Chaos and Order - A Multiverse Fanfic

Kai's pupils trembled, but he said nothing and only gawked at the sight, his thoughts unknown.

The giant Misdreavus fired a massive blue-black ball of energy.

The 100 ft tall Golduck opened its enormous mouth, firing a pillar of water so powerful that it deafened the ears.

Both attacks landed on Red Sun's Shadow Copy, the explosions booming across the Reality Marble.

Suddenly, the colossal, Dementor's black cloak fluttered, and with one sweep, it closed the gap between itself and Red Sun's copy.

It pressed its mouth on the Shadow Creature's mouth and sucked.

The Shadow Creatures possessed no soul, but it didn't matter it seemed, the copy shattering under the might of Dementor's Kiss.

-You are the Sword Spirit,- Kai's hisses came out as a mumble. -But Reality Marbles…-

-Keke! Do you remember what Shinobu had taught you?- the Sword Spirit hissed back.

Dementor-Kai's eyes shone under the dark hood.

-A Demon Slayer's journey is to tap into one's Spiritual Body, awakening both Reiryoku (Spiritual Power) and Reiatsu (Spiritual Pressure),- he remembered Shinobu's teachings, hissing out his words. -That's why Breathing Styles are necessary to become Demon Slayers.

-Not only do they allow the Physical Body to transcend the humane limits but also stimulate the Spiritual Body, allowing the Demon Slayers to sense its presence.

-This stimulation is paramount… for the birth of the Sword Spirit.-

The moment Kai finished his words, his pupils trembled as they had when the Insect Hashira had given out this lesson.

-When the Spiritual Body awakens inside the subconscious world of a Demon Slayer, also called the Inner World, the Sword Spirit takes form,- Kai continued, eying the world-shaking battle of colossal creatures. -This is called Spiritual Awakening.

-A Sword Spirit's power is separate from that of its owner. Some say that a Sword Spirit is… ever present in the Inner World in one form or another, even before the Spiritual Awakening.-

A demonic cackle cut Kai's hisses short.

-Keke! Have you realized, then?- the Sword Spirit hissed carelessly. -In normal circumstances, and with the rate you were mastering Selfless Breathing, you would have NEVER sensed my presence. The Stimulation had just never been enough.

-Yet, the moment you pushed your body beyond the discernible boundary of return, both your Reiryoku and Reiatsu got stimulated, Awakening me.

-I have always been in this world, but I couldn't interact with the outside world; the Reality. The Spiritual Awakening lifted a kind of shackles over the Inner World, granting me vast powers. But…

-I still couldn't bring you here. Neither your Breath nor Mana was enough.-

Kai fell into a rare moment of contemplation.

He looked down and saw that his missing body had already regenerated.

-Sword Spirits can bring their wielders into the Inner World,- Kai hissed, his voice cold and distant. -I never got the Demon Slayer's Nichirin Sword from Verse Fusion Random World. Nor did I have an Asauchi (-the nameless Zanpakutō which all low-class Shinigami wield-) from Bleach World.

-Both are necessary for the Sword Spirit to bring me into the Inner World as per these two worlds.

-I am not Ichigo, the main character, who didn't need these initiator swords because of the hybrid presence of Shinigami, Quincy, and Hollow inside him. But…-

The Sword Spirit broke out in a feat of mocking cackle as Kai reached the end.

However, this laugh was only for Kai, others weren't worthy to hear it.

-But…- the yellow-haired being hissed vilely, -… you are a Contestant. You aren't restricted by the laws of a Timeline. Your Stats assist you as much as they hold you back.

-The concept of the Inner Worlds… is vast enough to surpass Timelines, and it is spread across the Multiverse. I couldn't pull you in, true enough. So, I did the next best thing.-

BOOM!

Golduck's tail shattered the head of a Shadow Creature, and Kai hissed, -You brought yourself out…-

-Keke! Reality Marbles are nothing but a projection of Inner Worlds onto Reality,- the Sword Spirit told Kai, repeating what Meg had taught him, once. -Following the World Egg theory, the actualization of a Reality Marble results from switching the Self of the user with the Real World while keeping the same boundary.

-The size of the Self and the World is switched, enclosing the World in a small container, called Word Egg, while the Self is expanded.-

Kai's eyes narrowed, and once again, he looked over his shoulder, giving the hole in the sky a fleeting look.

-This…- he mumbled back, -… shouldn't have been enough.-

-True,- the black being without a mouth hissed. -Three things made it possible for me to cast this beautiful but grand spell.

-First, I needed a significant amount of power. You couldn't have given it to me, anyway. Yet, the Spiritual Awakening bestowed an even greater strength, and this strength was independent of you and your Stats.

-This also means I can never cast a Reality Marble from my side ever again. This is a once-in-a-lifetime kind of opportunity.-

How could mere Spiritual Awakening grant such vast power to the Sword Spirit? Kai asked the question to himself inwardly.

It was especially so when he could see that this power had already crossed the discernible boundary of the 3rd Set, even scaring Shadow Lord away from them.

What just happened? Kai's heartbeat quickened. What did the Sword Spirit do?

-Second,- the Sword Spirit continued, -your stimulation had originated from Selfless Breathing. The discarding of Self made it easier for me to project your true Self onto Reality.

-This Reality Marble seemed to have no sense of your Self because you were using the Selfless Breathing Style.

-It is abstruse, but you can say that if your Breathing Style had been anything other than that of Selfless, then this casting of Reality Marble would have failed.-

Kai knew what was to follow.

-Third,- he hissed, adding his own brilliance to the Sword Spirit. -The third thing was: Facelessness Second Contrast — the Quintessential Conversion of Inner Selves!-

A sound entered Kai's ears as if the Sword Spirit had licked its lips, an image of a long, snake-like tongue manifesting in his mind.

-Keke! The World constantly attempts to crush the Reality Marbles,- the Sword Spirit hissed, chuckling. -The moment I projected your Self onto Reality, I forced the Reality Marble to discard its Self once again. Otherwise, even with the powers granted by Spiritual Awakening, it wouldn't have been possible to maintain the Reality Marble for so long.

-It's ironic, right? The System allowed us to cast such vast magic, however, none of the three things that made it possible belong to it.-

By now, Kai had calmed down, the anxiety in his heart vanishing bit by bit.

He could see Cersei's transformation had stopped a long time ago.

-You were listening,- Kai hissed, looking to his left, into the eyes of the eyeless being. -You have always been listening.-

-Keke! I quite like that girl, Cersei,- the Sword Spirit cackled.

It took a step forward, almost stepping off the pillar's edge, and outstretched its long hands.

-I know you are wondering why the Spiritual Awakening generated such an absurd amount of Power, right? I also know you must have guessed the answer by now.

-So, what do you think of it? What do you think of the Power that you had thought you would never obtain? Not for a long time.

-What do you think of this Multiverse Interdependency…

-… an Interdependency between Mana and Breath, the Primordial Laws! Kekekekekeke!!!-
