Cultivating Beyond Bankai?
One by one, the trainees dispersed. Tsuna leaned down and asked Koume, "Koume, how are you feeling? Do you want to rest?"
Muramasa's ability to materialize his Zanpakuto also consumes Koume's spiritual pressure. The reason Muramasa was able to control a large number of Zanpakuto to rebel in the story was because he was overdrawing his own power.
After each battle where he forcibly materialized his Zanpakuto, Muramasa had to devour a large number of Hollows to replenish his lost power. This led to Muramasa going berserk and transforming into a different kind of Hollow.
To Tsuna's question, Koume gently shook her head and said, "I'm not tired, I can keep going."
"No! Sawada-sensei, please let Koume rest for a while." It was Muramasa who spoke up for Koume. Didn't he know whether Koume was tired or not during the process of her Zanpakuto materializing?
"That's great, we've found someone we can entrust with this." Tsuna said to Koume Muramasa, "Let's rest for today, and tomorrow we'll go to the First Division to see Old Man Yamamoto."
Tsuna continued, "If Koume doesn't want to rest so early, Muramasa can show you around Seireitei so you can get familiar with the surroundings."
"No problem, leave it to me."
As the Zanpakuto of the former Kuchiki noble family, Muramasa is quite familiar with the environment of Seireitei. Although it has been hundreds of years since he has had a proper visit, the Soul Society had not changed for thousands of years before Tsuna appeared.
The next day, they arrived at the First Division Barracks, supposedly to visit Genryūsai Shigekuni Yamamoto, but Genryūsai Shigekuni Yamamoto wasn't there at all. Led by Genjirō Ōko Oki, Tsuna and Koume arrived at a very secluded location.
Even before entering the area, they could hear bursts of thunder. Genjirō Ōko had no intention of going in and returned to the First Division after bringing Tsuna and the other two there.
Tsuna had nothing to fear, Koume was even less perceptive of her surroundings. The two of them walked into this land of thunder together.
This was in a valley. As soon as Tsuna entered, he saw dark, heavy clouds and flashing lightning.
In Soul Society, besides Yoruichi, only Sasakibe currently possesses Lightning Attribute power.
Tsuna hadn't interfered with the Sasakibe's training, not to mention that this guy had ambushed him, which had already annoyed Tsuna.
Since the Sasakibe himself was personally instructed by Genryūsai Shigekuni Yamamoto, Tsuna simply didn't bother to go looking for the Sasakibe.
As for how well Genryūsai Shigekuni Yamamoto can train the Sasakibe, Tsuna only hopes that he won't be cannon fodder. At least a weaker Bleach would still have some use, but the Sasakibe was killed by an arrow at the very beginning of the bloody battle.
Thunder roared and howled as bolts of lightning relentlessly attacked the central flames in the valley, but these attacks seemed to have little effect.
The appearance of Tsuna and his friends naturally attracted the attention of Sasakibe and Genryūsai Shigekuni Yamamoto. The two of them stopped their attacks and walked towards Tsuna.
"Oh, practicing? Sorry to bother you," Tsuna said casually, without any hint of embarrassment at disturbing others.
Before Genryūsai Shigekuni Yamamoto could speak, Sasakibe said first, "Sawada Tsunayoshi, let's find a chance to have another match."
Tsuna glanced at Sasakibe and said, "Pretty confident, huh?"
"I dare not fail to live up to the Captain-Commander's teachings!"
Sasakibe was indeed very confident. He had long since regained his Bankai, and after witnessing Hyōrinmaru's ability to control celestial phenomena, he realized that his Zanpakuto could also control celestial phenomena.
He attempted to study the celestial phenomena control direction of Ōetsu Nimaiya, and finally completed this move when he placed the magnificent canopy on the sky, transforming himself into lightning to launch the attack.
In Sasakibe's view, Genryūsai Shigekuni Yamamoto was only forced to defend against his new move, and this attack method should be able to hold its own against Tsuna.
A draw would be ideal; it would give Tsuna a bit of satisfaction, and Sasakibe wouldn't lose face as Bleach, making both sides happy.
Tsuna didn't speak, but instead gave Koume a look. Koume immediately used Muramasa to control the Sasakibe that Genryūmaru was using.
A samurai-like man carrying a small house on his back and a long staff wrapped in a white cloth appeared before the Sasakibe.
It was Genryūmaru. Koume immediately materialized Genryūmaru, and as Genryūmaru left the Zanpakuto, the dark clouds overhead dissipated.
"Before you fight me, you should fight your Zanpakuto first. Compared to Old Man Yamamoto, he is your best teacher."
Sasakibe frowned as he looked at Tsuna. He didn't quite agree with Tsuna's statement. In his opinion, there was no teacher better than Genryūsai Shigekuni Yamamoto.
In order to improve his strength as much as possible, Sasakibe had been training hard here. He was unaware of many things that Seireitei, and Genryūsai Shigekuni Yamamoto had no intention of explaining them to him.
"Sasakibe, let's retrieve the power of Genryūmaru first." Genryūsai Shigekuni Yamamoto pointed at Sasakibe's Zanpakuto, left these words, and then walked with Tsuna towards the depths of the valley. "I'll go with Tsuna first."
Sasakibe stared blankly at his Zanpakuto. After its release, his sword should have resembled a Western sword, but now it had reverted to its Asauchi form. Sasakibe immediately realized that it was Genryūmaru's doing.
"You stole the power of Genryūmaru, didn't you? I can get Genryūmaru back if I defeat you, right!"
Sasakibe didn't notice was that his tone was somewhat harsh, Genryūmaru's already sorrowful face look even worse.
Sasakibe's voice wasn't deliberately concealed, or rather, it was meant for Tsuna to hear; Tsuna simply shook his head silently.
Muramasa didn't intentionally try to sow discord between his master and his Zanpakuto, but since Sasakibe came out with such a blunt tone, it's obvious that he had already offended Genryūmaru.
Tsuna had no interest in reminding Sasakibe; Sasakibe was left to experience the path he had chosen.
Genryūsai Shigekuni Yamamoto stopped only after walking deep into the valley. He looked at Koume Muramasa, but asked Tsuna, "Sawada Tsunayoshi, is it what I thought?"
Back when Tsuna mentioned that Muramasa could greatly increase the speed at which Bleach train in Blade Zen, Genryūsai Shigekuni Yamamoto realized that the true use of Muramasa was not to teach the Vice-Captain Bankai, but to increase the captains' recognition of their Zanpakuto.
This was the power that Sawada Tsunayoshi had prepared in advance so that the captains could train to Beyond Bankai. That's why Genryūsai Shigekuni Yamamoto personally guarded the real world for several days, just to see Muramasa become a force of Soul Society.
The fact that Tsuna didn't actively seek out the other captains but instead found him first indicates that Tsuna also wants Genryūsai Shigekuni Yamamoto to master Beyond Bankai as quickly as possible.
"That's right." Tsuna didn't deny it, "But I'll still remind you, if possible, I suggest you put away your intimidation tactics, Old Man Yamamoto. Pure submission by force won't make your Zanpakuto truly acknowledge you."
"What you really need to do is understand the dissatisfaction your Zanpakuto has with you, and through the reflection of your Zanpakuto, understand your true self."
Having said all he needed to say, Tsuna didn't add anything more. He believed that an old fox like Genryūsai Shigekuni Yamamoto would understand his meaning. Tsuna nodded to Koume, Koume understood and activated the power of Muramasa.
Muramasa appeared beside Genryūsai Shigekuni Yamamoto, his mouth moving incessantly as he activated his whispering ability.
However, this time things didn't go as smoothly as he had imagined. Muramasa had almost worn out his lips trying to Ryūjin Jakka he was ignored. Muramasa walked back to Koume's side with a somewhat unpleasant expression.
"What's going on?"
"Ryūjin Jakka is unwilling to materialize; I feel like he's been beaten into submission." Muramasa glanced at Genryūsai Shigekuni Yamamoto almost imperceptibly.
Tsuna was speechless upon hearing this news. Genryūsai Shigekuni Yamamoto to compress the Great Fire Sword into the Zanka no Tachi, so he must have beaten Ryūjin Jakka quite a few times during his Blade Zen training.
It's no wonder that Ryūjin Jakka was unwilling to come out; in his view, coming out meant leaving again, so he might as well stay quietly in his inner world.
"Is there no other way?" Genryūsai Shigekuni Yamamoto was also somewhat speechless. This was obviously something he didn't want to see, but Ryūjin Jakka was unwilling to come out, there weren't many options he could offer.
"Let's use our old skills, Muramasa, and take control of him," Tsuna said, then reminded Genryūsai Shigekuni Yamamoto, "Grandpa, relax and don't resist."
Muramasa glanced at Genryūsai Shigekuni Yamamoto, who had nodded in agreement, and reluctantly said to Koume, "Koume, use Bankai."
Muramasa also had a very high opinion of Koume, so he directly passed on the power of Bankai to Koume.
Koume Yu nodded, "Bankai! Gokujō Tsumakiyori Muramasa!"
Muramasa's body emitted a purple light, and then his figure gradually became ethereal as he lunged towards Genryūsai Shigekuni Yamamoto.
The power of Bankai allows Muramasa to enter the target's inner world, but to be honest, he's not particularly willing to enter Genryūsai Shigekuni Yamamoto's mind, and he's also afraid of being punched away by Genryūsai Shigekuni Yamamoto.
Fortunately, Tsuna had anticipated this, allowing Genryūsai Shigekuni Yamamoto to completely relax, Muramasa easily found Ryūjin Jakka's place in Genryūsai Shigekuni Yamamoto's inner world.
Without a single word, Muramasa directly used his ability to control Ryūjin Jakka's mind, and he dragged Ryūjin Jakka back to Soul Society at lightning speed.
This is Tsuna's intention: Ryūjin Jakka is unwilling to come out, then forcibly drag him out. As for how to handle the aftermath, that's something Genryūsai Shigekuni Yamamoto should consider.
Two breaths later, with a whoosh, Genryūsai Shigekuni Yamamoto's cane erupted with intense flames, forming a fire tornado in the air. Enveloped in the fire tornado, a face contorted with rage appeared before everyone.
Ryūjin Jakka wore a crimson haori, had a small mustache, and wore a samurai braid on his head. Flames constantly surged in his eyes.
Tsuna was shocked. How come this Ryūjin Jakka looked so much like a young Genryūsai Shigekuni Yamamoto?
He was irritable, full of anger, and had an arrogant, domineering expression, as if he could burn everything to ashes at the slightest provocation.
"Yamamoto Shigekuni, are you ever going to shut up?!" Ryūjin Jakka appeared. "You think you can turn the sky upside down? What kind of skill is it to beat me up here?!"
Wow, we've stumbled upon some juicy gossip! It turns out that Genryūsai Shigekuni Yamamoto himself harbored resentment towards the rule of the Soul King Palace, though he had never voiced it before. Now, through the mouth of Ryūjin Jakka, who has been manipulated by Muramasa, he has revealed everything.
A powerful spiritual pressure impacted Tsuna and Koume. Genryūsai Shigekuni Yamamoto calmly took off his shirt, revealing his muscular upper body.
"Sawada Tsunayoshi, you can leave now. I'm going to teach this reckless Zanpakuto a lesson!"
Tsuna picked up Koume and used Genryūsai Shigekuni Yamamoto's spiritual pressure to propel them away quickly. He had to get out of there quickly after eating the melon, so as not to get blood splattered on himself.
