Harry Potter: Toji Potter

The group crowded into Kukaku's cannon, the contraption shaking ominously as Kukaku barked out last-minute instructions.

"Hold on tight! If you mess this up, you're toast!" she yelled, lighting the fuse with a dramatic flourish.

With a deafening boom, the cannon fired, sending them hurtling toward the Seireitei's barrier at breakneck speed. The energy coating their bodies clashed against the barrier, creating a dazzling display of spiritual fireworks. The barrier cracked and shattered under their combined energy, but the resulting turbulence scattered the group in all directions.

Harry and Yoruichi landed far from the main Seireitei, tumbling into the outskirts. Yoruichi landed gracefully, while Harry stood up, brushing dust off his coat with an amused grin.

"Well," Harry said, smirking. "That was dramatic."

Yoruichi rolled her eyes. "You're the only one who finds near-death experiences entertaining."

Before they could regroup with the others, the air shimmered, and a massive structure descended from the sky. The Tenchūren, the royal palace of the Zero Division, landed with a thunderous crash.

Out stepped the members of the Royal Guard, each exuding immense spiritual pressure. At their head was Ichibei Hyōsube, the Monk Who Calls the Real Name.

"Well, well," Ichibei said, his voice booming. "You're the one with the aura of the King."

Harry raised an eyebrow. "King? Not sure what you're talking about, but I get the feeling this is going to be interesting."

The Royal Guard introduced themselves, their imposing presence filling the area. Despite their intimidating demeanor, Harry remained calm, leaning casually against a nearby rock.

"We're here to assess the situation," Ichibei said. "Your presence has disrupted the balance of the worlds. Explain yourself."

Harry gave a wry smile. "Disrupted the balance? I'm just here to help a friend. Kisuke Urahara says Rukia Kuchiki cannot die, no matter what. I trust his judgment, and so should you."

Ichibei stroked his beard, his gaze sharp. "You speak with conviction. Very well. We will ensure Rukia's safety during this... investigation."

Harry's grin widened. "Appreciate it. Now, if you'll excuse us, we have some chaos to stir up."

As Harry turned to leave, Yoruichi beside him, the Royal Guard exchanged bewildered looks.

"He answered nothing about himself," Kirio Hikifune muttered.

"And now we're guarding a prisoner?" Tenjirō Kirinji added.

"He's toying with us," Ichibei said, his tone grudgingly impressed.

With a flash of Shunpo, Harry and Yoruichi vanished, leaving the stunned Royal Guard behind.

Elsewhere, Ichigo landed with a crash, quickly orienting himself and making a beeline toward the Seireitei. His progress was halted by Ikkaku Madarame, the bald and brash Third Seat of Squad 11.

"You're not getting through here, kid," Ikkaku said, grinning. "But I'll give you a good fight!"

Ichigo wasted no time. Their blades clashed, sparks flying as the two fought with relentless ferocity. Ikkaku unleashed his Shikai, Hōzukimaru, transforming his Zanpakuto into a spear. But Ichigo's determination and raw power overwhelmed him.

With one final strike, Ichigo disarmed Ikkaku, leaving him battered but grinning. "You've got guts, kid. Go find Rukia."

Meanwhile, Harry and Yoruichi found themselves face-to-face with an unexpected visitor: Yamamoto Genryūsai Shigekuni, the Captain-General of the Gotei 13.

"Yoruichi," Yamamoto greeted, his tone even. "Why have you returned? And who is this man?"

Before Yoruichi could answer, Harry stepped forward, his aura calm yet unyielding. "I'm Harry. Just here to make sure no one dies who doesn't need to. Rukia Kuchiki, for example."

Yamamoto's eyes narrowed. "Her execution is justified."

Harry tilted his head. "Is it? Because I'm pretty sure she hasn't done what you think she has. But hey, why don't we spar a bit while we chat?"

Yamamoto's Shikai, Ryūjin Jakka, ignited in a burst of flames. "You dare challenge me?"

Harry raised a hand, chanting, "Finite Incantatem!" The flames sputtered and died, leaving Yamamoto momentarily stunned.

Relighting his Shikai, Yamamoto launched an attack, only for Harry to counter with his own Shikai, Tenshō no Kagami. The blade shimmered, reflecting the flames back toward Yamamoto in a controlled arc.

They exchanged blows, the ground trembling under their power. Harry alternated between using elemental techniques and playful banter, keeping Yamamoto on his toes.

Finally, Harry sheathed his blade, holding up a hand. "Enough. I'm not here to fight for real. Rukia's execution? It's a ploy. There's a traitor among you, and killing her is part of their plan. Let's play along and flush them out."

Yamamoto studied Harry for a long moment before nodding. "Very well. But I will not tolerate further interference."

Harry smirked. "Deal. Now, if you'll excuse us, we've got some invading to do."

As Harry and Yoruichi disappeared into the shadows, Aizen sat in his chambers, his calm demeanor masking his surprise.

"That spiritual energy... not a captain, not a Zero Division member. Who is he?"

He leaned back, his mind working through the possibilities.

No matter. The game was still in his hands—or so he thought.

With the group scattered and the Seireitei on high alert, the stage was set for chaos, revelations, and the ultimate clash of powers.
