"Come! Show me how far a human can go!"
My father's blades quickly impacted Berith's Pike, as he suddenly noticed that the Pike itself couldn't bend so easily. And the worst part, the countless bones and heads stuck to the spear began to move by themselves, like an army of wailing undead trying to catch my father.
"What the…?!" My father asked in surprise, quickly parrying several attacks from Berith's Pike while trying to survive.
"What's wrong? Are you surprised?" Berith asked. "This Pike is not something you can easily destroy! It has been Cursed by trillions of souls sacrificed over the eons I've been wandering across many worlds with my Lady Lilith. Even your "Dimensional Cut" might not do the trick now!"
My father, however, suddenly remained calm, as he began to somehow analyze the situation. The flames erupting from his body suddenly changed, becoming calm and beautiful, with white and blue colors. His armor changed as well and he gained long Phoenix Wings.
"Phoenix Full Synchronization."
His two swords unified, forming into a long and thin blade. I had never seen a sword before, but from what I got by analyzing it with Alice's System abilities, it was simply called "Katana".
"A thin blade? What will that do?" Wondered Berith with intrigue. "Well, no matter. I am tired of waiting, I'll go myself!"
His horse moved at a super sonic speed, reaching my father in a matter of splits of a second. His entire Pike was imbued with gross amounts of Demonic Energy, as it was directed towards my father.
The Pike pierced through my father, as I felt my heartbeat faster.
However, instead of being pierced, it felt as if… my father turned himself into fire, the attack easily pierced through him because he was flames themselves.
"Oh?! Elemental Transformation at such a high level!" Berith praised my father.
"I cannot fight you with brute force, but this should do for now… Blazing Katana Arts: Thousand Swallows."
Suddenly Berith's entire body looked like it was being sliced by countless swords at the same time, piercing through all of his armor, beheading his horse, and quickly shrouding him with countless slicing wounds.
SLASH! SLASH! SLASH! SLASH! SLAAASH!
His entire armor exploded into tiny pieces, as his horse quickly exploded into blood and guts, dying on the spot. Berith remained near naked in the sky, covered by wounds as my father remained in silence in front of him, sheathing his katana once more, as if the effect of the attack had yet to end until then.
And then, an even stronger slashing attack hit Berith's chest, piercing through his flesh and making him bleed an entire fountain of demon blood.
Berith couldn't help but groan in agony, vomiting a mouthful of blood and looking at my father. His actual body resembled a blue-skinned demon with countless scars over his body. My father ended opening most of such scars. His face had red eyes and was completely bald, with long horns that spiraled high.
"Impressive…" He muttered in surprise, smiling monstrously. "This might be one of the greatest challenges so far!"
My father quickly held his katana's handle once more, as Berith's blood suddenly began to evaporate into red essence, as if it were turning into Demonic Energy…
"Demonic Sacrifice…!"
Berith's entire body suddenly was reinforced, black tattoos grew over his body resembling flames, and his muscles grew up to three times their original size! Not only that, but his menacing presence was multiplied several times. He resembled a titan!
"By sacrificing your own blood you can enhance your physical strength that much…" Said my father, looking at Berith switching his fighting style as his Pike grew more robust, as if it were made of flesh and bones.
"That was merely the appetizer!" Berith laughed.
My father and Berith once more clashed against one another with their weapons, enormous shockwaves were unleashed all across the skies one after the other…
It was complete insanity. I couldn't do a single thing right now. I was just there, standing, and without even being able to do a single thing. These fights themselves were way above my own scope, in another dimension entirely…
And they were not over. Lilith and Astaroth immediately decided to act themselves as they left my father being distracted by Berith. I saw Aquarina and Zack making the same faces I was making, all while enormous Red Demons slowly made their way towards us, their very presences combined together forming a big aura of Miasma that seeped into the ground.
"R-Red Demons… We were barely able to fight one before! How are we going to defeat so many now?!" My mother asked.
"T-This is too much…" Aquarina said. "And where is mama and papa? Are they okay?"
"Don't worry, I can sense that they're still alive, they're moving around. Most likely trying to destroy this entire Domain. If this Domain is destroyed the demons themselves should weaken severely. But for now… Sylphy, can you give me some of your strength?" Asked my mother.
"Oi! Don't forget about me…! You've been just ignoring me just now." Agni, the prideful big brother of Ignatius spoke.
"Ah…!" I quickly realized he wanted a contract. Maybe if I can get his help, we could pull through this?
"A contract?" I asked. "Well, sure! Why not?"
"Wait!" My mother quickly interrupted us.
"What is it!?" Agni furiously replied.
"Sylphy's soul is not big enough to make a contract with a monster as big as you! Familiar Contracts can only be made when both souls are at least within similar wavelengths. Sylphy's soul has yet to even reach such a state." My mother said. "If you forcefully make a contract with her, you'll end up hurting her soul."
"What? That's a thing?" I asked with disappointment.
However, Alice seemed to have an idea to make this possible.
