Boom!
Aizen crashed heavily into the ground, leaving a deep crater, while a gash appeared on Zaraki's chest, spewing a large amount of blood.
Zaraki was severely wounded, and the tangible Reiatsu above Aizen's head showed faint cracks.
"Are you afraid, Ichigo?" Aizen stood up and came before Ichigo.
"Ah!"
Ichigo roared and charged at Aizen.
"Full of openings."
Facing Ichigo's forceful attack, Aizen casually swung his sword.
Crack!
Ichigo's Hollow mask shattered instantly, and his body plummeted from the sky.
"Kurosaki!"
Uryū and the others wanted to step forward, but were stopped by Unohana.
Even the captains were in such a state, their intervention would only lead to more casualties.
At this moment, a figure flashed and caught Ichigo.
"Dad?"
Ichigo looked at Isshin, dressed in a shihakushō and with a serious expression, falling into deep confusion. The dullness in his eyes was replaced by color.
"I'll explain my situation to you later."
With that, Isshin gave Ichigo a headbutt.
"Kid, don't give up so easily."
"Ow!"
Ichigo clutched his forehead.
Although he was very curious about Isshin's situation, he wouldn't press for answers, trusting his father had his reasons.
Isshin then stood before Aizen, facing him.
Aizen looked at Isshin playfully.
Suddenly, a red arrow of light shot towards Aizen from behind. Aizen sidestepped, looking at the figure behind him.
"So you've finally arrived, Kisuke?"
"Long time no see, Aizen."
Kisuke stood on a broken wall, pressing down on his hat brim, his expression unreadable.
Kisuke said, "After a hundred years, you've changed into such a strange outfit."
Aizen said indifferently, "All things become ugly before they evolve."
"You've merged with the Hōgyoku, haven't you?" Kisuke looked at the Hōgyoku embedded in Aizen's chest.
Aizen said, "Not merged, but the Hōgyoku has submitted to me."
"Submitted? Then let me see how far you've come."
Bakudō #61: Rikujōkōrō!
Six light fragments firmly locked Aizen in place.
"Still using such a low-level Bakudō to restrain me? Kisuke, what are you planning?"
Aizen didn't rush to break free, looking at Kisuke with interest.
"Such a low-level... you say?"
Bakudō #63: Sajō Sabaku!
Bakudō #79: Kuyō Shibari!
Chains wrapped around him, and nine dark Reiatsu sealed Aizen's eight sides and center.
"Limit of the thousands hands, respectful hands, unable to touch the darkness. Shooting hands unable to reflect the blue sky. The road that basks in light, the wind that ignited the embers, time that gathers when both are together, there is no need to be hesitant, obey my orders. Light bullets, eight bodies, nine items, book of heaven, diseased treasure, great wheel, grey fortress tower. Aim far away, scatter brightly and cleanly when fired."
"Hadō #91: Senjū Kōten Taihō!"
Several pink light beams attacked Aizen, causing a massive explosion in the air.
A Hadō #91 with the full incantation, unleashed by Kisuke was astonishingly powerful.
Aizen's figure vanished, reappearing behind Kisuke, and with his hand as a blade, he slashed across the chest of the turning Kisuke.
"That's why I said it was such a low level."
Aizen's head became visible, his body still enveloped in tangible Reiatsu, and he had grown shoulder-length hair.
Hōgyoku's third fusion state!
The Hōgyoku had become a part of Aizen's body and his power had reached the pinnacle of Shinigami.
"Burn, Engetsu!"
Isshin smeared blood on his lips, then spewed a large amount of flames from his mouth, attaching them to his Zanpakutō, and slashed towards Aizen.
Engetsu struck Aizen, instantly erupting into a wide-ranging blaze.
"Getsuga Tenshō!"
Isshin's Reiatsu mixed with the flames, breaking through Aizen's defense and leaving scars on his body.
Kisuke drew the Zanpakutō from his cane, and together they attacked Aizen.
Aizen blocked Kisuke's blade with his bare hand, completely unconcerned about his injuries.
The two retreated immediately after their first strike failed, each holding a chain wrapped around Aizen's hands.
"Playing such petty tricks?" Aizen scoffed.
A figure descended from the sky, it was Yoruichi, clad in specialized battle armor. She punched Aizen to the ground, then unleashed a barrage of punches like heavy rain.
Raiōken!
Ultra-high-speed pounding unleashed by developed pectoral muscles.
The shockwaves caused by Raiōken collapsed the surrounding ruined buildings, and Aizen was deeply embedded in the ground, with cracks appearing in the tangible Reiatsu enveloping his body.
"How about this?" Yoruichi looked at the motionless Aizen.
The next moment, a powerful Reiatsu erupted from Aizen. Yoruichi couldn't dodge in time and was directly struck.
Her body was sent flying, the battle armor covering her shattered completely, and blood seeped from her mouth, indicating significant internal injuries.
Kisuke and Isshin attacked together again, but were repelled by Aizen.
Seeing this, Ichigo wanted to go help, but a flash of white light in front of him made him stop.
"Don't disturb Captain Aizen's fight."
Gin held Shinso, smiling as he looked at Ichigo.
"We should just watch the show."
If Ichigo rushed in now, it wouldn't have any effect on the battle, which is why Gin stopped him.
On the other side, Yoruichi activated Shunko and punched Aizen. Aizen took the punch with his left hand, and the architectural ruins behind him were pulverized by the overflowing Reiatsu.
Then, he gripped Yoruichi's wrist, preventing her escape, and slashed with his Zanpakutō, severely wounding Yoruichi.
Kisuke and the others were about to continue their attack when a voice stopped them.
"Retreat!"
A giant pillar of fire soared into the sky, and Yamamoto appeared, holding Ryūjin Jakka.
The two retreated with Yoruichi.
Aizen did not stop them, turning to look at Yamamoto, who was engulfed in flames. "Has the Captain-Commander finally decided to act? It's a pity it's already too late."
"If you lose, the Gotei 13 will be completely dismantled."
Saying this, Aizen glanced at the still-existing dark domain. He was very curious how Shin hadn't dealt with Baraggan yet, given his strength.
"Don't be so arrogant, boy."
Yamamoto charged at Aizen, slashing across Aizen's body with his sword, raising massive flames.
Aizen's body shattered like a mirror, and a sword pierced Yamamoto's body from behind. Yamamoto, however, smiled, firmly grasping Aizen's right arm.
"Aizen, I've got you."
"Oh? Is it really me you've caught?"
"No matter how perfect Kyōka Suigetsu's complete hypnosis is, the Reiatsu of the Zanpakutō that pierced my abdomen cannot be mistaken." Yamamoto said with certainty.
As soon as his words fell, nine other towering pillars of fire rose, completely surrounding the two of them.
Jōkakuen!
"Your continuous fighting gave me a chance to set this up."
"Let's be buried in hell together!"
