~In the Clover Kingdom~
"Let's invade the Spade Kingdom!!!!!"

"I know I said that, but it will take a while to get there from the Clover Kingdom, even with Devil Union."

As Asta said this he saw Gimodelo, the devil that Nacht left behind to supervise him, on his shoulder as he spoke up. He mentioned that long distance teleportation was impossible without Nacht and that he was not in a state where he could do it.

"Then how-"

Before he could finish his sentence, Asta's Devil Union form wore off as he was now falling towards the ground. However, when he opened his eyes, he felt himself land on something soft. As Asta looked ahead, a smile appeared on his face.

~In the Spade Kingdom~

God Serena laughed at the display. While Mereoleona left during their battle, he at least had something to enjoy. Watching weaklings struggle to fight something that they have no chance at defeating.

"Well then, I better get back to work and give the devils a hand. Now then, who to go after fi-"

"Ice-Make:Ice Volcano!!!!!!"

With his grimoire opened, Kyoya slaps his hands onto the ground and causes a miniature eruption below God Serena. The ground below God Serena is rent apart into the shape of a crater, while large chunks of ice are rapidly and erratically spewed out of the pit, devastating the immediate surroundings. As God Serena was bombarded with ice, he saw a single mage walking towards him.

"What the hell? You're Silver Fullbuster's son?!"

"Silver was the former king's brother and royal guard. Is his son here to take the throne back? No, he's nothing more than Vanica's toy?"

"I won't lose to the likes of you, boy!!!! Cavern Dragon's Earth Collapse!!!!!!"

God Serena slaps his hands upon the ground and destroys the earth in a relatively large, explosive radius, which not only destroys Kyoya's footing, but also bombarded him with extremely large boulders that were fractured from the ground.

"I knew it. You're not even close to being as terrifying as Natsu or Uncle Reaper!!!!!"

Kyoya created multiple platforms of ice to maintain his footing. Just as he was above God Serena, a smirk appeared on his face as he knew that he had enough momentum for his next attack.

"Take this!!!! Ice-Make:Cold Excalibur!!!!"

With his grimoire opened, Kyoya created a longsword out of ice and swung the blade at God Serena. Seeing this, God Serena caught the blade between both of his hands but his eyes were widen with shock when he saw his own body being frozen in ice. Soon God Serena's body was completely encased in ice. Afterwards, Kyoya punched God Serena's face, causing the ice to shatter as the man was sent flying backwards.

"Now's my chance!"

"Ice-Make:Hamm-"

"Sea King Dragon's Encircling Deluge!!!!!!"

God Serena gathers a wave mass of water and released it as a spiraling torrent from the palm of his hand. As the torrent was rushing towards Kyoya, the boy knew he couldn't afford to make a mistake.

"It's been a while since I used this. Ice-Make:Ocean!!!!!"

After joining both hands together, Kyoya slammed them onto the large body of water and froze it in a matter of seconds. God Serena was in shock. How could a boy this young have so much strength? It just didn't make any sense. How is he this strong and he doesn't even posses a devil himself?

"Who the hell are you?"

"I'm a lot things. I'm a weakling in some people's eyes. To some, i'm just their plaything that they cursed.....but....."

Soon Kyoya began to think about his time in the Clover Kingdom. The time he spent with Juvia. The fights he had with Mukuro. The day he found Ultear. But most importantly...he remembered how he spent time with his fellow magic knight squad mates. Soon a smile appeared on Kyoya's face as he clenched his fist.

"...i'm a member of the best magic knight squad!!!!!!! I'm a member of the Black Bulls, Kyoya Fullbuster. That's why.....i'm taking my captain back with us, you son of a bitch!!!!!"

As Kyoya said this, he punched God Serena in his gut as hard as he could. The man coughed up blood as he was sent flying and landed harshly onto the ground. When he looked up, he saw Kyoya dashing towards him.

"Ice-Make:Rose Garden!!!!!!!!!"

With his grimoire opened, Kyoya releases chunks of ice in the form of roses and thorns towards God Serena. As God Serena was being attacked by the thorns of ice, he saw that a part of his body was frozen, rendering him immobile.

"Ice-Make:Ice Impact!!!!!!!"

Kyoya creates an intricately-designed hammer made of ice, which he brought down onto God Serena, creating a giant impact. As the hammer disappeared, Kyoya saw God Serena on the ground as he was getting back up.

"Hehehehe. Hahahahahahahahaha!!!!"

"What's so funny?!"

"Foolish boy, your attention was so focused on me........did you forget about the several devils that are here now that the gates of the underworld have opened!!!!!"

As Kyoya turned around, he saw the army of devils rushing towards Benimaru, Xanxus, and the Spade Kingdom resistance. He knew that Benimaru and Xanxus were low on magic power, yet a smile appeared on his face as he looked at God Serena.

"I'm not worried about them. They've been in tougher situations than this. Besides.....they're in good hands."

~Meanwhile~
"These things are annoying!!!!"

The army of devils charged forward as Benimaru and Xanxus were standing side by side, while Mereoleona was already facing off against half of the devil army.

"Let's go!!!!!"

"Right!!!!!"

Benimaru lunged forarwd as he covers his right hand in flames. Just as a devil was right in front of him, he drove his right hand into the devil's right eye and burned it's body from the inside. As the devil's body was now a burned corpse, Benimaru quickly stepped to the side as Xanxus fire multiple bullets of flame magic from his guns towards a small group of devils that were heading for Benimaru.

However, just as Benimaru dodged, he saw a horde of devils heading straight for him. He knew he couldn't do nothing, so he was trying to find a way to counter the devils. However, before he could muster a single flame, a huge blast of magical power vaporized the horde of devils as he was also engulfed in the attack. When this happened, Benimaru turned around and saw runes on his back.

"That was some powerful magic. Despite being caught in the attack, I didn't feel anything. It was the devils who took the attack. But who casted that spell."

As Benimaru turned around, his eyes were in shock with what he saw. Soon a small smile appeared on his face as he said one thing when he saw the people who helped him out.

"Trying to look cool huh. You guys are some flashy reinforcements!!!!"

"We won't let the devils spoil this world!!!!"

~With Kyoya~
"More of you insects are crawling onto the battlefield?!"

"Hahahaha. This is why i'm not worried. Because those idiots got my back no matter what. Though if anyone should be worried, it's you."

As Kyoya said this, God Serena felt a tremendous amount of heat radiating from the boy's body. While this happened, Kyoya was slowly removing the bandages on his left arm. God Serena knew that Kyoya was up to something and he wasn't going to sit by and watch it happen.

"Purgatory Dragon's Blazing Inferno!!!!!"

God Serena engulfs his fist in infernal burning flames and then, by moving his fist forward, releases the infernal fire which explodes, becoming a colossal sphere of flames incinerating the area Kyoya was standing in.

"See. No matter how you look at it, i'm the strongest here. Stronger than you, stronger than that woman, stronger than your pathetic captain!!!! Stronger than E.N.D. himself!!!!!"

"Stop talking out of your ass."

As God Serena heard this, he looked towards the sphere of flames. When he did, he saw something escape the sphere. Upon closer inspection he saw that it was bandages. Suddenly, God Serena felt an enormous surge of mana in the area. As he looked at the sphere, he saw that Kyoya was eating all of the flames.

"Impossible! His element is ice yet he's devouring the flames?! Don't tell me...is he also....."

"Those flames taste awful. Even Noelle's cooking is better and the crap she makes isn't even edible sometimes."

As soon as Kyoya was done eating the flames, he glared at God Serena. He was fine with being called weak, he got use to it over time. But the moment he disrespected Yami and Natsu, Kyoya knew that God Serena just buried his own grave. Soon an eruption of flames escaped from Kyoya's body. While this happened, the mark on his left arm started to glow.

"What is this power?!"

"This...is the gift given to me by a dear friend. Show him respect. His name isn't E.N.D, his name is Natsu Dragneel! By the way, my captain is Yami Sukehiro!!!! And i'm the guy who'll send you to hell, Kyoya Fullbuster!!!!"

As a result of the sheer potency of the ability itself, before even properly utilizing the power to its fullest, Kyoya was radiating incredible heat earlier. Now that he's using the gift that Natsu gave him without the bandages that Nacht gave him to suppress the magic, Kyoya was unleashing the magic all at once.

Soon the ground itself becomes lit in a circular crimson inferno; the snow around Kyoya instantly melted and quickly evaporated, leaving nothing behind. As Kyoya glared at God Serena, he said only one thing in a calm, ominous voice.

"Fire Dragon King Mode."
