A Tapestry of Secrets and Shadows

"What is that?" Ren whispered.

"Doll Echo," Mizuki replied, her voice barely audible. "One of the worst. Don't look at its face if it turns around."

As if hearing them despite the distance, the child-thing's head rotated 180 degrees with a sickening crack. What should have been a face was instead a blank, porcelain mask with a single crack running down its center. As they watched in horror, the crack widened, revealing darkness behind it and a sound emerged—the laughter of a young girl, distorted as if played backward.

"Don't move," Mizuki hissed as the thing began walking toward them, its body still facing the opposite direction while its head remained fixed on them. "My concealment won't work if we move now."

The Doll Echo continued its unnatural approach, its broken laughter growing louder. With each step, the air around it seemed to warp, reality itself bending away from the abomination.

In Ren's mind, his mother's Echo trembled. That thing... it isn't just an Echo. It's something else. Something worse.

The Doll was now less than ten meters away, still coming directly toward them with that horrible backward walk. The crack in its face had widened further, revealing a void filled with what looked like hundreds of tiny, groping hands.

Ren felt his control slipping, panic threatening to overtake him. The jade pendant burned against his skin as his mother's Echo responded to his fear.

Don't, she warned. If you call my power now, it will see us for certain.

The Doll Echo stopped five meters away, its head tilting at an impossible angle. The laughter had ceased, replaced by a soft, rhythmic clicking sound.

"It's sensing us," Mizuki whispered. "But it can't quite see through my concealment."

For what felt like an eternity, they remained frozen as the Doll Echo clicked and twitched, its blank face searching. Finally, with a sound like breaking glass, the thing's head rotated back to its original position, and it continued down the street away from them.

Ren released a breath he hadn't realized he was holding.

"What was that thing?" he asked when the Doll Echo was finally out of sight.

"A manifestation of childhood trauma," Mizuki said grimly. "Specifically, abandonment and abuse. One of the oldest Echo types, and hardest to destroy."

She gestured for them to continue, now taking a different route. "We should hurry. That thing was heading away from your neighborhood, which is good, but there are others out tonight."

As they moved through the darkened city, Ren saw evidence of the chaos everywhere. Abandoned vehicles, broken windows, occasionally the remains of what might have been people—twisted forms covered in the same ashy residue left by the Wraith Echo.

"How many people have died?" Ren asked, his voice hollow.

"Hundreds in Tokyo alone," Mizuki replied without emotion. "Thousands worldwide. And it's just beginning."

They turned a corner, and Ren recognized the street—they were just two blocks from his apartment building.

"Almost there," he said, picking up his pace.

Mizuki caught his arm. "Wait." Her black eyes were focused on something ahead. "Something's wrong."

Ren followed her gaze. His apartment building looked intact, but there was an unnatural stillness to the area. No movement, no lights, despite the emergency broadcasts telling people to stay home.

I sense it too, his mother's Echo whispered. A presence. Watching. Waiting.

"Is it another Echo?" Ren asked, dread building in his chest.

Mizuki shook her head slowly. "Worse. It's human." She pointed to barely visible figures positioned on neighboring rooftops. "The Hollow Choir. They're waiting for you."

"How? How did they know I'd come here?"

"Because it's where your father is," Mizuki said, her voice softening slightly. "And they know you'd try to save him."

Cold fear gripped Ren's heart. "We have to get him out of there."

"It's a trap, Ren," Mizuki warned. "That's exactly what they want you to do."

"I don't care," Ren said, the jade energy beginning to flow around his hands again. "I'm not abandoning him."

Before Mizuki could stop him, Ren broke free from her concealing shadow and sprinted toward his building. Behind him, he heard her curse, then follow.

The moment he emerged from Mizuki's protection, Ren felt exposed. The night air seemed to thicken around him as he ran, as if the darkness itself was reaching for him.

Behind us! his mother's Echo cried out in warning.

Ren glanced back to see the shadows coalescing into a towering figure—another Wraith Echo, even larger than the first.

Mizuki had caught up to him, her own Echo power flaring around her in tendrils of shadow. "Keep moving! I'll hold it off!"

Ren hesitated, but Mizuki shoved him forward. "Go! Find your father!"

As Ren ran toward his building, he could hear the sounds of combat behind him—Mizuki's powers clashing with the Wraith Echo in a cacophony of unearthly shrieks and tearing shadows.

The entrance to his apartment building loomed ahead. The security door was ajar, the lobby beyond dark and silent. Every instinct told Ren to be cautious, but fear for his father drove him forward.

He burst through the door, jade energy flowing around him in a protective shell. "Dad!" he called out, his voice echoing in the empty lobby. "Dad, are you here?"

No response.

The elevator was out of service, so Ren took the stairs, taking them three at a time with his Echo-enhanced strength. Their apartment was on the sixth floor. As he climbed, the silence grew more oppressive. No sounds from any of the apartments he passed. No signs of life at all.

Something is very wrong, his mother's Echo whispered. The people... I can't sense anyone in the building.

Ren reached the sixth floor, his heart pounding. The hallway was dark except for the faint glow of emergency lighting. Their apartment was at the end—number 602.

The door was closed but unlocked. It swung open at his touch.

"Dad?" Ren called, stepping cautiously into the darkened apartment.

Silence greeted him. The living room was exactly as he remembered it from that morning—his father's coffee cup still on the table, Ren's school bag by the door. Nothing seemed disturbed.

But there was a smell—metallic and wrong.

Ren, wait, his mother's Echo pleaded. Something isn't right.

Ignoring the warning, Ren moved deeper into the apartment, toward his father's bedroom. The door was closed. As he reached for the handle, he noticed something dark and wet seeping out from beneath.

His hand froze in midair.

No, the Echo whispered. Oh, Ren, no...

With trembling fingers, Ren pushed the door open.

The bedroom beyond was a nightmare made real. The walls, the ceiling, the bed—all were covered in dark, congealing blood. And in the center of the room, illuminated by the moonlight streaming through the window, hung his father's body—suspended by hooks and wire in a grotesque, ritual posture.

Ren's mind went blank with horror. A scream built in his throat but never emerged. He stood frozen, unable to process what he was seeing.

Movement in the corner of the room caught his eye. A figure stepped out of the shadows—the masked woman from the Order facility, her porcelain face expressionless.

"I am sorry for this," she said softly. "Truly. But we needed you to fully awaken."

Behind Ren, the apartment door slammed shut. Footsteps approached as more masked figures entered the room.

"Grief," the woman continued, "is the most powerful catalyst for Echo resonance. Your mother's death created your first bond. But for what comes next, we needed... more."

Rage and despair exploded within Ren. The jade pendant burned like a star against his chest as his mother's Echo responded to his emotions. But something else was happening too—something new. A second presence was forming within him, born of his fresh grief and rage.

"You murdered my father," Ren whispered, his voice distorted by power and emotion.

"We helped him transcend," the masked woman corrected. "His sacrifice will fuel your ascension."

The jade energy around Ren began to change, darkening at the edges. His mother's Echo cried out within him as a new power fought for dominance—something born of his hatred for these cultists.

Ren, don't let it take hold! his mother's Echo pleaded. Your rage is creating a new Echo—a Vengeance Echo. If it bonds with you alongside me, you'll lose yourself!

The masked cultists had formed a circle around Ren, chanting in a language he didn't recognize. The air in the room began to thicken, to swirl with dark energies.

"Yes," the lead cultist said. "Feel it form within you. The Guardian and the Avenger—two Echoes in one Resonator. A Dual Resonance not seen in centuries."

Through his grief and rage, Ren became aware of a new sound—breaking glass, shouts of alarm from the cultists near the windows. A figure burst into the room in a whirlwind of shadow—Mizuki, her face bloodied but determined.

"Ren!" she shouted. "Don't let them complete the ritual!"

The masked woman turned toward the interruption, raising her hands to unleash her own Echo's power. Mizuki dodged the attack and fought her way toward Ren, black energy swirling around her.

"Fight it, Ren!" she yelled over the chaos. "Don't let your grief create a second Echo! They want you to become a Gateway!"

The word penetrated Ren's rage-clouded mind. Gateway. Something about it triggered a memory of what Commander Sato had said about Echoes that had been hidden for centuries. 

Inside him, the conflict raged as his mother's protective Echo battled against the forming Vengeance Echo. The jade pendant burned so hot it was searing his skin, while a second sensation—like ice spreading through his veins—heralded the new Echo's birth.

Choose, Ren, his mother's Echo begged. You must choose which path to follow.

Around him, Mizuki fought desperately against the cultists, but she was outnumbered. The masked woman had retreated to Ren's father's body, drawing symbols in the blood while continuing her chant.

With the last of his rational thought, Ren made his choice. He focused not on his rage, not on his grief, but on one simple truth—his mother had remained as an Echo to protect him. To keep him safe. Not to avenge, not to destroy.

Protect, he thought. That's what she wanted. What she still wants.

The jade pendant flared with blinding light. The forming Vengeance Echo writhed within him, fighting against his rejection, but Ren held firm to his choice.

With a scream that was both physical and psychic, Ren released the building Vengeance Echo—not into himself, but outward. The dark energy exploded from his body in a shockwave that threw the cultists against the walls.

The masked woman cried out in alarm. "No! You must contain it! Become its vessel!"

But it was too late. The Vengeance Echo, denied a Resonator bond, took form in the center of the room—a towering figure of shadow and flame, vaguely humanoid but constantly shifting. Where its face should be was Ren's father's face, contorted in agony and rage.

For one terrible moment, the newborn Echo hovered there, radiating malevolence. Then, with a roar that shook the entire building, it turned on the cultists who had created the conditions for its birth.

What followed was a slaughter. The Vengeance Echo tore through the masked figures with terrible efficiency, ignoring their Echo powers, their pleas, their attempts to flee. Blood and darker substances splattered the already desecrated room.

Mizuki fought her way to Ren's side, grabbing his arm. "We need to go. Now!"

Ren stood transfixed by the horror before him, his mother's Echo maintaining a protective barrier around them both.

"Ren!" Mizuki shouted, shaking him. "That thing won't distinguish between them and us once it's done with them! We have to leave!"

The masked woman was the last one standing, her Echo power—tendrils of black energy similar to the Wraith Echo—failing against the Vengeance Echo's onslaught. As the newborn Echo closed in on her, she locked eyes with Ren.

"This changes nothing," she gasped out, blood seeping from beneath her mask. "The Gateway will still open. The Great Echoes will return. And you will be their Herald, willing or not."

The Vengeance Echo engulfed her, cutting off her final words in a gurgle of blood.

Mizuki pulled Ren toward the window. "We need to jump. Can your Echo protect us from the fall?"

Ren nodded numbly, still in shock from everything that had happened. Behind them, the Vengeance Echo turned, having dispatched the last cultist. It focused on Ren, recognition flickering in its fiery eyes.

"Go!" Mizuki shouted, pushing Ren through the broken window.

They fell six stories, Ren's jade Echo energy expanding to cushion their landing. The moment they hit the ground, Mizuki grabbed Ren's hand and began running, her concealing shadows flowing around them both.

Behind them, the entire sixth floor of the apartment building exploded in dark flames as the Vengeance Echo began its hunt.

"Where are we going?" Ren gasped as they ran, his mind still reeling from the night's horrors.

"Somewhere safe," Mizuki replied grimly. "Though I'm not sure anywhere is truly safe anymore." She glanced at him. "I'm sorry about your father. Truly. But we need to keep moving if we want to survive."

Ren ran blindly, letting Mizuki guide him through the chaos-filled streets of Tokyo. Inside him, his mother's Echo wept for his father, for what Ren had witnessed, for what he had almost become.

And somewhere behind them, a newborn Vengeance Echo—created from Ren's grief but rejected as a bond—hunted through the night, growing stronger with each life it claimed.

The Resonance Surge continued to build. And Ren Nakamura, marked by both factions as something called a "Gateway," fled into the darkness, carrying the weight of two deaths and the terrible knowledge that this was only the beginning.
