The moment I closed my eyes, I fell inward.
Not into sleep. Not into dreams. Into something deeper.
When I opened them again, I stood in a place that stole the breath from my lungs: a colossal library that stretched beyond infinity. Towering shelves spiraled into the heavens, filled with grimoires, scrolls, tablets, and artifacts glowing with magic from a thousand worlds. The very air buzzed with knowledge, heavy and intoxicating.
"My library…" I whispered, tears stinging my eyes. "It's real. It's all real."
Every book here was mine. Every spell, every theory, every secret. It was enough to make my otaku heart scream with joy.
As if answering my unspoken wish, a doorway shimmered open to the side. Beyond it lay a vast hall of white stone and shifting energy—my training room. A place where I could practice, experiment, even duel constructs of my own making.
"This is… heaven," I muttered, stepping forward. "Anime fangirls everywhere would kill for this."
But I wasn't here to gawk. I was here to become what I asked for: the greatest magical genius in the multiverse.
Month One: The Basics
I started simple, because even geniuses need foundations.
From the Harry Potter section, I absorbed the structure of wand-based magic: charms, transfiguration, defensive spells. Lumos, Expelliarmus, Protego—child's play now, the mechanics dissected in seconds by my enhanced mind. I didn't even need a wand; I rewrote the casting system to channel directly through my mana.
From The Wandering Witch, I studied travel and utility magic. Flight, cloaking, alchemy. Elaina's graceful spells now flowed from my fingertips with ease.
From the Marvel archives, I traced the lines of sorcery that Doctor Strange himself wielded. The Vishanti. The Crimson Bands of Cyttorak. Eldritch shields that flared like golden suns when I raised my hands. The spells were complex, layered in contracts with cosmic beings, but my mind tore through them, analyzing, refining, perfecting.
And every night, when exhaustion threatened to creep in, the endless mana within me surged, burning fatigue away. I was unstoppable.
Month Two: Expanding Horizons
Now I wanted versatility. Power. The kind of spells that made armies tremble.
From the Fate Universe, I devoured magecraft. Reinforcement. Structural Analysis. Bounded Fields. But what fascinated me most were the Noble Phantasms. Artifacts woven from legend, crystallized concepts of power. I couldn't wield one yet, but I understood the principle. I could create my own.
From Jujutsu Kaisen, I practiced Cursed Energy. Domain Expansion was… complicated. But I adapted it, blending it with Marvel wards to create my own pocket-realm of control.
From Mushoku Tensei, I memorized chantless casting, layers of elemental manipulation, spells that split mountains. My control sharpened to a razor's edge.
Every day, I sparred with conjured opponents in the training hall. My spells flowed faster, sharper, more creative. Fire and ice, light and shadow, raw arcane force and delicate enchantments—weaving them together came as naturally as breathing.
Month Three: Proof of Genius
By now, the library felt like home. My mind was a storm of spells, formulas, theories, innovations.
I cast a Protego shield while layering Marvel Eldritch Runes over it, making it impenetrable to both physical and magical assault.I conjured a bounded field from Fate, stitched with Harry Potter's protective wards, amplified by Elaina's travel runes, making it both a fortress and a sanctuary.I combined Jujutsu's Cursed Energy manipulation with Marvel's Crimson Bands, binding my opponent so tightly that even gods would have to struggle.
And the best part? I wasn't just learning these systems. I was rewriting them. Simplifying complex rituals. Strengthening weak points. Blending them together into something entirely new—my own personal sorcery.
Because that was what it meant to be a genius. Not just to memorize, but to innovate.
When I finally opened my eyes and returned to the grassy plain, the sun was still high in the sky. Not a second had passed outside.
I smiled, standing, the witch's robe swirling around me as my silver hair shimmered in the light.
"I did it," I whispered. "I really am the greatest magical genius."
And somewhere deep inside, I knew this was only the beginning.
