Momo Hinamori was busily directing her comrades where to position themselves after receiving the memo from the 12th Division that there might be a big 'door' that might appear here.
While doing so, Momo suddenly felt the air around her slightly change and thanks to her being alert, she was able to detect the projectile that was aimed at her head and was able to dodge it. She immediately placed her hand on her sword and turned around to see a Human woman waving at her with a big smile, "Hmmm..!? That is.."
She was the same woman who snatched one of the Beasts of Hell that attacked them.
Momo tightened her defenses but saw the latter had no intention of attacking as she just sat down on the bench, '...An invitation to talk?' After she thought about it, the projectile has no power behind it nor any ill intent.
After making sure that there are no follow-up attacks. Momo released her hand from her sword and turned in her Captain's direction. Since Shinji is quite a distance from her, she had to raise her voice, "Captain!"
Shinji heard her voice and turned around to see his Lieutenant gesturing something at him, "Huh? Look at what?"
He followed the direction she was pointing at and saw a woman that was sitting on the bench while waving at him with a small smile, "Hmmm?" At that moment, Shinji recalled something and immediately pulled out his phone and tapped it a few times for it to display a certain image. He turned from his screen and to the woman and vice versa a few times before muttering, "It's her, huh? To think she'd show up here. There were no more sightings of them after their encounter with Ichigo."
The picture he's looking at was secretly captured by the Chief Editor of the Seireitei Communications and the Lieutenant of the 9th Division, Shuuhei Hisagi on the night of 'Hell's Assault'.
Shinji thought about it for a moment before walking towards Momo first and bringing her with him to meet the strange woman.
Serafall, on the other hand, started walking towards a place where no one could see or hear her.
Shinji and Momo landed in front of Serafall and since it was the latter who wanted to talk, she introduced herself first, "I'm Sitri Serafall. Nice to meet you."
Shinji's eyes landed on her stretched-out hand and returned her gesture after hesitating for a short moment, "Hirako Shinji, Captain of the 5th Division of the Gotei 13."
Seeing that, Momo immediately lowered her head, "I'm Hinamori Momo! The 5th Division's Lieutenant! Nice to meet you too."
Shinji let go of her hand and directly asked her, "Are you here to snatch one of those Beasts again?"
Serafall shook her head, "No. Of course not. I'm done with that. I'm just here because it looks like a large hole is about to open, but it looks like your group is enough to deal with anything that could come out."
Shinji's brows furrowed, 'She can detect these 'doors'?'
Serafall successfully guessed what he was thinking and nodded amicably, "I can. It's actually pretty easy if you can feel the strange thing that's pushing the Spiritual Power away."
Shinji and Momo were both stunned at her statement but before they could ask questions, Serafall continued speaking, "But I'm not here to tell you how to do that. I grabbed your attention because I want to ask what you're going to do with the people around."
"The people around?" Shinji parroted and looked around him to see blissfully unaware people, "There's nothing we could do about them. It's not like we cause a commotion since that'll only gather more attention after they initially run away."
Momo, meanwhile, could only bite the corner of her lips since it'll be hard to save them. The only thing they could do is to finish off their opponents as fast as possible to avoid unnecessary casualties.
"...I guessed as much." Serafall sighed, "Then do you mind if I do something about them? I promise that it won't impede your operation."
Shinji stayed silent for a moment before answering, "As long as you can keep them away within the entire duration of the fight. If you can't then forget about it. You'll only cause more deaths."
Serafall didn't explain herself any further and just raised her right hand over her head.
Shinji and Momo don't know what she was trying to do but when a giant circle of strange geometrical shapes suddenly glowed in blue and expanded from her feet to cover the ground, the Captain and his Lieutenant jumped back to the sky with alarm, and grabbed the hilt of their swords.
The other Shinigamis were also alarmed by this sight and thought that it was already the enemies attacking with each pulling out their blades from their scabbard.
Serafall ignored what they were doing and just continued her actions. Soon, the circle stopped expanding when it reached a kilometer in radius. A similar but just a few centimeters wide circle also appeared on top of her right hand.
Shinji and Momo have no idea what's happening and are considering if they should attack first, but the giant and small circle soon disappeared after releasing a soft light. The next moment, those who were enjoying themselves in the park packed their things and started leaving with blank expressions on their faces.
After seeing this, Shinji guessed what might have happened, "Hinamori, confirm what happened to all Humans in the area. Send multiple people out and give me a report immediately."
Still clueless, Momo answered before disappearing with a Flash Step, "Yes!"
Shinji slowly descended from the sky and landed in front of her again, "What did you do? And what were those magic-like special effects? Are you some sort of Magical Girl?" Shinji was reminded of his time in the Human World when he would sometimes binge-watch some anime shows.
At those magic words, Serafall's eyes instantly shone, "Yes! I'm a Magical Girl!"
Shinji thought that she was joking and Serafall intended to explain more when her mood suddenly went south.
Serafall slowly lifted her left arm and pointed her finger at one of the trees on her left. A Magic Circle appeared on the tip of her finger before multiple spears of ice abruptly manifested around her and rained down on the area she was pointing at.
Shinji immediately took some distance again from Serafall but she ignored him and just kept bombarding the area for a few seconds before stopping and leaving the poor trees and ground multiple holes in them, "I'm fine with you secretly observing since I'm doing this in public, but could you please stop that slimy and sticky stare?"
At that moment, Shinji felt a familiar eruption Reiatsu and saw a man with a strange head that looks like an antenna, "Kurotsuchi? What are you doing here?"
But just like the former, the newcomer also ignored him and directly talked to Serafall, "My... I'm very surprised that I was detected even with a potent Reiatsu-Concealing Cloak. As expected, you have an entirely different system of detection... The one that doesn't use any Reiatsu."
