[The scene shifted to show other members of the Gotei 13 positioned across various battlefields throughout Seireitei.]
[Upon sensing their strongest leader's overwhelming spiritual pressure, captains like Kyoraku Shunsui, Soi Fon, and Ukitake Jushiro felt their spirits lift with renewed hope.]
[Captain Kyoraku adjusted his hat, a relieved smile crossing his features.]
[Kyoraku: "Well now, looks like the old man's finally taking this seriously. This battle should be over soon."]
[However, the Quincy opposing him merely smiled with cold confidence.]
[Robert Accutrone: "You may have made a grave miscalculation, Shinigami."]
[He raised his rifle with practiced ease.]
[Robert: "Your leader will fall to our leader. And you're mistaken if you think only you will be inspired by your captain's arrival. We Quincy will be equally motivated to completely annihilate every last Shinigami."]
[Meanwhile, back at the main battlefield, three Sternritter suddenly burst from concealment, launching a coordinated assault on Captain-Commander Yamamoto.]
[The attackers moved with supernatural speed, convinced their combined might could overwhelm even the legendary Shinigami.]
[But Yamamoto merely smiled with cold disdain.]
BOOM!
[In the next instant, a massive pillar of fire erupted skyward, visible throughout all of Seireitei. The flames reached so high they seemed to pierce the very heavens.]
ROAAAR!
[The conflagration was like a volcanic eruption, a column of pure destructive force that could be clearly witnessed by every Shinigami and Quincy across the battlefield.]
[Without question, under such an overwhelming attack, the three Sternritter were either dead or critically wounded.]
[Captain Kyoraku chuckled as he observed the distant inferno.]
[Kyoraku: "Seems you were wrong about something important. Our old man Yamamoto isn't a Shinigami who can be measured by common sense. He's a terrifying existence beyond normal comprehension. Making an enemy of him is your greatest mistake."]
[The three Sternritter who had dared challenge Yamamoto were now little more than charred remnants, having been reduced almost to ash on the spot.]
If you look too closely, you'll be blinded. Get too near, and you'll melt instantly.
[They had truly overestimated themselves, thinking they could ambush Captain-Commander Yamamoto. Such hubris was laughably naive.]
[The false Yhwach observed the aftermath with cold indifference.]
[Royd Lloyd (as Yhwach): "What a bunch of fools. Intruding upon the battle of the strong without permission leads to such an end, doesn't it?"]
[His callous disregard for his subordinates' lives was exactly what Yamamoto expected from the real Yhwach.]
Such complete disregard for his followers' lives... this is indeed the Yhwach I remember.
[Yamamoto's grip tightened on his zanpakuto.]
My current self must end you completely. I will draw the final punctuation mark on that war from a thousand years ago!
[Without further words, Yamamoto burst forward with devastating speed, bringing his blade down in a tremendous overhead strike.]
SHING!
[The false Yhwach appeared genuinely surprised, quickly retreating dozens of steps to avoid the attack.]
[Royd Lloyd: "You're old, Yamamoto!"]
[He attempted psychological warfare.]
[Royd Lloyd: "But seeing you so enraged reminds me of your younger self! You were just as angry back then!"]
[Yamamoto continued his relentless assault, forcing his opponent to finally draw his own blade in defense.]
CLANG! CLASH! RING!
[Yamamoto snorted with satisfaction.]
[Yamamoto: "Finally drew your sword!"]
[The false Yhwach parried desperately.]
[Royd Lloyd: "Why? Have you been waiting for me to release my zanpakuto?"]
[Yamamoto's eyes blazed with righteous fury.]
[Yamamoto: "What do you think I've been waiting for?"]
[His spiritual pressure began climbing to apocalyptic levels.]
[Yamamoto: "I've been waiting for the opportunity... to crush your flesh, your sword, and even your very soul!"]
WHOOOM!
[The moment those words left his lips, Captain-Commander Yamamoto's already terrifying aura intensified exponentially.]
[The scorching temperature that had already made the battlefield unbearable suddenly skyrocketed, as if the sun itself had descended to earth.]
[Then, in a phenomenon that shocked everyone present, the flames that had been shrouding their battlefield vanished instantly.]
[The false Yhwach's eyes widened with genuine surprise.]
What's happening? The flames disappeared in an instant? This is something I've never witnessed before!
[At that moment, Captain-Commander Yamamoto finally revealed his ultimate technique.]
[Yamamoto: "BANKAI!"]
[His voice thundered across the battlefield.]
[Yamamoto: "ZANKA NO TACHI!"]
FLASH!
[The previously flame-engulfed battlefield was suddenly bathed in blinding white light, as if the very concept of fire had been refined into its purest, most devastating form.]
[The entire aesthetic of the scene transformed—what had been a hellscape of orange and red flames became an almost heavenly expanse of brilliant white radiance.]
[Even Jugram Haschwalth, observing from a distance, was stunned beyond words.]
[Haschwalth: "A Bankai?! That small, charred blade—like a piece of burned charcoal remaining after flames die out—that's his so-called Bankai?"]
[His analytical mind struggled to comprehend what he was witnessing.]
[Haschwalth: "Incredible! I've never seen such a compact Bankai before!"]
[The false Yhwach, still maintaining his act, spoke with forced knowledge.]
[Royd Lloyd: "Don't underestimate him! This 'Zanka no Tachi' is a Bankai that seals all his flames within the blade itself."]
[He gestured toward the deceptively simple sword.]
[Royd Lloyd: "The first technique is 'Zanka no Tachi, Higashi: Kyokujitsujin.' A sword of fire that completely incinerates anything it cuts with explosive flames."]
[But Captain-Commander Yamamoto's expression showed mild disapproval.]
[Yamamoto: "Is that really what you think my current Bankai is? You did witness this technique a thousand years ago, didn't you?"]
[A dangerous smile crossed his weathered features.]
[Yamamoto: "But is it truly the same now? Then use your body to experience it properly!"]
[He intended to demonstrate to this Yhwach the evolution of his Bankai's new capabilities.]
[The moment Captain-Commander Yamamoto activated his Bankai, the effects rippled throughout all of Soul Society.]
[Members of the Gotei 13 across various battlefields suddenly felt extreme discomfort.]
Captain-Commander Yamamoto's Bankai... its power could literally destroy all of Soul Society if used at full strength.
[The technique was so overwhelmingly powerful that even allied Shinigami could barely endure its presence.]
[Throughout Seireitei, Shinigami found themselves struggling against the oppressive heat. Their throats became parched, their lips cracked, and breathing became laborious.]
[Captain Unohana, who was intimately familiar with the destructive potential of this technique, gazed toward the distant battle with deep concern.]
[Unohana: "Captain-Commander... please end this quickly. If you maintain this power for too long, Soul Society itself may not survive."]
[Even enemies were affected. The Sternritter who had stolen Hitsugaya's Bankai suddenly noticed the ice behind him rapidly melting away.]
The very moisture in Soul Society's atmosphere is evaporating... all because of Captain-Commander Yamamoto's Zanka no Tachi.
The chat group erupted with excitement and awe:
[Hitsugaya Toshiro: Finally! The Captain-Commander is using his Bankai again! This is the legendary Zanka no Tachi—I've always wanted to witness it, and now I can finally see its true power!]
[Shiba Isshin: Indeed! This is a technique powerful enough to alter the environment of the entire Soul Society! During their battle, other Shinigami and Quincy won't even be able to continue fighting.]
[Yhwach: Oh? It does appear quite different from the Bankai I witnessed previously. It seems that over the past thousand years, you too have undergone significant evolution! Very well, let me see how far your Bankai has developed, and whether it can truly move me now.]
[Aizen Sosuke: As expected of Captain-Commander Yamamoto—truly deserving of my admiration. Such a Bankai is indeed not easily resisted. That's precisely why I, being well acquainted with your strength, chose to seal your zanpakuto in our future encounter rather than face your full power directly.]
[Zaraki Kenpachi: Now THIS is what I call a real fight! That spiritual pressure is making my whole body shake with excitement!]
[Byakuya Kuchiki: The temperature is so intense it's affecting battles across all of Seireitei. This is the true power of the Captain-Commander.]
[Ukitake Jushiro: Please, Captain-Commander... end this swiftly. Soul Society cannot withstand this power for long.]
[Kyoraku Shunsui: The old man's finally getting serious. I almost feel sorry for whoever's facing him... almost.]
Even Aizen found himself curious about how Yhwach would respond to Captain-Commander Yamamoto in this unprecedented state of power.
