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

At that moment, Nelliel pouted and silently watched Masatsuki Aozaki from behind.

After seeing Cirucci off, Masatsuki Aozaki turned around—only to catch a glimpse of a green blur flashing past.

In the next instant, Nelliel shot forward with astonishing speed, leaving behind a clear afterimage before slamming straight into Masatsuki Aozaki's arms...

A loud crash echoed through the room!

Masatsuki Aozaki was sent flying.

"Masatsuki, you're too mean!"

A soft, sulky voice rang out as Nelliel, her head still adorned with her goat-like mask, nuzzled against Masatsuki Aozaki's chest and whined playfully.

She was so adorable that it nearly made his heart melt.

"Nell, get up first..."

Masatsuki Aozaki had been knocked back several meters, but to avoid wrecking Aizen's carefully designed laboratory, he used just enough strength to steady himself.

Of course, Nelliel hadn't reverted to her child form.
