After fending off several of Serafall's attacks, Kisuke finally figured out what's going on, 'Teleportation with ice as the medium?'
Normally, teleportation magic in the middle of an engagement is impractical due to its long cast time and delay. Meanwhile, teleportation through a specific medium is very limited and very easy to spot despite its speed, making it also somewhat impractical in high-level combat.
However, the current surroundings were Serafall's world. In this Kingdom of Frost, she could appear anywhere. With her Demonic Power fluctuating everywhere, it wasn't easy to spot her. In this dominion of hers, she disregarded the biggest disadvantages of teleportation magic and used it in combat effectively and started overwhelming Kisuke.
As a matter of fact, this is Serafall's core strategy against him as she noticed a few quirks of his. During their first engagement, Kisuke would always be careful with everything that was thrown at him and only after he'd gotten enough information to analyze would he actively counterattack.
Serafall knew that she couldn't do anything regarding his observation and analysis abilities, so instead of actively stopping his data collection, she instead opted to overwhelm it by throwing new things at him constantly, making him confused for a moment.
Of course, she also knew the 'weakness' of doing this, as Kisuke could just blow away the ice around him, creating a breathing space for himself. But Serafall knew he wouldn't do that, because she knew that he was already aware of the spell she'd prepared just in case he used a large attack that would make an opening for a moment.
However, as time went on, while Serafall still couldn't land any decisive blows, she could see that Kisuke was also slowly getting used to her attacks and it wouldn't be long until he broke out of her barrage, 'This won't do, the chances of any of my attacks landing a good hit are almost zero... Maybe I should use that...'
From the outside perspective, the audience could only see a disastrous snowstorm that engulfed the field and hear nonstop explosions and clashes of weapons. They could only take a glimpse of Kisuke and Serafall when their weapons met and created a shockwave, blowing away the diamond dust around them before the both of them disappeared, reappearing at a different part of the battlefield.
"T-this can't be true, can it?" Lefiya muttered.
"Are they perhaps Gods that are pretending to be human?" murmured Alicia while trying to stop the shaking of her hands. Except for Loki, instead of shock, every one of them was now displaying expressions of fear.
Loki was a bit worried about their mentalities, but she didn't say anything and just let them watch the 'sparring', 'In any case, this Serafall... She's almost on Skadi's level in terms of Ice Manipulation. And that Goddess of Frost and Ice was one of the stronger Gods.'
Their fierce clash went on for a few more minutes, until Kisuke was finally able to break through Serafall's cage and was able to fly high up, where her attacks couldn't easily reach him. However, that was also the moment Serafall was waiting for when she decided to go all out.
Contrary to the casual way she cast her signature spell, 'Celcius Cross Trigger', the moment Kisuke reached a certain height, Serafall gathered the majority of her Demonic Power, including the parts powering her Ice Kingdom.
As the attacks entirely stopped and the ice began to thaw, Kisuke instinctively knew that something big was coming and hurriedly descended to stop Serafall. Nevertheless, he was already too late when he heard her say with an uncharacteristically serious voice and expression, "Endless Night of White Hell."
A giant magic circle appeared below Serafall before it immediately released a shockwave. Although not as flashy as her signature spell, as the shockwave passed through things, everything went to a grinding halt, including Kisuke, who was instantly crystallized, 'Crap! An Absolute Zero spell!? Is she trying to kill me!?' Only his mind could work as he tried to defend himself from the freezing elements that are invading his body.
From the viewer's perspective, it's as if time had stopped. Kisuke couldn't even fall to the ground as the air around him became solid. As of now, only Serafall, Kisuke's internal body and light could move in this dead world.
Endless Night of White Hell. This was Serafall's trump card and the first time she revealed this spell to anyone. A spell that was only possible with her half a step to the ranks of a Super Devil which no one actually knew about.
The three Goddesses were dumbfounded as the power Serafall used could actually annihilate a group of weaker Deities without them being able to do anything to resist. Simultaneously, all three of them became extremely worried about Kisuke.
Hestia hurriedly turned to Yoruichi, who was also surprised at this turn of events, "Yoruichi-kun! Hurry up and stop them! Are they trying to kill each other!?"
Sona also turned to Yoruichi and said, "Please stop them, Yoruichi-san. They're going overboard."
However, Yoruichi just shook her head, "It's already too late. Even if I go to that place, I'll just be instantly frozen. They already pulled the trigger so let's just trust Kisuke to resolve this. Believe it or not, even if you tore that guy into pieces, he can still come out of it alive."
Astonished at her answer, Hestia protested, "This isn't the time to be joking around!"
Yoruichi wanted to say that she wasn't joking, but before her words could come out, something changed in the quiet and motionless world as everything started shaking.
Serafall, who had been watching Kisuke's condition carefully so as to not accidentally kill him and wait for him to admit defeat in the channel she'd connected to Kisuke's mind, was surprised at the sudden violent change. She lost control of her still world as an unimaginable force started invading it.
Kisuke, meanwhile, although frozen stiff, was resisting the extreme cold by burning himself from the inside. Although his organs were damaged from the clash of extreme temperatures, it's nothing that couldn't be healed by his Hollow Aspect's regeneration.
He could break away from this predicament if he were to release his Vasto Lorde form. However, he didn't really want to reveal his inhuman form to the Loki Familia because he has a feeling that it may backfire at his plans.
'If one way of brute-forcing it isn't available, then another one should do,' thought Kisuke as he gathered his Reiatsu-Ki and cast a certain Kidou for the first time ever since his reincarnation, also touching the world's Reimyaku (Spiritual Pulse or Ley Lines) of another world, "Hadou no 99, Goryuutenmetsu (Five Swirling Dragons of Destruction)!"
The world of silence shook as five crimson eastern Dragons descended from above Kisuke with deafening roars. It was the forbidden Kidou of mass destruction.
