The Extra is a Genius!?-Chapter 507: The Thing Bound in Chains [I]

The ground began to tremble, not violently, not all at once, but in a slow, uneven way that felt wrong underfoot. It wasn’t the kind of shake that came from an explosion or a spell misfiring. It was heavier than that. Weight shifting. Something large adjusting itself as it moved.

Everyone felt it.

Stone groaned somewhere ahead, a deep sound that carried through the island like a warning. Dust lifted from the street in thin waves, drifting across the ground before settling again.

Then it came into view.

The guardian emerged between the broken structures at the far end of the street, its sheer size forcing the space around it to feel smaller. It wasn’t fast, and it didn’t need to be. Its body was massive, layered with warped metal and dark flesh fused together in a way that looked more assembled than grown. Thick chains were embedded directly into it, wrapped around its limbs and torso, some disappearing into the ground, others biting deep into its frame as if they’d been hammered in place.

At the center of its chest, visible through gaps in the plating, a Shard pulsed steadily. Dense. Bright. Alive with mana.

The chains tugged and rattled as it moved, resisting every step. They weren’t decoration. They were restraint.

And even so, the pressure rolling off it was crushing.

Garron sucked in a breath and staggered half a step without meaning to, one hand pressing instinctively against his chest. It felt like someone had leaned their full weight on him all at once, not enough to knock him down, but enough to make breathing take effort.

Selene’s eyes narrowed as she focused, her attention snapping to the space around the creature rather than the creature itself. "The gravity’s wrong," she said quietly. "It’s unstable."

Elyra had already started tracing sigils in the air, then stopped herself, her expression tightening. "Teleporting near that thing is a bad idea," she said. "Whatever those chains are doing, they’re interfering with space."

Noel didn’t speak at first. He was watching the chains, the way they pulled taut whenever the guardian shifted, the way the Shard’s glow intensified just slightly when it resisted them.

’Contained,’ he realized. ’On purpose.’

Laziel broke the silence, his voice low. "That doesn’t look like something that should be walking around."

"No," Noel replied. "It isn’t."

He kept his eyes on the Shard. "It’s bound."

Selene swallowed. "And it’s still moving."

The guardian took a single step forward.

The ground buckled under its foot, stone sinking and cracking outward in a wide circle. The pressure spiked instantly, slamming into them hard enough to steal the air from their lungs for a brief, terrifying moment.

Noel moved first.

Revenant Fang slid free of its sheath in a smooth, familiar motion, shadows clinging briefly to the blade before settling along its edge. Noel stepped forward as the sword came up, his stance low and controlled, eyes locked on the Shard embedded in the guardian’s torso.

He needed to feel it.

The first strike came fast.

Revenant Fang carved a shallow arc across the guardian’s leg, the blade wreathed in a thin layer of fire as Ignition Surge flared to life. Metal screeched, sparks and embers scattering where the cut landed.

The guardian didn’t slow.

Noel twisted away immediately, shadow folding under his feet as he slid back a step and thrust forward again.

"Voltage Needle."

Lightning ran along Revenant Fang’s edge before snapping outward in a precise, piercing line, aimed straight for the point where chain met armor. The bolt struck, electricity crawling violently across the bindings—

—and then dispersed.

The guardian kept walking.

Noel clicked his tongue softly, already resetting his grip.

"...Alright."

The guardian answered.

Its arm rose, slow and restrained, chains grinding as they pulled tight against its own movement. When it came down, it wasn’t fast—but the weight behind it bent the air itself, stone fracturing before the impact even landed.

Garron stepped in without hesitation.

Mana surged through his body as he planted himself in front of the blow, muscles swelling under raw reinforcement. He caught the descending arm with both hands.

The impact hit like a collapsing wall.

Stone detonated beneath Garron’s boots as he was driven backward, trenches tearing through the plaza as he skidded several meters before forcing himself to stop. His arms shook violently, teeth clenched, breath ripping from his lungs as he held the line.

He held.

Barely.

The guardian pulled its arm free, chains rattling as Garron staggered and dropped to one knee before forcing himself upright again, chest heaving.

"...I can stop it," Garron said through a strained breath. "Not forever."

"Then we don’t let the ground fail," Elyra said immediately.

Runes ignited beneath them as Reinforced Ground spread outward, stabilizing the fractured stone before it could give way. A Warning Beacon flared into existence near the guardian, floating high and bright, marking the zones where its steps distorted the terrain.

Elena moved next.

Roots erupted beneath the guardian’s legs. "Root Snap."

The vines wrapped tight—then snapped apart like brittle twigs.

She followed without hesitation. "Vine Fang."

A spear of hardened root slammed into the guardian’s side. It bit in, slowed for half a heartbeat—

—and shattered.

Selene raised her hand, eyes sharp. "Gravition Hold."

The space around the guardian thickened violently, gravity spiking hard enough to warp the air. This time, it reacted. Its next step came slower, chains screaming as they strained to hold.

Selene exhaled. "It’s not ignoring the gravity."

"It’s resisting it," Noel finished, Revenant Fang lifting again, shadow and flame coiling along the blade.

His eyes narrowed.

"Then it’s not immune," he said. "It’s just strong."

The guardian hit again.

This time, it didn’t feel like a slow mountain shifting forward. It felt like something heavy learning how to move with intent. The chained arm snapped through the air with a sharper angle, the Shard in its chest pulsing once as if it had decided it didn’t need to test them anymore.

Noel’s eyes narrowed and his body moved before his mind finished the thought.

Shadow folded under his feet.

"Shadow Step."

He vanished from where the blow would’ve crushed him and reappeared two streets’ worth of distance to the side, coming out of a patch of darkness cast by a broken wall. The moment his boots hit ground, his core pinched hard, like a bruise pressed too deep.

He steadied his breathing anyway.

’Not again. Not like that,’ he thought, jaw tightening as he felt the drag in his mana. ’I can’t spam it.’
