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

Sōkyoku Hill, underground training ground...

Deep within the rocky forest, a fearsome presence stood tall.

Reiatsu poured out endlessly, as if there were no limits, surging like an unstoppable tide. An overwhelming power flowed into his body, vast and ceaseless.

For a long time, Masatsuki Aozaki had been pushing the limits of a Shinigami. But now, the slow growth of his Reiatsu had suddenly shattered some kind of barrier, accelerating at an astonishing rate.

"It's still rising..."

He flexed his hands, his expression calm, yet he could feel the faint tremor running through his body.

A transformation, invisible to the eye, was quietly unfolding from within the Hōgyoku, subtly reshaping him. His soul felt as if it were awakening, and even the essence of his existence was undergoing a profound shift.

Lowering his gaze, Masatsuki Aozaki looked down at his chest.

There, mysterious blue-violet lines, resembling veins, flickered faintly before beginning to spread, slowly branching across his entire body.

At the same time, every aspect of his being—Reiatsu, spiritual body, and more—was experiencing an unprecedented surge.

There was no doubt about it. The Hōgyoku had successfully absorbed the Soul King's right arm!
