted her.

“Mamoru, why have you been avoiding us?” he said, standing in front of her with a serious expression.

“And you still haven’t answered my confession.”

Alessandra froze, surprised. Her chest tightened—but she remained resolute.

“I’m sorry,” she said. “But no.”

She met his eyes.

“I’m not like you guys. I… I’m different. I won’t hurt anyone anymore.”

And with that, she walked away.

Ryuuji’s face twisted in anger. His eyes turned cold.

Alessandra, however, felt a quiet sense of relief.

She had finally cut herself off from them.

It had been weeks since she last saw Iryoku.

Yet she knew there was still something she had to do.

She needed to repent—truly. Only then could she return to him.

She found Kana and followed her into the restroom. Inside, a girl who had been washing her hands suddenly rushed out, leaving them alone.

Kana reacted at once. She began to tremble, her eyes filling with tears.

“No—!”

She had thought the bullying was finally over. Alessandra hadn’t bothered her for weeks.

But Alessandra had come for a different reason.

She stepped closer, then bowed her head.

“I’m sorry, Kana,” she said.

“I’m sorry for everything—for hurting you.”

Kana stared at her, stunned.

“…What?”

“I’ll never hurt you again,” Alessandra continued. “Or anyone.”

She turned, ready to leave.

Kana’s voice stopped her.

“Just like that, you’re ending this?” she said, shaking. “You… you think a simple sorry is enough?”

Tears streamed down her face.

“You don’t know how hard it’s been for me. I have no friends. I’m alone. Nobody wants to come near me. I can’t even sleep at night—because of you.”

Remorse crashed into Alessandra’s chest.

Then Kana’s expression twisted, something unhinged flashing in her eyes.

She reached into her pocket.

Only recently, for her birthday, she’d received it—a flip phone. Rare. Expensive. Something most families couldn’t afford for their children. Kana had never imagined it would matter.

Until today.

Someone had shared it. Kana had wondered why—had hesitated to use it, unsure if it would really change anything.

Now she snapped the phone open and held it toward Alessandra.

A video.

Pixelated. Grainy. But unmistakable.

Scenes from the warehouse flickered across the small screen.

“This video… it’s been passed around between students,” Kana said. “Someone just leaked it.”

A hollow laugh escaped her.

Alessandra’s body began to shake as she stepped closer.

She stared at the screen—

And saw herself.

Punching the bound boy.

Her face twisted with rage, her mouth screaming curses, her fists striking again and again with inhuman violence.

Laughter echoed in the background.

Her breath hitched.

Then came the kick—the inevitable destruction of the helpless body.

Alessandra clapped a hand over her face as tears spilled freely. Her knees nearly gave out.

She had done that.

Seeing it from another angle—from another person’s eyes—made it unbearable.

But Kana’s voice cut through her.

“Hey. Don’t look away, there’s more.”

Alessandra forced herself to look back at the screen.

The video continued.

It showed Ryuuji kissing her—then the footage cut out, skipping ahead.

When it resumed, Ryuuji had already turned back toward the bound boy.

Irritated, he struck him again—harder this time. The boy’s body jerked uselessly, muffled cries spilling from beneath the bag.

Ryuuji reached up.

And tore the bag away.

Alessandra’s soul shattered.

It was Iryoku.

His face was swollen, streaked with tears and sweat. A rag was stuffed deep in his mouth, his jaw shivering uncontrollably. His chest hitched as he fought for breath, broken sobs and whines forcing their way out.

“Mm—mmhh—!”

Ryuuji yanked the rag free.

Iryoku gasped violently, choking on air like he was drowning.

“Ah—hh—ahh—!”

His voice cracked completely as he sobbed. “P-please… stop… p-please…”

He tried to pull his arms together, to curl in on himself—but the ropes held him spread open, exposed and helpless.

Ryuuji grabbed a fistful of his hair and wrenched his head up.

“Bring the phone,” Ryuuji said. “Let’s show this bastard.”

Another phone—one that had also been recording the torture—was brought over.

Iryoku shook his head violently, tears spraying from his eyes.

“N—no—!” he gasped, his voice splintering between sobs and shallow breaths.

“Th—that’s n-not—!” He choked, coughing hard, the words barely forming.

“Y-you’re l-lying… A-Ale Onee-chan…?”

His voice cracked at the end, dissolving into a broken, pained whimper as his body shook uncontrollably.

The phone was shoved inches from his face.

He saw her—attacking him.

His lips trembled as if trying to speak, but nothing came out at first.

“N-no…” he whispered.

His head shook again and again, weak and desperate, like a child refusing to accept what he was seeing.

Ryuuji leaned in close, his voice dripping with venom.

“I told you from day one, you piece of shit. Alessandra is mine. Mine only.”

He laughed.

“Look at you. Crying like a bitch.”

“She hates you.”

“You’re just a toy she used.”

Ryuuji tilted the phone even closer.

“She beat you herself. Smiled while doing it.”

“And now?” His grin widened. “You’re not even a man anymore.”

Then Ryuuji pulled the phone back and paused the video on a single frame.

He shoved it forward again.

“Look.”

Iryoku’s eyes locked onto the frozen image.

Alessandra and Ryuuji—kissing. It looked intimate. Passionate. Like a couple in love.

Ryuuji's voice sneered, "You don't know just how many times she's been mine. That body of hers... so tasty."

Finally, something inside Iryoku shattered.

A broken sound tore from his throat—half sob, half scream. It was raw and animal, ripped from deep in his chest, as if he were trying to force his body to move—to fight, to reach Ryuuji, to destroy him with anything he had.

His muscles strained uselessly against the ropes.

But the strength never came.

The sound collapsed into a weak, trembling whine.

His shoulders shook violently, then sank inward, folding beneath a weight far heavier than the restraints. Whatever had been keeping him upright finally gave out.

Tears kept falling, dripping silently onto the floor.

His eyes lost focus—empty, staring at nothing.

The video ended, cutting off on Kana’s phone.

Alessandra stood rooted in place.

Her vision blurred, the room spinning as if all the air had been ripped from her lungs. Her eyes were empty, glassy, stripped of all light.

Kana closed the flip phone.

A dark, satisfied grin crept across her face.

“Hahaha… oops,” she said softly. “So he really mattered to you.”

She tilted her head, watching Alessandra break.

“How does it feel… to lose everything?”

She spread her arms wide.

“I don’t care if you want to hurt me again. Go on. Do it.”

Alessandra didn’t move.

Then she turned—and ran out of the restroom.

Her footsteps echoed sharply as she sprinted down the hallway, nearly slipping on the polished floor. Students glanced up in surprise as she rushed past them.

Her chest burned. Her breath came fast and uneven, each inhale scraping her throat as she pushed herself harder.

She cut through the next corridor

At last, she reached his classroom.

“Iryoku—!”

She burst through the door.

A few students were inside, startled by her sudden entrance.

“Have you seen Iryoku?” she asked, breathless.

They all shook their heads.

Her heart sank further.

She scanned the room and spotted Ryuuji’s younger sister, Mika, sitting in a corner with a few girls gathered around her.

“You,” Alessandra snapped as she strode toward her, each step heavy.

Mika flinched.

“Ah—y-yes?”

“Did Iryoku really do something to you?” Alessandra demanded. “Tell me!”

Mika blinked, fear flickering across her face.

“W-Who…?”

Alessandra’s heart dropped even more. She doesn’t even know him.

Her fist clenched tightly.

For a split second, a dark thought crossed her mind—Should I take revenge on Ryuuji through his sister—by destroying her in a way even crueler than what he had done to Iryoku?

The idea made her breath hitch.

She was pulled from her thoughts when another boy spoke up, uneasy, sensing the tension in the room.

“Taiyou… he hasn’t come to school in quite a while,” he said. “So we don’t really know what happened to him. He usually doesn’t talk to anyone…”

Alessandra didn’t wait to hear the rest.

She spun around and rushed out of the classroom.

In the hallway, she nearly collided with someone.

Ryuuji.

He stood there, his expression unreadable—then it slowly twisted into a wide smirk.

Alessandra clenched her fists and tried to push past him.

She stopped.

Turned.

And punched him square in the face.

The impact sent him crashing to the floor.

“Fucking bitch,” he groaned.

She glared down at him, her eyes burning with hatred, then turned and ran.

Behind her, loud laughter echoed through the hallway. Ryuuji’s voice followed, mocking and cruel.

“Hahaha—go on, go look for that ruined runt, bitch!”

She clenched her jaw, a whimper slipping out despite herself.

Alessandra ran as fast as she could, her breaths tearing in and out of her chest, ragged and uneven.

She vaulted over the front fence at the school entrance.

“Hey! Where are you going?” a teacher shouted after her.

She didn’t look back.

The only thing that mattered was finding him.

And apologizing.

She was drowning in shame and guilt. Part of her wanted to disappear… but she couldn’t bear the thought of losing him too.

“I’m sorry… I’m sorry…” she whispered as she reached his house, her entire body trembling.

She forced herself to steady her breathing.

She was ready to kneel.

To be struck.

To accept anything.

Tears streamed freely down her face.

But as she stepped closer, something felt wrong.

The house was silent.

The windows were shut.

The small garden at the entrance lay neglected—

weeds climbing higher than they should have.

She knocked on the door.

No answer.

She knocked again.

Then again.

Panic crept in.

Her knocks grew harder, frantic, desperation taking hold. She rushed to a window and tried to peer inside.

Her eyes widened.

The house was half empty.

Several pieces of furniture were gone.

She tried to open the window—but it was locked.

Her heart pounded violently. She ran to another window—nothing.

Another—still nothing.

Her breath caught in her throat.

Nearby stood a tree close to the second-floor window—the one that led to his room. Long ago, she had climbed it the same way to reach him.

Her hands shook as she began to climb, her body trembling. Images of Iryoku’s destroyed face flooded her mind, and tears streamed down her cheeks.

When she reached the window.

It was open.

Exhausted, she pulled herself inside.

Nothing.

Only the bunk beds remained—the ones belonging to Iryoku and Kota. She looked around the room: the TV, the game console, the toys, the clothes—

All gone.

Her legs gave out.

She collapsed to her knees beside Iryoku’s bed.

“Waaaaaah…!” she cried uncontrollably.

“I’m sorry… where are you, Iryoku? Where are you…?”

She buried her face against the wooden frame, sobbing violently, her head shaking from side to side. Slowly, she leaned forward until her weight rested against the bed. Then she slid onto the wooden frame completely, curling in on herself—thrashing weakly, whimpering.

“Ahhh…”

At last, she lifted her head.

Between the wooden planks of the upper bunk, something red was wedged.

She reached up and pulled it free.

A red envelope.

Memory stirred—long ago, she recalled Iryoku fumbling nervously with something in his bag. Red paper. She hadn’t thought much of it at the time.

She wiped her tears and opened it.

The envelope was elegant, a deep, beautiful shade of red. It looked as if it had once been crumpled—then carefully smoothed out again.

She began to read.

--

Ale Onee-chan,

I know I’m small, weak, and not handsome.

I know I wasn’t there to save our brothers.

I know all my weaknesses.

But being with you has always given me the strength to keep going.

I promise—I will grow taller. I will become stronger. I will become better.

I will be the one who protects you and our brothers.

I will find them. We will find them together.

That’s why I wanted to gather my courage and tell you how I feel.

Since the day I first met you, I’ve been in love with you.

I love you with all my heart.

Please go out with me… and be with me forever.

—Iryoku

--

Her trembling worsened as she clutched the letter to her chest, sobs tearing from her throat as the weight of realization crashed down on her.

What she had done.

The love she had never noticed.

The pure love she had destroyed.

“He… loved me…” she cried, her voice cracking apart, sobbing uncontrollably.
