Epic of Caterpillar

Scarlet was confused, she didn't know what happened at all. In a single second they had triumphed. The little girl thought they would get some time to rest, to enjoy a meal with family and be happy together. She just wanted things to go back to how they used to be, where she could spend days after days with her mothers and be happy. To go on carefree adventures with her sibling. And to finish every day having a feast together.

But since her mother's death, and even after her return, there has been little time to rest. Battle after battle, constantly bloodshed and struggles. Kireina told her she didn't need to help, that she could stay insider her World Realm. But little Scarlet thought that would have been too much. She had to show she was strong and that she could help her mother as well. That she could do something for everyone. Even if little…

And through this fight she truly thought she was helping. She did. But while doing so, her powers developed. And something strange surged within her, a Dao she had never seen before, the "Dao of Blood Dimensions", was born as she absorbed the Divinity Fragments of the Soldiers of Oceanus.

She only thought of it as some sort of new power, nothing else, nothing more. However, its true power and true purpose resurfaced once this event happened. Once she felt the claws of the Outer Gods grab her across Reality and imbue her with the power of the Abyss Gate Fragment.

Her Dao instantly reacted, as she felt incredible pain coursing through her body. Crimson lightning constantly trying to burn her. She tried to ask for help, she really did. She tried to even devour this power, but it didn't work. For the first time her powers were not working against them. And it made her see herself as a weak girl, that shouldn't have stepped into this battlefield.

"Uuuggh…! Aaarrghh!"

"Scarlet!"

"Sis?!"

"What's going on?!"

Gaby and her children instantly tried to go help her. Alice and Alucard rushed to her aid as well, but Scarlet, as she screamed and cried, tried to stop them from drawing closer to her. She didn't want them to be victims of the same claws grasping her Soul and Origin.

"No… D-Don't get near me…! AAARGH!"

TRUUUMMM…!!

A shockwave of crimson lightning erupted from her body. Everyone was blown away several hundreds of meters the moment they were hit by it. The barrier Kireina created blocked the attack before shattering, and Scarlet's own barrier had broken already. A black portal opened, beaming her with this dark crimson light a second ago, making her surge with this corrupted power.

"SCARLET!"

Kireina screamed from above the skies, moving down as fast as she could while being constantly stopped by countless Outer Portals opening, Minor Outer Gods attacking her left and right, stopping her from reaching her daughter. She saw the two other Fragments of Abyss find Scarlet, fusing with her chest. The girl screamed painfully as they merged with her. All three fragments became one as they gathered inside of her Origin, the Dao of Blood Dimensions further improving their combination.

"Ma…ma…"

While tears streamed from her ruby-like eyes, Scarlet's chest opened monstrously, revealing a black and crimson portal, swirling endlessly, and constantly expanding. Her little form completely changing, as she turned into her "true form", a shape not even Kireina nor Scarlet knew she had, resembling a gigantic crimson snake and centipede hybrid.

"Scarlet…! No!"

The monstrosity she transformed into swiftly coiled around itself, biting its own tail. The portal expanded inside of her coiled body, constantly searing and slicing through the Dimensional Walls of the Spiritual Plane. Gigantic crimson and dark cracks opened across the entire Plane.

The inhabitants, Ruler, and all other beings within the Spiritual Plane all felt the commotion. The gigantic cracks that opened all across poured a sea of corrupted black blood everywhere, contaminating the skies and transforming them into an eternal night, which spread across the rainbow skies.

The scent of blood covered everything. Billions of innocent Spiritians ran away from their villages, seeing the cracks expand above their houses as rains of black blood corrupted everything. Vampiric and darkness essence trying to transform this bountiful dimension into one of eternal nightmares and bloodshed.

"NOOOO!"

Kireina roared with utmost fury, her entire body fusing with all her powers, harnessing everything within her own arsenal, her path jewels, even her own World Domain. She harnessed the power of the Maxima Universe, fused with her Swarm of Monsters and Undead, turning into a gigantic cosmic spear that pierced through all things. The Minor Outer Gods were unable to stop her anymore! She burned through her Cosmic Energy at a staggering speed, but if it was for her daughter, she would even give up her own life.

"RAAAAAHHH!"

With a furious roar, the titanic cosmic spear she had turned into reached Scarlet, the portal only became wider as she grew closer, it broke into several cracks that generated smaller portals, hundreds of them. The Outer Portals connected to them, as the Minor Outer Gods and Three Gigantic beings Kireina could not comprehend entered through it, going to the other side.

To Abyss!

"Is this all for that?! You did it all to get to that damn kid Noah? You bastards?!" Kireina landed on Scarlet, crimson lightning and darkness shrouding her entire body. She was beginning to fall into pieces, disintegrated by Scarlet's own powers. But she kept regenerating. "Scarlet! Don't worry, mama is here! Your mother will not let you alone!"

"Ma… MA…! AAARRGH…! RAAAAARRRGGHH!"

However, Scarlet could not take it anymore. Her mind faded away, falling into utter madness and darkness. No longer was she her adorable princess, but a mad, abominable monstrosity attacking Kireina, trying to devour her and tear her apart. The portal only became larger, until it was so gigantic it created a suction force, the gravity of Abyss dragging everything within the Spiritual Plane inside.

Kireina tried everything she could to heal Scarlet, to make her change. She tried dispelling this power, but she was unable to fight it. And every time she touched it, she her hands would be instantly disintegrated.

At the end, Scarlet herself was dragged into the portal, with Kireina, and everyone else.
