The Senkaimon led Zenshin to the right place, just outside Las Noches, a massive fortress in the middle of a desert of the Hueco Mundo. He had left everything behind in exchange for his survival, his status as captain, his friends, and anything close to family. If he didn't, the captain-commander would've eventually find out and order for his execution for treason, Zen had no choice. Zenshin came to the only place he was sure could help him control this, the hollow world itself. Looking up, he saw and admired the massive fortress that was Hueco Mundo, it was so big it was scary.

As he walked towards the entrance, he felt a strong spiritual pressure coming his way, it seems his Senkaimon had attracted some attention. Maybe this Arrancar, as Zenshin assumed since it was a spiritual pressure stronger than him, an ex-captain, could help him control his hollow. But then, he felt it taking over, and threw his hand over his face as the mask materialized.

Arekussu felt hunger for the first time in weeks. His body ached for blood, the beast stiring his adrenal glands and egging him to great destruction. Arekussu was not inclined to follow the orders, but he had not allowed the beast his bloodlust for a long while and he was impatient. Every few weeks Arekussu would go into the sands and feast on hundreds of hollow, allowing the beast control for this short period to keep him at bay. For the past month, however, he had been too busy with his duties to go hunting.

Convieniently, a report had come through of a senkaimon just outside of Los Noches, and Arekussu had jumped on the opportunity to allow the beast his respite. Resssspite. You treat meee like ssssome disssssease Kussu. Arekussu shook his head, clearing his mind of the beasts thoughts before replying. Disease? More like curse. Jusssssst let me feeeeed Kussu. I am ssssso hungryyyy. Arekussu continued to Sonido towards the Senkaimon as he spoke to the beast, not letting all of his conciousness over to the monster until he had gotten his point across.

The thoughts of the Beast sounded horrible in Arekussu’s brain, but he was only plagued with them on days like this where the Beast had not been fed for a long time. He was good at controlling the beast after all this time, but there were days where he had to come out, and he could feel the power creeping from his limbs as he thought about this. With a sigh, he relinquished control of his body to the beast, sending one last thought his way, Don’t kill them, I need to talk to them when you are done. He knew that the beast would comply, this time anyways. He never really knew what the beast would do for sure, but the way the beast was acting seemed almost playful rather than angry, in some twisted way.

“Time to FEED!” Screamed the beast as his features stretched and shifted, making his mouth reach from ear to ear and his eyes stretch to the side of his face. His pupils were clouded with blood red and his tongue stretched to almost 2 feet long making any further conversation impossible.

He tasted the air and smelled a vizard… or was it a hollow? It didn’t matter, it was food. The Beast sonidoed directly at the source to see a man covering his face with his hand, white fluid seeping between his fingers and beginning to cover his body. Arekussu knew what that was, that the man was going into hollow form and probably had never gained control of his inner hollow, but the Beast didn’t care. He raised his fist, charging a cero in his palm, and sonidoed directly at the man, his fist flying towards his face. On contact the cero would explode sending a huge blast of energy towards the man.

-----

Arekussu cringed from behind the Beasts mask. He wasn’t sure, but an attack like that could probably kill the man if he didn’t go into hollow form fast enough to block it. Hopefully the man knew what he was supposed to do to fight his hollow.

"You cant keep me in here forever. Forever. Forever. I will get out now, and you won't be able to stop me. Me. Me. Give me control NOW! NOW! NOW! Zenshin's hollow's words echoed through his head every time it finished a sentence, Zen was losing control of himself and quickly, he was about to lose it. Grabbing his head tightly with both hands, he dropped to his knees yelling, "Get out! Get out of, my- my head right now! Get out!". Zen never lost his cool like this, his hollow side was pushing him to the edge of the abyss and was not easing up a bit. The mask began to form, the teeth on it sharper than most masks and a long black line down the middle, and before he knew it, his hollow was in control. He didn't like it, but the mask saved him, another masked man had thrown a punch with such speed and strength that it might've killed it had it not been for his hollow mask.

Zenshin had been able to get out of the punches way with the speed increase that his hollow bestowed. "Finally in control, and I'm never letting go, you can kiss your body goodbye, Zenshin." said his hollow aloud, making sure that Zen heard him. "Lookie what he got here, my first kill? You should feel honored, beast. You're the first one I kill with my new body, hmm, I don't feel that filthy soul reaper Riatsu on you, just hollow. No matter. I'll kill you, and every last hollow in this place". The hollow wasn't in complete control, his movements locking up slightly, but Zen could regain control after, as this enemy required him to be a hollow.

Zen gave almost all control to his hollow, leaving him with slight control to give himself a starting point after the battle. Carack, as the hollow said his name to be, raised his arm up and said "Bakudo 62, get that glowing hand away from me."and threw a glowing pillar, that dissipated into smaller pillars that would pin the mysterious enemy upon impact to Las Noches wall if it succeeded.

The Beast screamed in anger as the man dodged his attack. The cero remained in his palm as he turned to face the hollow. He was so hungry. Just a little bite, a little snack. He licked his lips as the hollow spoke to him, but the Beast was beyond understanding words at this point. He did understand, however, when the man lifted his arm and sent pillars of reitsu flying his way. The Beast lifted his arm and screamed,his fignernail cutting his skin and let blood drip into the cero, transforming the energy into a Gran Rey Cero. He then let the cero in his palm release and send a gigantic wave of energy blasting at the hollow. The energy easily overpowered the bakudo and disintegrated it and continued to fly at the hollow.

The beast sonidoed the instant after firing the Gran ReyCero, moving easily faster than the ball of energy could thanks to his increased speed from his music and appearing behind the man, his whole body already spinning from the force of the sonido and adding incredible power into the kick that he sent at the man’s head. Considering the difference in speed between the two fighters this attack would almost certainly connect, or at least force him to block. And with the Cero still coming their way they would both be enveloped in the blast.

Once his foot connected, Arekussu would turn his body and send his right hand into the man’s thigh, using the extended nails form Beast form and his strong hierro to attempt to pierce through the hollows white armor and into the flesh underneath. If he couldn’t hit there he would follow through on the kick with all his strength by putting both hands on the ground and forcing the hollow onto his knees, further making it impossibly to dodge the cero.

As one final measure, the Beast had, during the sonido to the hollow, released over 30 Bala in all the possible escape directions around the edges of the cero, so that even if by some impossible chance the hollow did dodge Arkussu at his full speed he would still be struck by a bala and probably fall into the Cero anyways.

Of course this whole plan meant that the Beast would be struck by his own Cero, but thanks to his tough Hierro he would take minimal damage form the blast, probably just a few burns. However judging by the hollow’s spiritual pressure the blast will do a lot more to him than it would to the Beast.

-----

Arekussu would have face palmed if he could have. The Beast was such a suicidal fighter it made him cringe. He remembered a long time ago the beast had even taken a zanpacto through his own stomach so that he could disarm his opponent. It looked as though Arekussu would need to do some healing after this fight no matter what.
