Serafall reappeared in the mansion they bought when they first arrived in Karakura Town. This is where she set up the central management system for the Teleportation Magic Circles that she deployed throughout the world whenever she had free time. When things that Kisuke was planning got too involved with Hell, she thought that this was a good idea in case the conflict spilled out from their intended targets, and it turned out that it was one hell of a good idea.
A few minutes later, while monitoring the progress of evacuation, she felt that Kisuke's presence disappeared and knew that he left to finally end all of this, 'But is it really that easy?'
As she asked herself that question, she thought back to the meeting that Kisuke leaked to her earlier, 'He was forced to rely on them, and thanks to that, his negotiation powers have been thrown to the trash. I have to do something to at least get back some of that.'
True to her former position and job, Serafall started thinking of how they'll be able to get benefits and possibly gaining their alliance after all of this is over, 'For starters, how about I let a few ghost cities be destroyed? If I ask the Belial House, they should be able to export some of the Underworld technologies for repairs.'
Serafall further analyzed the management system and found that there are some disruptions in the flow of the Magic Power surrounding the areas, 'They're near, huh? Probably in two or three days? We still have plenty of time to prepare.'
She's also aware of those against the forced evacuation, but she figured that it'll soon be sorted out once the maggots make their way to the Human World.
"I guess I can leave this alone for now." After setting up all kinds of alerts, Serafall stood up and stretched her limbs before teleporting herself away. Her destination, the isolated space that they had within the Valley of Screams.
As soon as she arrived within the room designated for transfer abilities, she was greeted by various auras, and most of them are familiar to her. However, what caught her immediate attention was the intense and arrogant aura that seems to fill the entire space, 'And it doesn't look like they are making any effort in releasing that aura... How dangerous.' Serafall thought to herself with a single bead of sweat dropping on the side of her face.
'According to the profiles I have, there's only one person who fits the description. Isn't he teaching Ophis-chan how to use her Zanpakuto?' Serafall decided to take a look. As she went through the mansion, she made no effort to hide her presence. Although no one really bothered to approach her since they all have a lot more things that they have to take care of while Kunou and Tanis were busy bringing Claire back to health.
Naturally, Aizen and Ophis also felt Serafall's approach, but both of them are focused on the two blades that are on Ophis' hand right now, "I was wondering why that man asked for my help instead of the Sword God to teach you how to use them... But it turned out like this."
Ophis looked up at him and tilted her head, "...What seems to be the problem?" She also wanted to use her Zanpakuto to complete her 'cosplay,' but she and Lilith refuse to call the names that have been appearing in their minds for the simple reason that they didn't like it.
"Those swords are trying to call to you yet you're rejecting them. They are essentially dead blades." Aizen answered her seriously.
Ophis tossed one of the Zanpakuto back into the void and inspected the remaining one by pulling it out of its scabbard.
At that moment, Serafall arrived, and the first thing she did was to introduce herself, "Nice to meet you. I'm Sitri Serafall. Currently Urahara Kisuke's partner in crime."
Aizen glanced at her, and thanks to his experience, he was able to gauge some of Serafall's true ability, 'Another form of immortality, huh?' He knew that Serafall didn't receive Ophis' snake and immediately activated his Kyouka Suigetsu. Although he really can't control the illusions that he shows now after his fusion with his Zanpakuto, the benefit is that he could always activate it for whoever is looking at him.
"Aizen Sosuke." Aizen simply replied.
All of a sudden, the temperature around them instantly dropped, and icicles started forming in the surroundings. And when Aizen traced the source of the coldness, he immediately found out that it came from the crown of ice that abruptly appeared on top of Serafall's head.
"That won't work. I have various defenses etched directly on my consciousness." Serafall explained with a fearless smile on her face, "Your ability targets the opponent's brain directly. Unfortunately for you, inside my skull isn't exactly a brain made out of fat, water, protein, carbohydrates, and salts. There's only pure ice in here," she added while pointing at her head.
Aizen was silent for a few moments before speaking up, "Amazing... You're the second person to just directly disregard Kyouka Suigetsu. As expected of that man's partner. You don't disappoint."
"Then you'll probably be more impressed if you were to meet my friends. Sirzechs-chan will just directly destroy that ability while Ajuka-chan will immediately know that something is wrong with his formula. Flanna-chan... Well, she sees the world differently so I doubt you can hypnotize her without understanding her perspective. Hmmm... Who else?... Ah. Probably Shiva-chan too. There's hardly anything that can fool his senses."
While listening to Serafall, Aizen's eyes widened. All this time, he hasn't really met anyone who could go against his Zanpakuto save for Ichibei, who has power over all Zanpakuto, Kisuke and Kurotsuchi, who have countless tricks under their sleeves. Yet this time, there are multiple individuals who rendered it useless.
"So why did Ki-tan ask you to help Ophis with this instead of the sword guy?" Serafall changed the subject.
Aizen turned his eyes back to Ophis, "Nimaiya can fix and reforge a broken Zanpakuto. However, her Zanpakuto isn't broken, nor is there anything wrong with it. She just needs a closer connection with its spirit."
"...Doesn't that mean..."
"If it's getting 'closer' to a Zanpakuto Spirit, I'd like to call myself experienced." Aizen added with a smirk.
