-With Rossweisse-

"The Red Dragon Emperor is the only one who can achieve the necessary power to wield Mjolnir. Tell him to boost his power three more times before transferring it to the Hammer of the Thunder God Thor and putting a stop to Loki and Ragnarok," Odin's voice told the Valkyrie.

"Issei, you need to boost your power three more times, and then you can take the Hammer of Thor and end this," Rossweisse shouted out, relaying the information Odin gave her.

A grin grew on Issei's face at the prospect of wielding such a powerful weapon and a "Boost" could be heard coming from his armour. He stood up from where he was and flapped the draconic wings the armour gave him.

As he approached another "Boost" could be heard coming from the armour. At this point, Loki felt the increase in the Red Dragon Emperor's power and began to worry. 'If that brat gains any more power he will be able to take hold of Mjolnir, I have to act quickly," Loki thought as he began flying towards the armoured teen.

"Not so fast you bastard," Saji called out as a light blue line wrapped itself around Loki's leg, preventing him from getting to Issei.

"You insufferable brat. Fenrir, I think I found you a new chew toy," Loki called out to his son with a malicious grin. Xenovia and Kiba quickly dashed to aid Saji, protecting him from Fenrir's attack while he held Loki in place.

Fenrir let out a howl and pushed off in a massive leap. Xenovia and Kiba readied themselves for a fight once again before they gained a look of confusion, seeing Fenrir flying high into the air. A look of horror appeared on the members of the attack team's faces as they saw Fenrir flying straight towards Issei.

"Issei," Rias' frantic fear-filled shout rang out over the silent battlefield as Fenrir closed his massive jaws around the teen.

Fenrir threw Issei's body to the ground like a discarded piece of meat. Issei's armour disappeared revealing the damage the giant wolf did.

There were three large holes in his body where Fenrir's teeth pierced him. Rias quickly ran to where he fell and gently took him into her embrace. Wendy, Asia Rossweisse and Tsubaki stood in shocked silence while Xenovia, Kiba Irina, and Koneko shouted out in rage at the beast that killed their friend.

"You'll pay for that you bastard," Xenovia shouted in rage as she slashed a large gash in Fenrir's leg.

"I'll pay you back a thousand times for what you did," Irina shouted as she formed a blade form her light and pierced the God-Devouring Wolf's back leg.

Saji and Kiba shouted in anger and rage as they both sent devastating attack at the wolf but they were intercepted by the two sons of Fenrir.

Koneko rushed forward to attack Fenrir she was intercepted by the gigantic form of Midgardsormr. Koneko's punch didn't have much effect on the Dragon King and he swiftly swiped his tail at her, causing her to jump up high.

This proved to be an error as Midgardsormr readied a breath attack. Luckily for the Nekoshou Akeno was behind her in seconds and pulled her out of the way of the stream of fire that came from the enormous Dragon's mouth.

"I will not lose another person precious to me today," Akeno said with a mixture of rage and sorrow in her eyes as yellow scales started forming on her arms and face. Akeno raised her scaly hand that began resembling a claw into the sky and a magic circle formed with the head of a dragon in the centre.

A barrage of golden-yellow lightning bolts rained down on the Dragon King and pained roars could be heard coming from him.

'This power…' Midgardsormr began thinking before his attention was pulled to a massive build-up of magical energy as a red aura encased the battlefield.

-With Natsu and Grayfia-

"This is bad. Going by the amount of power she is putting out I don't think she plans on surviving her own attack," Grayfia said with a concerned expression and looked at Natsu to see if he had a plan.

"It's disappointing that they believe him to be dead and that they don't see the clear way to get him to survive. Let's go and show them how it's done," Natsu said and offered Grayfia his hand, keeping his eyes on the battle below.

Grayfia quickly took his hand and he pulled her close to him. The next thing Grayfia knew was that they were flying through the air at insane speeds.

-With Rias-

Loss, sorrow, regret, anger and hate. These were the emotions Rias felt as her eyes shifted from Issei to Loki with tearstained eyes.

"I vow this in front of everyone here, I will ensure you pay for taking what is mine. You took my Issei away from me and now I will take everything you hold dear," Rias said as the red aura thickened and her magical output reached its absolute maximum.

"No Rias, don't do this," Akeno said in concern for her friend.

"Rias, do you think this is what he would want?" Sona asked as she tried to penetrate the heavy aura in order to snap her grieving friend back to normal, but was unable to.

Just before Rias could release the power she had built up and destroy the target of her misery warm arm embraced her and another hand brought her head into a warm chest.

"You still have a lot to learn on how to deal with your emotions in a high tension situation," a deep voice whispered to her as her magical output plummeted to her normal levels as her eyes widened in shock when she recognised the voice.

"Wendy, Asia, combine your healing powers and help Issei recover," Natsu instructed. The authority and confidence in his voice quickly snapped the two healers out of their shock as they rushed to Issei and started pouring all of their magic into healing him.

"And who might this be? Doesn't matter, Fenrir why don't you take that Hammer and play a bit?" Loki asked before giving the suggestion to Fenrir.

Fenrir let out a menacing howl that caused the three that were attacking him to back off a bit in fear of another revel of even greater power. Fenrir leapt into the air but didn't get too far as glowing chains began to surround his giant form.

"What is this magic sigil?" Loki asked as he saw a purple octagon forming beneath his son.

"The magic chains of Gleipnir, what's going on?" Rossweisse exclaimed in surprise as she recognised the chains that thee dwarves forged to bind Fenrir.

"I might have had something to with that," a smooth voice said from the top of one of the peaks.

"Kuroka," Koneko said as her eyes fell on her sister.

"I'm so happy to see you have accepted your power and that your ears and tail had made an appearance," Kuroka said with a genuine smile.

"Maybe, but I will never be like you Kuroka," Koneko said as she steadied her gaze on her sister. No one bar Natsu saw Kuroka flinch at the last words that Koneko said since their attention was on Loki who shouted in anger.

"The nerve of a lowly cat devil to betray me," Loki shouted as he sent a devastating beam of magic towards Kuroka. Once the beam was close to its target, however, it simply burst into multiple harmless fragments.

A bespectacled young man with blond hair and a strand across his face dressed in a business suit stood behind Kuroka with what looked like a two-handed sword with a round pommel at the end and a huge cross-like shaped guard and a long blade with golden coloured edges, extended to his right.

"Salutation, my name is Arthur of the Vali team. Lord Loki, we will be taking custody of Fenrir from this point onward," Arthur said as he turned his gaze to Loki.

"And why would you do that?" Loki asked in confusion and an attempt to hide his anger at the cat devil's betrayal.

"Vali really likes the fangs that can kill a god and he really wanted a new pet," Kuroka said with a giggle.

"Tell your master you will regret this betrayal," Loki said as his power began manifesting around him.

"I think the only one here who will be regretting anything will be you," Kuroka said with a grin as she quickly cast a glance at Natsu who was still comforting Rias as Wendy and Asia healed Issei. While she was talking Arthur pulled out the other sword he had as he dispelled his massive one and imbedded the glowing sword in Fenrir's head, using t's power to control legendary creatures to ensure Fenrir would comply with Vali's wishes.

"Fare thee well everyone, ta-ta," Arthur said with a small bow before he and Kuroka disappeared without a trace.

-With Rias and Natsu-

"Now take a deep breath and look at the situation with a clear mind, Issei is not dead. I won't help you here unless I don't see any other option. So get up, believe in your power and the power of your peerage, believe in the power of your allies and give them orders. One of the enemies is already gone. And don't go trying a suicide attack again," Natsu whispered to the red-haired heiress of the Gremory Clan.

"Thank you," Rias said in a soft voice after she took a deep breath. A smile came to her face as she heard an all too familiar "Boost". In front of her stood her precious pawn with his left arm encased in a red gauntlet and the hammer Mjolnir in his hand.

"Xenovia, Kiba, Irina and Rossweisse deal with Sköll and Hati. Wendy and Asia, heal whoever needs it as soon as they are injured. Koneko and Akeno, deal with Midgardsormr. Issei and I will deal with this deranged god," Rias said in a voice filled with authority and confidence.

"Saji, help with the little wolves, Tsubaki, aid Akeno and Koneko while I hep with the big boss," Sona said with a small smirk as her friend finally came to her senses thanks to Natsu.

With renewed vigour and a boost in both confidence and power, the attack group launched their final assault on Loki. Kiba and Rossweisse faced Hati, with Kiba charging in and Rossweisse providing backup with either a barrage of magic or a barrier to block some of the wolf's attacks.

Saji made his appearance in the battle when he pulled Hati with his Sacred Gear wrapped around its leg into one of Kiba's many swords that covered the mountaintop.

Xenovia and Irina showed their years together working for the Church with their excellent teamwork in taking on Sköll, weaving attacks between the two of them and covering for one another when either slips in their movements.

Akeno had a grin on her scaly face as she saw the scales on her hands and arms. 'Strong emotions are the easiest way to manifest the Dragon's power however a state brought on by emotion is not a complete state,' She remembered what Natsu said to her, Xenovia and Grayfia when he trained them in their Dragonoid form.

She quickly brought her hand together with her arms extended and as soon as her two hands met a resounding clap of thunder sounded around the battlefield and a massive bolt of golden-yellow lightning shot towards Midgardsormr.

Koneko covered her hands in a bright blue aura and jumped up to the Dragon King's eye level before connecting a heavy blow with its head. Midgardsormr retaliated with a stream of fire from its mouth but Tsubaki jumped in and summoned her Mirror Alice to reflect the breath attack once again.

"Let's keep that bastard in one place while Issei prepares for the final blow," Rias said as she turned to Sona with the anger she felt for the god still evident in her eyes.

Sona didn't give a verbal response but rather sent a massive water Leviathan to attack Loki. Rias joined in on the assault. She swung her arms in a circular fashion as she gathered her Power of Destruction before releasing a devastating vortex of red energy at Loki.

Without the help of their Father Hati and Sköll were driven off and Akeno, Koneko and Tsubaki managed to beat Midgardsormr to a state where the great serpentine Dragon seemed to be unconscious on the ground, leaving only Loke as the last enemy to deal with.

"Boost," Ddraig's voice called Mjolnir started to light up in with golden runes.

"I will strike you down where you stand you insect," Loki shouted in rage as he saw his allies were gone. He created a magic circle in front of him, fully intent on sending Issei to his death. A golden bolt of lightning followed by a bright blue orb connected with the circle and instantly destroyed it.

A stream of water and rings of light connected with Loki himself, causing the god to stumble.

"You meddling kids," Loki shouted in anger as he began ascending to get out of the range of the devil's attacks. A blue line wrapped itself around his arm and prevented him from getting away as multiple purple, needle-like missiles hit Loki in the back courtesy of Rossweisse.

Loki let out an enraged shout and sent a sword of purple light strait at Issei. Xenovia and Kiba both jumped in front of Issei and blocked the blade of purple energy.

"Transfer," Ddraig's voice called out as the mighty hammer of Thor, Mjolnir, enlarged in size and power. Issei swung the massive hammer at Loki. As the mighty hammer made contact a magic circle of blue lightning formed and sparks flew all over the place.

"A plague on all your houses, a plague on your houses, may you suffer greatly before death," Loki said as the magic circle engulfed him. And then he was gone.

Natsu walked over to Xenovia and Akeno and gave each of them a hug and a kiss before turning to Grayfia and taking her hand. With a quick smile, he disappeared into a black smoke with Grayfia.

"Why the hell does he always do that?" Issei shouted, causing everyone to laugh.

An angered roar sounded from behind them and they saw Midgardsormr preparing to attack. But before the beast could let its attack launch it exploded in a murky green mist.

"Never assume the battle is over until the enemy is truly defeated," Sairaorg said as he made his appearance.

"Sairaorg?" Issei exclaimed in surprise as he turned to the strongest young devil.

"You seem pretty string there Red Dragon Emperor, I'd like to fight against you and Rias in a rating game one of these days, to find out who's number one," Sairaorg said with a smile as he placed his fist on Issei's chest.

"We don't plan to lose that fight," Rias said as she walked up behind Issei.

"Should be a lot of fun," Issei agreed.
