Chapter 70 - Full Out Assault

'I control it…'

'This power...I will use it like zangetsu.'

'I will save Nel.'

'I will stop Aizen.'

"Aaaagghhhh!!!!" Ichigo roared into the sky. Half of his mask began to shatter as his reiatsu flared wildly, kicking up a large vortex of sand. Eventually, his reiatsu stabilized as half of his mask crumbled. The vortex died down and Ichigo stood looking down over the unconscious body of Nel.

"Kurosaki!" Uryu yelled as he and Orihime ran up behind him. Ichigo turned and faced them and they both stopped in their tracks. His reiatsu was unrecognizable and despite half of his mask gone, he still had the eyes of a hollow and his long orange hair. In his ċhėst was a large hole.

"Inoue. Take care of Nel." Ichigo said. Before either of them had a chance to say a word, he vanished with a loud boom.

----

"Itachi stay back. I'll deal with Aizen by myself! I won't let Aizen hurt anyone anymore!" Ichigo yelled.

"Kurosaki, that's enough." Itachi replied calmly as he reappeared next to Ichigo. "I don't know what happened in Hueco Mundo, but fighting Aizen alone isn't the answer. You may be stronger than before, but remember why you're fighting here now. This isn't like you, Kurosaki. You may have gained control over your hollow, but do not let the bloodlust that drives it drive you. Do not forget the others that helped you get to where you are, otherwise... you'll end up like Aizen."

"Ah, I couldn't have said it any better myself!" A voice said from behind them. Ichigo and Itachi turned around and saw three familiar figures.

"D-dad?" Ichigo questioned.

"So nice you three could finally make it. Fighting both Kurosaki and Uchiha would have been a spectacle of its own, but with you three also here, I can truly test my limitless power." Aizen commented with a smile on his face.

"Remember our plan?" Urahara said as he glanced over at Itachi.

"Yes...but would that work on Aizen in this state?" Itachi questioned back.

"I didn't expect Aizen to have adapted so quickly. But we don't have a choice anymore." Urahara replied.

"Just make an opening for me, and I'll thrash him with everything I got." Yoruichi grinned as she raised one of Urahara's armor pieces on her arms and legs.

"Kurosaki." Itachi said, catching Ichigo's attention as he was talking briefly to Isshin. "Right now, your power is the key to our success. Urahara has a plan but we need to give him time and create an opening. That's where you come in. Do you remember the formations I taught you in our training?"

Ichigo nodded as he looked at Itachi, with his eyes filled with determination. The five shinigami readied themselves and faced Aizen who was patiently waiting for them.

"Are you all ready?" Aizen said with his arms extended out, as if beckoning all of them to come at him all at once.

"I will start first." Itachi declared as he quickly began weaving hand signs. "Formation B!"

"Bakudo 21: Sekienton!"

"Fire Style Fireball Jutsu!"

As a black smoke quickly filled the area, from his mouth, Itachi exhaled a large and dense fireball that eclipsed Aizen in size. Aizen smirked as he extended one hand out to block it.

Aizen grabs the fire ball, singing his arm slightly but quickly squeezes down on it, dispersing it as an even more powerful fireball emerges from the black smoke. Aizen keeps his arm extended, his burnt hand quickly healing, as he prepares to grab the second.

Aizen's eyes widened as the fireball in front of him disappeared in a puff of smoke, being replaced entirely by Itachi's figure. An ethereal armored humanoid began to surround Itachi as he cut in front of him with the Totsuka blade, completely dislodging Aizen's arm.

Aizen jumped back, surprised that Itachi's blade could still harm him, when Yoruichi suddenly appeared behind him.

"Shunko!"

A bright reiatsu appeared to envelop Yoruichi as she kicked Aizen in the head straight down into the ground. Aizen quickly recovered and let out a burst of reiatsu around him, sending Yoruichi flying back. As his arm and head wound began to regenerate, a yellow chain sprung up from the ground and wrapped tightly around him. Both Ichigo and Isshin appeared next to Aizen with their zanpakutos raised.

"Getsuga Tensho!" Ichigo and Isshin yelled simultaneously.

A large wave of black and white reiatsu merged into one as the father son duo let out their attack, completely engulfing Aizen and creating a large explosion that towered over the entire Karakura Town. Before the explosion had time to finish, at the tip of his sword Ichigo began charging reiatsu as a red bright ball began to form.

"Cero!"

"Amaterasu!"

The bright red pillar of reiatsu was suddenly turned black as Itachi's black flames quickly spread throughout its highly concentrated spiritual energy before imploding upon itself.

From the side, Urahara was preparing his kido, that was intended to seal Aizen away. However, the black flames and reiatsu suddenly were dispersed and pushed away by a strong force as Aizen teleported behind Kisuke, cutting him in the back.

Everyone looked in surprise that Aizen had emerged completely unscathed and now even stronger. His appearance was similar to his last one but he had two pairs of massive wings like a giant white buŧŧerfly.

"Amazing attacks...each and every one of you. However, I have reached a level far beyond your comprehension. You are nothing but insects to me now." Aizen raised his spiritual pressure, causing the air to shake around them. With a swing of his blade, the ground erupted in front of them, bursting with his reiatsu as the shockwave from the swing completely leveled out Karakura Town.

"Oh? You're still standing, Uchiha Itachi." Aizen commented as Itachi stood firmly with his armored Susanoo, having blocked the shockwave with the Yata Mirror. Aizen grinned as he teleported in front of Itachi.

Itachi reacts quickly, slashing at Aizen with the Totsuka Blade and piercing his shoulder.

"Uchiha Itachi...your blade, it did not cut deep enough." Aizen commented as he knocked the Totsuka blade up and reached his hand at Itachi's neck, easily penetrating the Susanoo's armor.

"Tsukuyomi!"

Itachi and Aizen locked eyes, looking straight into his Mangekyou sharingan. Their eye contact was broken however, as Aizen grabbed Itachi's neck and gripped it tight, causing him to close his eyes in pain.

"Your eyes can no longer affect me. It's been fun, Uchiha Itachi. But if this is all you can offer me, I am disappointed. Goodbye Uchiha Itachi." Aizen said as he flared his reiatsu once more and cut Itachi's head off. Itachi's head rolled to the ground and Aizen let go of Itachi's body, letting it drop to the floor.

"Congratulations, Captain Aizen." Gin clapped slowly as he reappeared next to Aizen.

"Good, you're here, Gin. Open a senkaimon to the real Karakura Town." Aizen ordered.

"Of course. But what about Kurosaki Ichigo? I can still feel his reiatsu down there under all that rubble." Gin asked as he opened the Senkaimon.

"He no longer interests me. Let him live for now, he's fulfilled his purpose." Aizen replied.
