Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 439 So That's Where My Magic Talent Lies

Looking at the yellowed parchment, the bird felt dizzy.

He casually tossed the heavy ancient book onto the long table in front of him and let out a long sigh.

"...Do you think that old man did it on purpose, showing me these scribbles but not giving me any magical tools to translate them?" Asuka leaned back irritably, her face full of resistance.

Shinobu Kocho smiled, covering her mouth with her hand and chuckled, "This is precious wisdom left by our predecessors; it might hold the answers you're looking for."

As she spoke, she gently pulled the book in front of her.

As the Insect Hashira who once led the medical and toxicological research at the Butterfly Mansion, and having studied in the Fourth Division of Soul Society for decades, she has a broad knowledge of various medical literature from the modern world, far exceeding that of ordinary people.

"Hmm... This isn't just plain Latin; it also contains a lot of early medieval Celtic runes, as well as some alchemical codes used specifically to avoid religious persecution."

Her gaze became focused and serious, her fingers gently tracing the characters: "However, the basic grammatical logic is not completely detached from the current language system; as long as the corresponding word roots are found, it can still be understood."

Looking at Shinobu's focused profile, Asuka felt fortunate to have such a capable assistant by her side, which saved her a lot of trouble.

"Can you understand it?" Asuka asked softly.

"We can probably analyze about 70-80% of it." Shinobu Kocho nodded, pointing to a passage circled in special red ink on the page: "This records how witches in the Middle Ages resonated with the magical power that roamed freely in nature, thereby casting what is known as black magic."

As she quickly browsed the book, she softly translated for Feibiao: "The book says that the spellcaster is merely a bridge of communication, guiding the vast magical power already present in the atmosphere through specific words, syllables, or gestures, shaping it into different forms..."

""

Upon hearing this, the bird seemed to be deep in thought.

"No wonder those two little girls could unleash such powerful moves even though they had so little spiritual energy in their bodies."

In Soul Society, the power of a Kido often depends on the Shinigami's own immense spiritual pressure and their precise control over spiritual particles.

Although I don't want to admit it.

However, it must be said that even if a Shinigami like Aizen abandons the incantation and unleashes his Kido, it is still more powerful than the Kido that many people fully guide, precisely because of the difference in spiritual pressure quality.

This is why Asuka's Kido is so awful... His spiritual power is too violent and filled with a lot of unknown residue, like an untamable beast.

Trying to use such violent spiritual power to weave intricate demonic incantations often results in nothing more than a blown-up chamber.

Shinobu Kocho's fingertips traced across the paper, a hint of surprise flashing in her eyes: "This also contains a very interesting basic magic concept. Would you like to give it a try, Mr. Asuka?"

"Try what?"

"A very basic medieval elemental manipulation spell." Shinobu Kocho looked up.

Asuka paused for a moment, then scoffed, "Don't joke around, Ren... I can even turn the most basic white lightning into fireworks, and you're testing magic here?"

"If we blow up this library, that old man Trompo will definitely fight us to the death."

"It's just a tiny trick that can't even light a match. Even the lowest-ranking witch can do it easily. Even if it fails, there won't be any danger." Without waiting for a reply, Butterfly grabbed Asuka's large hand and placed his palm up on the table.

"Come on, repeat after me."

Looking at Shinobu's expectant eyes, Asuka really couldn't bear to refuse.

He sighed helplessly, resigned to being manipulated by her like a puppet on a string.

"Ignis (fire)..." Shinobu Kocho uttered a single, ancient syllable softly.

"...lgnis." Asuka repeated awkwardly.

He found the sensation of the sound rolling on the tip of his tongue strange, and it felt awkward no matter how he pronounced it.

"Feel the magic in the air around you, let it flow in through your spiritual channels and resonate with you..."

""

Shinobu's voice flowed into Asuka's ears, guiding him to relax his tense nerves.

The bird closed its eyes.

Heeding Shinobu's advice, he completely abandoned the manipulation of the vast spiritual power within his body and instead extended his senses outwards infinitely.

In this ancient grand library, a lingering magic exists like a sleeping ocean.

Suddenly, the bird sensed something was amiss.

When he lowered all his guard and tried to connect with the external magic... he found that the magic did not repel him like the spirits of Soul Society.

Instead, they began to cheer and gather towards his palm!

There was no sense of difficulty or hindrance, nor any violent backlash.

It was a natural progression, a logical and inevitable outcome.

"...What does this feeling feel like?"

The bird suddenly opened its eyes.

boom-!

A loud bang rang out in the quiet book storage area.

Asuka and Shinobu Kocho both stared wide-eyed at Asuka's palm in disbelief.

There, the tiny flame that Shinobu Kocho had described, which couldn't even be lit by a match, did not appear.

A dark purple fireball, about the size of a basketball and radiating terrifying heat, was dancing in the bird's palm!

The purple flame, like a perfectly tamed pet, hovered quietly in the bird's palm, showing no signs of losing control.

It even perfectly contained the temperature of the surrounding air inside, without damaging the parchment on the table.

Asuka looked at the deep, energetic fireball in her hand, then glanced at Shinobu with some suspicion: "This... is this right?"

Shinobu Kocho was also stunned, her eyes filled with shock.

"How is this possible..." She leaned closer in disbelief to examine it closely: "Without any systematic learning, simply reciting a most basic root syllable can unleash such a vast amount of concentrated magic?"

"This level of affinity... it's almost as if the magic of this world is working in your favor!"

To prevent the library from burning down, Asuka gently clenched her fist, and the purple flame dissipated into the air without leaving a trace.

Why is this happening...?

'

He looked at his unharmed hand and fell into a deep silence.

Camilla...

He remembered the name again.

Could it be that I really am, as she said,...?

Over the next few hours, the two of them frantically flipped through one dusty ancient book after another in this dimly lit library area, following the book list.

As the reading progressed...

A vast outline, hidden in the mists of history, that they were unaware of, was slowly unfolding before them.

"Found it!"

After flipping through countless books, Shinobu Kocho suddenly discovered an extremely peculiar mark in a black leather book whose cover had been mostly corroded away.

It was a lifelike hell butterfly drawn with black ink.

"Is this... the mark of death?" Asuka leaned closer.

Butterfly carefully turned the fragile pages and nodded to confirm, "There's no mistake, this must be a note or annotation she left behind."

This book does not record any profound magic formulas, but is an ancient book that is similar to a compilation of local chronicles and myths.

Beside those obscure words, there were dense annotations written in elegant and timeless Eastern cursive script.

That was Tokihime's handwriting.
