Akiko seemed to think about the timing necessary for 400 years ago to be a good approximate time for this apparent Hollow uprising. A bit of a frown came to her face as she realized that was around the time she'd graduated from the Academy and as such she was nothing but a child herself. "I was a kid fresh out of the Academy back then... " she said this only made Noel's eyes widened. First to be so directly addressed by Raizen and then to go on to be told that the conflict she was currently participating in, had been part of something taking place long before she was even born. She had nothing to say about this. Akiko was then forced to look at this pair of individuals, as they claimed to have done something which should have taken a hundred years in only a couple of days... "Uh-huh, something like a 12,000 percent up time. That's..." she paused waiting to see what they'd actually done, because anything done in that sort of time which would be useful in this situation had to be something stellar. Beyond that she knew from her own experience that the little redhead was quite a good research partner to have around as she'd used the girl's expertise to help get Raizen out of jail. Still, the cat woman's eyes just widened as Raizen directly addressed the creature inhabiting the Captain of the 4th Division as Ojiisan.
After being called Ojiisan and being addressed directly the form of Okawa in the ice began to crack. Hollows overhead became visible with a few seconds as the shell of the former Captain of the 4th Division cracked and exploded. From within came a face which bore startling resemblance to Raizen's. White hair tumbled forward and reached shoulders as this massive creature with a human face came together. This human face was complete with blue war paint shaped like a giant crescent over swooping over the right side of their face. Anyone old enough to realize would know this face, as it belonged to someone who had been a rather important and startling Captain in centuries prior to this. As his body ripped out of the body of the Okawa Atsushi it pulled him apart and seemed to be a conglomeration of various people's body parts, including those of the fallen Kenpachi who had a large scar across his chest and random other limbs. It also had wings and a large claw like apparatus on its shoulder with a small glowing orb in that spot as well. It would be the face though, that had the attention of the golden eyed Captain of the Twelfth Division. In fact she was so startled she took several steps back blinking as if completely unsure of what she was seeing. "But... that's..." the recognition on her face seemed to be something rather strange and painful for her. Which made Benihime's attention shift from the girls on the ground to her panicky Captain. "Ano, you know him, Aya-tai?" she asked seemingly immune to the amount of tension currently in the woman. "Juuniibantai taichou, Kumori Mōryōmaru!"
Her statement made Benihime's left brow raise, and then she simply nodded. She supposed there being a proper scientist among Raizen's relatives was something that was bound to happen. She took from the woman's surprise that she'd known this man at some point before he'd become what he was right now, but that wasn't really important as the this massive Hollow of collective bodies began to speak. "Oh? Knew I was here did you?"
