Audrey almost unleashed her sealed magic from Draxus's fabricated world, but a painful sting occurred on her mind preventing her to do so. "Right... Strategy... One touch from that can kill me..." She muttered some words while Iapetus simply smiled. "We meet again, goddess of arcane magic. The Witch Elementalist of the Sentinels. How's your boyfriend's injury? I'll make sure to poke a hole in him again." He tried to aggravate her, which actually worked. However, Audrey already had control of her mind as Draxus has stapled the danger level of Iapetus since their rescue towards the second batch of [People from Earth]. Thus she knew what exactly to do. "[Souls Embrace]!" She summoned multiple orbs which chased Iapetus even if he tried to dodge. Audrey distanced herself to ensure that she won't be hit by his weapon. "[Malevarious]! [Starfire]!" She combined the elements of the stars and fire to burn through Iapetus even if he uses gray border.
Iapetus easily dodged the furious chase of [Souls Embrace] and the charged laser of [Malevarious]. Audrey worked on changing the trajectory constantly while adding continuous strain to her mind. However, she never ended her relentless attacks. Since [Malevarious] missed despite changing its trajectory slowly, Audrey cancelled the cast to save mana and activated multiple spells to summon various element spikes from every single direction of Iapetus and begin converging as soon as they were summoned. He then followed it up with another [Malevarious] using the same exact elements. The first strike finally landed as a nature spike struck Iapetus and injected deadly poison in an instant, slowing him down which got him hit by multiple [Souls Embrace]. However, he barely dodged [Malevarious] and got himself healed back up using the power of life. While in the end of that attack, he was completely unscathed and cured from the poison, being hit by an underling of Preeliance was something he couldn't easily forgive himself with. He began activating an ability that made Audrey remember something from Draxus's battle against him without magic. "I won't let you! [Souls Embrace]! [Malevarious]!" Being interrupted from activating his trump card, Iapetus was forced to dodge and chase Audrey to stop her from making attacks for the time being. He intended to make her waste mana despite having a massive pool of it. Audrey was keeping tabs on the metallic knights which started to march towards the Sentinels, the distance between the two groups is starting to shrink as there was only a kilometer between them now. Which meant, Audrey has to stall the army while fighting against Iapetus all alone. This she considers as major trouble.
A crazy dogfight in midair occurred as Iapetus continuously chased after Audrey, dodging every attack she sends as he continues to speed up using life energies. The reason Iapetus is slowly gaining ground against Audrey is due to the fact that he can absorb one metallic knight using death energy to convert it to life energy. Thus he has limitless potential as of the moment. Audrey continued to launch attacks such as thousands of elemental spikes, [Souls Embrace], [Malevarious] to both slow down Iapetus and damage the army. She has mostly eradicated half of the army, but due to Iapetus chasing her, she was about to run out of mana after continuous usage. "You're finally running out of time! With this, I shall finally get rid of you!" Audrey's speed dropped significantly which made her resolve herself completely. "Drax, allow me to borrow this..." She hid the hakkero momentarily and brought out a tarot card which came from Draxus. She could choose to drink liquid mana, but she doesn't have enough time as Iapetus could catch up while she's drinking it.
"[Fortune Card I]! [Magician]!!!" A powerful aura covered Audrey as she instantly regained all of her mana through a great roaring pressure. Despite feeling the great power inside the borrowed fortune card from Draxus, to which he did lend with permission, Audrey was starting to feel the compensation immediately. She was on the edge of breaking down from the pain of using a tarot card, but she forced herself to push through and never yield in front of death. "Guh!! So that's how you want to play it! [Gray Border]!!!" Iapetus activated his trump card as he was being pushed back by the aura Audrey had brought out. He tried to close in to make Audrey enter his range of the [Gray Border], but since Audrey already knew what would happen if she entered the range, she distanced herself instantly and activated multiple magic attacks. "Rain from the sky! [Pillars of Death]!" She raised he staff while distancing herself to summon multiple rays of light reflecting different elements to strike down toward the ground. Iapetus easily dodged the pillars but his army wasn't so fortunate to get through the endless lasers from the sky. Audrey brought out the hakkero once more and activated it at full power. "[Revelation]! [Malevarious Ultima]!" Audrey merged all elements that she can use and pour it towards the hakkero. She then fired it off towards Iapetus which was dodged easily. Without any way to lock Iapetus position, Audrey had to quickly think of ideas on what to do against him, it was then she struck an idea which she found extremely risky.
Audrey dropped to the ground pretending to have been taken over by the compensation of the card and dispelled every single ability she had excluding the magician tarot card. She hid the aura that was brought out and waited for Iapetus to come down to the ground.
Iapetus landed slowly on the ground while keeping Audrey in range of his [Gray Border]. The numbers of metallic knights had already dropped to a few thousands from Audrey's relentless attacks, thus there is only one way to finish this. Just as Iapetus's feet touched the ground, multiple roots came out from the ground to root him effectively. The ones touching his black side started to decay while the ones touching the white side started to let him go as if he's being obeyed. However, Audrey kept at it, making sure that he doesn't move for a few seconds only. To completely ensure it she left the range of [Gray Border] just as she was standing up. She was smiling, as she brought out her hakkero. "[Revelation]! [Malevarious Ultima]! Full power!!!" A charged laser struck through Iapetus as he was locked in position from Audrey's constant rooting. The laser passed through most things and ended up shooting towards the horizon of the skies, killing half of the knights due to its width and tripling from her standard use. This was only possible due to the [Magician] Card she borrowed. However, just as the death laser ended, the death side of Iapetus is still active. It quickly regenerated the side of life but just as he tried to control Audrey, Iapetus returned to normal. However, that doesn't stop him as he didn't hesitate to charge towards Audrey with the spear. Audrey was too slow to process the sudden attack due to his absurd recovery and dropped both the hakkero and staff as she stepped back with her arms trying to cover herself from the spear. But just as the spear was about to touch her, two swords had deflected the spear back upwards and broke Iapetus's grip. Jay entered between them and stabbed him in the chest with his bladed wings. "This is payback!" Iapetus stepped back to get the bladed wings off of him. He then raised his arm to the sky and disappeared in an instant.
"Audrey! Are you alright?!" Jay quickly checked on Audrey to see if she received any scratches, but he breathed a sigh of relief as he knew that she was alright. "Yeah... But I think I'll leave the rest of the work to you... There's still a thousand of them left. I can't cast a single spell for a while..." Jay simply smiled as he let Audrey lay down on the grass and rest. Ulysses then stood beside him and faced the metallic knights. "I've heard of you once, getting to fight side by side with a Sentinel sounds like a fun time." Jay laughed lightly as he pushed towards the army of metallic knights.
In the meantime, the army of Quisterion had arrived to support the Sentinels under the command of Olivia. They had quick work of the enemies that remained in the shoreline while their hero had dealt with the remaining knights along with a [Sentinel]. After eliminating the knights, they went towards facing off the devil's army at full strength. Audrey however, was retreated to the castle of Quisterion to rest with the help of Wendy and her group.
