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

"What a pretty lame Kaidō..."

Abarai Renji grinned and muttered, "If this continues, I might be the first person in history to die from being treated with Kaidō..."

Moyu didn't even use full strength, yet Renji's arm cracked again.

"Some cures are enough."

"Look at Kira Iziru, Ichiro Sukawa, and the others. They're all looking over here... with envy."

Hearing that, Renji turned to glance at them.

All of them looked terrified, bodies trembling slightly, instinctively inching farther away.

"You call this envy?!"

Renji shouted, eyes bulging. "No, no, stop treating me!"

"I think... I can hold on until we get back to the Spiritual Academy..."

Crack!

Another crisp sound. Renji's bone cracked again.

"Damn it... I'm not dying here!"

His miserable wails made even Moyu feel helpless.

Kidō is divided into Hadō, Bakudō, and Kaidō. Of the three, Kaidō is by far the most difficult.

Unlike the others, Kaidō doesn't even have a fixed scale of levels. The strength of a healer is judged solely by the effectiveness of their treatment.

[Your Kaidō has been disliked by others, triggering your competitive drive. You've comprehended the meaning of Kaidō: Flesh and Blood.]

As expected.

Scanning through the new understanding of Kaidō that emerged in his mind, Moyu nodded in satisfaction.

In that sense, Abarai Renji's injury wasn't in vain.

"In the future, I'm gonna become a captain-level powerhouse!"

Renji wailed with dramatic flair.

Those who heard it were moved to pity, and those who saw it nearly cried.

It was truly a miserable sight.

"Shut it."

Smack!

Moyu slapped him on the head, making Renji's vision blur and ears buzz.

The others, witnessing this, felt their fear of Moyu intensify further.

But what happened next completely shattered everything they thought they understood about Moyu.

A soft green light began to radiate from his palm.

Under Renji's horrified eyes, Moyu calmly placed his hand on the wound.

Hummmm—

Everyone's eyes widened in disbelief.

"Wait—did I just see that right?!"

"Moyu's Kaidō... it's working?!"

"This healing rate... how is that even possible?!"

Even Rukia, the one most confident in Moyu, blinked furiously and rubbed her eyes. The reality in front of her made no sense.

On Renji's arm, the torn flesh visibly regenerated at astonishing speed...

Muscle and sinew regrew rapidly, like mushrooms sprouting after rain.

Within seconds, the previously mangled wound was completely restored.

Renji stared blankly, touching his healed arm with disbelief.

"Hey... it's really healed..."

In mere breaths, the damage was gone.

This wasn't just from Moyu's enhanced Kaidō. Another reason was the nature of the wound.

When a Shinigami is injured, Reiatsu from the attacker becomes embedded in the wound. That lingering Reiatsu must be removed before healing can begin.

It didn't apply this time.

"Next."

Moyu didn't even let Renji recover from the shock before applying Kaidō again.

This, too, was a method of strengthening healing arts—and Moyu wasn't about to waste the chance.

Half an hour later.

With his Reiatsu depleted significantly, Moyu finished treating everyone's wounds.

Only then did he calmly check the new prompts in his system.

[Your Kaidō fully healed one person. Confidence increased. Comprehended Kaidō's Deep Principle: Regrowth from Severed Limbs.]

[Your Kaidō fully healed five people. Confidence doubled. Comprehended Kaidō's Deep Principle: Cleansing Reiatsu.]

The dramatic growth in Kaidō's effectiveness was a surprising windfall on this mission.

But Moyu wasn't celebrating.

Although the Spiritual Arts Academy mission had been a success, it had also revealed a new problem.

Aizen Sōsuke had clearly taken interest in him.

"Haaah—"

He let out a long breath, stood slowly, and looked back toward the path they had come.

His expression was tinged with melancholy.

Why is it so hard to just be a salted fish who minds his own business?

Moyu wasn't someone who liked making waves.

He simply didn't want to waste energy on meaningless struggles.

But now that the storm had reached his doorstep—he could no longer play dead.

Rukia, standing quietly beside him, noticed something was weighing on his mind.

She stared at him carefully, a hint of worry in her violet eyes.

"Rukia," Moyu said quietly, "I've made up my mind."

Rukia was stunned. "You mean...?"

"After we return to the Spiritual Arts Academy," Moyu continued, eyes resolute, "I'm going to apply."

Rukia's eyes widened. A certain guess rose in her heart.

"You're not saying..."

Moyu gave a small smile and nodded.

"Yeah. I'm applying for early graduation—"

"And officially joining the Gotei 13."
