Nereid Kyrie.
This was the Sacred Gear that was owned by Ingvild, which gave her two distinct abilities, one of which is the power to manipulate Dragons by using their singing voice and manipulating the sea.
With those two abilities, it could be said that this Sacred Gear was on the same level as the Longinus, which was the strongest type of Sacred Gear. As she combined her power, which she inherited from her heritage, the Leviathan, which was known as the Sea Serpent of the End, she became an unstoppable force, and if she wished to, she could destroy the world by sinking it into the water.
Yes, with the combination of her Sacred Gear and her innate ability, she could create an ocean with ease, especially when her Demonic Power was at the Satan-Class.
"NOOOOOO!!!"
"HELP US!"
"I DON'T WANT TO DIE!"
At this moment, all the opponents were drowned by Ingvild's water as she didn't want to waste any more time, and she also had to be serious to face Walburga.
Yes, Walburga was the only opponent that Ingvild had to watch out for, as Shalba and Creuserey were taken care of by Michael and Baraqiel, so she could focus on this vicious magician.
Walburga might not have a beautiful face, and her appearance was just so-so, but even so, her talent as a magician was one of the tops, and more importantly, she also had a Longinus similar to those from the Hero Faction!
As for why her status was higher in the eyes of the Old Satan Faction than those of the Hero Faction, it was because she was a magician, and the devil had always made a contract with magicians from the beginning, which made their relationship quite good.
Yet, Ingvild never thought much of Walburga's magic since no matter how strong her magic was, it was nothing in front of her water.
In front of her, she could make an ocean and create a gigantic tsunami that could swallow and sink everything. Walburga's magic was nothing!
"How scary~!"
Still, despite how strong Ingvild was, Walburga was calm as she teleported away with her magic from the tsunami, then stayed in midair, in a place where Ingvild couldn't reach her.
As a magician, flying magic was simply child's play for a genius like her, yet even so, where did her confidence come from?
"But Ingvild, no matter how powerful your Sacred Gear is, in the end, it is just a normal Sacred Gear!" Walburga looked down at Ingvild with disdain and mocked, "But mine is a Longinus!
"Incinerate Anthem!"
As Walburga shouted, a purple holy fire swept over the ocean and wanted to burn Ingvild to death!
Incinerate Anthem.
This is Walburga's Longinus, which is one of the Three Holy Relics, the Holy Cross on which Christ was crucified. Its special ability is to create purple holy flames in the form of a cross that can incinerate Devils with ease.
Naturally, while Ingvild was strong, she didn't dare to face this flame, and if she faced it directly, she would be burned to a cinder. Yes, she might be a descendant of the Leviathan, but even so, she was a devil, and she was weak against the holy attribute!
Controlling the sea, Ingvild quickly entered the ocean as she formed a dragon-shaped wave to meet Walburga's holy purple fire!
Sizzle!
The sizzling sound echoed as the water and fire met, yet watching Ingvild, who hid away, clearly running away, Walburga was so happy!
"Hahaha! Look, you can only run away like a coward!"
Walburga laughed arrogantly and continued her merciless attack.
"If you want to defeat me, then you have to do your best, Ingvild!"
Yes, while Ingvild might have an immense Demonic Power, Walburga also had quite a sum of magic power, and her Longinus was different from other Longinus that was dying and appeared like a tool that could only be used by sucking the energy from the user.
While Walburga's Longinus still consumed her energy, it didn't consume much, as it was like a living entity on its own, so the consumption of her magic was pretty low.
So, even if Ingvild continued to send torrents of water to her as she hid in the sea, Walburga wasn't afraid of a confrontation.
Yet as the fire met the water, the hot mist covered the battleground, which made it hard to see her surroundings, and made her quickly form a barrier as it was too hot!
Was this Ingvild's plan?
Walburga's expression became solemn, yet—
"Just kidding! Do you think that I don't realize your plan? I know that you must have prepared for this move, right?"
As expected, while Walburga's vision was obstructed by the mist, with her magic, she realized that Ingvild had prepared a gigantic tsunami wave that was about to swallow her!
Even if her fire was strong, facing this immense water, if she was unprepared, she would be defeated.
Yet, Walburga was prepared!
Even if Ingvild had sent her this sneak attack, Walburga was confident she would have met it head-on!
"Incinerate Antiphona Calvario!"
As she said those words, Walburga reached a Balance Breaker state and used her strongest move!
The purple holy flame formed an evil eight-headed dragon as it was crucified.
The size of this crucified evil eight-headed dragon was immense, as it easily reached 200 meters, then as the tsunami grew closer, it breathed out a blast of purple flame that would destroy everything!
"Hahahah! You've lost Ingvild!"
Yes, with this, Ingvild would be defeated!
Only—
"Huh?!"
As the fire met the water, instead of evaporating and turning into a mist, a strange, intense bubbling sound was heard, and Ingvild's voice was heard.
"Have you heard a steam explosion?"
"..." Walburga.
"When water is superheated by intense heat, it will react violently and create an explosion."
Chuckling, Ingvild said, "I know that you will fight me instead of running away, so thank you for meeting my expectations, and goodbye, loser."
"INGVILD!!!!!"
Yet, it was too late.
As Walburga was in deep hatred, she was also filled with endless despair, hoping for Masa to save her, thinking that her fate would be similar to Ingvild, who had become a queen right from a terrorist.
Unfortunately, her voice wasn't heard as the steam explosion swallowed her.
BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMMM!!!!
Inside the water, Ingvild looked at this scene calmly as she won her battle, then looked at Michael and Baraqiel, who fought Shalba and Creuserey, helping them so this battle could end as soon as possible.
Yet, while their battle was about to end, Masa's fight against the will of god was about to begin!
