Seems kind of dead

Yoruichi narrowed her eyes and quipped, "You really don't miss a single chance to humiliate people."

Yuko chuckled. "I'm only telling the truth."

The two of them: Your truth has hurt quite a lot of people.

Yoruichi and Isshin Kurosaki did not dare speak again, afraid that she would belittle them along with everyone else.

Isshin Kurosaki laughed and scratched his head. "I knew you had everything under control, Yuko!"

Yuko gave him a strange look. "Then what were you doing so early this morning? Could it be you wanted to reminisce with your Vice-Captain?"

Isshin Kurosaki: This woman really doesn't leave anyone an opening.

Yoruichi said solemnly, "The Hollow inside Ichigo Kurosaki does indeed require Yuko's attention. A monster of that level isn't easy to control completely."

This was not purely a matter of strength.

After White Hollow self-destructed, strength no longer mattered much to him.

But Hollowfication experiments were not so crude.

As one form of soul, a Hollow was essentially injected into a Soul Reaper's body—in other words, into their soul—during a Hollowfication experiment.

Soul Reapers and Hollows were both forms of souls, but they were complete opposites.

When two entirely opposite powers clashed, there was a chance of breaking through the boundary between Soul Reapers and Hollows.

Yet when the two souls merged, they often failed to produce the desired result.

That was why Aizen and Kisuke Urahara had spent so many years researching the Hogyoku.

White Hollow, whom Masaki had killed back then, entered Masaki's body through his self-destruction, and was then transferred into Ichigo's body.

Whether it was the Hollowfication invasion Shinji and the others
