Mavislin nearly yelled her lungs out as felt Bryan's power nearly extinguish. Benjamin was still holding onto her as she panicked.
"So, the battle has taken a turn for the worse. Will you take my power to help your Slayer?" asked Benjamin, looking into Mavislin's eyes.
The young girl was still hesitant but began to see that offer as favorable. Benjamin smiled as the Valkyrie began to accept her twin's power.
Before Ysabeau could deliver the finishing blow, a shine of light zipped right between the two fighters. Bryan was dazed and confused as he saw the Valkyrie holding onto him, bridal style.
"Thank you for holding out this long. I'm sorry that I couldn't wake sooner," whispered Mavislin, her fringe covering her eyes.
"No problem. But my body hurts. Can I rest?" asked Bryan, visibly drained.
Mavislin nodded as she laid him down. She then stood tall and summoned her shield once more.
"I told you not to touch him, High Queen Meslander," bellowed Mavislin as her hands clawed onto her shield.
"You've already expanded most of your power, what else can you do? You can never get the higher ground from me, Valkyrie," said Ysabeau.
"No, I will never do so."
Ysabeau smiled as she wanted to claim victory.
"Not with this Element, at least," murmured Mavislin as she did something that shocked the people around her.
Ysabeau was soon met with a flying shield. This surprised the Bahamut as she barely enough time to react when she was hit, head-on by the giant weapon. Lord Atlantia weighed a tonne when in its physical.
The attack used nothing but the Valkyrie's sheer physical strength, which was on par with an adult Bahamut. Mavislin, in a sheer attempt to counter Ysabeau's attack, threw her entire sword and shield. It was also an attempt fueled with fury.
The same shield that Ysabeau and the others had forged was now being handled like a frisbee. This also braved the power of Tiamat and the Corrupted One and now Ysabeau's neck was at the mercy of it as she flew through the forest.
By tossing the shield, the impact of the throw sent Ysabeau flying towards the arena where Z and Raiyen were busy fightings. They had the shock of their lives when a flying Ysabeau crossed their paths. Mavislin, not wasting the opportunity, jumped from her spot to follow her shield.
"Let the water flow and turn into Light within the emblem in my hands. Let this emblem get tainted and turn this Light into Darkness within all. Divine punishment descends from the heavens," chanted Mavislin.
Raiyen's eyes widened as he recalled a familiar-sounding incantation. It was very similar to Monody's incantation. That meant she was going to summon a spell of the highest caliber. The Major Spells of Valokia...
No, wait, she was creating a spell. The Alter versions were never written down, the main reason why Raiyen couldn't use them without having to deplete half of his Energy pool. That would mean she was making up a spell right there and then.
The same as what she had done before. Now, it was time to see if she would fall after this. The last time used that, the battle ended quickly. By using the Conversion of Elements, it gave off signals that Mavislin wanted to end the fight with a bang.
"Sapphire Slash!" yelled Ysabeau, frantically trying to stop Mavislin's shield.
It bore no use as the Valkyrie's power absorbed it in an instant. Mavislin's eyes held no expression as she continued the last part of the incantation. This scared Ysabeau, knowing that something was very wrong.
"Overturn this spell for this land to strive and flourish once again..."
Gripping her shield once more, Mavislin called out the words that would change the tide of the current battle. Ysabeau had no time to dodge as she witnessed the shield morph into something that would haunt her memory forever.
Souls of those who were once humans cried and wailed as the heads of the fallen appeared on the shield. Bones and skulls adorned the rip of the once majestic shield.
"Heaven's Wheel Alter: Black Ocean," called out Mavislin as Lord Atlantic became fully black.
The Valkyrie's Aura changed from gold to black in an instant as Ysabeau tried desperately to fling Mavislin away. But the worst was yet to come as streams of black water started to corrupt Ysabeau's wings.
"Sapphire Cascada!" yelled Ysabeau, in a futile attempt to push back the converting Valkyrie.
Her eyes widened as Ysabeau witnessed her own spell get converted into a black mess with her very eyes. The spell did no damage to the Valkyrie whatsoever as Mavislin merely dispersed it into thin air. She then stood there, rooted to the ground, in shock and terror.
