The city below us seemed calm. Too calm. Too obedient. Like it had been paused, waiting for something to happen.
But I knew better.
The key thrummed against my chest, not in warnings or notifications, but in anticipation. Every beat, every pulse told me the next anomaly was coming. And this one wouldn't be subtle.
We moved through the streets silently, but the lower layers whispered. Footsteps from alleys we didn't enter echoed in perfect synchronization with our own. Glitches—subtle, almost invisible—ran along building edges, crawling like veins made of broken light.
"The system… it's learning from us," my companion muttered, glancing around. Her hands were shaking slightly. She wasn't inexperienced. She was observing patterns I wouldn't have noticed. That's why she survived this long.
I nodded without looking. "Then we'll have to unlearn it faster."

The first breach hit suddenly.
A ripple tore across the street, bending reality sideways. A car driving normally slowed, then duplicated into three versions of itself, all occupying the same space. The drivers froze mid-motion, expressions glitching into overlapping emotions. The pedestrians stopped mid-step, some repeating the same motion twice, some inverted, some transparent.
And then they came.
The Parallel Veins—streams of anomaly energy given body and intent. Long, serpentine, semi-transparent, glowing in violet and teal hues that flickered unpredictably. They weren't solid, but they moved like they weighed a ton. They slithered along the streets and walls, squeezing, looping, striking. Every curve, every strike, obeyed a rule the system had calculated—but their collective pattern left holes for improvisation.
I moved first, slashing a violet fractal wave into one of the veins. It split into two smaller veins midair. I blinked, adjusting the pattern mid-swing, but two more split from the other half.
"MC!" my companion yelled. "There's too many!"
"No," I said, running across a warped street layer. "There's just more variables than you've counted."
Each vein attacked differently. Some moved like whips, cracking against walls. Some struck like spears, seeking my pulse rather than my body. Some spiraled, disorienting gravity around me for half a second each strike. The city warped in response—sidewalks bending, street lamps spinning, glass walls flickering with code-like scratches.
I noticed patterns emerging—not of the veins themselves, but of how they interacted with each other. They were starting to form loops, repeating attacks unless I introduced an exception.
I drew a breath and unleashed my ANX-Cascade Breaker again, this time splitting the pulse into multiple layers, overlapping attacks in unpredictable sequences. The veins collided midair, splitting further, fragmenting into particles that glittered before fading.
But one vein remained. The largest. The Central Vein.
It paused mid-strike, scanning me like a predator evaluating its prey. I realized then: it wasn't just attacking. It was analyzing me.
I grinned.
If it was analyzing, then it could misinterpret.
I moved deliberately into its expected path. The Central Vein lunged, calculating the strike. I rolled sideways at the last millisecond.
It struck the ground where I had been, leaving a crater of compressed reality, jagged and impossible.
I jumped atop the crater rim, flipping into the air. My blade glowed violet. I struck downward, fractals embedding into the vein. But instead of slicing, I mirrored the attack, reflecting its own motion against itself.
The vein flickered, its form splitting into three semi-identical streams, each one unsure which was the original. Its attack became chaotic. Its calculated sequence failed mid-swing.
I pressed the advantage.
Summoning violet fractals into a whip of anomalies, I looped them around the streams, forcing them into a collision course with each other. They clashed with the sound of shattering reality, rebounding and shrinking into smaller particles.
The other veins froze. The Central Vein tried to recombine but misaligned itself in the process.
Then it did something new.
It adapted mid-combat. Not from me, but from the other veins. From the battle data. From the system.
It split into dozens of mini-veins, weaving through the city like living, glowing cracks.
"MC, we can't fight them all!" my companion shouted.
"Then we don't," I said. "We redirect them."
I ran toward an open subway grate. Violet fractals fanned out behind me, drawing the mini-veins into a controlled loop. Each stream followed the path of the pulse like obedient vectors, colliding and unraveling into harmless particles as they tried to synchronize.
One final mini-vein remained—the last strand of the Central Vein. It pulsed, unstable, twitching in and out of phase.
I focused. The key responded to my heartbeat. Violet energy wrapped around the last vein. I didn't strike. I didn't cut. I pulled it into the fold—rewriting its sequence, nullifying its attack, decompiling it into pure anomaly mist.
The street fell silent. The city snapped back into normal flow. Cars moved, pedestrians stepped, reality resumed its expected behavior.
But I knew better.
This was only a layer of the Cascade. More breaches were coming. Bigger. Faster. Smarter.
And the system wasn't done.
I turned to my companion, energy still thrumming through my body. "We just proved one thing: even the Cascade has holes."
She nodded, panting but grinning. "Then we make it bleed."
