Bankai Hollowfication?

"Tsuna, additional services come with an extra charge."

Urahara strolled over in his dark green coat, while Hiyori followed behind him, constantly waving her slipper and urging him along like a foreman.

"Move faster, baldy!" Hiyori mercilessly kicked Urahara in the ass again, sending him staggering over to Tsuna.

"Hiyori, isn't everything fine?" Urahara said helplessly, rubbing his backside. He had long sensed Kensei's violent spiritual pressure vanish, so he was in no hurry regardless of whether he made it in time.

What entered Hiyori's sight was Muguruma Kensei lying unconscious. He did not appear to be seriously hurt, but despite realizing she had worried too much, Hiyori still clicked her tongue in displeasure.

"Shopkeeper, don't you have any after-sales service?" Tsuna refused to fall for Urahara's trap and pointed at Hirako instead. "Besides, they were the ones who called you here. You should be charging them."

"Hey! You—"

Hiyori's anger flared again. Just as she was about to vent it on Tsuna, Lisa sealed Hiyori's mouth with her huge breasts. Unlike Hiyori, Lisa had truly witnessed the spiritual pressure Tsuna unleashed earlier. At that level, Tsuna could suppress their entire group by himself. Letting Hiyori run her mouth would only cause trouble.

"Kisuke, forget about that. Come check on Kensei," Hirako said to Urahara Kisuke. Urahara was the expert in this field, having helped them resolve their Hollowfication problem.

Urahara Kisuke took out a strange instrument and scanned Kensei from head to toe. He quickly reached a conclusion. "For now, Muguruma Kensei has no major problems aside from some exhaustion. Hachigen can assist him with Kaido. After resting for a while, he'll be fine."

Hearing that Kensei was all right, the other Visored went back to doing their own things. Rose hummed a tune, Aikawa Love pulled out a manga, Lisa had somehow already taken out an adult magazine and begun reading, while only Kuna Hak and Hachigen tended to the unconscious Kensei. Of course, the noisy Kuna Hak was not much help.

"So, what exactly happened?"

After learning the details from Hirako, Urahara pretended to wipe away nonexistent sweat and fanned himself with his folding fan. "That was really close. Tsuna, you were far too reckless."

"Reckless? I already held back. Mr. Tessai can testify to that. Who knew Muguruma was so weak?" Tsuna said. He had never expected to beat Muguruma Kensei into a Hollowfication state.

"Haha." Urahara laughed awkwardly. He knew how strong Tsuna was after activating Bankai. Muguruma Kensei truly was no match for him.

"By the way, have you never tried Hollowfication after activating Bankai?" Tsuna asked Hirako.

"Hollowfication after Bankai?" Hirako lay back on the ground with a bored expression. "If it were possible, Kensei wouldn't have lost his mind instantly."

"Kensei is the only one among us who has attempted it. The rest of our Bankai aren't suitable for it." Hirako recalled, "It was the same that time. The moment Kensei put on his mask after activating Bankai, he completely went berserk and began attacking indiscriminately."

"However, Kensei's Hollowfication wasn't as deep that time. I exhausted his stamina with Sakanade before ending his Hollowfication. Because of that attempt, none of us have tried Hollowfication after Bankai again."

"After all, the rest of our Bankai have too wide a range. It's easy to hurt allies," Hirako said, spreading his hands with feigned helplessness.

"Then what is the point of your Hollowfication? You can only use it in Shikai. Doesn't that make you no different from the other Vice-Captains?" Tsuna questioned.

"Hey, hey, Tsuna, it's not that we don't want to try. There's no way to do it. You saw what happened to Kensei. If the rest of us go berserk, it'll be even more dangerous," Hirako said.

"No wonder Aizen saw you as failures. You don't even dare attempt Bankai Hollowfication. What makes you think you can point your blades at Aizen? Your Hollowfication in Shikai?" Tsuna sneered.

"Aizen! How do you know that name?!"

Tsuna's words once again provoked the Visored's fury. Every member of the Visored glared at him. The name Aizen was taboo to them, yet Tsuna had dragged it into the open.

"What does a baldy like you know? Sooner or later, I'll chop Aizen down!"

Hiyori charged at Tsuna with an Asauchi in one hand and a slipper in the other. It seemed that before defeating Aizen, she intended to teach Tsuna a lesson first. But after taking only two steps, a terrifying spiritual pressure descended upon her. Hiyori had no choice but to drive her Asauchi into the ground to keep herself upright. She could not even take another step.

"You can't even withstand this much spiritual pressure, and you want to cut down Aizen? Don't make me laugh!"

Hiyori struggled to raise her head. What met her eyes was Tsuna's icy gaze. Tsuna had long grown tired of her violent temper. People with no strength who still shouted wildly would only end up dragging their comrades down.

"All right, Sawada Tsunayoshi, don't lower yourself to Hiyori's level."

Hirako stepped between them, blocking Tsuna's cold gaze and spiritual pressure. Only then did Hiyori get a chance to catch her breath.

"In Aizen's eyes, a Bleach's battle is a battle of spiritual pressure. If you don't even have Captain-level spiritual pressure, I advise you not to join the fight. Otherwise, your comrades will have to distract themselves taking care of you." Tsuna stood up with a serious expression. If the Visored dared draw their blades on him again, he would let those fools feel the terror of power.

Contrary to Tsuna's expectations, Hirako did not get angry. Instead, his eyes lit up. "You're going after Aizen too? The enemy of my enemy is my friend. We can become comrades."

Hirako had seen Tsuna's strength. It would naturally be best if Tsuna was willing to fight Aizen alongside them.

"Comrades? You?" Tsuna laughed. "One only plays music, one only reads manga, one loves adult magazines, one fantasizes about being a superhero, one is uselessly raging without any strength, and then there's you, someone who hasn't even mastered his own Shikai. Being your comrade? That would be difficult."

"Among you Visored, only that fat uncle and the guy lying on the ground still remember to train. Everyone else has their own hobbies. Do you really want revenge?"

Tsuna's words pierced everyone's hearts like sharp swords. Was it fear of Aizen, or had their interests eroded their resolve? Most of the Visored had to admit that they had grown complacent.

"Can I hear your thoughts? About my Shikai," Hirako asked.

"Do you even need to ask? Sakanade, the Zanpakuto that reverses everything! And what about you? You've only developed visual inversion. Temperature, the five senses, spiritual pressure, even cognition—there are countless things you could reverse, yet you developed only the most powerless aspect: vision." Tsuna was so angry he laughed. "I don't know how Sakanade acknowledged you. Is this level enough for you to learn Bankai?"

Hirako suddenly sensed a disturbance. It was his Zanpakuto. Sakanade agreed with Sawada Tsunayoshi's words?

"I really have grown complacent." Hirako held his Zanpakuto level as everyone watched in surprise.

Influenced by Hirako, the Visored all looked toward their own Zanpakuto. Nearly a century had passed, and aside from Hollowfication, their combat strength had not improved at all. Could they truly take revenge on Aizen? How terrifying had that man's strength become by now?

Seeing the Visored lost in thought, Tsuna walked over. "I noticed something during my battle with Muguruma Kensei."

"Please, go on." Urahara sat up straight. Whenever Tsuna shared information, Urahara was at his most serious.

"I felt Hollow's power within Muguruma Kensei's Zanpakuto. In other words, that Zanpakuto possesses both Bleach and Hollow power."

"I suspect that with sufficient training, Muguruma Kensei may be able to master the powers of both Bankai and Resurrección at once."

"Resurrección?" This new term piqued Urahara's interest.

"Just like Sora Inoue. After you separated part of his power from him, it took human form. Conversely, if his original power is returned to him, he will revert to his strongest form. I call that kind of attempt Resurrección."

"And Muguruma Kensei's Zanpakuto clearly contains the violent Hollowfication power he just displayed. If he can successfully master Resurrección, wouldn't Muguruma Kensei be able to unleash that mad power from before whenever he wants?"

"Interesting. What about Hirako and the others?" Urahara asked.

"They don't have it. I suspect that this state can only arise when someone is infinitely close to Hollowfication under Bankai, then forcibly knocked unconscious to deactivate Bankai."

"As everyone knows, Shikai is a reflection of a Bleach's soul power, while Bankai is the manifestation of that power. To some extent, it is also the release of a Bleach's true power. Being forcibly rendered unconscious in that state causes the already-released Zanpakuto to be forcibly sealed back into its Asauchi form. I think that's where the Hollow's power on that Asauchi came from."

"Interesting. I'll take this Asauchi back first." Urahara picked up Kensei's Zanpakuto and spoke to Hirako, who naturally had no objection.

Urahara turned back to Tsuna. "I've also been researching the Visored's Hollowfication lately. I found that because they have no Hollow's power within their bodies, they undergo Hollowfication while in their Bleach state every time. That is why they are so prone to going berserk."

"If we seal a Gillian inside each of them as a source of power, perhaps their Hollowfication could become even stronger. It may even be possible for them to achieve the Resurrección you mentioned."

"That is indeed interesting." Tsuna agreed. "But wouldn't sealing it directly inside their bodies be too dangerous? What about sealing it into their Zanpakuto? Isn't that your specialty, Shopkeeper?"

Kurotsuchi Mayuri was not the only one skilled at modifying Zanpakuto. Urahara's endlessly varied Shikai and his Bankai, which was modification in all but name, showed that Urahara Kisuke was also skilled at modifying Zanpakuto.

"Hey, hey, hey, aren't you two discussing something pretty terrifying?" Hirako could not help interrupting. Why did these two look as though they were treating them like experimental materials?

"Isn't it because you're too weak? I can't even properly practice Resurrección..." Tsuna complained, glancing at Hirako.

"No matter what, I used to be the Captain of the 5th Division. I'm not that weak, am I?"

"That's right." Hirako voiced his opinion, while Rose beside him chimed in. He had once been the Captain of the 3rd Division.

"You? One Bankai is for clearing fodder, and the other has ears as its weakness. Are you really strong?" When it came to the strength of Bankai, Hirako and Rose had no right to brag. "On the other hand, Uncle Love, I'm very interested in your hammer's Bankai."

"My Bankai is too dangerous to use casually. It could injure my comrades," Aikawa Love patiently explained to Tsuna.
