While overlooking the Adventurers who were doing their best to survive from afar, Serafall asked, "Is this alright?"
Yoruichi, who was sitting on some protruding ice, sighed, "It's fine. We can at least guarantee their lives."
As Kisuke had instructed, Yoruichi and Serafall returned to Orario and gathered the Adventurers of the top Familias and then tossed them into the depths of the Dungeon. Currently, on the 60th floor, an expansive world of ice and frost, The Ganesha, Freya, Loki, Hephaestus, Hermes, and Miach Familias were currently at war with 4-meter tall humanoid creatures covered in white and gray fur, Yeti.
In addition to these monsters' immense strength, they were also capable of using Ice Magic that was equivalent to a Level 4 Mage. On top of that, thanks to Yoruichi releasing her Reiatsu, some of them were mutated with each one of them equaling a Level 7 Adventurer, making the battle extremely hard despite the cooperation between Orario's top Familias.
But it wasn't just Adventurers and Yetis in the fray, as irregular monsters were also attacking both sides. Not just caterpillars but also mantises came up from the lower floors when the clash started, "Do you think they'll be able to deal with the master of these irregular monsters too?"
Yoruichi shook her head, "If its identity is as we've guessed, we'll have to move to clean that up. My only concern is if the owner of the Dungeon would be able to contain the battle without any adverse effects on the Dungeon itself."
All of a sudden, an unknown voice whispered to their minds, [If you're worried that the Dungeon will blast open during the moment of battle, I can provide a quarter of an hour of silence.]
Serafall and Yoruichi immediately stood up and fired up their senses to maximum but failing to find anything around them, "I'd really appreciate it if you gave us a warning before you speak up." Yoruichi replied with a frown.
[My apologies. You were on-topic and this expedition will lead you to the Dungeon's parasite. I figured you'd want my input and cooperation.]
A few moments later, Yoruichi relaxed a little bit and sat back down, "That's true... But if you're telling us this, does that mean that this 'parasite' is a Deity?"
However, the mysterious voice already disappeared without providing them any answers, 'It seems that's all we need to know.'
Still, Yoruichi couldn't understand why Kisuke needed to kill this 'owner' as it's the best card they could use against Chaos who they clearly couldn't trust, 'Once he's done with us, chances are he'll dispose of us. Kisuke knows this so why?'
"What floor is this parasite located on?" asked Serafall.
"Kuroka and I explored until the 79th floor before stopping, because the 80th floor was a completely new domain. It's as if it was not part of the Dungeon anymore. If I were to guess, beyond that."

After having a plentiful rest, Sona, Koneko, Irina, Akeno, and Line returned to the Dungeon. They'd already heard what their friends were capable of on the other side and they couldn't sit still. But even if they wanted to fight against a God-level opponent to gain experience, there's just none like that unless a God decided to descend.
But even though they had nothing to overcome as of now, they believed that there was still something they could do. As Kisuke had said, polishing the basics until it couldn't be perceived as a basic anymore was also one way of getting stronger.
"Haaaut!!!" Sona bisected five giant wolf monsters with a single swing of her halberd. Looking at her blade covered with a thin coat of water that was moving several times that of the speed of sound, she thought, 'It doesn't break as easily as before. It also didn't consume as much stamina as before. The only problem right now is the headache-inducing sound it creates whenever it spins.'
Sona then looked towards her companions and saw Koneko spinning with her jet boots, blasting open skulls from the sheer force they produced.
On the other side was Irina, but unlike before, four pairs of Angel wings were attached to her back and unlike the normal ones, some of her feathers were colored red, giving the entire thing a nice hue against the overall whiteness. Though the most striking change was her halo. Instead of a golden one, she had a red one, presumably, it came from Great Red.
The light she conjured had also become red and she apparently couldn't change it anymore. The power of her light didn't increase much, but it gained the new property of 'Illusionary'. Whatever the shape of light she conjured, its existence will depend on her. If an enemy is hit by this light, Irina could decide whether this enemy was 'against the light', and then the one receiving the attack would take damage similar to Devils hit by Light Magic.
If it's an ally, various buffs could be imbued to those who were hit.
Sona watched as ten whips of light extended from her hands and melted the giant wolves around her, 'It looks incredibly versatile, but it has one glaring weakness. All of that depended on her perception and decision-making. One wrong choice and it could go bad, not just for her but also for those around her.'
Looking further away from her was Akeno. Like Irina, Akeno was also sporting four pairs of Fallen Angel wings, but also different from the former that gained an upgrade as an 'Angel', Akeno's limbs and the base of her wings were covered with black Dragon scales. She got an upgrade as a 'Dragon'.
As black lightning pierced through her enemies, Sona recalled their properties. Akeno's lightning also didn't get much of an increase in terms of destructive power, but they also gained a special ability which they decided to call 'Infinite Lance' for a very simple reason that it ignored any sort of defense to reach its enemy.
From their initial tests, there's still no type of defense it couldn't bypass, including barriers that separate space and time itself. It's incredibly powerful, but of course, it also suffers from some weakness as Akeno needed to perceive her enemies correctly for them to be hit. Aside from that, it's only effective against 'defenses' since they also tested that 'attacks' could collide with it and be stopped as Sona's 'water' defense was ignored, but when she shaped it like a blade and threw it towards her, the bolts of lightning were neutralized like they were just normal Lightning Magic that Akeno used to use.
And despite these upgrades on them, they were still actually the weakest among the group that came from the other side. Sona could break through any defenses and become essentially undying if she were to transform her body into a non-corporeal form.
Koneko had the most destructive power and could constantly be at her peak by absorbing Magic Power and Ki from the atmosphere, which basically made her a cannon that has unlimited ammo.
Kuroka has the most versatility with her use of Magic and Ki. She also has an amazing defense thanks to her 'Black Flames' that expel everything. If she's with Koneko, the two of them could complete a circuit, and both gain 'Absorption' and 'Expulsion' abilities of their flames.
Medusa had returned to her roots and even accepted the 'evil' within her, acquiring power that was unachievable to most Gods.
Serafall was already at the level of a Super Devil but for her to fully transform, she only needed one more catalyst.
Finally, Yoruichi. Like Kisuke, she was very secretive about her abilities, but Sona heard from her sister that she had no way of winning against her.
