Serafall returned to their house and saw that Kisuke and the girls were waiting for her and were raring to go, "Alright, calm down. Let's wait for things to develop first before moving on our own... And Ki-tan... Are you thinking of appearing too?"
"I already called Tiamat and she should be here after cooking late-night snacks for Benihime."
Serafall was stunned silent for a moment before saying, "...I think Beni-chan is having way too good of a life. Make sure you ask her to do some work too, alright?"
"I have already a few things lined up for her."

Benihime, who was already on her third day of nonstop gaming sessions, was disturbed when the door to her room opened and the smell of potato fries and its sauce. Immediately turning around with shining eyes, Benihime gratefully received the very appetizing plate, "Just in time~!"
"Kisuke is summoning me." said Tiamat, who was still in her child-like form but without her giant horns and with her long light blue hair freely swaying down her back.
Benihime started munching on her fries while saying, "I figured. With a commotion that big, he'll probably take this chance to confuse everyone. Imagine a very strong Shinigami with unknown abilities suddenly appearing? He longs for that kind of chaos."
"Are you not coming too?"
"Nope, no way. He's probably about to ask me to do something unreasonable so my free time is about to end so I'm going to be enjoying the remaining time I have left."

Three hours later, within the 1st Division's barracks, an emergency meeting was called when the sensors within the Research Institute started going off sometime earlier.
"Now that we're all here, Captain Kurotsuchi, brief us on the current situation."
Mayuri stepped out of the line and went into the middle of the room filled with heavy silence, "I've sent scouts to determine the real identity of these 9 pools of strange energy and as of now, we're able to confirm that these are indeed the precursors to the Doors of Hell manifesting. I've estimated that these doors will fully open within the next 10 hours."
"Why is it taking this long to open?" The Captain of the 8th Division, Yadoumaru Lisa, asked while fixing the position of her glasses, "All the previous instances of these only took an hour at most to open after they were detected. Well, the door that Shinji dealt with some time ago might be an exception."
Mayuri turned his head to her before answering, "It has to do with these doors' scale. If the previous doors only allowed 10-20 Beast of Hells to go through these doors may let hundreds or even thousands of them. Not to mention, the possibility that someone or some people would be leading them."
"You mean those Arrancars?" The Captain of the 4th Division, Kotetsu Isane, muttered.
Mayuri slowly turned his head towards her, but this time, with a slightly fed-up expression, "Don't be naive. Everyone who has reached Hell could be leading this horde."
Isane's eyes widened as a certain someone emerged from her mind, "W-wait... You don't mean..."
"Yes. That includes the former Captain who received the ritual to have their Reiryoku-dense bodies to be broken down." Mayuri immediately ignored her after saying his piece and turned back his head to Shunsui who was also making a difficult expression, "We've already confirmed former Captain Ukitake's existence beyond the door so it wouldn't be weird that either former Captain Unohana and former Captain-Commander Yamamoto to make their appearance."
With a glare, the Captain of the 7th Division, Iba Tetsuzaemon, asked, "Why are you implying that the former captains will be hostile?"
Mayuri didn't immediately answer him and instead talked to Shunsui while taking out his bug-themed smartphone, "With your permission, I'll release the information."
Shunsui nodded after looking at everyone.
And with a few presses, Mayuri sent out a document to everyone's assigned terminal while saying, "This testimony was taken by Lieutenant Abarai and was sent to Captain Kuchiki first before it was sent out to the Captain-Commander and me."
All the captains aside from Shunsui, Byakuya, and Zaraki took out their phones and opened the document that Mayuri sent to them. Since it isn't an unnecessarily long statement, it didn't take too long for everyone to finish going through it once or twice.
"I-is this true?" Asked the current Captain of the 13th Division, Kuchiki Rukia. However, she's also very curious about the last part which mentioned Ichigo's son, Kazui.
"The source of the testimony is the individual known as Sitri Serafall. I trust that everyone in this room already knows about her and the extent of her actions? I don't know how accurate her words are and I don't really trust them without seeing it for myself, however, the information she has provided us proved to be valuable enough that even the Zero Division took interest in it and are currently actively exploring it on their own."
"Sitri Serafall..." Soifon, the current leader of Onmitsukidou and Captain of the 2nd Division, muttered to herself, "We tried searching for her background and those around her in the Human World, however, we couldn't find anything. It's as if they suddenly appeared in Karakura Town one day. But that's not important right now. How's the threat analysis?"
"Very high." Mayuri answered, "Humans who are killed by the Beasts of Hell are sent directly to Hell. As you know, Hell is not included in the cycle of Souls. If too many Humans are killed by them, the balance of Souls between Soul Society, Human World, and Hueco Mundo will be disrupted once again and we'll be forced to do something drastic… again."
"Should we send a Captain to each door?" asked Hirako Shinji.
"No." Byakuya immediately refused, "We'll leave Soul Society too defenseless and if that's what they are aiming for, it'll be disastrous for us."
"But we can't have them rush out of these doors. Even if we can deal with all of them, it won't matter if they devastate the Human World." The Captain of the 9th Division, Muguruma Kensei, chipped in, "If we can't deploy a Captain to each door, then our next best option is to barge into these doors and contain the threat on the other side."
"But Hell's Punishment will immediately react the moment someone who's not supposed to be there comes in." Soifon pointed out, "A few of the Onmitsukidou sacrificed themselves to get this information."
"And that's where Kurosaki Kazui comes in." Mayuri joined their discussion.
