Freja and Elaina stood beside each other with their weapons drawn, ready to attack. They both covered their weapons in black flames with Freja also adding a bit of blood to the mix. She coated a thin layer over her sword allowing it to extend additional blades of blood.
"Freja do keep in mind my attacks are quite explosive." Elaina didn't want to accidentally hit Freja with one of her charged attacks.
"Don't worry about me." Freja already knew what the weapon did thanks to her system, but still appreciated the heads up.
"You two coming or what? I'm already getting bored." Katarina was examining Klaus' body, trying to get used to moving since it wasn't her own.
"How dare we waste a god's precious time. How about we help by sending you to the underworld where you will have all the time in the world to count the screams." Freja said as she initiated the attack with a simple slash to test the waters.
Without even looking Katarina blocked the blow with just her hand as she yawned lazily.
"Is that all you got?" Katarina was thoroughly unimpressed, making her wonder why Klaus even switched in the first place.
"Tch, don't be so confident." A blood blade aimed at Katarina's face shot out but was stopped with her other hand.
"I'd say take your own advice!" Katarina hated Freja's attitude as it oozed arrogance and blind confidence in herself. She should be terrified, not purposely trying to defy a god.
Katarina kicked Freja in the stomach, almost breaking Klaus' leg out of sheer power. Freja was launched back, but Elaina extended her arm for Freja to hold onto. Using that momentum they spun around redirecting Freja back at Katarina.
Freja spun in the air creating a drill shape with her black flames. Trying to enhance her flames as much as it would allow her, her flames got so hot the ground around her began to melt.
"When will you understand that my power is beyond your comprehension." Katarina was getting sick of attacks that would do absolutely nothing to her. However, she forgot that she is in a normal human body, so she was limited to what it could handle.
Holding her hands out to directly stop Freja's attack, she misguidedly took the attack full on. Klaus's bones made dangerous sounds as his flesh was getting burnt away. Although she didn't feel the pain, if she held the attack for any longer she would no longer have a body to possess.
So she tried redirecting Freja's attack while moving away before she completely lost her arms.
"Tch."
"Looking a little hot there." Freja was taking the chance to provoke Katarina whenever she got it. The backlash from her attack has thrown her back a tad, so she desided to distract the prideful god instead.
"Shut u-." Katarina tried to respond, but was cut off when Elaina appeared from behind her, spinning her axe. Using the flat side of it, she swung it like a baseball bat sending Katarina flying into Freja.
Using her free hand Freja grabbed Katarina's face and smashed it into the ground. Freja then concentrated all of her flames into her hand, blasting Katarina's face.
While Freja was burning Katarina's face, she used her other hand to wield her sword. She then etched a circle on Klaus' body putting some sort of hex on him.
After the circle was finished Freja jumped away, letting Elaina who was coming from above do one big swing right into Katarina's chest. This by far was her most powerful hit so far as she spent roughly 20 seconds spinning in the air in order to make her axe as hot as the sun.
She was barely even able to wield the handle for how hot it was, but the armour she wore kept her safe from the overbearing heat. The surrounding environment however, were completely turned to ash in a 1000 metre radius.
Katarina wasn't holding up too well as Klaus' face was now gone and the heat from the axe was at work disintegrating the rest of his body.
Elaina's axe finally made contact with Klaus' body, causing cracks in the earth to extend out over 100 metres, but that was nothing compared to the centre point, where the crack ran so deep that magma erupted. Klaus' body was consumed by the magma leaving no sign of Katarina.
It was as if she stopped possessing his body as soon as Freja got a hold of her.
"Elaina get back!" Freja had retreated to the air a fair distance away, and now with a bird's eye view she had noticed something.
A black pool was forming where Klaus' body was and Freja didn't know if it was a dark magic spell or if his body itself actually turned into dark magic after being destroyed. Nonetheless, Freja wanted Elaina to get away quickly in case things take a turn for the worst.
Elaina, using her bat wings, flew in the air to join Freja who was straight-up levitating.
"I will never understand how you fly."
"I'll tell you later, but I fear the battle is far from over." It was rather simple how she flew but now wasn't the time. The black swirl in the lava was getting bigger with each passing second. It didn't give off any mana reading, but Freja definitely felt something fill the air.
It was like the cold breath of death brushed over them causing their hair to stand up.
"I thought my sealing circle would have some effect, but it seems like it doesn't apply to dark magic." Explaining what she etched into Klaus' body, Freja hoped it would prevent him from using any skills that may get him out of the situation.
"So that's what you did. I think it's better to call it a mana seal since dark magic is emotion and all. I don't think such magic for sealing someone's emotions exists, unless they are brainwashed." Elaina liked Freja's idea, but it seemed like it was too little to impact the current situation.
While they were talking, a black sludge suddenly emerged from the magma sucking it all into its own body.
"What the fuck is this?" Freja didn't know how to fight this thing that was, as from what she could see, made of pure dark magic. There was no way she would be able to get close without becoming a lifeless husk.
"Elaina, I don't like our chances." Freja tried to think of a way out, but depending on how this thing acted, there wasn't any viable solution.
"Hang on it, doesn't look like it will fight." Elaina enhanced her vision with demon essence which allowed her to see even mana particles. A golden light she had never seen before was beaming into the sky, bending in the direction of the human territory.
"What do you see?" Freja saw the slight pink glow in Elaina's eyes.
"I think it is preparing a teleport, but it's using mana the likes of which I've never seen before. I think it could be divine magic." It was only an assumption, but considering the fact they fought a god just now, it didn't seem too far off.
"Interesting." Freja was greatly intrigued by the divine magic and thought maybe she could try to harness it.
A few moments later and the black sludge suddenly vanished in a blink into thin air, leaving no traces behind.
***
<Captial city of Elysium>
Deep underground the black sludge appeared in a confined room slowly melting away. It evaporated into nothingness, slowly revealing a body completely covered in burns.
"Wake up Klaus!" Katarina's voice echoed inside his mind forcing him to wake up. Gasping for air, he regained his bearings, realising he no longer was in the Demon Lands.
"Argh fuck!" Feeling the pain kick in from the burns, he wondered how the hell this happened. He let a god possess his body, but instead of defeating Elaina and Freja, he got 3rd-degree burns.
"Your body is too weak for me to use. I tried using divine magic, but your body is so pitiful that I couldn't even conjure up a spell." It was a complete waste of Katarina's time and only served as an embarrassment.
"You said you could bitch! How was I supposed to know you would be useless if you took over my body." Klaus did not want to take any shit from Katarina who told him it would be okay.
"Hmph, I didn't think the constitution of a human would be so weak. If it was any other race I would have been fine." Katarina had done possessions before, but it had always been on other races who tend to be stronger.
"Then why don't you fuck off then?!" Klaus took it as an insult as he spent countless hours preparing himself, but now that chance was ruined. The whole continent is going to find out what he has been doing causing a war.
"Do you think I can go anywhere? You are the only person that can even wield this cursed power, now stop sobbing and get moving."Katarina had enough of Klaus' attitude so she wanted him to hurry up and move forward with the plan, not that he had any other choice.
"Whatever, I will get on with the summoning and you will give me the real Katarina back."
"A deal is a deal after all."
