Nyx and Pluto were both shocked at this scene as they knew that even if you destroy 1/4 of the magic circle, it'll still function just fine due to its self-rerouting function.
They couldn't think of any reason why would the ritual suddenly stop with just a single attack from him, 'Hmm? Single attack!?' Then a certain possibility flashed in Pluto's mind, "Could it be!?"
"What's happening, Pluto!?" Nyx asked in distress. A slight fear is already seeping in her mind after Kisuke did something out of their expectations.
Yoruichi already stopped pursuing Pluto and went beside Kisuke and Sona to defend them from incoming attacks. Pluto use this chance to fly beside Nyx and shared his guesses, "Didn't he just blindly sent waves and waves of his attacks earlier to you?"
"And? What of it?" While listening, Nyx released a vast amount of darkness to surround both her and Pluto. She wanted to make sense of the situation first before continuing her assault.
"You deflected it..." Pluto just gave her a hint as even he couldn't believe that Kisuke is capable of something like that, but that's the only explanation he could think of.
"Deflected... !? Wait! What!?" Nyx understood what Pluto is trying to say. She then tried to recall every attack that she deflected and indeed, some of them hit the magic circle below, "Are you trying to say that he predicted where I'm going to deflect his attack used that chance to destroy the ritual!? You do know how absurd that is, right!? That's not a prediction, but precognition! And besides, how was he able to destroy the ritual with just a few attacks! Didn't you say that it's almost impossible to destroy!?"
"That's the only possibility that I could think of... And besides, if he's capable of predicting the way you deflect his attacks, isn't he also capable of analyzing the magic circle in this short amount of time? He only needs to find a way to separate the Devil from the ritual and it'll effectively cease its functions..." Pluto stared at the three of them while explaining his reasons. The dark-skinned lady is eyeing both of them while the masked man is busy saving the Devil, "Nyx-sama... I know that it'll go against your pride as one of the primordial Goddess, but we have to use that... We don't know if they're also capable of escaping this space, but chances are, they do... We don't want enemies like them. They're too dangerous."
"Tch!" Nyx clicked her tongue loudly, 'That guy prophesized that it'll be a human who would stop their ambitions... But didn't that about to happen when you picked a fight with someone like him? In any case, we really can't afford to let him escape. His strength is nothing much, but his analysis is in a whole lot level, we don't know what else he's capable...' She thought to herself.
"Nyx-sama..." Pluto called out to her to hurry her decision.
"Fine!" Nyx then snapped her fingers and blood-red mist ejected from the walls of the dome. The mist spread in no time and reached Kisuke, Yoruichi, and Sona, who's in the middle.
Yoruichi's first reaction when seeing this is to cast a barrier to separate them from the rest of the dome, "Bakudou no 73: Tozanshou (Inverse Mountain Crystal)." Yoruichi created a pyramid-shaped barrier around them.
What she didn't expect, however, is when the mist touched the barrier, it eroded it instantly, "!?"
This also instantly caught Kisuke's attention but they are already too late to react to it as it already reached them.
The moment the mist touched Yoruichi, she started coughing blood and crying tears of blood, "Yoruichi!!!" Kisuke called out to her in panic and grabbed her to his embrace.
"Gaha...! I'm... fine! I... can s-still... resist! Sona... she c-cant! Gah!" Yoruichi did her best to speak and closed her eyes to concentrate on resisting this poisonous mist.
The mist also reached Kisuke and Sona, although Kisuke has better resistance than Yoruichi, the poison is still strong enough to destroy several of his internal organs and blood seeping out from his mouth. Kisuke then started to use his Reiatsu-Ki to eject this poison but instead of ejecting it from his body, he was only able to push it away slightly and most of his Reiatsu-Ki were consumed by the poison, 'What's this!?'
Sona, on the other hand, started coughing blood even unconscious and all of her orifices were seeping with blood. In addition to that, her skin is starting to turn black from her limbs. At this rate, she would only last for the next 10 seconds.
Seeing this, Kisuke instantly made his decision and chopped Sona's two arms and two legs before injecting her with his own Reiatsu-Ki to help her resist the poison and close the wound he inflicted her.
Kisuke didn't just chop off her limbs, but he also chopped off its soul body counterpart as he noticed that the poison affects the soul the most. When he looked at the limbs on the ground, it was already reduced to black ashes.
Kisuke next step is, he took out white pills and ate a few of them. He then faced Yoruichi and passed the pills to her, "Eat this first."
Yoruichi didn't respond but Kisuke still shoved the pills made out of pure Reiatsu-Ki he gathered using the power generator he had on the training ground to her mouth. Since he doesn't know the properties of the poison and doesn't have any time to study it, he could only fight it crudely, by drowning it with Reiatsu-Ki.
There are still two minutes until the Descorrer he set earlier to split open the space, but he couldn't wait that long anymore. His focus is already divided between resisting the poison for him and Sona and inspecting Yoruichi's condition every second, so he could only reduce this time for the Descorrer to take effect in 30 seconds. And so he did.
Nyx and Pluto were both dumbfounded at how Kisuke is still moving around and helping others resist the poison. They know how strong the poison is and it would only take a few seconds for it to kill them if they didn't take the antidote in advance.
"H-how?" Nyx muttered.
"Nyx-sama! He's really too dangerous! Let's kill him ourselves!" Pluto then took out his Black Scythe and flew towards Kisuke, slashing his back. But due to his Hierro and Shihakushou, he was only able to damage a few bits of his clothes and a small nick on his skin, "What!?"
He tried again and again but still failed to do any considerable damage. Even the special effect of his weapon doesn't seem to work on him.
Nyx followed suit and sent a barrage of magic bullets not only targeting Kisuke, but also the two girls beside him.
