Harry Potter and The Heir of the Shadow Throne

Shadow Shenanigans and Mom's Magic 101

The Scottish Highlands were a misty, chaotic playground—cliffs that tripped me, valleys that swallowed my socks, and winds that made my hair poof like a bad hair potion. Five years since Truck-kun yeeted me into this world, landing here with Mom in 1987, I was now six, scrawny and scrappy, with wild dark hair and eyes twinkling with mischief—or maybe pollen from the bushes. But I was still Zephyr Riddle, Voldemort's kid, and that secret was my personal isekai comedy gone wild. As a transmigrator, I knew Harry Potter inside out—Hogwarts, Horcruxes, the whole shebang—but being stuck as a kid with shadow powers? That was my new punchline.

We'd camped in a cavern under a cliff, its walls plain and boring, no fancy runes or anything. Mom had turned survival into a circus—scavenging herbs (I once ate one, thinking it was candy, and burped sparkles for an hour), lighting fires with her wand (which once set my cloak on fire), and dodging Aurors who tripped over their own robes trying to find us. My Shadow System, that wacky magical pop-up in my head, had upgraded me from drooling baby to klutzy kid wizard. But I wasn't satisfied—I wanted powers that didn't end in face-plants or shadow burps.

This morning, I stood in a clearing, mist tickling my nose until I sneezed. My patched cloak—Mom's old robes glued with magic—flapped as I squinted at the Shadow System's latest prank:

Task Active: Master Shadow Powers. Reward: Shadow Pulse Mastery (3 Uses/Day, Enhanced Range). Failure: Power Stagnation (Ticklish Weakness). Time Limit: 48 Hours.

"Alright, system, don't make me sneeze into oblivion!" I laughed, clenching my fists. My voice was high-pitched and bouncy, but my otaku brain was sharp. "Show me the OP stuff, system, I've already got the whole plot knowledges, but these shadows better not flop like a first-year's Wingardium Leviosa!" I'd mastered Shadow Step—teleporting 10 meters via shadows. "Hm, Shadow Step—this thing's way better than Apparition!, no ministry tracking, no evidence" I thought, grinning. Also, no loud crack like those stiff wizards—just a silent whoosh, I wonder if one day I could just teleport like Jinwoo" That is more like swap than teleport! I'll think about it later, Let's try this out".

I closed my eyes, focusing on the shadows and they felt like wriggly spaghetti. "Shadow Surge!" I yelled, flailing my arms. A blob of black energy shot out, smacking a tree and cracking its bark—then splattering me with shadow goo. I hit the ground with a thud, covered in goo. "Ugh, gross! I'm a shadow slob—Truck-kun, you owe me for this!" I groaned, wiping my face. The system chimed:

Skill Progress: Shadow Surge – Effectiveness: 70% (Range Increased to 15 Meters). Warning: Goo Risk Detected.

"Goo risk?!" I whined, standing up and shaking off the sludge. "This is worse than Snape's dungeon vibes!"

I tried again, focusing so I didn't look like a shadow mess. The surge formed a tighter beam, blasting a rock into pebbles. "Ha! Take that, dumb rock—eat my shadow power!" I cheered, doing a victory jig—until my cloak tangled my feet, and I face-planted.

Skill Unlocked: Shadow Sense (Detect Magical Threats, 50-Meter Radius). Progress: 30% (Clumsiness Penalty).

"Clumsiness penalty?!" I grumbled, rolling over. But Shadow Sense buzzed—a ticklish tingle, then I sensing Mom's magic nearby. I spun, spotting her stomping over, her wand glowing like a mad flashlight. "Zephyr, quit turning the clearing into a shadow comedy show!" she yelled, her auburn hair a frizzy mess. "You'll summon Aurors who'll trip over their own wands!"

"Aw, Mom, chill—I'm just leveling up my 'isekai' powers!" I grinned, scrambling up. "Watch, I'm a shadow ninja!" I triggered Shadow Bind on a butterfly fluttering by—shadows coiled around it, pinning it to a bush. It fluttered, farted sparkles, and escaped. "See? I'm basically a wizard now, or should I be a prankster, with this skill, I could better than Fred and George!"

Mom snorted, shaking her head. "You're a walking pratfall, kiddo. Just don't bind me, or I'll hex you into a shadow balloon!"

She sat down, patting the grass. "But look at all the things that you do, I really wonder if that is magic or something else, anyway, you are his son, you are one hundred percent not a normal kid.

Since you're so hyped, let's talk about Hogwarts, even we have to wait for few more years but I have to give you an idea of what about to happen."

"Sweet!" I plopped beside her, wiping goo off my hands. Zephyr mumbling to himself

"I already know the basics, Sorting Hat, four houses, Quidditch, Room of requirement, Basilisk, then what else she could possibly tell me thou?"

Marigold just goes over all the basic stuff that I already know, so kinda waste of training time.

That afternoon, I practiced more, accidentally binding a squirrel that chittered and farted sparkles before escaping. "Mom, this Shadow Sense is ticklish—can it find Hogwarts?" I asked, scratching my nose.

That night, in the cave,

I stared at the system's glow, shadows dancing on the walls. "This is such a weird gig,"

I started to think about the future. "I'm Voldemort's son and no matter I like it or not, I tied to that no-nose goof's legacy, but what should I do with him, against him? ignore him? or just hide? And those Horcruxes… maybe I should dig up where they are and start to destroy it, just for safety since having a dad haft immortal is quite crazy, but what if I trip into his trap? Nah, I don't think so I'll do that?, That should be Harry and Dumbledore stuff"

I start to picture Harry at Hogwarts, probably slipping on butterbeer, and snorting. "I'll meet him at 11 and hope I don't shadow-slap him by accident because of all nonsense, heroic thing that teenage kid think he could handle!"

But there is one thing that I knew, with this system, with my memory intact, the path I walk will be wacky, but it's mine.

I will be the one who controls my fate, not Voldemort, not Harry, and yes not DUMBO.
