Today was the day with the battle against Thor.

Even though this was far from the girls' first battle, they still felt butterflies in their stomachs.

The battle between the Amaterasu girls and Thor is taking place at an arena in Odin's world. For today, everyone went to Odin's world to see this fight. There were even some residents of Odin's world watching.

Kizuna, the goddesses, Reiri and Kei, Masters, Grace and everyone else were there to show their support to Aine and the others. With so many people that believed in them, there's no way for them to lose.

"… Alright, I guess it's time we head out."

After that, the girls headed out towards the arena Odin had prepared for this battle. It was a circular arena that had the audience stands high so that they wouldn't be easily hit. On the other side was the silver haired god, Thor.

His eyes seemed to say that he respected that the girls didn't run away, but also said that there was no chance of him losing.

"If you four give up now I won't have to hurt you."

"Who's going to give up at this point?"

"Heh, I guess that's true. Since you're all girls, I'll try not to damage your bodies too much, but don't mistake that for going easy."

After a few seconds, Odin showed up between Thor and the girls. She was going to be the referee for this battle.

"If Thor admits defeat or is knocked unconscious, then it's the girls' victory. Of course, it's Thor's win if the same happen to the four girls. If no one has any objections, then get ready… start!"

The girls quickly equipped their Heart Hybrid Gear. As soon as Zeros was equipped on her body, Aine advanced forward in order to engage in close quarters combat with Thor, who still seemed quite relaxed.

"Wa!"

To Aine's surprise, Thor also advanced forward, so they met in the middle of the arena. They both stopped on their tracks and faced each other for a fraction of a second. Thor pushed his finger against Aine's forehead, she reflexively tried to step back, but ended up miss-stepping and fell on her butt.

"Don't come at me if you don't have the resolve to trade blows."

Thor said as he ignored Aine and headed for the other three.

Hayuru was the one to face Thor next. She tried to slash with her sword, but Thor dodged by jumping back. Hayuru then used Neros' Blades to keep the fight at long distance.

What Thor didn't imagine was that he was being directed by Hayuru. As he kept dodging the Blades, Thor approached Sylvia.

"What?"

"Heeei!"

Taros' big hand grabbed Thor by the head and threw him to the arena's wall, making a loud crashing noise. Yurishia then took aim and fired a full powered shot at Thor.

"That was easy."

"As if that would be enough for us to win."

Not long after Hayuru's retort to Yurishia, Thor shot lightning towards them. Luckily, they had already foreseen that and were able to dodge.

Thor made a dash towards Yurishia. Since she was mainly focused on long-range attacks, Thor figured she'd be weak in close-quarters combat.

However, right as he got halfway to Yurishia, Thor took a punch to the face. The one who landed that punch was none other than Aine.

"Haaaa!"

Even though Aine focused all the strength on that punch, all it did was make Thor take a step back. So Aine knew she had to retreat before he countered.

"Damn, I think that hurt me more than him."

Aine said as she held her own hand. She was feeling a lot of pain on her hand, but the adrenaline from the fight was suppressing it. Meanwhile, the other three girls gathered near Aine.

Thor touched his own face, as if evaluating not only Aine's punch, but all the attacks until now.

"I guess you all weren't just sitting around thinking you could be me with willpower alone, so I'll give you props for that at least. But if this is all, I recommend you four give up right now."

However, this didn't intimidate the girls. Even though it was just for one week, they did train with Osiris to win this battle, so now was the time to show the results of that training.

The Amaterasu girls looked at each other, they were all thinking the same, so there was no need to say it out loud.

Hayuru quickly send her Blades to attack Thor. They didn't have nearly enough power to defeat a god, but they were still irritating.

While Thor was a little distracted by the Blades, Aine dashed forward. Thor had actually noticed it and could have stopped her if he so chose, but figured it wasn't worth the effort.

Once Aine was close, it looked like she was going to try punching his face once again. Since he wanted to end this, Thor figured he'd head-butt her punch, as it would surely hurt her the most. Still, he figured he should hold back enough so that the worst that could happen to Aine was a broken hand.

"Eh?"

But what he didn't expect was that Aine would back down last second, so he head-butted nothing. Still, that didn't help the girls in anything.

That's why, with a single second of delay, Hayuru came slashing her sword towards Thor. His body sensed the danger before his mind did, so his body moved on its own. But, due to his bad posture by head-butting the air, all he could do was extend his hand and grab the sword by the blade.

That should have been fine, but, for some reason, blood was flowing from his palm where he was grabbing the sword, even dripping on the ground.

Taking advantage of Thor's confusion, Aine punched him in the stomach. Once again, it should have been fine, but Thor did feel a strong impact this time.

Before Thor could do anything, both Aine and Hayuru jumped back. It was as if… they were gaining distance from Thor. The god then remembered that he hadn't seen the other two in a while.

"Now!"

"Fire!"

Yurishia and Sylvia were behind Thor, one was at his diagonal from the left while the other was to the right, making so that he couldn't completely avoid both shots.

They both took aim and fired at Thor. He might have been able to dodge if he flew or jumped high enough, but his pride made him try to defend.

However, he soon noticed that it wasn't a good idea and tried to dodge, but, due to his waste of time earlier, he was still hit and took some damage.

"… What? What's happening?"

Meanwhile, Kizuna in the spectator stand seemed to notice what was different.

"They are…"

"Oh, so you noticed, Kizuna?"

Osiris was the one who came from behind Kizuna and said that. Being the one who trained them for this fight, Osiris should know what's happening the best.

To avoid the risk of Thor hearing something, Osiris pressed her body on Kizuna's back and whispered in his ear.

"Remember that technique of using your energy that I taught you? I also taught it to them. Since they didn't have a lot of time to practice, they tried to specialize in one area for this battle. Aine strengthened her physical attacks, Hayuru covers her sword and Blades with energy, and Yurishia and Sylvia can shoot out an incredible amount of energy at once."

"I see. But is that really enough for them to match Thor?"

"Normally not, but it's not hard to see that Thor was underestimating them, and that gives them a chance. But still, Thor dodged that last attack, meaning he won't underestimate them as much anymore. There's also the matter of, unlike you who has a low energy consumption, they can't keep using it as much since they also have to power their Heart Hybrid Gear. In short, if they're going to win, they have to do it quickly."

Back down in the arena, just as Osiris said, Thor was getting more serious. He send four lightning strikes, one to each girl, which made them dodge out of the way.

"I'm still in the process of figuring out what you all did, but I'll admit you all aren't as useless in combat as I thought. If I had taken that last hit, maybe I'd be done for, so I won't give you all another chance."

Having said that, Thor focused his lightning not to attack, but to defend. His body was covered in blue lightning, one didn't even need to test to know how strong that defense must be.

Even the girls knew they couldn't break this defense, but they also knew they'd inevitably lose if they didn't do something about it. That's why Yurishia spoke up.

"Sylvia and I will do something about that protection. So you two watch for an opening."

Sylvia nodded, showing her agreement. Yurishia and Sylvia dashed towards Thor while Aine and Hayuru stayed behind.

Thor shot lightning towards them, but they dodged. Sylvia's giant Taros tried to attack Thor while Yurishia distracted him with some shots. However, Thor didn't pay any mind to Yurishia and focused on battling Taros.

Of course, Taros' strength couldn't compete with Thor's. The god grabbed Taros' arm and started twisting it as if he intended to rip it off.

But even that wasn't exactly out of the plans.

"Now desu!"

Yurishia combined her Differential Frames into one and shot at Thor, who was forced to release Taros to defend. Even so, the blast still send him flying towards the arena's walls.

But Thor got up not a second later. This marked Yurishia and Sylvia's best chance.

"Sylvia, let's go all out now."

Yurishia aimed her Differential Frames while Sylvia aimed her canon. They couldn't give him time to dodge, so they fired immediately.

Both their beams of light combined into one and hit Thor's defense. They were being able to push back his defense.

"Gah! Damn!"

At this rate, Thor really would get cornered. Because he acknowledged that, he felt like it was only fair to use it now. If anything, he could say they were deserving of seeing it.

"Sylvia, let's give it our all."

"Right desu!"

They promised they would create an opening for Aine and Hayuru, and so they would do.

They poured everything they had in this shot. They would become unable to continue fighting, but that's alright.

A loud explosion sound was heard. Dust covered Thor as Yurishia and Sylvia fell to the ground. They were both unconscious because they used large amounts of energy, making their hybrid count well in the danger zone, but it wasn't at the point they would die yet.

Odin quickly moved and carried both Yurishia and Sylvia out. They couldn't fight anymore, so she let them rest.

Meanwhile, everyone was waiting for the dust to settle and reveal Thor's state. That only happened after five seconds.

What appeared was Thor, on his knees, but not defeated. His protections was gone, but something else appeared. It was a hammer.

"I guess I should have taken you four seriously from the beginning. You know that this isn't just any hammer, right?"

Even those who didn't know much about gods and mythology couldn't not know this hammer. It could be nothing than the legendary hammer, Mjolnir.

"That hammer… it's going to be trouble."

"You can say that again. Still, looks like this is the end. It's do or die."

Thor was playing around with Mjolnir, throwing it up and down. Even though he knew he had to take this seriously, it looks like he gained some confidence back now that he was using his hammer.

A second later, the three of them dashed forward. Hayuru's Blades met the strike from Mjolnir, but were easily deflected.

Aine dodged one of Thor's hammer swings and tried to get him in an arm lock for Hayuru to attack. But Thor shocked his own body, forcing Aine to release him.

Thor then hit the ground with Mjolnir, creating a literal shock wave. The lightning hit Aine and Hayuru, making them both fall to the ground.

"Well, now you should see that you never had any chance really. How about giving up now?"

"We're… not done… yet!"

Even though her legs were trembling due to the previous electric attack, Hayuru still stood up and faced Thor.

Since he held some respect for that action, Thor decided to fight her. That said, he wouldn't hold back, but that was also something Hayuru wanted.

Just as Thor was ready to attack Hayuru, she made the Blades come back and stab his back. One of them hit the elbow of the arm that was holding Mjolnir. With that slight opening this feeling of pain created, Hayuru slashed Thor's chest.

The wound she inflicted wasn't deep, but it still made Thor's chest feel like it was burning. Hayuru then circled around him and tried to attack again, but Thor was ready for it this time.

"Don't you think it'll be that easy!"

With sound of thunder, Thor used his free hand to punch Hayuru's stomach. The hit was loud and made Hayuru unconscious with sheer strength.

But Thor didn't even have the time to rejoice the fact that there was only one opponent left.

Behind him, Thor could feel something. He then realized that Hayuru had circled around him not to try and hit him, but because, when she was defeated, he'd be in a bad position to defend against the next attack.

"Haaaa!"

Thor could only see her from the corner of his eyes, but he noticed that Aine's hand was enveloped in some kind of energy. He finally realized what had made up for the difference in strength between them.

Thor tried to swing Mjolnir, but he was in a bad position and Hayuru's Blades were still piercing him, so he couldn't properly move his arm and didn't have time to switch to the other.

Even so, Thor is still a god. Aine's punch made contact with Thor's face at the same time his Mjolnir made contact with her chest.

A sound much louder than before echoed around. Next second, both Thor and Aine were fallen to the ground. Aine had coughed up some blood, but they would later discover that she was fine.

Odin went there to check out what had happened. She noticed some movement from Thor.

"I-I'm still-"

But then, she hit the back of her lance on Thor's face, knocking him unconscious.

"Unexpectedly, this ended in a draw. Wow, what a great battle. Now, let's let the participants take a rest shall we?"

Everyone in the spectator stands gave a round of applause for the great fight they had just seen. While they both also clapped their hands, Kizuna asked Osiris.

"Say, didn't Odin…?"

"Yeah, I'm pretty sure she did. But let's not say anything, alright?"

Only Kizuna and Osiris seemed to have noticed Odin's little help at the end, but decided to keep it to themselves.

And so, the curtains were closed on this battle.
