At some immediate point, others also noticed this giant shadow that was looming over them, and like Aizen, they were stunned and were trying to figure out what they were looking at.
However, one thing is clear. The hand that was reaching out for them appeared to be way larger than they initially thought. As it approached them, it became certain that just the palm itself was enough to cover the entire Seireitei which is approximately around 700 miles in diameter.
Since it's such a massive thing, even those who are below have noticed its existence, and just like those who first noticed it, they could only stare at it in quiet awe and trepidation.
Naturally, the battle-hardened ones are the first to react, and even Aizen himself is prepared to intercept the ominous hand.
But before they could do anything, Serafall shouted, "Stop! Don't do anything!"
Everyone looked at her with confusion but at this point, Serafall already gained enough rapport and trust that they listened to her strangely dangerous instruction.
However, this didn't mean that they'd let their guard down and kept releasing their enormous amount of Reiatsu that any normal Shinigami caught up in this wouldn't be able to move.
While watching the arm extend with anxiety, they all felt a bit of relief when they saw a thin golden film manifested and stopped the hand's advance.
The hand seemingly kept pushing forward from how it bent its fingers and the muscles on its arm moved. Nevertheless, it couldn't move even an inch forward and the thin golden film only glowed brighter.
"...The Flame of Hearth's Protection," Serafall muttered to herself.
"Flame of Hearth?" Mayuri repeated her words, "Wait, before that. Do you have any idea what that thing is?"
Serafall shook her head, "But I know what that golden film is and it came from her." She answered while giving a glance towards 'Hestia' who still has her eyes closed and praying.
"She's not capable of fighting, but when it comes to protecting a designated territory, she's the best."
A few seconds later, the boundary of space where the arm came out was further torn up, revealing more of what's behind such a monstrous arm full of eyes with two pupils.
A vaguely skinny humanoid form and just like its arm, it's littered with eyes at random intervals. The only part that has a remotely recognizable pattern is the part where the face supposedly is. Different from the rest of the eyes from the rest of its body, it has 7 remarkably bigger eyes with one of them having additional features, arranged in a symmetrical fashion with three eyes on each side of the face and a single, bigger one in the middle vertically and that bigger one has three pupils on it going around chaotically and wildly.
"...Just what the hell is that?" Shunsui muttered with a very disturbed tone, not really expecting an answer.
However, Ouetsu gave a reply and it was a reply that no one was expecting, "...Hyousube Ichibei."
It was also at this moment that the situation drastically changed when Flanna, Ophis, and Lilith appeared beside them but instead of talking to everyone, they stared intently, not at the giant black figure but further beyond it.
From the depths of the Dimensional Gap, it appeared. A being a bit smaller than the black giant. Adorned with giant horns traced with red light. Skin that assumed the same tint as its light blue hair. Bulging arms that are covered in dark blue and red stripes scales that also extend to what seems to be Dragon wings and at the edge of these wings are more horns acting as curved blades due to how sharp they look.
Finally, its lower body is covered with dark sludge that doesn't fall off and a long, wide Dragon tail is attached to its back, also assuming the same color as its horns.
It was vaguely humanoid in form too, similar to the black giant but with its monstrous form, a mouth that extended towards its neck while revealing several rows of sharp teeth and clearly distinctive beastly roars that convey madness, it was nothing but a 'beast' empty of intelligent thoughts.
Strangely enough, Serafall managed to ignore all those features and was attracted to its eyes devoid of any humanity and only filled with its will of destruction, "...Ki...Kisuke?"
While everyone heard her, nobody could give her any attention as this monstrous being opened its mouth wide and took a bite at the black giant's neck.
The black giant ignored the beast that sank its teeth into him and kept pushing its hand. However, at some immediate point, the black giant seems to have noticed that something was amiss and all of its eyes in its body creepily turned towards it.
The black giant then moved its other hand and grabbed one of the arms that had been digging into it. With a single swift movement, the black giant yanked it out of him.
But instead of dragging the 'beast', it kept on chewing at him while its arm was instantly torn away from it.
It appears to be that the black giant finally realized the gravity of its situation and took back the hand that he had been pushing and used it to grab one of the 'beast's' horns. Although he was able to twist its head back and forth, it discerned that the 'beast's' head was strangely sturdy.
Flanna saw her chance and immediately released her Draconic Form, "Little lady, Open it up for a bit!"
She was referring to 'Hestia' and the latter understood what she wanted to do.
As soon as a small hole appeared on the golden film, Flanna shouted while spreading out her wings, "Blackie, little Blackie, push them away!"
Ophis and Lilith nodded and held each other's hand before extending their free arms to the sky. In the next second, a Magic Circle appeared on top of them before a beam of black light emerged from it. The shockwave from the light almost demolished the Sokyoku Hill but it was able to hold out with Aizen countering the recoil.
The beam of black light went through the golden film and the tear in the space, hitting the black giant.
The black giant tried blocking it, but without any proper foothold and being unable to assume any counter, it was blasted away along with the 'beast' on its shoulder until they were just a speck of dust in the depths of the Dimensional Gap.
Flanna then clapped her hands, releasing massive amounts of Draconic Aura. As her aura washed over the surroundings, the torn-up space started healing and this wasn't just limited to the Soul Society as the same thing was felt and observed on the other two worlds.
Flanna took a deep breath and turned to the stunned audience, "Whatever you're doing, make haste before those two return."
