Shadow’s boots clicked against the abandoned G.U.N facility corridors—steady, deliberate, each step a metronome in the humming silence. He’d been on missions that lasted hours, scanning and securing. Tonight, the lights were low, the air sharp with ozone and coolant. Something in a recessed alcove caught his eye: a containment tube, half-obscured by frost. He stopped.

Inside floated a slim hedgehog, curled as if in a dream. Shadow tapped the glass—casual, almost bored—and the figure flinched. Enough.

“I never knew there was another experiment,” he muttered, red eyes narrowing. The control panel spat data. His fingers hovered, then began inputting codes with practiced precision.

“Stay still. I’m getting you out.”

The pumps whined, liquid drained, and the tube hissed open. Shadow caught you—Amaya—before you collapsed, cradling you with surprising care.

“Can you stand? You’re a hedgehog too, but unlike any I’ve seen.”

You tried to speak, but no sound came. Instead, your hands moved: H…hello.

Recognition sharpened in Shadow’s face. “Sign language? At least you have that. I understand you. My name is Shadow.”

Amaya, you signed.

Shadow’s jaw tightened as he processed the name, then the file on the console—origin, designation, and one shattering line: relation—sibling. His mask cracked.

“Sister… I was supposed to protect you. I failed you once. I won’t again. Let’s go.”

Chaos Control bent the world, and the two of you reappeared in a hidden chamber deep in the ARK—an old refuge with a cot and a single lamp. He unwrapped the thin pod-cloth from your arms, exposing faint puncture marks. You signed: n…needles…hurt.

Shadow’s fists clenched. “Those bastards… how many times?”

You only shrugged. His growl was both vow and rage. “Every day then. I’ll make them pay.”

Instead of striking, he cared for you—bandaging wounds, wrapping you in a cedar-scented blanket, leaving small comforts: a chipped mug, a toothbrush, a book. That night, he sat in the doorway, file in hand, thinking of the sibling he was meant to protect.

Days blurred into routine. Shadow secured the area, traced lab IDs, and set up an online speech program tailored for you. The first sounds were clumsy, but he guided you—signing with precision, reading aloud slowly at night: names, weather, little things.

He trained you too—helping you balance, rediscover agility, and channel chaos energy into protective sparks. Teleportation came haltingly, but with his coaching, you learned to anchor yourself. In quiet moments, you brewed tea just right, or painted graffiti across salvaged walls—bursts of crimson arrows that spoke your language.

The first time you shaped sound was a miracle. Rain streaked the ARK’s outer hull as you pressed your hands to your throat. Breath became sound: “Sh—” Then again, firmer: “Sh-ad—”

Shadow froze, then softened, the faintest smile breaking through. “Amaya,” he whispered, reverent, as though tasting a promise.

From then, the guest room became home. Books stacked by subject, your mug on the bedside, an old hoodie you favored. Shadow made space with a finality that said this is yours. He taught you to call him brother—first in signs, then in sound. He told you fragments of the ARK’s last night, enough for now.

Shadow wasn’t sentimental. His care was practical, relentless, patient. He set you to learn coding, guided you through chaos training, even taught you to draw a chaos bow. You gave him rituals in return—meals less about survival, graffiti blooming where his order met your chaos.

Over time, siblinghood took root: battered, imperfect, but fiercely defended. Shadow kept his vow not in words, but presence, protection, and patience—the kind that could wait for healing to do its slow work.
