Harry Potter: Toji Potter

The dimly lit room in the back of Urahara's Shop had an atmosphere of brewing chaos. Harry Potter leaned back on a plush chair, his usual gentlemanly demeanor intact, while Kisuke Urahara scratched furiously at a notebook filled with calculations, diagrams, and what looked like hastily scribbled jokes.

At the center of the room, Yoruichi, in her small, black feline form, lay curled on the table. Her sharp eyes followed the men's animated discussion, her ears flicking with each outlandish idea.

"I'm just saying, if we create a modified Garganta reinforced with Quincy reishi principles, we could ensure structural stability," Kisuke began, twirling his fan.

Harry nodded. "True, but what about layering it with a counter-resonance to their natural energy fields? Makes it harder for any Arrancar to sense us coming."

Yoruichi's tail twitched. What in the hell are they even talking about?

Kisuke grinned, eyes alight with excitement. "And if we introduce a spiritual decoy... say, an enormous fake reiatsu signature shaped like a giant dragon…"

Harry smirked, raising an eyebrow. "Why stop at one? Let's make it two dragons. One hollow-based, one Quincy-based. Keep them guessing."

Yoruichi's feline jaw nearly dropped. Before she could even process the audacity, Harry leaned back further in his chair, the motion calculated yet relaxed.

"Oh, and we'll need an upgraded Hogyoku for me," he added casually.

Kisuke paused mid-scribble, staring at Harry. "You're not serious."

"I'm always serious," Harry said, placing his hand over his chest. "It's for science."

The conversation escalated further as Harry described how he planned to imbue his new Hogyoku with divine magic, and Kisuke gleefully theorized how this could push the boundaries of soul-reformation.

Yoruichi couldn't take it anymore. With a sudden shimmer, she transformed back into her human form, the transition seamless but leaving her naked as her feline form didn't require clothes. She sat cross-legged on the table, utterly stunned, her golden eyes wide in disbelief.

"You two are insane," she finally said, voice sharp with exasperation.

Harry didn't even flinch, offering her a serene smile. "Insanity is a matter of perspective, my dear."

Yoruichi sighed, pinching the bridge of her nose. She didn't even bother covering herself; her dignity was the least of her concerns right now. "Do you ever stop coming up with plans that could potentially break the fabric of reality?"

"Not if we can help it," Kisuke said cheerfully.

A few hours later, after more planning and fine-tuning, Harry stood in the center of a ritual circle etched with runes and spiritual matrices. In his hand, two newly created Hogyoku orbs pulsed faintly, one glowing blue and the other shimmering violet.

With a deep breath, Harry fed both orbs his divine magic and Soul King candidate reiatsu, merging them into a single entity. The resulting orb floated upward, glowing with a radiant, otherworldly light.

As it hovered before him, Harry spread his arms wide, welcoming it into his chest. The orb pierced through his body, merging with his soul. His elegant attire rippled as if caught in an invisible wind.

When the light subsided, Harry's appearance had changed. His suit was now black, accented by faint, glowing streaks in the Hogyoku's colors. His shirt collar was open, revealing a faintly glowing orb embedded in his chest. His once-immaculate top hat had dissolved into his hair, which now flowed longer and more untamed, reminiscent of a warrior in the prime of battle.

Kisuke stumbled back, overwhelmed by the pressure rolling off Harry.

"Your spiritual pressure… It's like nothing I've ever felt before," Kisuke muttered.

Harry merely smiled, his calm demeanor unbroken. "Power is merely a tool, Kisuke. What matters is how we use it."

The next day, Harry and Kisuke donned coats designed to conceal their energy. Harry, preparing to open a Garganta, reached out to his Hollow Zanpakuto, Tenshō no Kagami or Kagami for short.

"Your assistance, please."

A regal figure appeared before him, the manifestation of his Hollow powers. Kagami had the lithe form of a Vasto Lorde, her appearance both graceful and wild. She wore a flowing robe that seemed to shimmer with an otherworldly iridescence, accentuated by streaks of gold and black. Her mask fragments framed her sharp, angular face like a twisted crown, and her hollow hole glowed faintly at her collarbone.

Her voice was smooth yet commanding. "What do you require, Master?"

Harry inclined his head. "Teach me to open a Garganta properly. One fitting for our mission."

With a flick of her hand, the air before them rippled and tore open, revealing the vast expanse of the Garganta.

The space inside the Garganta was breathtaking. A dark blue expanse stretched endlessly, dotted with star-like lights that flickered gently. Harry and Kisuke constructed a Japanese-style walkway of reishi beneath their feet, each step resonating with a faint hum.

"This is… beautiful," Kisuke murmured, glancing around in awe.

"Even chaos has its moments of tranquility," Harry replied.

As they exited, the world of Hueco Mundo spread before them—a stark desert under an endless moonlit sky. Kisuke adjusted his hat, scanning their surroundings.

"We're in the Forest of Menos," he said. "A perfect place to start gathering intel."

Harry smirked. "Then let's not keep our enemies waiting."

Together, the two ventured into the depths of Hueco Mundo, their journey just beginning.

AN: Harry's Zanpakuto Powers and Abilities:

Name: Tenshō no Kagami 

Powers and Abilities:

Kagami has many Powers and here they are: It's an Elemental type,

when released, his Zanpakuto transforms into a mirror-like blade that can manipulate and reflect various elemental forces such as fire, water, wind, and earth. This makes him incredibly versatile in combat, as he can adapt to any situation.

Abilities in Shikai:

"Katon: Hōka no Kagami" (Fire Style: Mirror of Flames): The blade can summon and control fire, allowing Harry to launch powerful fire-based attacks.

"Suiton: Mizunami no Kagami" (Water Style: Mirror of the Abyss): The blade can manipulate water, creating torrents and water-based defenses.

"Fūton: Kaze no Kagami" (Wind Style: Mirror of the Winds): The blade can control the wind, allowing Harry to create powerful gusts and wind-based slashes.

"Doton: Tsuchi no Kagami" (Earth Style: Mirror of the Earth): The blade can manipulate the earth, creating barriers and launching earth-based projectiles.

Due to so many variations of his Shikai, he has to say specific words to enter a selected mode of his Zanpakuto (though with Bankai learned, he can go into Shikai wordlessly):

"Ignite, Mirror of Flames!"

"Flood, Mirror of Abyss!"

"Gale, Mirror of Winds!"

"Quake, Mirror of Earth!"

Bankai: Harry's Bankai is named "Tenshō no Ryūsei" (Meteor of the Heavens). In this form, the mirror blade shatters into numerous shards, each capable of controlling a different elemental force. These shards hover around Harry, granting him unmatched control over the elements and allowing him to combine them in devastating ways.

Abilities in Bankai:

"Ryūsei no Honō" (Meteor of Flames): A massive firestorm that engulfs the battlefield, incinerating everything in its path.

"Ryūsei no Kōzui" (Meteor of Torrents): A powerful deluge that floods the battlefield, overwhelming enemies with water.

"Ryūsei no Kaze" (Meteor of Winds): A devastating tornado that sweeps across the battlefield, tearing apart anything in its path.

"Ryūsei no Daichi" (Meteor of Earth): A seismic upheaval that shakes the battlefield, creating massive fissures and launching boulders.

Here he needs various names for the moves as well:

"Blaze, Meteor of Flames!"

"Surge, Meteor of Torrents!"

"Tremor, Meteor of Earth!"

"Kagami," Harry said calmly.
