Epic of Caterpillar

With six seconds left, Kireina finally arrived at her objective, the connection between the Genie's Phantasmal Soul and the Souls of the Ruler of the Necrotic Plane and the Ruler of the Maxima Universe.

"You're too bold." Laughed the Ruler of the Necrotic Plane. "Do you truly believe you'll be able to damage us? These are merely the manifestations of our prowess!"

"If you truly think you can hurt us somehow, you're sorely mistaken!" Laughed the Maxima Ruler. "Pointlessly fight as much as you want, you will eventually perish by my hands, you-"

"Silence." Kireina said, her closed eyes instantly opened, flashes of rainbow light and darkness emerged from them, her entire body channeling every last bit of power she held.

Bifrost moved without moving, and pierced both of them without even piercing them, the effect emerged without the cause! The divine power of Bifrost was finally showcased on its full potential as the slashing blows reached the souls of the two Rulers together at once, an utterly impossible feat all across the vast Cosmos!

SLAAAASH! SLAAAASH!

Both slashes reached their very souls, damaging them directly, just as they have never expected to happen! Looking down on Kireina was something they could never allow themselves to do now, as they saw her true, frightening prowess!

"G-Gaaaaggh…! M-My soul has been damaged?!" The Ruler groaned from within his own Dimension. "N-No… What is this?!" He glanced at his very soul, seeing countless slashing wounds covered on rainbow light, consuming his powers, and then adding them back to Kireina!

"I-I need to pull back! How come… she can do this?! This is utterly impossible!" He panicked, quickly deciding to pull back his strength and powers from manifesting within the Genie.

"You may run away for now, but it will cost you!" Laughed Kireina, her blade emerged in the very Necrotic Plane, surging out of the soul and body of the Necrotic Plane Ruler, his countless eyes knew true fear once more!

"GRUUAAAGGHHH…! S-STOP! STOP I SAID!!!" The Ruler screamed in agony, as he was forced to tear apart a piece of his soul before finally freeing himself from Kireina's powers.

SLAAAAAAAASSSHHHH!!!

"GRYYYAAAAAAAHHHHHHHHH…!"

His monstrous, eldritch scream echoed across his entire Necrotic Plane, all of his servants, all of the Undead, all beings that existed within this Plane, this pseudo dimension, were utterly shocked as they heard the screaming voice of their supreme ruler!

However, comparing the Ruler of the Necrotic Plane to the Maxima Ruler, he got out rather easily… Because within the Maxima Universe, as he desperately tried to draw back his soul and powers from the Genie…

"Where do you think you're going, old man~?" Kireina's voice echoed from within his very soul, as her blade pierced through his soul, slashing it away countless times.

Defying the ranks between the two of them, defying concepts themselves, and bringing an effect without cause! Bifrost's powers manifested on its utmost strength as they merged with Ouroboros and the Trait of Defiance, in just these last three seconds…

The end of the Maxima Ruler came, like the blink of an eye!

"N-No…! My body… my soul…! T-This is impossible! Impossible! IMPOSSIBLEEEEEE!!!" He screamed in agony, his very soul was being consumed, devoured!

Kireina started to gain a tremendous amount of power, as the entirety of the Maxima Universe started shaking in horror! All gazes set into their supreme leader were filled with shock and awe, completely bewildered as they saw their very supreme ruler being defiled, killed in front of them!

"N-No…! [Universal Chains]!!! [Universal Dao of Maxima Summons]! D-Don't…! UGGH…!"

Countless powers and authorities attacked Kireina's powers all at once, but they were instantly destroyed into ashes against the ultimate power to defile concepts themselves! Everything was pointless, and anybody that tried to help him was immediately cut down into countless pieces by thousands of slashing, rainbow-colored attacks.

"S-Stop…! STOOOOP!" The Maxima Ruler screamed, as he suddenly began crying in frustration, all of his Empire, all of his power… it all meant nothing!

"You should had never messed with me." Kireina said, plain and simple. "Now, this better be a good message for all of those bastards that want me dead! I'll receive you with OPEN arms!"

The Maxima Ruler's very shadows transformed into the face of Kireina, her glowing red eyes glaring at all the Ruler's children, grandchildren, and his entire Empire…

"N-No…! D-Do something…! DO… SOMETHING! Y-YOU USELESS… PIECES OF GARBAGE!!!"

In horror, his descendants saw their ruler turn into ashes completely… they were too afraid of even touching him, as all those bold enough to step and help him died instantly. The entire Maxima Universe suffered the death of their King in just the blink of an eye, and with mostly none of them knowing how, or why…

RUMBLE!

The entire Maxima Universe trembled, countless cracks continued spreading across the entire Universe as it started to distort, a gigantic black hole began appearing on the Universe's center… without a Ruler, a Primordial that worked as the Universe's Pillar, the death of the whole Universe was near!

"N-No… this can't be happening…"

"W-What have you done?!"

"Our Ruler… Who did he provoke within this vast cosmos?!"

"Someone capable of killing him… Someone beyond our own comprehension…"

"R-Run… RUN AWAY!"

The strongest beings within the Maxima Universe panicked as their Universe started to slowly distort, soon it will perish completely.

However…

"W-Wait…"

"Eh?!"

"W-What's that?"

"Who is she?"

Suddenly, several glares reached the center of the Universe once more, as the emptied throne of the Ruler of the Maxima Universe was once more taken… someone with an equal level of power was sitting there, smiling devilishly, her butterfly-like wings spreading across the Universe.

In awe they glanced, the Universe was restructured and it quickly regained its stability, slowly going back to its former appearance… of course, with someone very important missing, now replaced by the very one that felled him.

"Fufufu~ Oh my, did you thought the Universe would end? My bad! It was so funny to prank you all!" Laughed the entity, her red eyes shining like crimson stars across the Universe.
