[Demon king's Castle, Demon Continent]
Due to the sudden mistakenly guess in which Kaido thought that the Demon King would be staying in his castle walls, he instead goes to face to face against the Dark Knight of the Demon King who is believed to be same as strong as the vassals themselves
Currently that certain Dark Knight was going up face to face with four Calamity Class Beings also known as the four children's of Calamity
With the case of two different power going up against each other, the only solution to such situation is to either one of them survive or one of them dies
As Asuto started releasing his oppressive purple aura that filled the whole castle with a pressure that could shake the world, all four of the Calamity Class Beings became wary of him and started to heighten their own senses
With a tap of his foot Asuto instantly dashed ahead in a lightspeed as he easily bypassed the Calamity Class Beings senses and arrived before Kaido, arching his back, he came in to thrust his sword towards him but at that moment a smirk appeared on Kaido's face as the sword and the psychic barrier collided
With a clash of power an explosion suddenly rung out as the wall behind Kaido suddenly was blown away cause of the directed force of the sword which far surpassed the power of strength coming from Raguel
At that moment Fengris, Aileene, and Argos finally sensed Asuto's presence as they turn their head towards Kaido's direction
"Bastard!" Roared Fengris as he made a run towards Asuto while cursing for ignoring them
As for both Argos and Aileene they just kept silent as they made their actions do the talking with Aileene Tracking below and Argos stretching out his claws up above
With that Asuto's aura bursted out like a fan that slammed against the three Calamity Class Beings and blew them away by a few blocks, at the same time the aura on the tip of his purple sword suddenly became sharper as it started to pressure Kaido's barrier
Moments later a crack suddenly became visible as the sword was overpowering Kaido's barrier
With a click of his tongue the barrier finally broke apart and dashed straight towards his head, naturally at that moment Kaido tilted his head in time to only have it graze his cheeks as his body started to glow up red
With a bang a radioactive shockwaves suddenly slammed against Asuto the drew him backwards towards the door of the throne room, which indicates the shockwaves is much powerful than her aura wave that he sent
When he got far away, Kaido suddenly touched his grazed cheeks and could feel blood trickling down on its cut, with that he stood straight and glared at so called Dark Knight of the Demon King
"You... Just who are you?"
But instead of answering back Asuto once again stood up as he positioned himself to attack once more
With that Kaido once more asked
"No let me rephrase my question, what are you?... This aura is not Demon's aura nor any of its affiliated aura... Since you broke my barrier it means that your element's and matters are different from what I consider existent, that begs the question... Who and what are you?"
But even though with that explanation Asuto remained silent as he started boiling up his aura to rise to its dangerous level
With that Kaido just shrugged his shoulder as he said
"You don't want to answer? Fine then I'll just have to extract it forcefully from you"
Without any warning Kaido tapped his feet to send multiple underground attack towards Asuto
In his command black earthen spikes suddenly assaulted Asuto as it seems they are trying to reach out to him
With it Asuto quickly jumps up to the air and quickly jumps to another as he continouesly dodge the attacks that were directed at him, but when the moment he decided to step and dashed towards kaido, he suddenly could see the latter's smirk as he stretched out his hand and black flames assualted him on his front
With another mayhem a streak of black flame more hotter than blue flames melted one section of the castle interior thus causing a large hole to appear at it's side
Unfortunately Asuto was unharmed as he somehow was able to twist his body to forcefully turn it's direction to the ground and dodge the attack by a hair's breath
But that didn't assured his safety as Fengris came in with his claws outstretched and fur started to appear on its skin
"20% release"
As Fengris was releasing his 20% he became much faster than he originally was as his traits of a black Fenrir became more prominent than his human form that was only using 10% of his original strength
But that didn't made Asuto falter as he quickly stood up and returned a slash aiming towards Fengris chest
At that moment all hairs from Fengris suddenly stood as he released even more of his black aura that forcefully pushed Asuto away and blocked his attack
"25%"
Once more fangs appeared on Fengris mouth as his aura once again shot up to another level
With a tap Fengris dashed forward as he came before Asuto and started raining down attacks towards him, of course Asuto returned his every punch with a sword attack from him
"30%"
Once again Fengris aura shot up to another level as his Fenrir's ears sprung out of his head
With his pupil constricting to straight beastlike eyes Fengris then started using magic to gift against the fake knight
"Claw strike!!!"
With a wave like aura rushing towards Asuto in a form of a claw, the Dark Knight himself suddenly formed a barrier around himself to directly block against the attack
With a loud explosion Asuto successfully blocks Fengris attack with his aura shield and started to look up when suddenly a palm took a grab of his head and Fengris slowly muttered near his ear
"40%"
With his aura becoming more stronger than ever a Fenrir's tail suddenly sprung out behind him, with a thought Fengris slammed Asuto's head on the wall before delivering a straight punch to the guts which boomed out like a sound of a cannon firing due to its power being generated from the attack
At that moment however Asuto stood there unscathed as his armor successfully blocks the majority of Fengris attack and neutralized bits force with a shock absorption of his armor
This of course causes Kaido to be amazed by the armor itself, but this kind of failure to give a damage angered Fengris even more so
With a step from Asuto he made a dash aiming for Kaido once more but this time Fengris swept his claws over pushed back Asuto with his own force and with a jump he came crashing down towards Asuto which causes a huge interior damage to the castle and shook it
With a punch so strong he once again attack Asuto with all of his might at his current level of strength, of course Asuto once again defended successfully from those attack, he even successfully came pass through Fengris defenses and managed to cut off some of its hair
With that both Asuto and Fengris rapidly delivered blows after blows against beach other until the former started pressuring the latter causing the momentum in power to shift to the other side slowly
Left with no choice Fengris muttered
"50%"
With that Fengris look became more prominent as a Fenrir as his hands and feet completely turned into Fenrir's claws and legs which made him really look like a half breed in this form
With this level he once again started pressuring Asuto with his attack that seemed to break the void due to it's speed
But at that moment Asuto's expression became stern as he punched Fengris to the face and kicked him away, but such attack was already useless and this in turn causes Asuto to smile for the first time
With a moment the fight based on strength suddenly became a battle of speed as Asuto disappeared infront of Fengris and appeared behind him like a blink to deliver a slash
But just like what he did Fengris also disappeared and appeared behind him and attacked from behind
With that their fight became even wilder as no sides wants to back down against the other
Of course due to their elevated battle the wide castle interior wasn't Enough for them to show out their extreme as they crashed repeatedly against the walls to try to outdo the other
At this sight even Argos and Aileene became serious as they finally face an enemy that has actually forced Fengris to use half of his original strength just to fight against it
With each collision shockwaves pour out from them as the castle continued to shake with their attacks
Even the simple personnel inside the castle was panicking due to it's shaking, bit that didn't stop them from clashing against each other with each other as they deliver blows after blows of attacks non-stop
With a sudden aura blast from Asuto and a overpowering punch from Fengris the castle couldn't hold it any longer as they suddenly got blasted out and crashed against the hard pavement on the front of the castle where the bodies of the dead Demon's litter
These corpses however were the demons that tried to attack them when they were going inside the castle
As both aura clashes both Asuto and Fengris suddenly shot out towards the different direction as they crashed to the ground
When they stood up however both Argos and Aileene who just got down from above together with kaido, were surprised to find out that there were only few scratches on the black knights armor
As for Fengris even thought there wasn't an injury, he seemed a bit tired which is apparent due to his heavy breathing
"Hahahaha! That armor is really something, not even my claws could barely scratch it... You got some interesting armor there" praised Fengris as he placed his hand over his waist and breaths out
Of course Kaido agreed to Fengris assessment as he too was observing the Black Knight that just kept surprising the four of them cause of it's strength, with that he became even more curious of its identity
As for Asuto he finally exhaled as he too spoke up
"And the Calamity Class Beings never ceases to disappoint me, your strength really does are worthy for their stories of world enders, no wonder gods are afraid of such power that could possibly harm them"
Hearing that Fengris also agreed to his assessment as he became even more wary of him
With that Asuto charged in once more as he clenched his sword and came it with a huge aura attack
"Sword descent!!!"
Seeing that gigantic attack from Asuto, Fengris pupils once again constricted to a blade shape as he started to growl as Fengris deeply breath in
"Fenrir's howl!!!"
In retaliation Fengris activated one of the Fenrir's deadliest attack which causes destruction everywhere when used
With the howl vibrating through the air the aura sword eventually broke apart as it continued to shake the land due to its force
With such attack the castle started to have cracks appear on it's walls as it blasted out and destroying everything, the ground was uplifted, the sky turned dark, arcs of black lightning struck the ground, air waves were vibrating, and the walls were exploding
Due to such attack Asuto was completely suppressed as he got blasted away and started to bleed from it's ears, thus marking as his very first major injury
After that attack the castle was already indistinguishable due to it's form that looked like an abandoned old castle that was ravaged by war
Luckily both Aileene and Argos managed to put up a magic and sound barrier to block Fengris indifferent attack and kept the safe
Of course due to that Asuto started to stand up and strike again when suddenly a magic circle appeared before them and thick smoke suddenly came rushing in covering Ng the whole area with fog that neither senses nor magic could detect anything
"What the!?!?" Reacted Kaido as soon as he a saw magic circle appearing beneath him, Aileene, Argos, and Fengris
But before he could react another one, all four of yh suddenly got teleported elsewhere which silenced the place as the fog started disappearing
When Asuto came to be he soon realized that the four of them went missing which made him even more wary than before but after thinking for awhile he suddy realized that someone intruded their fight
With a click of his tongue he decided to search for the person responsible to that interference
With a step he disappeared which left the whole place completely silent
