The Power Of Two

Kai found himself, in a world filled with red. The Sky, the setting dusk, even the sand beneath him. All of it was red, apart from the purple gate in the sky which was decorated with two golden skeletons.

He fell onto the floor with his knees, before screaming into the sky. As he cried, the world grew more chaotic. The earth began to break apart as rivers of lava spewed out. Large masses of land started to rise, defying gravity.

"Why do you cry? Why do you rage?"

Kai looked in front of him, and saw that same shadow figure as he had scene once before. But unlike before, that shadow veil had at last come undone.

She was a tall and slim young woman with long, straight black hair that has an uneven fringe and crimson red eyes. She wore a black wedding dress, with a thin veil that would sometimes cover her face, but would occasionally be blown off slightly by the strong wind.

"Oh!? So you can see me this time."

Kai slammed his fist into the ground, creating a small miniature crater.

"I was too weak! SO SO WEAK! I finally made my mind up about saving someone, I finally worked up the courage to fight... and it all went down the drain. I just wanted to save her, but I got saved instead."

"And now she's dead because of you."

Kai's sobbing slowed down, but he still felt as if there was nothing that he could do. Avenge her death? Was he even strong enough to do that?

"So what will you do now? Do you want revenge? Do you want to run away? I will do anything for you."

"I want to kill him myself." 

Her veil hid away her sly smile. Even if the intentions are questionable, she had a strange unbound loyalty towards Kai. She got down and began to hug him, with a warmth that Kai had never felt before even from his own mother.

"I don't care if you want to kill innocents, I don't care if you want to destroy this world, I will do anything for you. And that's because your a King."

Akimitsu tried to wipe off the clumps of flesh which remained on his gauntlet. Even if he was a murderer he was still sanitary about the corpses. He looked up towards the sky, and realized that Liliane gave one last fuck you to him before she left.

This space was supported by her Fullbring which she copied from Yukio Hans Vorarlberna in very unlikely circumstances. After gaining this ability, she could create sub dimensions which she was effectively a god inside. The condition for this sub dimension to be broken required for only one person to be left inside.

"Ah- More work for me I guess. She really is too irritating. Perhaps I'll feel something if I-"

He Suddenly felt a Spiritual Pressure that was utterly horrifying behind him. He backed away, while keeping his eyes locked on to Kai who was emitting that strange power.

It was fluctuating constantly, sometimes it would surpass him, and others it would be weaker than his own, but if there was one thing he was sure of it was that he was in great danger.

As Kai rose back up, he held his broken Asauchi which started to emit its own spiritual pressure. And then suddenly, the broken fragments which laid next to Linny's corpse flew towards him.

His sword repaired itself before flashing with a blue light. He put both of his hands inside it, and split the sword in two, transforming it into a dual wield Zanpakutō.

"One of the blades, are shorter than the other?", Akimitsu said in confusion.

Before he could even react, Kai accelerated to the point that he disappeared in the air. Suddenly a cut stretched across Akimitsu's cheek, as Kai then crashed into the grass right behind him.

Nervously, Akimitsu turned around only to see the blood lusted boy with a red liquid lining the smaller Katana.

Kai then disappeared once again, and so Akimitsu raised both his gauntlets up to defend. Sparks and sound of iron clashing against each other could be heard as Kai's Zanpakutō constantly tested his defence.

Akimitsu took a step back to try get some more room to breath, but Kai kept releasing a barrage of unrefined sword slashes that forced him on the defensive.

In this moment Kai was more like a raging beast than a Shinigami, but unlike before where he would get sudden boosts in power from within himself, he was in complete control of his actions.

As he fought he heard the voice of his benefactor whisper into his ear as he fought.

"I can't summon the Jigoku Shihakushō again, however I can use some of its power to modify your body."

Kai used flash step, and teleported behind Akimitsu. In response he quickly turned around to block the on coming assault but instead threw a punch. His fist went through Kai's head, only to see it was an afterimage.

By leaving behind extra steps in his flash step, Kai could leave behind an after image to confuse panicked opponents. The real Kai had already returned back to his prior position, and then he slashed Akimitsu in the back.

As he bled, Akimitsu tried to punch the Kai once again, only for him to disappear just as quickly.

"I've made you physically strong enough to use flash step, and I boosted your spiritual pressure enough to beat this guy. If you exert too much strength then your own power will devour you."

Kai then suddenly coughed up blood which stunned him for a bit. Using the opportunity, Akimitsu right hooked him in a punch, before carrying out a three hit combo.

By the third hit, Kai moved his forehead to block it, and then slashed Akimitsu with the longer Zanpakutō in his right hand across the torso.

It felt as if his own body was rebelling against him, but he pushed on anyway.

Akimitsu knew that Kai wouldn't be able win a drawn out battle, which his ability was perfect for. But even then he felt a strange urge to show this opponent his best.

As he laughed, Akimitsu used bringer light to jump high into the air and aimed both of his fists at Kai who was immobile.

He released all of his Lieutenant class Spiritual Pressure plus more as he stated,

"MY FULLBRING, REVOLUTION, INCREASES MY OWN SPIRITUAL PRESSURE THE MORE DAMAGED I BECOME! IT'S A FULBLRING THAT REWARDS PUNISHMENT! I'LL BLAST YOU AWAY WITH ALL THE DAMAGE WHICH YOU HAVE DONE TO ME THUS FAR!"

An orb of red Reiatsu began to gather around at the end of his arms along with sparks of black electricity.

"BLACK STAR CANNON!"

A huge laser of red and black Reiatsu was then fired at Kai, with power threatening to evaporate a mountain. Even with this calamity charging towards him, Kai didn't back down.

Instead he rushed towards the Reiatsu as he began to release his own. The two collided with equal strength which caused the land around them to be swept up and away, even Linny's dead body was long forgotten as that too was destroyed.

Once the impact from the attacks ended, a large dust cloud formed which engulfed Akimitsu who fell back onto the earth.

The lush green field was destroyed, and only the brown earth was left.

He heavily breathed as he tried to regain his strength, surely that attack killed him.

"That idiot went into the attack. If that didn't kill him then nothing I have could-"

A small blade pierced into his back as its tip become visible on the other side. It then tore through his heart, lungs, and ribcage before exiting out of his right shoulder.

A river of blood spewed out the gaping wound in his body, as he then collapsed onto his paralyzed back. He looked up and saw the heavily injured Kai Kureno standing above him.

"Were you satisfied with that? Did that fill your emptiness?"

Akimitsu Chuckled before the light inside his eyes finally faded away. He couldn't give a response before he died, but the answer to that question would remain with him even in hell.
