Illayaka looked at her father and sister and slightly frowned. She felt that her sister was going to get too far ahead of her with the sudden power that she just gained. Up until the moment that she unlocked her Astrohollow manifestation, they were equal in every single aspect. Illayaka had more experience than her older sister, but now her sister was stronger than her.
…No…! I will not be left behind! I need to become stronger so I'm strong enough to fight beside my sister…
Mana rapidly flooded the area causing the universe to shake. The mana was coming directly from her body, and she was getting stronger by the passing second.
"...—!"
The two looked over at Illayaka, who was engulfed in mana. It was the same phenomenon that Illya went through when she was suddenly transforming into her new manifestation.
"Well, it looks like your sister is unlocking her new transformation… I'm going to wait for her to finish before we continue the fight."
Illya looked at her father before she looked over at her sister with a bright smile, "I'm going to wait for her with you. I want to see what kind of newfound power my little sister is going to have."
The mana that surrounded her body started to glow even brighter, and her outfit began to change. Her twin tails started to change into one ponytail, with two streaks of blue and people flowing through her hair. A magic formation that was like a halo formed over her head that was purple and blue. She had a beautiful cape that was reminiscent of the flames. But the flames were dark blue and purple matching her hair, and white knight-like armor.
Illayaka looked up at her father and smiled as the gun that was in her left hand started to transform into a long sword.
"Transform, Erial!"
Heeding her call, the gun had completely changed into a sword. The blade of the sword was the same color as her cape.
"Now that I have finally transformed… Let's get this battle started, papa."
Looking at his daughters, Shito jumped back, placing some distance between the three of them. They had already started to fight before so he had to reset the whole thing since they were standing beside each other… talking and waiting for Illayaka to transform.
Shito looked at his daughters, slightly smiling, "Are you ready to start this fight once again, Illayaka and Illya?" he asked, trying to make sure that his daughters were to start the fight once again.
"Yes, papa. We are ready to get this fight started…!" the twins shouted in unison. They had been waiting to test out their new powers and they knew that their father was the best person to train with, after all, he was the strongest person that they knew. And Illayaka knew more strong people from the realm of the void.
"Well, let the battle beg…—!"
Illayaka appeared in front of her father, swinging her sword in a downward motion. Space-time was physically cut through and what seemed left was a portal that was the same color as her cape.
"...Hmmm… that's interesting, you are physically cutting through space-time, creating a rift."
Illya smirked, "Well, don't forget about me, Papa!" she shouted, appearing behind her father, "Starlight Radiance."
Swinging her sword, Stars started to appear in the area. The stars were multiplying every single time she swung her sword. The power to physically create stars and use them to her will was an ability that she had. With the power of the void connected with her stars, she could destroy anything if she wanted it.
"...You are going to have to do better than that, Illayaka and Illya. We have been fighting for a little, you have a whole arsenal of strong attacks, and you haven't used a single one… are you two still holding back?"
"Big sister stay back; I'm going to try to use one of my attacks and I don't want you to get in the way. Even though we are supposed to be working together to fight him, I don't want you to get…—"
"No don't finish that sentence because we are going to do this together." Illya interrupted, "Let us try some combination attacks. This is going to be one of our first times doing this again."
Hearing those words, Illayaka smiled thrusting the palm of her hand forward, her hand was pointed at the portals that she created, and she smiled slightly as the portals started to glow brightly.
What appeared out of the portals was shocking, a shocking sight to see. Clones started to manifest and walked out of the portal. To the human eye, they looked like clones, but they were actually different versions of her that existed through different timelines.
Even if the clones were killed, it would not harm her in the slightest since she can't be killed even if they travel to the past or future and manage to kill her.
All the clones looked at their original body and smiled. "Why did you summon use her? Is there a reason you called to use her to fight." every single clone said in unison.
There were about ten clones in the area, so she was looking at herself and smiled. She had to give the clones a good reason for them being there. She summoned them away from their timelines so they could fight with her against their father.
Illayaka pointed at her father before smiling at the clones, "That's the reason I summoned you here. We must fight with our father for the day, so I need you all to help me."
"Fighting with father…!?" the ten clones said, looking over to the place where the original one was pointing. "There is no reason for you us to fight with Fath—"
Once their eyes fixed on their target, all of the chattering came to a sudden stop, as they looked at their father. They were already in their battle forms since they all transformed when they felt themselves being called to another world… they wanted to be prepared to kill the person on the other side before they decided to return to their world.
But that mindset shattered when they saw that the person, they were fighting with was their father. Each of the girls knew that he wasn't going to be killed by them because they were simply not on his level, but this gave them a reason to fight with their father for the day.
"Papaaaaaaaa!" the clones shouted in unison. They were happy to see their father again even though they had just left after seeing theirs.
Shito smiled slightly, waving his hands at his daughters. It was a beautiful sight to see his daughters having a good relationship with each other; after all, he was someone who loved being with his daughters and seeing them happy.
Illayaka looked at her sister and smiled. "Big sister, can you hold off Father, for a bit? We are going to combine one of our spells to make one big one," she said as she moved away, gathering beside all her clones.
Nodding her head, Illya tightly gripped her sword, and the stars in her eyes started to glow bright blue. Mana was surrounding her body, and a gentle yet strong aura appeared around her body.
"Estella!" Illya shouted fiercely. She dropped the sword that was in her hand, letting the sword fall slowly to the ground. "Multiply and become a blade that can cut through the heavens!"
With those words, the sword multiplied, floating around, and surrounding her whole body. There were about ten swords that were as powerful as her original one.
Grabbing one of the swords, she lifted the sword towards the heavens and smiled, "Well, since I have to keep you busy for a while, so, let's get this battle started once more."
A bright gold beam of light shot into the air. Her eyes glowed brighter and brighter, and the heavens were covered in a bright golden light. The heavens that stretched endlessly were covered in Illya's mana… mana that was strong enough to destroy and swallow worlds.
Let the heavens be engulfed in the light that shines brighter than the darkness. A light that shall pave a way through the darkness that one calls 'nothingness'...—!
The swords that were glowing brightly in her hand started to crack as her mana was getting stronger. By the passing second, her mana had already grown to the point where it could destroy multiple worlds if she decided to swing her sword.
"Twilight Radiance," Illya said, swinging her swords in a downward motion. The sword was completely shattered to pieces and faded from existence.
Multiple beams of light formed in the sky. The beams of light had the power to cause mass destruction throughout the entire world. A power that could erase people from existence and vaporize the gods and things that could be above that. This was a spell that was her own, something that she combined to make her own unique skills.
Beams of light fell from the heavens, aimed directly at her father. The beams could not kill him, but anyone else might be erased from existence.
Shito looked at the beams that were nearing his face and slightly lifted his hand, grabbing the beam of light.
"Now, this is interesting. A beam of light that could evaporate someone from existence, but that's only half of it. You can light your way through 'nothingness'... making your light shine and even conquer the never-ending darkness that we classify as nothingness." he said, crushing the beam of light that was in the palm of his hand. "Your existence is like a contradiction because half of your soul and body is made up of nothingness. Still, the other half holds the power to light up that very same nothingness. You are really the only person that is considered both non-existent and existent at the same time."
"H—, H-Huh…?" Illya was surprised by what her father was saying. She herself wasn't aware that her existence, to some extent, denied any kind of logic.
