"Wind Magic:Tornado Fang!!!!"

With his grimoire opened, Yuno creates a large, horizontal tornado that drills its way towards the devil. Seeing this, the devil smiled as he could easily counter this spell.

"Wall of Fire!!!!!!!"

As the devil said this, a wall completely made of flames appeared in front of him as he used it to defend himself from Yuno's spell. While this happened, Asta charged through the wall of fire with his anti-magic sword as he tried to impale the devil, but it quickly flew to the left to dodge.

"Ice-Make:Death Scythe!!!!!!!"

Kyoya first creates a large scythe made out of ice, and then jumps into the air. When he's high enough, he swung the scythe at the devil. As he did this, he cuts off the devil's right arm and then kicked him into the wall.

"Heal!"

As soon as the devil uttered that word, it managed to regenerate its right arm. While this happened, the devil looked at the ice mage in rage. Soon the pages in his grimoire began to turn as he faced the group of mages in front of him.

"Die.......you wretched insects!!!!!!!!! I'm going to exterminate every single one of you!!!!!!"

As the devil said this, multiple demonic creatures began to manifest from the devil's magic. The monsters all began to launch themselves towards the group of mages. While this happened, Kyoya quickly used his Devil Slayer Magic to freeze some of the monsters solid.

"Asta, Yuno. You two are amazing. To be honest, I always felt like a failure of a magic knight compared to you two. But I couldn't ask for better allies now. That's why I have one request for you both. Let's surpass our limits and shut this bastard up for good."

"..........Yes sir!!!!!!!"

Asta and Yuno flew upwards as they were heading towards the devil. While Asta manage to slice through some of the creatures, Yuno blocked their attacks with his own blade. While this happened, Kyoya was concentrating his mana.

"I haven't had this magic for long, so I might be sloppy with it compared to dad. But......if I use the ice from this magic and use what I know from training with Ur and the experiences leading to this moment......I can fight with this magic in a way only I can do!!!!!"

While Kyoya was concentrating on his magic, several monsters were heading towards his body. When this happened, Patri quickly flew behind the ice mage and blasted the monsters with his light magic to protect him.

As the devil saw Yuno and Asta approaching him, he saw Asta slicing up the monsters as his anti-magic was being drawn in by Yuno's magic as they approached him. However, as soon as another monster was sliced he only saw Yuno heading towards him.

"Not yet......i'm not done yet!!!!!!"

From behind the devil, Asta emerged from the severed monster remains that he hid behind after slicing it. Asta was being pulled in by Yuno's magic while holding his anti-magic sword, meanwhile, Yuno was charging towards the devil from an opposite direction. Both of their blades pierced through the devil's flesh. However the devil killed the momentum by saying one thing.

"Stop."

Yuno and Asta's speed was reduced by the command. As the devil grabbed a hold of Asta, the boy reverted from his dark form as Yuno was being pushed away by the devil. But while this happened, Kyoya was giving off high amounts of magic power as he looked at the devil.

"This mana......I can tell he's got the same idea as I do. Well then, let's give this devil hell, Captain Yami!"

~With Yami~

Charla held back Yami's katana with her briars to give his next attack more momentum as the man held it over his head. While he was concentrating, the cigarette that Yami had in his mouth was falling to the ground as he said one thing.

"Let's do this Kyoya. Mana Zone:Dark Magic:Dark Cloaked Dimension Slash:Equinox!"

After taking control of the mana in the area, Yami performed his Dark Cloaked Dimension Slash while greatly extending the range and reach of his slash. Meanwhile, everyone in the top floor of the Shadow Palace saw the devil suddenly get sliced down the middle along with several monsters. As the devil was struck by the attack, vomit began to escape its multiple mouths.

"Dammit!!!! Dark Magic can interfere with the other world. That damn swordsman!!!!!!!"

"You pieces of trash!!!!!"

As the devil said this, spikes made from its own flesh were launched at Yuno and Asta, who were trapped in his clutches. As Yuno held his sword next to him, he thrusts the blade as a tornado formed and blew away the projectiles along with the devil. While this happened, Nero flew towards Asta to help him recover.

"Sealing Recovery Magic:Heavenly Prison:Faint Omen!"

With her grimoire opened, Nero places her hands on Asta and temporarily seals away his bodily damage. Seeing this, Asta began to coat his body in anti-magic as he flew towards the devil. He held his sword tightly as he swung it down onto the devil's neck.

"Stop. Stop. Stop. Stop. Stop."

As the devil used his magic, Asta felt his speed slowing down a bit. As his sword cut into the devil's flesh, Asta was having trouble getting his blade to cut through the devil. But Asta smiled when he remembered someone else was involved in this fight. Soon he began to remember times that the individual gave him support during some tough battles.

"That was my all.....so I leave it up to you. Finish this.......ASTA!!!!!"

"Win so that I can see you become the Wizard King! I'm counting on you Asta!"

"When things get tough, he's always relied on me and had faith in me. Now it's my turn. I may be at my limit.....but I know he can defeat you. I'm counting on you.....KYOYA!!!!!!"

As Asta shouted this, the boy in question smirked as black marks were also appearing on the right side of his body. He was gathering mana and concentrating on his Devil Slayer Magic for this one moment. Soon Kyoya ready to attack as he saw Asta fly away from the devil.

"Thank you, Asta. Ice Devil's Zeroth Destruction Bow!!!!!"

While the devil was distracted with Asta, Kyoya created an intricate bow made of ice and charges it with an ice arrow that he fired at the creature in high speeds. Once the arrow pierced the devil's heart, it turned into a spiky array of ice that tore apart the devil's flesh from the inside. As the devil looked at Kyoya, he realized something. He lost to a mere human.

"That human......is a monster."
