Low-Fantasy Occultist Isekai

"Hold still," Nick muttered, planting a knee on the spirit's heaving chest. "You're going to die either way, but at least do so with some dignity." Crazed spirits didn't often receive goodbye ceremonies or peaceful sendoffs anyway. At least this one would be useful even after passing on.

He drew his ritual dagger again and sliced a shallow seam from sternum to throat. Instead of blood, liquid moonlight poured across silver fur. The spirit howled, its jaws snapping at him even now, yet the chains held, and whatever fire it conjured continued to be funneled away, only strengthening the ritual. "What a mad creature. It's surprising you could keep up a facade for so long."

I should have known when it revealed it was over a century old, yet it only had one tail. Only a fox-spirit that invested the majority of its power into a grudge or obsession to prevent fading wouldn't have gained at least a second one.

Half-solid ribs parted under a second cut, revealing a palm-sized ofuda—a glowing talisman— sealed to what passed for the creature's heart. The parchment looked impossibly fresh—its edges crisp, and its charcoal strokes unmarred by a century of rot. Thin cords of vermilion thread stitched it directly to metaphysical muscle.

That's a powerful anchor, Nick noted. Someone talented—and obsessive—made it. I have no idea how to do something like this, but I can tell it took them a long time.

He pressed two fingers to the parchment. A cold pulse rippled through his channels, allowing him to sense its inner workings; the woven knots of power were exquisite, each stroke a miniature array harmonized to the next.

Despite being unable to read the angular script—something halfway between classical kanji and a shorthand unknown to him—Nick could feel the semantic current, the meaning it was imbued with: Defend until the land is safe. Simple. Brutal. Open-ended. No expiry clause—no wonder the fox had rotted in its duty.

"And with the temple wrecked, 'safe' meant kidnapping the first candidate suitable for restoration it could find," he whispered.

The spirit snapped again, more plaintive than feral. Its luminous eyes flickered between hatred and pleading, as though begging him to remove the tag, yet terrified of death. A hint of understanding glimmered, revealing that it knew its actions hadn't been righteous.

Nick's grin showed no sympathy. "You'd have devoured Elia's life for a ridiculous purpose. But your crafter… they interest me."

This is very similar to shikigami creation in essence, but it is also very distinct. I wonder… Yes, I should be able to get it to release without breaking the script if I just counter its purpose for a moment.

While the spirit fox wasn't the most powerful foe Nick had faced, the ofuda had certainly been created by someone much stronger than he. Although that meant he couldn't overpower it, it was so old, and its purpose was so distorted that a simple interruption should allow the spirit to die.

He set a thumb upon the paper, pushing thoughts of freedom, of finally resting, and peacefulness into it. His blood smeared the parchment, and the ink convulsed, misaligning the mana knots for an instant. The fox gave one last, warbling yip before its torso detonated into motes of argent flame.

Chains cinched inward, crushing the collapsing form he had hollowed out. Silver sparks spiraled into the ritual lines, followed by thicker streams of pink-white essence. Nick's circle drank greedily, routing every strand toward the focus lines beneath his boots, then through his feet, up his legs, exploding through his coils.

He sucked in a breath as liquid power hit his core. There was no gentle diffusion; the spirit's nature—cunning, swift, foxfire-bright—slammed against his soul. It could have torn him apart if he had been less prepared for a last-minute attempt.

But he had known to expect this. The fox might have been mad, but there had been an underlying logic to it, and it would have surprised him if it had gone down without trying to attack when he should have been distracted.

Protecting himself from the onslaught didn't take the form of a shield this time. That would have wasted all that sweet, spiritual mana, and he had plans for it. Instead, Nick activated [Vitality Drain] just as it exploded, and all that power was quickly absorbed, leaving him with a chaotic mess where the spirit's mind had once kept everything together.

But within that chaos floated the cold logic of the ofuda itself: precise strokes, binding architectures, conditional nodes—all the craftsmanship, now ownerless, tumbled into his mind like puzzle pieces seeking a new frame. Nick caught them, bent them, and welded them onto his own spell, watching it change.

[Minor Shikigami]—his clumsy paper-familiar cantrip—buckled, broke, and re-knit. Lines spread outward, weaving into a much broader diagram like black brush strokes unfurling across invisible silk.
