[Chapter XIII - Startling Revelation]

BOOM!

A colossal explosion shook the very foundations of Hueco Mundo, obliterating any unfortunate hollow within its deadly radius. At a safe distance, all of Ichigo's bodies landed, their chests heaving as they panted heavily. Their collective gaze fixated on the source of the devastation, the malicious smile adorning Sosuke's face as he held Ulquiorra's devastating Lanza del Relampago at his side.

"You never seem to know when to give up, Ichigo Kurosaki," Sosuke taunted, his grin unwavering. "You and the rest of your bodies struggle just to stand in my presence, yet you truly believe you can defeat me?"

Ichigo remained silent, letting Ulquiorra-Ichigo voice their collective determination.

"If you truly think that, then you are a fool, Aizen-sama," Ulquiorra-Ichigo stated with the emotionless demeanor of the Espada. "The boy will continue to fight, not because he wants to win, but because he must win."

Sosuke's grin persisted, seemingly undeterred.

"Is that so?" he responded, his eyes locking onto the Lanza del Relampago as he readied it for another attack. "Well then, I'll just have to kill one of you and reduce the rest to dust."

With a swift motion, Sosuke hurled the terrifying projectile toward Ichigo's amassed bodies. Quick as lightning, Ichigo had Jushiro-Ichigo employ Jushiro's bankai to deflect it back at Sosuke. However, Sosuke caught the enhanced projectile effortlessly, his expression one of sheer boredom.

"You cannot scratch me. I am immortal!" he cackled, releasing a potent Cero aimed directly at Ichigo's bodies.

Thinking swiftly, Ichigo ordered his bodies to scatter, each one evading the devastating blast.

Ichigo's thoughts raced as he faced Sosuke's overwhelming power.

'Shit, that power is no joke!' he cursed inwardly.

'We must defeat him quickly, Ichigo. I fear our time is running out,' Zangetsu cautioned in his mind.

Ichigo clenched his teeth, his anger boiling as he fixated on Sosuke. He swiftly readied Tensa Zangetsu, Ulquiorra-Ichigo, and Toshiro-Ichigo appearing behind him. Across from Sosuke, Renji-Ichigo, Uryu-Ichigo, and Stark-Ichigo prepared for their assault. Momo-Ichigo suddenly materialized above Sosuke.

"Bakudo #61, Rikujokoro!" she cried out.

Six tiles of pure reiatsu slammed into Sosuke with tremendous force, rooting him in place. Despite the impact, Sosuke remained unfazed, but Momo-Ichigo pressed on.

"Bakudo #63, Sajo Sabaku!"

A chain of pure reiatsu coiled around Sosuke, tightening and rendering his arms useless.

"Bakudo #79, Kubo Shibari!"

Eight black holes materialized around Sosuke, while a ninth formed on his chest. Momo-Ichigo turned to the others.

"Now!" she commanded.

"Getsuga Tensho!" "Gran Rey Cero." "Guncho Tsurara!" "Hikotsu Taiho!" "Licht Regen!" "Cero Metralleta," cried out several of Ichigo's bodies.

A deafening explosion erupted as the combatants landed back with the other bodies, surveying the aftermath.

Sosuke emerged from the smoke seemingly unscathed, his arrogant grin still etched upon his face. He regarded them with a mocking air of disappointment.

"Is that all? How disappointing..." he taunted, his voice oozing with disdain.

Ichigo's eyes widened as the dust was instantly blown away, revealing Sosuke completely unharmed, Tensa Zangetsu in one hand and Zanka no Tachi in the other.

"Well then, let me show you what true power is," declared Sosuke.

Sosuke vanished, reappearing behind Gin-Ichigo, who turned just in time to block Tensa Zangetsu's blow before being sent flying into Matsumoto-Ichigo, tumbling yards away.

Kenpachi-Ichigo and Grimmjow-Ichigo leaped in with their zanpakuto held high, but Sosuke effortlessly used Zanka no Tachi to slice their zanpakuto in half before kicking them away. Momo-Ichigo and Kisuke-Ichigo extended their hands towards Sosuke.

"Hado #88 Hiryu Gekizoku Shinten Raiho!" they both shouted.

Two blue beams of reiatsu surged towards Sosuke, only to be met with an orange triangular shield that blocked their path. In an instant, Sosuke appeared behind the two, ready to strike them down.

Yoruichi-Ichigo intervened just in time, though she sustained a nasty gash on her side. Marechiyo-Ichigo, Sajin-Ichigo, and Yammy-Ichigo charged at Sosuke from behind with full force.

"Getsuga Tensho," Sosuke muttered while swinging Tensa Zangetsu.

The familiar black arch slammed into the three, sending them tumbling away from the sheer force. Suddenly, a row of enormous blades emerged from the ground, dispersing into deadly bladed sakura petals. The deadly barrage hurtled towards the remaining Ichigo bodies.

Byakuya-Ichigo immediately engaged them with Byakuya's bankai, while Orihime provided assistance with Shun Shun Rikka, and Renji-Ichigo utilized the hardened body of Hihio Zabimaru.

Seizing the distraction, Ichigo swiftly shunpo'd behind Sosuke's back, with Soifon-Ichigo and Ulquiorra-Ichigo closely following. Soifon-Ichigo held Jakuho Raikoben aimed at Sosuke, while Ulquiorra-Ichigo wielded a Lanza del Relampago. Sosuke chuckled at their attempt.

"Do you really think I can't evade those?" he sneered.

"Shatter!"

Sosuke looked upward just in time to see Sosuke-Ichigo completing the release of his former zanpakuto.

"Kyoka Suigetsu!" declared Sosuke-Ichigo.

Initially, it appeared as though nothing had changed. However, Sosuke, well-acquainted with his own zanpakuto, couldn't help but grin.

"You truly believe you can defeat me using my own zanpakuto?" Sosuke taunted.

"I'm not finished!" Shinji-Ichigo bellowed, "Collapse, Sakanade!"

The moment Shinji-Ichigo uttered those words, Sosuke's entire world flipped upside down.

"Now, try to evade them when your actions are inverted, and your own illusions deceive your senses," Ichigo challenged.

Both Soifon-Ichigo and Ulquiorra-Ichigo unleashed their devastating projectiles at Sosuke. A smirk crept across Sosuke's face. Suddenly, the two projectiles detonated just before impact, causing a massive explosion that forced all of Ichigo's bodies to shield their eyes. When the dust settled, Sosuke remained unharmed, standing defiantly.

"Should you truly be that surprised?" Sosuke inquired, his grin unwavering.

Then, the unthinkable occurred. Sosuke-Ichigo's and Shinji-Ichigo's zanpakuto shattered in their hands, causing their eyes to widen.

"It's futile to continue when you know you're about to be utterly pulverized," Sosuke asserted. He stretched his arms wide, gazing toward the sky. "Simply concede defeat, Ichigo Kurosaki."

Ichigo clenched his teeth as he contemplated his options.

'Nothing seems to get through! No matter what kind of attack I throw at him, he blocks it!' Ichigo thought, frustration gnawing at him. He surveyed his battered bodies, all in dreadful shape, including his own.

'And my bodies can't hold out for much longer…' Ichigo mused inwardly.

Ichigo turned his attention back to Sosuke, a hint of determination in his eyes.

'You're considering it, aren't you?' Zangetsu mentally conveyed to Ichigo.

Ichigo let out a weary sigh and closed his eyes, the weight of his decision bearing down on him.

'It's the only way to ensure that Aizen doesn't terrorize Soul Society and the World of the Living,' Ichigo responded mentally to Zangetsu's concerns.

'Ichigo... if you do this, there's a very great chance you—' Zangetsu began, trying to convey the gravity of the situation.

'I know, Zangetsu. I know,' Ichigo interrupted, determination burning in his thoughts. 'But I'm willing to do whatever it takes to take Aizen out for good and put an end to his misery.'

Zangetsu fell silent, contemplating the resolve in Ichigo's words.

'Are you sure about this, Ichigo?' Zangetsu eventually asked, seeking one last confirmation.

Ichigo opened his eyes and exchanged a brief glance with Yoruichi-Ichigo. Then, he returned his gaze to Sosuke, his determination unwavering.

'I'm sure,' Ichigo replied firmly, his resolve reflected in his eyes.

Sosuke grinned at Ichigo as his bodies regrouped around him.

"Oh? So you're still going to try and stop me?"

Ichigo's expression hardened as all of his bodies began to link arms, forming a circle around Sosuke.

"I still have one more trick up my sleeve, Aizen," Ichigo declared. His eyes locked onto Sosuke's, radiating a sense of unwavering determination.

"With this technique, I will truly end you... in a single instant."

"Eh?!" cried Rukia, her eyes widening as she stared at Kisuke. "There's such an ability?"

Kisuke simply shrugged, maintaining his enigmatic demeanor. "I'm not certain, but according to Kurosaki-kun's journal, there is indeed such an ability. He discovered it through the combined intellect and wisdom of all his bodies' memories."

Uryu, always the analytical thinker, placed a hand on his chin, deep in thought. "If such an ability were to exist, the user would possess the power of a god... in every single one of his bodies."

Momo's expression grew somber. "But at a terrible cost..."

Orihime's eyes widened with fear as she pieced together the implications. "So, if Kurosaki ever uses this ability, then he'll..."

Yoruichi, a wise and experienced figure, completed Orihime's thought with a solemn tone. "... then he will completely lose who he is, memory and soul, lost within the memories of others, while all the bodies live on without any power."

A heavy silence hung in the air as the group absorbed the gravity of this revelation.

"Let's just hope that dumbass doesn't decide that he needs to use it," Renji grumbled, his frustration and concern evident.

"He's facing Sosuke Aizen along with a group of powerful doppelgangers, so the odds are pretty high," Uryu interjected, his voice tinged with worry.

Kisuke lowered his gaze to the journal in his hand for a moment, deep in thought. Then, he looked up at the group with a serious expression.

"He even had a name for this ability," Kisuke revealed.

Curiosity and concern filled the eyes of those gathered.

"A name?" Rukia inquired.

Kisuke nodded, his voice carrying a hint of weight. "This ability, which grants Kurosaki-kun incredible power at the cost of his very soul... it's called..."

"Final Exodus," declared all of Ichigo's bodies simultaneously, their voices resolute and their eyes filled with determination.

Sosuke's eyes widened in sheer disbelief as he felt an overwhelming surge of reiatsu from each and every one of Ichigo's bodies, each power level rivaling his own.

"I-Impossible!" he stammered, shaken by the sheer magnitude of energy before him.

Ichigo and all his bodies gazed down upon Sosuke, their eyes locked onto their adversary with unwavering resolve.

"Let's bring this to an end, Sosuke Aizen," they declared in perfect unison, their voices ringing with conviction.
