With the swipe of his hand, Loki laid waste to an entire city. Black smoke filled the sky as Loki burned over Hell. His son, the wolf Fenrir, laid waste to all of Hell, burning and killing until finally, they were met by the Gremory Peerage. 

"Ah... You came..." said the God in his usual calm voice, "I was beginning to this that all of this..." 

He waved a hand behind him, showing the destruction that he had caused. 

"...Was going to go unnoticed."

"It's over, Loki!" yelled Rias, "Surrender now and return to Warenai, or die by our hands!" 

"Don't think it'll be so easy..." growled Loki. With the snap of his fingers, Loki's blue Norse Magic Circles appeared, which summoned the Sons of Fenrir: Skoll and Hati Hroovinisoon and multiple clones of the Legendary Dragon Midgardsormr. 

"You see, I've learned from my previous mistakes. Evolved, if you will," grinned Loki with menacing confidence, "And once I'm done here with you, I will raze Hell to the ground and kill Odin, setting Ragnarok free! I will be the king that stands atop the Universe itself!" 

"Can we beat this guy Rias?" asked Issei, "We barely managed to beat him last time!" 

"Don't worry," replied Rias, "Azazel's promised us reinforcements, but for the time being, let's kick this guy's ass!"

"Damn it!" yelled (y/n), "I-I have to help him!" 

(y/n) thought about going, but he knew he couldn't. If someone saw him out, he could compromise Rias and the others, not to mention also putting Xenovia in danger. 

(y/n) thought for a moment and weighed the risks before finally deciding to go and help. 

He moved to pull the door handle, which would allow him to leave, but it burned him to the touch. (y/n) recoiled his hand and hissed in pain as he saw the Gremory Family Insignia on this door's handle. 

"She must've put a spell on the house that prevents me from leaving!" groaned (y/n).

"Damn it!" yelled (y/n) again, pounding his fists on the door. 

"I could help you, you know?"

Issei fired a Dragon Shot at Loki, but Fenrir and his Sons blocked it. They guarded Loki religiously, ensuring that he would never sustain damage. 

"Fenrir and his goons are blocking the way!" griped Koneko, "Were these guys this strong the last time?" 

"That's just what I was wondering..." said Rias, "We killed Fenrir for sure, so how can he be here fighting us now?!" 

"After I escaped, I came back to the original destination of our first battle and recovered Fenrir's DNA," said Loki, "I made him again, stronger than he was before and perfectly capable of putting you down!" 

The Legendary Wolf lunged forward at Koneko, who barely managed to dodge the deadly jaws before kicking him away. Recognizing the danger that was the Son of Loki, Koneko transformed into Nekomata Level 2 for the speed and power necessary for the upper hand.

Meanwhile, Akeno and Rias battled Skoll: The Wolf that Chases the Sun. Skoll swiped at them, but they were able to fly well above Skoll's range. The Sun Wolf opened its large mouth and fired a blast of yellow energy. 

"Akeno! Together!" 

"Right!" 

Rias and Akeno fired energy blasts of their own, locking with the beam from Skoll. Both of them managed to overpower Skoll and hit him with their attacks, sending him back. 

"I think this little doggy could use some punishment... Wouldn't you agree, Rias?" 

Xenovia, Kiba, and Gasper all fought Hati Hroovinisoon: The Wolf that Chases the Moon. Gasper attempted to hold the black-furred wolf with his shadows. For a moment, it seemed that Gasper was able to hold the beast in place, but his shadows turned into spikes and were suddenly launched at the others. 

"He must have a shadow manipulation ability like Gasper!" realized Xenovia as she skillfully dodged the rebound shadows. 

"This is getting harder than I expected!" growled Kiba. 

Issei, seeing his opportunity, charged the unguarded Loki. However, before he could reach him, one of the fake Migardsormr lunged out with its fangs. Thanks to the Scale Mail armor, Issei was fast enough to catch the snake before it could bite down. He summoned the Ascalon from his right gauntlet at cut the serpent's head off. 

"Take this!" yelled Issei, "Dragon Shot!" 

Issei fired his attack only meters away from Loki, but before it hit him, it hit what seemed to be an invisible barrier. 

"It's like I told you. I've evolved," bragged Loki, "No mortal can touch me! I am unbeatable! Unkillable! I... am..." 

Before Loki could finish, a blue blast came from behind Issei and struck Loki directly. 

Issei turned around to see their reinforcements in the form of Sona, Irina, and Rossweisse. 

"All right!" cheered Issei, "Backup's here!" 

"It seems like you're in a spot of trouble," said Sona in her usual monotone while blasting Skoll away with her water powers. 

"It took you some time to get here!" complained Rias, "What took you so long?" 

"It took a bit of convincing to get Irina's superiors to allow her to help, but a little word from Sirzechs and they were glad to send her down," said Sona. 

"In any case, I'm glad you're here!" smiled Rias, "But who was the one that hit Loki?" 

"That would be me!" said Rossweisse as she stepped forward, "Loki has covered himself in a Godly barrier that prevents any mortal from getting through! Thankfully, because I'm a Valkyrie, I'm a half-God and can pierce his barrier!" 

"Well, then the plan has changed!" Rias said, "Our goal is to protect you from Loki's attacks while you take him down!" 

"E-Everyone's going to be depending on me..." stuttered Rossweisse, "I've never been at the center of attention like this before..." 

Over near Xenovia and Kiba, Hati almost was able to capture Xenovia in his dark jaws, but a heavenly light blinded the Moon Wolf, causing him to miss his target. 

"Irina!" cheered Xenovia as the angel came down, "You made it!" 

"I sure did! Now, what do you say we put this puppy out to pasture?" 

"Oh yeah! Let's do this! Kiba!" 

"Right behind you!" 

Kiba plunged his sword into the ground to activate his Sword Birth. Multiple silver swords erupted from the ground and dug into Hati's left paw, immobilizing him. The wolf howled in pain as it tried to summon shadows to attack them from a range, but Irina used another holy light to blind the Moon Wolf. This allowed Xenovia to move in and cut off Hati's right paw, making it fall to the ground. Irina flew above the Moon Wolf and created a Ring of Holy Light from her fingertips. She threw the rings down, cutting the head of Hati Hroovinisoon clean off. 

Koneko, who was receiving help from Rossweisse finally began to go on the offensive against Fenrir. The Son of Loki tried to rip her apart with his massive claws, but Rossweisse blasted Fenrir away with multiple energy attacks that she conjured from her magic circles. With Fenrir distracted, Koneko was able to use her immense strength to pick up Fenrir and throw him into the air. She chased after the giant wolf in the sky and kicked him down to Rossweisse, who delivered a powerful beam attack that not even the Great Fenrir could go unscathed from. 

"I have an idea!" said Rosswiesse, "Follow my lead!" 

She summoned dozens of magic circles that surrounded Fenrir and blasted him repeatedly as Koneko began to build her power. She even transformed into her Shirone Mode to ensure that Fenrir would go down for good. The Son of Loki tried to swat the attacking magic circles away, but he was inaccurate due to the sheer amount of damage coming his way. Koneko charged two balls of energy in her hands and then when she was ready, fired them both as one big blast. Since Fenrir was too busy trying to deal with Rossweisse's attacks that he didn't even have time to prepare for Koneko's all-out attack. Her full power ripped through Fenrir, killing him for good. 

Skoll's Sunlight Blast was met with one of Sona's water serpents. Meanwhile, Akeno got a good hit in with her Holy Lightning, as Skoll was too busy dealing with Sona. 

"This is just like the good old days, isn't it Sona?" laughed Rias. 

"Those days couldn't be further behind..." smiled Sona as the pair blasted Skoll again. 

Skoll tried to put up a fight, but he couldn't even contend with the combined powers of Rias, Akeno, and Sona. While Akeno and Sona kept Skoll distracted with water and lightning, Rias completly destroyed the Sun Wolf with her destruction energy, leaving only Loki to take on his attackers. 

"Honestly, how annoying..." muttered Loki as he rubbed his temples, "I go through the trouble of reviving Fenrir and the others and they just break on me..." 

"Give it up, Loki!" yelled Rias, "It's over! You're outnumbered!" 

"Oh please!" laughed Loki, "Only one of you is strong enough to breach my barrier, and she's nowhere close to even rivaling me..."

(y/n) turned around to see a young girl with a gothic black dress and matching hair that flowed down to her waist. 

Despite her small frame, (y/n) almost tripped over himself when he saw her. 

"Y-You're... The Infinite Ouroboros Dragon!" (y/n) stuttered, "You're Ophis!" 

Ophis put a little smile on her face as she saw the Saiyan's panic. 

"I could help you, you know?" repeated Ophis in an emotionless voice. 

"Y-You wield the power of Infinity!" (y/n) said, trying to take a further step back into the door. 

Rias had told him once about the creature that wielded Infinity. The strongest dragon in the Universe was here in the form of a cute little girl. Despite this, (y/n) could help but quiver. 

Ophis took a small step forward and (y/n) extended his hand with a ki ball in it. 

"Take one step closer and you're history!" yelled (y/n), trying to muster up all the bravery he could. 

Ophis took another step forward and (y/n) fired, but it disappeared as soon it left (y/n)'s palms. Ophis sent out a small shockwave to (y/n). Upon feeling it, his knees buckled and he fell to the floor. 

"T-This is Infinity?!" said (y/n) in shock. 

Ophis was now right in front of him. Since (y/n) was on his knees, Ophis was just a head taller than he was. She reached out with her hands and placed them on his cheeks. He noticed that her hands were soft and warm as she rubbed his cheeks and moved his head around. If it were in any other situation, this probably would've been enjoyable. 

But not here. 

For the first time in his life, (y/n) was afraid.

"You were the talk of Hell 3 years ago when you joined up with Gremory," said Ophis, "But I'm not seeing anything special here..." 

Ophis took her hands off of (y/n) and stepped back. 

"You're stuck here. I can help with that." 

"W-What?" 

"I said, I can help with that?" 

"N-No, I heard you," fumbled (y/n), "But why would you want to help me?" 

"Because Rias and the others are going to die." 

"Die?!" yelled (y/n), standing up. 

"That's what I said..." 

She held out her hand. 

"Let's go. I'll take you to them." 

"I-If it's to save them..." 

____________________________________ 

Loki yawned as more attacks hit his barrier. Occasionally, he would have to move to dodged one of Rossweisse's attacks, but no real effort was exerted. 

"He's yawning?!" yelled Issei in frustration, "That bastard isn't even paying attention to us!"

"Then we make him pay attention to us!" growled Rias, "Everyone! Together!" 

Everyone below Loki fired their own individual energy blasts. Everyone's except for Rossweisse's hit Loki's barrier. Loki himself used his hand to block the Valkryie's attack like it was nothing. However, Loki was too busy fooling around that he didn't notice Rossweisse there right in front of him. She swung at him with one of her swords, forcing Loki to physically dodge. 

"Don't underestimate me!" yelled Rossweisse as she tried to stab Loki. For a moment, it seemed like she actually ran him through, but then his body disappeared. She felt a sharp pain in her stomach as she looked down to find his blood-red hand through her. 

"Just a trick..." whispered Loki as she dropped her down to the ground. 

Asia quickly began to work her magic as Rossweisse whimpered from the pain. 

"You bastard!" screamed Issei as he flew to attack Loki. His punch was met with Loki's barrier as the God rolled his eyes. 

"You never learn..." muttered Loki as he waved his hand. Hundreds of his Norse Magic Circle appeared and let out a rain of energy attacks that bombarded Issei and the others. Rias tried to protect everyone with a giant magic circle, but even she was having trouble against Loki's power. Loki's attack ended as soon as Asia was finished healing Rossweisse. 

"How is she?" asked Rias. 

"I-I'm fine..." said Rossweisse, "But... How are we going to beat him... How am I going to beat him?" 

"You can't," replied Loki from above, summoning a giant beam attack to kill the others. Before Loki's attack could hit, a blue beam of energy hit Loki's attack and canceled it out. 

"I wouldn't count us out just yet!" 

Rias looked behind her to see (y/n) there with Ophis at her side. 

"(y/n)!" said Xenovia as she wrapped her arms around him. 

"Are you okay?" asked (y/n) in a soft voice as he kissed her. 

"I'm fine... It's just that we may not be if we can't beat this guy..." 

"Put on a good show for me..." said Ophis as she disappeared. 

"I'm here to help!" said (y/n). 

"Unfortunately, you can't..." groaned Rossweisse, "He has a Godly Barrier that prevents any mortal from touching him." 

"But you can?" he asked. 

"Yes... But..." 

"Then follow me!" (y/n) said as he flew up to Loki.

Rossweisse followed and she took her place next to (y/n). 

"Ah, yes... The Saiyan!" exclaimed Loki, "Maybe you'll offer more of a challenge than you're pathetic friends." 

"Follow my lead!" said (y/n) to Rossweisse, "I know we may not be the best of friends, but lend me your power!"

"I-I'll try me best!" said his nervous teacher.
