"Listen carefully."
"You are outstanding warriors who graduated from 'Peak Battle.' By the order of the clan leader, you are qualified to challenge the next instance dungeon."
"But the upcoming dungeon will be much more difficult. Before entering, you must memorize everything in the manual."
"This instance is unlike any before it. Everyone must follow the clan leader's instructions."
...
At the front of the plaza, Senju Yukika stood in the lead, while Hatake Shuma addressed the group with final instructions.
Today marked the launch of a new raid event—"Invasion of the Soul Society."
This world was completely different from One Piece or Naruto.
The location: the Soul Society from the Bleach universe.
The system had warned them that their bodies would be transformed into forms compatible with the Soul Society upon entry. Their strength wouldn't be affected, and there were many experiential paths to choose from in this dungeon.
Yukika had one goal: the Hōgyoku in Rukia Kuchiki's possession.
As for the others, they were to compete with the Gotei 13's Shinigami captains.
The documents in Yukika's hands detailed information on the captains' powers—for example, the duration of Tōshirō Hitsugaya's Bankai, and changes in power after other captains released their Bankai. These insights could give his people a slight edge in battle.
Of course, how much they gained depended on their performance.
Yukika had already crafted a strategy: follow Ichigo Kurosaki!
He would draw attention, and at a critical moment, Yukika would storm Senzaikyū and seize the incomplete Hōgyoku from Rukia before anyone else.
Without that fragment, Aizen wouldn't be able to merge his own Hōgyoku with the one created by Kisuke Urahara, drastically weakening him.
Still, the task was dangerous. Without Yoruichi's intervention, Ichigo would've been killed by Byakuya Kuchiki.
Unlike others, Yukika devised a unique strategy for his clan. While he and Ichigo created diversions, his clansmen would quietly infiltrate Shin'ō Academy.
He had no interest in playing by the instance's plot. What mattered was growth.
Given the current strength of the Senju clan, they stood no chance in a frontal fight against the Gotei 13. Even killing a single captain was a pipe dream. Missions like stealing a Zanpakutō were absurd.
Therefore, Shin'ō Academy became Yukika's true target. He would sneak his clansmen in, steal the Hōgyoku, and retreat.
It was a perfect plan.
Yukika also knew exactly when the instance would end. He didn't need his people to train in the Academy immediately—just get familiar with hand-to-hand combat and Kidō. After he exited the dungeon, they could return to cultivate further.
With luck, they might even snatch a few basic sealed Hollows. A worthy gain.
Once they were stronger, the dungeon could truly begin.
The instance opened.
Passing through the gate, Yukika entered the mystical world.
He didn't waste time. Sensing enormous spiritual pressure from afar, he rushed toward it.
The Soul Society was about to plunge into battle.
Thanks to the system's concealment feature, his team's spiritual pressure was hidden, making movement easy.
There was no doubt—the overwhelming spiritual pressure belonged to Ichigo Kurosaki.
At this stage, Ichigo had not yet trained under Zangetsu and was charging toward the Senzaikyū for the first time.
The Soul Society, reacting to this sudden disruption, wasn't overly alarmed. Deep down, they didn't truly want Rukia to die. It was just that the orders from Central 46 had to be followed.
Locating Ichigo, Yukika didn't interrupt his battle but instead snuck to the entrance of the Senzaikyū and hid.
In the original story, Byakuya and Ichigo would emerge from the Senzaikyū and confront one another. Yukika's move was to wait for Ichigo to draw away Byakuya, then rush inside and find Rukia.
Time ticked by.
Finally, with a roar, Ichigo appeared—bloody and furious.
Byakuya faced him.
This was the moment!
Taking a deep breath, Yukika unfurled his jet-black wings.
Stealing the Hōgyoku wouldn't be easy, but if he moved fast enough, it was possible.
Sure, the Hōgyoku was available in the system store, but it was expensive. Getting one through the dungeon was a more cost-efficient choice.
As the two began talking, Yukika darted forward like a shadow.
With his spiritual pressure masked by the system, Ichigo and Byakuya sensed only a breeze.
Charging ahead, Yukika locked on to Rukia's presence and sprinted.
The so-called Senzaikyū was a somber structure. Rukia, inside a cage, stared in shock at the figure approaching.
"Who are you? What do you want?" she asked, panic-stricken.
Yukika didn't answer. He simply placed a hand on the solid iron door and pushed.
The reinforced door creaked under the strain of his spiritual pressure and brute force.
In that moment, the system's concealment dropped!
Even Yamamoto Genryūsai in the Captain-Commander's office felt the violent surge in spiritual pressure.
This book's path was too wild.
In his Resurrección state, Yukika resembled a demon.
To Rukia, those massive bat-like wings and claws were nightmarish.
Someday, when the people of the Soul Society saw the Black-Winged Demon again, they would name him the true culprit.
Seizing the Hōgyoku and invading the Soul Society's sacred core…
Xiao Wu had been betrayed!
Crack!
With a final push, Yukika smashed the door.
He rushed to Rukia and ripped through the restraints.
"You…" Rukia, humiliated and powerless, could only watch as the man drove his hand into her chest.
Success!
The Hōgyoku was his.
As Rukia collapsed, a piece of her clothing fell.
Sensing the captains drawing near, Yukika smiled, and his figure vanished.
This was a valid method—forcefully acquiring dungeon items.
Whether it would ruin the Bleach storyline or cripple Aizen's power didn't matter to Yukika.
