Bleach: The Shinigami’s Zanpakutō That Unleashed Bankai On Its Own

It was completely different from the Shinigami Reiatsu and Hollow Reiatsu in Moyu's understanding. It felt as if multiple kinds of Reiatsu were intertwined, carrying conflicting and unique characteristics.

Intense curiosity drove him to reach toward the wounded man's body.

[Your Reiatsu has sensed the presence of a Vasto Lorde-level Menos Grande. Your spirit is excited. Your cultivation has broken through, and your Reiatsu has doubled.]

Hum—

Unohana Retsu noticed Moyu's actions, but before she could stop him, his palm had already pressed against Aramaki's body. In the next instant, a violent wave of Reiatsu surged out of Moyu, engulfing the entire ward and radiating outward in every direction.

"What a Reiatsu…" Yamada Seinosuke muttered with difficulty, despair flickering in his narrow eyes.

"So strong!" Madarame Ikkaku's eyes lit up. Like a beast sensing a worthy opponent, he became instantly excited.

"Mr. Moyu…" In the depths of Unohana Retsu's usually calm eyes, there was also a flash of battle-thirst. Along with Moyu's wild Reiatsu came the same wind that had once swept through his sword.

Realizing the danger, Moyu suppressed his own Reiatsu as fast as possible. The surge had been overwhelming, hard to control, but eventually, he forced it down.

Hah— Moyu exhaled deeply. "If I'm not wrong, Aramaki must have fought a Hollow before this."

Madarame Ikkaku's expression changed, becoming solemn. "That's right! After we received the emergency alert, I rushed to the South Rukongai's 39th District and found Aramaki. He was already on the verge of death. But what was strange… the Reiatsu at the scene wasn't just his or the Hollow's—there was Shinigami Reiatsu mixed in too."

Those words made the atmosphere in the ward tense.

"Defector Shinigami…" Unohana Retsu lowered her gaze, falling into silent thought. But in Moyu's eyes, a cold light flickered. Reiatsu, Hollow, Shinigami… chaos…

Adding in the system prompt from earlier, the truth became clearer. If nothing else, this strange mixed Reiatsu must be connected to Aizen. Or rather—to the Hōgyoku.

It was the Hollowfication experiments from a century ago that caused the tragic downfall of several captains and vice-captains, leading to Urahara Kisuke and Shihouin Yoruichi's exile from Soul Society. It also showed Aizen the terrifying possibilities of merging Hollow and Shinigami powers.

A Vasto Lorde-level Menos Grande appearing in Soul Society would usually cause immediate response from the Technology Development Bureau. Even if they couldn't detect the Hollow itself, they would sense the spatial fluctuations.

But this time, nothing. There were casualties, and still no reaction.

Which meant only one possibility—the Vasto Lorde wasn't from Hueco Mundo, but born within Soul Society.

Aizen Sōsuke.

Even though the man wasn't present, his influence lingered everywhere.

"…I really can't let my guard down yet." Moyu sighed and turned to Madarame Ikkaku. "From what I sensed, you might be able to use an intermediate-level Kaidō to cleanse the foreign Reiatsu, but it's risky. I don't know if you…"

Ikkaku froze, his forehead twitching with stress.

"…Just go for it, Mr. Moyu," Unohana Retsu's gentle voice broke the tension. Her eyes met Moyu's with calm trust. "I believe in you."

Pure, unwavering trust.

Moyu stared back, momentarily stunned. He had assumed Unohana's interest in him was limited to swordsmanship. But clearly, it wasn't that simple.

"I understand…" Without hesitation, Moyu pressed his hand to Aramaki's chest.

A soft emerald glow erupted, bathing the room in light. Like spring returning to a frozen world, the air was suddenly filled with the breath of life.

Massive spiritual energy surged from Moyu into Aramaki's body—like a king inspecting his territory, ruthlessly driving out the intruder with whip-like precision.

Moyu's eyes sharpened. His Reiatsu's nature was stronger than he imagined. Even the oppressive Reiatsu from a Vasto Lorde-class Hollow couldn't compare.

Within moments, he had forcibly expelled the foreign Reiatsu. Aramaki's own spiritual pressure began circulating again, repairing the damage.

"Ugh…" A low groan escaped the patient's lips as Aramaki slowly regained consciousness.

"…Where am I…?"

Madarame Ikkaku immediately leaned over, grinning ear to ear. "Haha! I knew your luck wouldn't run out, idiot. This is the Fourth Division General Relief Ward. You're saved!"

This strange, rowdy way of greeting seemed to be standard for Squad 11 members.

But Moyu remained silent, his eyes fixed on Aramaki with growing seriousness.

As the wounded man opened his eyes, a realization hit him.

Aramaki Makizō…

The strongest hidden force in the entire Soul Society. A god-tier existence equal to or beyond captains. The legendary…

True Five Special Combat Powers.
