Bleach: Watch Closely, This Is How You Use a Zanpakutō

Time flowed like a fleeting shadow, and before anyone realized it, more than a year had passed since the Shiba Clan's return to Seireitei.

During this long period, Kisuke Urahara and Mayuri Kurotsuchi had worked tirelessly—or, more accurately, under the relentless pressure and coercion of Masatsuki Aozaki.

These two eccentric scientists had managed to develop a groundbreaking technology, one with the potential to revolutionize the entire medical system of the Gotei 13.

It wasn't just Masatsuki's impatience that had been driving them forward, but also the strict oversight of an irritable and demanding Yamamoto.

"So, the 12th Division's experiment is finally complete? They now have a perfected method to restore Jūshirō's health?"

Inside the 1st Division's barracks, Yamamoto sat in quiet contemplation, his gaze fixed on his young disciple, who was beaming with confidence.

Nearby, Shunsui Kyōraku peeked out curiously, his eager eyes locked onto the two men standing before their old master.

Unlike his usual carefree demeanor, a rare seriousness filled his expression.

And his focus was entirely on Jūshirō Ukitake.

"Jūshirō can really recover?"

Hearing Yamamoto's words, Shunsui couldn't suppress the sheer joy on his face, even letting out an unrestrained laugh.
