"....hmmm"
Dev sat cross-legged on his bed, staring at the floating system screen in disbelief. His golden eyes flickered as he took in the insanity before him.
[Shop Unlocked!]
[Welcome to the Infinite Realms System Shop! A marketplace beyond space and time! Here, you can purchase abilities, skills, weapons, and even artifacts from every world!]
His jaw nearly hit the floor.
"Wait… every world?! Like anime, comics, movies, novels—everything?!"
Excitement surged through his veins as his eyes darted over the items listed in the shop.

Dev's brain crashed.
"This is… this is beyond broken! This is multiversal cheating!"
He wanted everything. But then he checked his balance.
[Current OP: 1000]
"...Damn it."
He needed to buy smartly.
"Alright, let's not be stupid and go broke immediately."

---------------------————--------------------------
A sleek black suit materialized on his bed. He ran a hand over it. The fabric was smooth, flexible, and felt like a second skin.
"Damn… I look like a futuristic ninja assassin."
[Ooo~ Do you want a cool name to go with it? Maybe 'Shadow Phantom' or 'Demon Reaper'~?]
"Tch, too edgy."
[Aww, but I wanna name stuff~!]
Ignoring her pouting tone, he moved on to his next purchase.
Unlocking His Hidden Power
Dev popped the 'Dormant Quirk Awakening Pill' into his mouth, and heat exploded through his body. His muscles tensed. A strange pulse of energy ran through him, making his skin tingle. Then—
[Hidden Quest Completed: "Unlock Your Hidden Quirk"!]
["Rewards"]:
[1. Elemental Body (Adaptive)
[2. 1 OP(Origin Points) per hour (Passive Income!)]
[3.10,000,000 Yen]
Dev blinked. "...Wait..Hidden Quest?..Elemental Body?!"
[Yep! Congrats!]
"But my parents were quirkless! How the hell do I have a hidden quirk?!"
[Oh, Dev~ You naive little thing. Do you really think 'quirkless' means 'no quirk at all'?]
"Uh, yeah? That's literally what it means."
[Nope! Wrong! Every being has a hidden quirk! But most never awaken it. It requires specific conditions—like extreme stress, external energy, or emotional triggers. Your parents never activated theirs, so they appeared quirkless.]
His eyes widened. "Wait… does that mean most quirkless people actually have hidden quirks?!"
[Bingo~! But no one knows because they never trigger them~]
Dev's fingers twitched.
"So… if I didn't have this system, I would've gone my whole life believing I was quirkless?"
[Mhm~! Kinda tragic, huh? But lucky you~! Now you have Elemental Body!]
"...Okay, explain my quirk."
[Simple! Your body can adapt to elements through training! Right now, it's neutral, but if you expose yourself to fire, water, lightning—your body will start to develop elemental affinities~!]
A slow grin stretched across Dev's face.
"So… I can train and eventually use fire, water, lightning, or even stuff like magma and plasma?!"
[Yup~! The more you push your body, the stronger it gets!]
Dev let out a low chuckle.
"I. Am. So broken."
Enhancing His Quirk
Now that his quirk was awakened, it was time to boost it.
He grabbed the Quirk Enhancement Pill and swallowed it without hesitation.
Instantly, a shockwave of power burst through his body. He clenched his fists as pure energy surged through his veins. His Elemental Body felt like it had just been supercharged.
[Quirk Enhancement Successful!]
[Elemental Body Upgraded: Faster Adaptation, Increased Energy Capacity, and Higher Elemental Affinity!]
Dev exhaled, his breath crackling with faint sparks of energy. His whole body felt lighter yet stronger.
"Heh… this is getting ridiculous."
The Hesitation Before the Clone Technique
His gaze returned to the Multi-Shadow Clone Technique in the shop.
"Wait… this thing needs chakra, right?"
He hesitated. He didn't have chakra, and Naruto's world ran on a completely different energy system. Wouldn't this be a waste?
[Ohh~! You sweet summer child~]
Dev narrowed his eyes. "...What?"
[Who told you that you can't use other energy systems?]
"...Because that's how different worlds work?"
[Normally, yes~! But~! When you fused with the Modified Kryptonian Bloodline, all your biological defects were erased! Your body became the perfect host for any energy!]
Dev's eyes widened. "Wait… what?"
[That's right! You don't have 'chakra' like a Naruto native, but all skills, techniques, and weapons from different worlds will automatically convert to your own Cosmic Energy! Meaning—]
Dev grinned. "I can use everything?!"
[Bingo~!]
Without hesitation, he hit BUY.
[Purchase Complete! Multi-Shadow Clone Technique Acquired!]
Excited, he flashed through the hand signs.
"Shadow Clone Jutsu!"
POOF!
Three clones appeared before him. Each one stared back, mirroring his smirk.
One of them waved. "Yo."
Dev burst out laughing. "This is insane."
[Insanely useful~ You can train multiple things at once!]
He nodded. "Alright, one of you—punch me."
His clone grinned. "With pleasure."
BAM!
Dev staggered back. "Ow! Shit!"
The clone cracked its knuckles. "Damn, that felt good."
"...I regret everything."
[Ehehe~ You asked for it~]
"..well anyway it's just awesome"
———————————-------------------------
Now that he had a quirk, Kryptonian bloodline, and OP gear, a thought sparked in his mind.
'This world is filled with villains. Heroes are restricted by laws and red tape. But me? I don't need a license to help people.'
His grip tightened. He had power. Power he refused to waste.
[Eve, how much does it cost to upgrade the Time-Space Training Room?]
[Depends on the ratio increase. You wanna boost it to 1:3? That'll be 200 OP!]
"I'll hold off for now. First, let's test out what I have."
That night, Dev put on his black suit and stepped out into the city.
He wasn't a hero.
Not yet.
But the people needed someone.
A shadow in the night.
A demon for criminals.
And soon, the world would know him as—
The Knight Demon.
