Bleach: Cero Devastador

My peaceful days continued and although I was not one to appreciate those, I had no complaints.

Thanks to Kurayami moving in, I had the perfect sparring partner—someone who was way over the weaklings that the Rokungai's underworld scene had to offer. 

Kurayami focused on her training as well. She had chosen a different path but she wasn't necessarily starting from cero. While I trained Mikoto and Sakuya, I watched her meditate constantly with her Zampakutō which had seemingly 'abandoned' after inheriting Shitsutora from Yoruichi. 

She explained that Shitsutora was a legendary artefact of which only four existed and two were known to be located in the Soul Society. One was Shitsutora the relentless white tiger, and the other was the Sokyōku, the Punishment Phoenix. Another one was presumably in Hell and the last one was owned by the Soul King. 

"Ages ago, before the Gotei13 even existed, the Shihōin Clan was tasked to hold onto it and protect it, due to that the Shihōin Clan has had an almost insurmountable status in the Seireitei for a long time. The strongest member of the Shihōin Clan was the one responsible for holding Shitsutora, until now..." She said at the time while sighing. 

Before Yoruichi, it had been their father and then Yoruichi who passed it to Kurayami. And now it was in my hands, So I guess I'm a Shihōin now...

"Before, there didn't exist as many Zampakutōs as there are today. It is said those four artefacts were the original Zampakutō formed from the strong will of four powerful souls until one of the members of the Soul King's royal guard created the Asauchi and therefore, more and more souls were able to become Shinigamis after forming a soul bond with their Asauchi"

"Shitsutora and the Sokyōku were known as legendary weapons that while held by Shinigami, helped protect the living world from a never-ending blur of Hollows where Shinigamis were scarce. Now that the Soul Society is organized, powerful Gotei13 exists and Asauchi are widely available; those ancient weapons have lost their protective role. They're old weapons that are useless as no Shinigami can form a soul bond deep enough to reach Bankai with them, or at least that's what we believed".

"My sister managed to achieve Bankai with Shitsutora. Her Bankai was very strong, but my sister refused to use it for some reason; she even abandoned the Zampakutō and gave it to me when she was exiled. I was not able to repeat her feat, much less even hear Shitsutora's voice"

Before, Kurayami's voice would have been downcast upon confessing this fact. But now, no more. Her tale helped me understand why Shitsutora wanted to be back with Yoruichi, and it also helped me understand that if I managed to achieve Bankai with her, she would have no choice but to stick to me. 

'Good luck, bozzo~' She said to me mockingly. And she was right, it was easier said than done. 

When I wasn't training Mikoto and Sakuya, I was duelling her... when I wasn't duelling her, I was training or meditating with Shitsutora and Hebimaru.

For a long training period of months, I made no progress with either Shitsotura or Hebimaru. Kurayami and I duelled constantly in the manor's courtyard where I came to see her true might and understood that she had certainly been underestimating me quite a bit in our first match. Unlike me, I could see progress with her though. 

In regards to household management... Murasaki had been in a world of his own for a while. He confessed to me that he had found a lover and was planning to move out of the house, but he didn't know how to tell Sakuya.

I was surprised... I thought all those times that he came back smelling like alcohol and perfume, it was because he was going to some expensive brothels. Turns out that lover of his was just quite feisty. I had misjudged the boy. 

I told him that I didn't care what he did with his life. But the normal way of things would be for him to bring the girl over so that she could speak to Sakuya. Even though she was not, Murasaki viewed Sakuya as his mother.

The girl had yet to come, but I'm sure he would soon move out eventually. 

The ones that were going to be moving soon were Ryōsuke and Ryōta. Those boys gave up and the second time that Kukaku came for a visit, they suggested that they wished to go and study, they would give it their all so long as they didn't have to hold a sword in their life. 

It was Sakuya who put in an opposition request. She requested Kukaku to allow Ryota and Ryosuke to remain as 'Kamishiro' instead of the surname they were to inherit after being adopted, 'Shiba'.

Her request was so outrageous that I wanted to reproach her as then 'adoption' would lose all its meaning. But contrary to my expectations, Kukaku smoked one huff out of her pipe and said it was okay. That she intended to adopt them as her nephews anyway, not as her children. 

And so, the kids' fate was decided. The last two days before their departure Mikoto and Sakuya halted their training to spend some time with them and I allowed it reluctantly, they were doing a magnificent process and to stop now would waste a bit of their momentum, but I still allowed thinking this departure may motivate them. 

Couldn't be me, I couldn't stop.

...

*CLAANG!*

My sword crashed against that massive weapon and I felt the weight of it on my toes. 

Kurayami activated her Shikai. Her Zampakuto's name was Renketsu and the Katana took the form of a gigantic sharp-less ruler. It was a weapon that relied on its crushing damage to defeat foes.

The moment I saw it, I wanted to wield it but she refused vehemently to let me touch it directly. She was so attached to it that even Shitsutora felt jealous and pushed for me to use her whenever we fought just so she could leave a few scratches on Renketsu every time.

'You haven't even seen half of it. Hurry up and strike that bitch, Ryōma!'.

"I thought you said you didn't care–"

'How dare she replace me so quickly!'

"..."

I didn't know Zampakutō could be this petty. 

*BOOMMM!!!*

I did exactly as she wanted me to and struck that gigantic black and red ruler, but it wasn't an easy fight at all. When I struck, I felt as if that sword was pressing a lot more weight into me than it should, while Kurayami was swinging it with such ease...

I watched her smile as we fought and realised how important it was the connection between a Shinigami and its Zampakutō, she was thoroughly enjoying herself. 

I grit my teeth and put Shitsutora back in its sheath, then wielded Hebimaru. 

*RUMBLE!*

I felt a rush of madness well into me and Hebimaru gained that purplish hue. Kurayami immediately used Shunpo to retreat, but I chased. 

"Go get her, Nii-chan!" Ryosuke and Ryota screamed.

"Go, Ryoma!" Mikoto and Sakuya screamed too.

"Go Aniki!" The neighbourhood kids climbing the fence spectated our fight. 

I felt power well up in my wrist, and just like me, Kurayami descended with her strike. I frowned and wondered if the surroundings were going to be alright. 

"Go get her in your harem, nii-chan!" Ryōsuke and Ryōta completed their phrase. 

A blushing Kurayami and I stumbled, missing our strikes by mere inches. Dead silence reigned in the manor as eventually, the shrieking noise of pigs took over the world as both kids were pulled into the manor with an earful by Sakuya. 

"H-uh?! Why!?" (Ryōta)

"We just want big brother Ryoma to defeat her wrestling as he does every night with you!– ouch!" (Ryōsuke)

"You two shut up now!" (Sakuya)

That evening both kids got their asses kicked out of this mansion when Kukaku came to pick them up, with Sakuya promising she'd go visit them every month. It was a pity though, I was beginning to like them. 

...

Be it as it may, those kids may have saved a lot of people. During our fights, Kurayami and I restrain a lot of our reiatsu. Although the courtyard we use to train is massive, it is not big enough to completely restrain our energy output. 

If we were to fight seriously, it would affect the neighbourhood, so Kurayami sometimes puts Kidō barriers, but even those barriers would sometimes crumble with our attacks. 

My fights with Kurayami had reached a breakthrough in which we couldn't continue without causing absolute devastation wherever we were.

We desperately needed some training grounds. 

That same night in the bathroom I was leaning back and she was sitting next to me, scrubbing herself. 

"All specialized training grounds for Shinigami are in the Seireitei, there is nowhere we can go in the Rokungai that can offer a better performance than what we already have".

It begged one question that I meant to ask her but hadn't done so yet.

"How can I go to Hueco Mundo?".

"Are you crazy?" She retorted. 

"If we go to Hueco Mundo, we won't have to worry, right? For what I know that's a massive barren land".

"Ryōma, Hueco Mundo is a dangerous and inhospitable place filled with millions of hollows, not a training ground–"

"Are you shivering?~" I teased her. Kurayami glared at me, she made one quick motion and before I knew it, she was straddling me in the bath. 

"... if you're scared of Hueco Mundo just say so~" I held her slim waists at either side.

*BANG!*

The wet sponge smashed my face and she leaned down and embraced me, pressing her whole body, boobs first, against me. 

"Do whatever you want... I'll just follow you" Kurayami exhaled a hot breath on my ears and got comfortable, I also embraced her tightly against my body... if she wanted this kinship now, I wasn't going to refuse. But I still gave a subtle stare at the bathroom door, they weren't coming yet.

"But you still haven't answered my question? How can we enter?".

"The only way to enter Hueco Mundo is through a natural Garganta. Hueco Mundo is essentially a limbo, a separate dimension from the world of the living and the Soul Society. Not only that but Hueco Mundo is a 'lost' world and as such there are no spatial coordinates that can lead to it. The only way to enter Hueco Mundo is through the canalization of the negative reiatsu of hollows. Those two are like magnets that attract one another; this negative energy in hollows naturally forms a Garganta that leads them to Hueco Mundo as such there is no way for a shinigami like me or you to naturally access Hueco Mundo".

"..." I sighed in dejection, once again a roundabout answer instead of a straight solution.

"But that doesn't mean there is no way" She seemed to sense my dejection and said.

"Save the long explanation and just go straight to it, woman".

"You're no fun, are you?" She turned around and leaned back against me, I don't know why, but rather than feeling aroused by her bombshell body, I felt she was just like a cat getting comfortable. Soon enough I heard the doors open and realised why she had done this. 

Sakuya and Mikoto came in and they both immediately glared at her. A slight grim popped up on her lips that made me roll my eyes. Women are always like this regardless of the world. 

Both girls came into the bath and sat opposite me. It may be my imagination but I heard the growling of tigers and the hissing of snakes... and... humming of cows?

"There are some shinigami throughout history that have come with ways to open gates to Hueco Mundo through the use of technology. I don't know a way, but I know someone who may know a way... my sister. The man who was her colleague, Urahara Kisuke, was a genius. If there is someone capable of doing so... it would be him. There is also Captain Kurotsuchi... but just to talk to him is so difficult, let alone request something out of him".

As I was deep in thought, Kurayami turned around with painfully slow movements, plucking her exotic ass out of the water and towards Sakuya before she sat back down on me with a grim. 

"If you attended the academy you would have access to all those facilities, but you're just stubborn" She pulled my cheeks, "You can have special training facilities, learn Kidō faster and spar with the best shinigami around. And you also have Captain Unohana to sponsor you, stop being so stubborn–".

"I'm not doing it".

*SPLASH!*

I pushed her into the water before sharp glares managed to actually kill. But it was all for nough, Kurayami recovered quickly and hopped on me, only to get her shoulder grabbed by Sakuya. 

!!!

Kurayami stopped and watched the hand holding her shoulder with a mocking grim. Two pairs of delicious breasts met in front of me. Kurayami had a clear disadvantage in front of Sakuya's mountains. I knew a fight was about to break loose at any moment and quite pitied Sakuya despite her bravado. 

Mikoto also saw the fight coming and quietly sat on my lap and requested a protective hug, taking advantage that the other two were distracted. 

"What do you think you're doing?~" Kurayami smirked.

"Get off, you're making Ryōma uncomfortable" Sakuya said, but I could hear the voice sound more like a stutter. Her ass was bigger... her boobs were jigglier... but she still couldn't defeat Kurayami in a fight even if she hit that tree with a bokken ten thousand more times. 

"Make me".
