The transition is not a fade; it is a violent, structural tear in the fabric of your perceived reality. One moment, you are standing amidst the hum of modern machinery and the oppressive Cursed Energy of the twentieth century. The next, the world inverted. A sickening, gravitational lurch pulls at your gut, and the neon lights of Tokyo are replaced by a blinding, moonlight-drenched darkness. You hit the earth with the force of a falling star, the impact sending a seismic shockwave through the dirt.

As you stand, the silence of the Taisho-era forest is deafening. The air is unnervingly pure, devoid of the smog and static of the future, yet it feels thin—fragile. It is a world that has never known the weight of a Special Grade Sorcerer. Your Cursed Energy, dense and volatile, reacts to this untouched environment like a drop of oil in a pool of clear water. It surges outward in an involuntary pulse, a physical manifestation of your soul that ripples through the clearing. The ancient cedars groan, their bark splitting under the invisible pressure of your presence, and the local wildlife flees in a panicked frenzy, sensing a predator that defies the natural order of their world.

You look down at your hands. The familiar flicker of your technique is still there, humming beneath your skin with a terrifying readiness. But something is wrong. The "atmosphere" of this era is different. The negative emotions of humanity here are concentrated, focused into singular, predatory entities rather than the ambient curses of your home. You are a walking anomaly, a solar flare in a world of candlelight.

From the deep shadows beyond the wisteria-scented breeze, the "owners" of this forest begin to emerge. They are not Curses. They lack the jagged, chaotic composition of the spirits you usually exorcise. Instead, they are flesh and bone, twisted by a singular, ancient bloodline. Three demons, their eyes glowing with a feral, crimson hunger, creep into the moonlight. Their skin is pale, their movements twitchy and unnatural. They haven't seen a Demon Slayer in weeks, and in their arrogance, they see your modern clothing and lack of a Nichirin blade as a sign of weakness.

"Look at this one," the largest demon rasps, its tongue flickering over serrated teeth. "No sword. No scent of the Corps. Just a strange, heavy smell... like a storm before it breaks."

"I want the heart," another chirps, its body contorting as it prepares to pounce. "The blood smells... dense. High quality. Muzan-sama would be pleased with a find like this."

They have no idea. To them, you are just a meal. They cannot see the Cursed Energy coiling around your limbs like a translucent serpent. They cannot feel the way the temperature is dropping as your power begins to warp the local space. To these creatures, speed is their greatest asset. To you, they are moving through molasses.

The lead demon shrieks, a sound that tears through the quiet night, and launches itself at you. It is a blur of grey flesh and sharpened claws, aiming directly for your throat. It expects a scream. It expects the hot spray of human blood. It does not expect to hit an invisible wall of absolute authority.

You stand at the center of this historical era, a Special Grade disaster that just landed in the middle of a fairy tale. The wind picks up, swirling the dead leaves around your feet in a violent, concentric circle. The forest itself seems to hold its breath, waiting to see how the first Sorcerer in history will respond to the monsters of the night.

You feel the familiar pull of your Cursed Technique. The "Taisho Anomaly" has officially begun. The demons are inches away, their mouths open in a silent, predatory roar.
