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

Three months later, in the Forest of Menos...

"Masatsuki-sama, is this really necessary? Once this is done, will I truly become an Arrancar?"

Harribel murmured softly, unable to suppress her unease as she felt the strange sensations coursing through her body.

The term "Arrancar" was something Masatsuki Aozaki had introduced to her—a title given to Hollows who had grasped the power of the Shinigami, essentially "Shinigami-fied Hollows."

Upon becoming an Arrancar, a Hollow's mask would shatter, revealing a human face, while their strength would undergo a significant boost. Some of their power would be sealed into a spiritual core, taking the form of a Zanpakutō.

However, the process of Arrancarization was an extremely dangerous experiment, one without any prior successful precedents for reference. Because of this, thorough and meticulous physical examinations were necessary.

Although she was wrapped in her sturdy bone armor, preventing direct contact, Harribel still felt a faint sense of embarrassment when Masatsuki Aozaki's hand touched her. Beneath her mask, her face tinged slightly with warmth.

"The Arrancar experiment has proven successful for Adjuchas, but when it comes to Vasto Lorde, we still lack sufficient experience. Naturally, caution is essential."

Masatsuki Aozaki waved his hand dismissively before turning toward the two young girls behind him and giving instructions.

"Loly, bring me the examination report. Menoly, take Harribel to rest."

Upon receiving the command, Loly Aivirrne, the black-haired girl with twin ponytails, swiftly retrieved a document and handed it to Masatsuki Aozaki.
