"Ice Devil's Shiver!!!!!!!"
Kyoya creates an ice shard funnel that forms a straight line towards the etherious. Seeing this, the flames the etherious was emitting were burning brighter.
"Fire Dragon's Sword Horn !!!!!!"
E.N.D engulfs himself in flames as he and propels himself towards Kyoya's spell. When he made contact, the ice shattered but he lost sight of the devil slayer.
"Ice Devil's Zeroth Destruction Fist!!!!!!"
After producing the same type of ice that he devoured from Invel, Kyoya creates a pair of destructively powerful gauntlets with same properties as the aforementioned ice and launches a flurry of powerful punches at E.N.D as the etherious' body was being frozen down to the bone.
Soon the etherious grabs Kyoya's arm as his flames were burning the ice mage. Seeing this, Kyoya kicks E.N.D in his chest as he jumped back to gain some distance. Both of the fighters were breathing heavily, they were starting to get exhausted.
Soon the two of them stood back up. No one moved as silence filled the air. As they slowly lifted their heads, their gazes were fixed on each other. Their focus was unwavering in this moment.
"Ice Make:Ice Geyser!!!!"
Freezing the ground in front of him, Kyoya creates a tower of ice spikes that impales the etherious. As E.N.D coughs up blood, he engulfs his body in flames as he melts the ice. However, when he did, he lost sight of the ice mage.
"I'll use all of my strength...to destroy you."
Kyoya created a large axe sword from his Ice Devil Slayer Magic as he held it in his left hand. Soon E.N.D sensed Kyoya's mana and he swipes his arms through the air as the flames from them were heading towards Kyoya.
As the flames made contact with Kyoya, the ice mage saw the etherious rushing towards him. As he endured the pain of the flames, he saw E.N.D preparing to attack him again. That one second, that brief opening that E.N.D has.....Kyoya is going to use this moment to his advantage.
"Ice Make:Nine Lives.........BLADE WORKS!!!!!!!!"
After crafting the giant axe sword made from his Devil Slayer Magic, Kyoya strikes E.N.D at his upper arm, collarbone, windpipe, temple, diaphragm, rib, thighs, and his chest simultaneously at incredible speed. Before E.N.D realized it, he was on the ground in a pool of his own blood.
However, E.N.D was getting back up. When he did he charged at Kyoya with immense speed. Soon the ice mage used the axe sword he made to defend himself from E.N.D's kick. However, the etherious swiftly spun its body as it kicked Kyoya's head and sent him flying through several trees.
"Ice Make:Ice Impact!!!!!!!"
Kyoya creates an intricately-designed hammer made of ice, which he brought down onto the etherious, creating a giant impact. As E.N.D broke the ice, he felt a pain in his head as he heard a conversation. One that seemed too familiar.
"When we get out...I promise.....i'll get strong enough to beat Vanica and save you!!!!!!"
"Natsu.....thank you."
Soon Kyoya and E.N.D lunged forward. As Kyoya punched the etherious in his chest, E.N.D sweeps Kyoya by his leg and slams him into the ground. Afterwards, he stomped on the devil slayer as his rage seemed endless.
"I'll kill you Vanica!!!!!! Fire Dragon King's Hellfire!!!!!!!"
After charging his foot, releasing a great amount of flames in the process, E.N.D envelopes Kyoya in flames that took on the form of a devil's head that consumed the ice mage. The forest they were in was now just a sea of flames. As the flames covered his being, Kyoya was struggling to keep up his mana skin. He had to do something, or else he'll be doomed.
Soon Kyoya opened his mouth as he starts inhaling the flames. As he consumes the flames, he felt as if his insides were melting. While this was happening, E.N.D was thinking to himself.
"Kyoya........I leave half of my magic to you. This is all I can do for you now......please.......stop me....."
Soon Kyoya devoured most of the flames. However, he began to feel ill after consuming them as his left arm felt like it was burning. As E.N.D. charged towards Kyoya, the ice mage was about to use every last drop of his mana to end this fight.
"Ice Make:Silver!!!!!!!!!!!!!"
Using his Devil Slayer Magic to boost his Ice Make Magic, Kyoya gestures with his right hand and froze E.N.D along with the area around him in an instant. As this happened, the ice that captured E.N.D shattered as he was walking towards Kyoya.
As this happened, Kyoya was approaching the etherious. However, he saw that the veil of flames that covered E.N.D was slowly fading away. When this happened, the etherious smiled as it struggled to speak.
"Kyoya......thank god....you're alive.....those flames you consumed.....you'll need it. That is the only gift I can give you....for now. Please.........if we meet again.....I want you....to kill me."
As Kyoya listened, his rage was slowly fading along with the black markings on his body. Both him and the etherious were slowly falling onto the ground, as they were both losing consciousness Kyoya saw the face of the devil. As he reached out his hand towards him, he muttered one thing before being knocked out.
"....Natsu......."
As the two fighters were now unconscious on the ground, a new figured entered the battlefield. With a bored look on his face, he appeared next to Natsu. Soon he sighed as he picks up the etherious.
"Honestly, Vanica needs to take better care of her pets. I already took out those weaklings known as the Golden Dawn and captured William Vangeance. Why do I have to do everything?"
As Zenon took E.N.D and left to go find Dante, he thought about the state of the battlefield between E.N.D and his opponent. Whoever he was fighting must have been a real monster. Soon Zenon spoke to himself.
"I wonder what part E.N.D's opponent has to play."
~With Kyoya~
The ice mage was lying on the ground as he lost consciousness, however, something wasn't right. On his left arm, instead of ice, flames began to manifest as it burned intensely. Soon the flames began to die down as a single mark was seen on Kyoya's arm.
As the dragon-like mark was on Kyoya's left arm, an enormous amount of mana could be felt from it. Soon an individual walked towards the ice mage as he held several bandages. Soon the mage wrapped the bandages around Kyoya's left arm as the intense mana was being sealed by them.
"It seems as though that etherious has gifted you with a small portion of his magic. Was it luck or was it fate that you managed to be compatible with it despite being an ice mage?"
As the individual said this, he took a quick look at Kyoya's grimoire and was surprised by what he saw. While most of the boy's spells were ice based , there were now some spells that were fire based. Soon a chuckle escaped from his lips as he also sensed a presence inside it.
"Well then....it seems like you're a wild card for what's to come, my junior Black Bull member."
