Freya placed her 'heart' on her chest and fused with it, "Now that the terms have been established, let's do our best."
After confirming both of their oaths, Kisuke prepared himself. But before they could start, Freya added, "A prolonged battle between us would only uselessly exhaust us both so here's another proposition. If you can take on my strongest attack, I'll admit defeat. How about it?"
Kisuke didn't think too deeply about it and nodded, "If that's what you want, then I have nothing against it." Out of all the remaining things he wanted to measure, it's her maximum raw power.
Freya's smile deepened as she released the shield and sword from her hands. The weapons momentarily transformed back into cats before they transformed once again. This time, as a pair of metallic silver wings on her back, emitted motes of glittering light.
Kisuke could feel the surrounding Magic Power rush towards her and be converted to Divine Power just as fast. If not for him manually keeping the barriers, it would have been destroyed a long time ago. He then saw her raise her right arm once again and felt something descend once more.
As he looked up, Kisuke saw a 10-meter long and 4-meter wide pure white armored boar dashing straight to Freya with a loud roar that one could never believe came from a boar. Halfway through, however, the boar began shrinking until it became a sleek and gleaming white spear that landed on Freya's hand, "This is Hildisvíni, my most prized and most powerful weapon. It's also a weapon that wouldn't lose to Gungnir or Mjolnir."
Freya then lowered her stance and pulled back her arm that's holding Hildisvíni, getting ready to throw it at Kisuke, "Unlike Gungnir that always strikes true wherever the target is, however, mine would only go in a straight line."
"Then I guess it won't stop at any obstacle and would pierce through anything.", replied Kisuke with a chuckle and relaxed his control over his power, letting it quietly run wild inside his body. If he wanted to release the vast majority of his Hollow powers, controlling his base power would only limit it. Even though there's just a paper-thin division between his Shinigami and Hollow side, it's still a cliff-like separation.
He already concluded that he could fuse these two powers and without any doubt, he'd attain power that of a transcendent like what he had always wanted. However, he didn't choose to do so because he had a feeling that he would just throw Hougyoku's final efforts into trash. More than that, he also has an inkling that he might lose Benihime like how Aizen lost his Zanpakuto despite keeping its powers.
He doesn't exactly know what he's waiting for, but he's willing to use any time to bid for that exact moment that he could break through the invisible barrier of his existence as he wanted, 'I feel that I still need to go through many things before I could reach that state. I just wish I would never be backed into a corner that I would have to resort to something irreversible.'
Freya, on the other hand, also felt Kisuke's aura shift and stopped speaking to focus. The memories that Kisuke showed didn't reveal anything pertaining to his real strength, 'If he had to stand on the sideline as those two battled, I can assume that he's not on the same level.'
The main reason Freya proposed this kind of battle is to increase her chances of winning. Although Kisuke isn't on the same level as those ridiculous 'monsters', she couldn't forget Aizen's last words to Kisuke and how the former was tricked into receiving a sealing spell without his knowledge. She knew that if it's a normal battle, Kisuke's 'superior intellect' would take her down as it prolonged.
But even if she was able to force him into receiving her most powerful attack, she's still not very confident that she could win so in addition to her spear, she commenced employing her Magic to augment her spear further.
As the greatest and most powerful practitioner of Seidr Magic, Freya's forte isn't about the manipulation of elements nor the conjuration of mysteries, but the discerning the flow of time and working within its structure to bring about change, which was done by symbolically weaving new events into being. The sole reason why Freya could see through Ichigo's 'Mugetsu'.
That's also the reason why she was so terrified of that attack and the being that survived it. It's because 'Mugetsu' doesn't bring any changes, instead, it brought forth 'nothingness'.
After charging the Hildisvíni with as much power as she can, Freya diverted the rest of her Divine Power to her Magic which resulted in a golden Magic Circle behind her, infinitely more complex compared to everything that she has shown until now.
Borrowing and converging all the future that she saw into one event, Freya locked Kisuke into one singular result of him being pierced through by the spear powered by all the realities that she saw.
As Kisuke looked at this, a single drop of cold sweat ran through his back and he thought while his movements were being restricted by some invisible force, 'I've never thought that she would suddenly pull out a reality-warping spell. I could understand the restriction of my movements, but where the hell is this additional power coming from!?' From his point of view, it's as if multiple Freya's were stacked together, raising the power gathering within the spear exponentially.
And Kisuke's wild guess was correct. After collapsing the possible futures into one, the Freya of that timeline didn't disappear but temporarily migrated into Freya's position. It is a Grand Magic with power so great that it would render Freya's Divinity almost nonexistent for a period of time after this instance and further stay on the Lower World would risk her of its dangers since she wouldn't even have enough Divinity to return to Heaven if her avatar were to be killed.
In the event that Freya did actually die in this state, her consciousness would scatter without the guide of her Divinity. While she won't truly die, it would take countless years before she could wake up again.
This is truly her everything in one attack.
While it didn't normally happen, Kisuke became excited at this sight, 'Looks like gaining power meant one wanting to test it every now and then. Although only slightly, I can understand how Kenpachi feels all the time.'
Freya saw a deep smile crept on Kisuke's face and couldn't help but be bothered by it, 'Underestimating me?', she thought and said, "Be careful. I won't be able to receive my reward if you were to die."
"That looks really powerful... But I think I would have to disappoint you with an anti-climatic ending."
Freya didn't say anything else and just threw the spear saturated with Divine Power, "Hildisvíni!!!"
But before the spear could leave her hand, Kisuke disappeared and suddenly reappeared in front of her. For a split second, however, she thought an entirely different person appeared as the man in front of him had light blonde long hair that reached his hips. But that's the least surprising as he also grew a white angular horn pointing upwards on the left side of his head along with eyes with the blackened sclera and golden pupils.
Before Freya could react any further, Kisuke raised his left arm that was coated with Hollow material that reached his shoulder and grabbed the tip of the spear with his bare hands.
Freya watched her spear and Kisuke's hand made contact with unbelieving eyes. Releasing a bright white light, the shockwave that resulted from the collision of two forces instantly disintegrated all the barriers around, including the 'eyes' that were capturing their image. It didn't stop there as another wave of shockwave blasted almost half of the lake's water into space.
Thankfully, Freya's spear was pointing towards the vast sea as most of the force left that way and Melen and Orario were spared from total destruction.
Thanks to the disappearance of the barriers, Freya's massive Divine Aura spilled throughout the entire region, catching all the Deities' attention within it and making all of them release their own Divine Aura before making haste towards the source, except for Loki who's patiently waiting in her seat and Ouranos who couldn't leave in the first place as he had to strengthen his 'prayers' so this Divine Power wildly spreading wouldn't reach the depths of the Dungeon.
Normally, most of the Gods would have already recognized the source of Divine Aura as Freya, however, another unknown aura that was much more terrifying distorted any recognizable parts of the former. This unknown aura that was as strong as a Deity's aura if not stronger is more of a reason why everyone was scrambling to get to the lake. They wanted to know what ungodly being could be compared to a God.

Despite the blinding light, Freya could still see clearly what's going on and could only watch in disbelief as her spear's power slowly dissipated until there's only 1/100000 of it remained, leaving only some bleeding cracks on Kisuke's arm.
Freya's remaining Divine Power was exhausted and her armor, wings, and spear disappeared in a flash of light, returning where they came from, leaving behind the naked and unmoving Goddess to fall from the sky while muttering, "So you're just as ridiculous as them... I was scammed..."
Kisuke swooped her in while taking out a spare green haori and wrapping her with it before scooping her on a princess carry, "That's not my fault and I'm not on their level. Not yet, anyway."
