I don't own Highschool DxD, all credits to its creators.
"Nee-sama, why?" Koneko asked Kuroka.
"Ophis and Vali will gladly accept you, nya. You have the same power as I running through your veins." Kuroka said.
"I'm part of Rias Gremory's family." Koneko said.
"We're not handing her over to you!" Issei said.
"I'll take her by force if I have to, nya." Kuroka said.
(At the gathering)
"Not so fast!" A voice said coming out of a magic circle. He has the appearance of a handsome man with eyes similar to that of a delinquent's. He has light blue hair that floats behind him with two small shoulder length bangs. Loki also has 3 blue jewels on his forehead and yellow earrings.
"Foolish man." Odin said.
"I am the Norse god, Loki!" Loki said, identifying himself.
"Now this is rare." Azazel said.
"Loki, though you are a norse god you have no right to cause mischief here." Sirzechs said.
"Seeing our father mingling with other mythologies brings me intolerable pain." Loki said.
"Loki, if you return to Valhalla now I will forgive you." Odin said.
"Forgive me Don't joke around old man. If he allies us with other mythologies, we will be unable to achieve Ragnarok!" Loki said.
"Why would you want that?!" Serafall shouted.
"You're a part of the Chaos Brigade, aren't you?" Azazel asked.
"Yes, I have partnered with them. But this is my own will! Come forth my son!" Loki said as he opened a magic circle and out came a giant wolf with ash gray fur, standing at about 10 meters tall.
(Forest)
"Issei! Koneko! we need to hurry back!" Rias said. But then a barrier created by Kuroka surrounded them.
"I Created a barrier over this entire forest and shut us in, nya." Kuroka said. "Anyway, are you going to hand me my sister now? If you don't then I'm going to have to kill you, nya." Kuroka said.
"Nee-sama, I will go to you." Koneko said.
"What are you saying?!" Rias said.
"So please let them go." Koneko said.
"Koneko! You are a servant and a member of my household! I will not allow you to do what you want!" Rias said.
"I know my onee-sama's power more than anyone." Koneko said, shaking.
"Don't worry, I will protect you." Rias said while hugging Koneko.
"I understand Shirone's power better than you. Come here, Shirone. I'll make you top-class in the sage arts." Kuroka said.
"No. I don't need power like that. I don't need power that brings misfortune to others." Koneko said with tears forming in her eyes.
"Kuroka. In your little episode of power, you left a scar on her that will never disappear. When you left after killing your master, this girl saw hell. When I first met her she didn't have any feelings left inside. Koneko was betrayed by her only family. She had no one to turn to and the other devils hated her, to the point she was almost disposed of. This girl has seen many painful things." Rias said.
"Rias….." Koneko said.
"And that's why I will show many wonderful things to her." Rias said. Then she noticed Issei's face expression.
"Hmm, Rias you're not wrong about what Koneko has been through, in fact I very much admire how you care for her. However Kuroka seems to have a different story to how people see what really happened." Issei said, catching Rias and Kuroka's attention.
"Oh?" Kuroka said.
"I can see it. Your eyes, your breathing, your heart beat. It looks like they're all telling a different story, Rias, I'm not justifying her actions but it seems like there may be some miscommunication here between Kuroka and the devils." Issei explained to everyone's surprise.
"Well he's onto something there which I didn't think I would have the chance to explain. But still if you wont give me my sister I think I'll just take her." kuroka said as she used magic. As both Koneko and Rias fell down.
"Are you ok?!" Issei asked, concerned.
"It works so well on devils and spirits, but you're a dragon so I didn't know what to expect." Kuroka said.
"Why? Your own sister is in there you know?" Issei said.
"Don't worry I've weakened the poison so they don't die immediately. But I'm still taking my sister with me, you too cutie." Kuroka said.
(At the gathering)
The giant wolf was attacking everyone then it was about to attack Akeno, then I was stopped by Baraqiel who used lightning to make it back off.
"You fool." Loki said. Then he and his pet were enveloped by a green light then they were teleported away by Ajuka.
(Forest)
Rias was attacking Kuroka but she was missing each shot.
"Nice attack, but it's no use!" Kuroka said. Then she went to attack Issei who without effort smacked away her attack. "What?" Kuroka said.
"As potent as your attacks are, you can't do any damage to me." Issei said.
"But Issei-senpai, why don't you go up there and end it." Koneko asked.
"Remember what happened after I caught you spying on me?" Issei asked with an embarrassed face while Koneko blushed wildly.
"Oh? Do tell." Kuroka said, also catching Rias' attention.
"So you know that phase that prepares you for mating season?" Issei asked.
"Oh I see now, but luckily you still smell like a virgin so I still get to take it, nya!" Kuroka said, getting a flushed face out of Issei.
"Oh, so he's still a virgin thank goodness, I won't blame you this time Issei since this is natural." Rias said while blushing as well.
"Anyway, time to end this." Issei said. He then shot multiple energy blasts at Kuroka, but just as they were about to hit her they stopped in front of her.
"Huh?" Kuroka said. Then the energy balls exploded breaking the barrier she made and also launching her in the air. Then a beaten up Bikou caught her while he was flying on a cloud. "What's the big Idea?! It's not over yet!" Kuroka said to bikou.
"Did you not notice?" Bikou said.
"Loki's presence is gone?" Kuroka said.
"Yes, but unfortunately playtime is over, we have to go." Bikou said.

(Gathering hall)
Everyone had left but Rias, Issei and Koneko were at the hall while Rias was explaining everything to Sirzechs.
"I see. His accomplices from the Chaos Brigade were…" Sirzechs said.
"Bikou and Kuroka." Rias answered.
"And Koneko. Is she alright?" Sirzechs asked.
"She received a shock but she's fine now thanks to Issei." Rias said proudly.
"Looks like I was right to give her to you. You've grown wonderfully as a master of your household, Rias." Sirzechs said.
(Scene skip)
Sirzechs, Odin and others were at a table sitting down.
"Ajuka teleported Loki and Fenrir to a far off land, but this is only a temporary solution." Sirzechs said.
"Yes, I'm sure that he will attack again." Michael said. Then Odin stood up.
"As the leader of the Norse, I take full responsibility." Odin said.
"We need to defeat Loki which is why I've devised a plan. But Ajuka, who teleported Loki, can only keep Loki at bay for about a day." Azazel said.
"Just one day?" Rias said.
"If Loki recovers and attacks, we'll have to fight him head on. And if that happens Loki's Ragnarok will begin." Azazel said.
"Onii-sama. No, let me see Sirzechs." Rias said.
"So you want to try and slow him down?" Sirzechs asked.
"I can only send about ten people at a time to Loki." Ajuka said.
"I can send more if that's fine with you." Issei said.
"Yes, it shall be." Ajuka replied.
'Seems that others want to join as well." Serafall said. Then the door opened revealing Sona, Tsubaki and Saji.
"Three members of the Stiri family wish to volunteer." Sona said.
"Very well, with that all the people from each side have been chosen." Azazel said.
"From our side." Michael said while stepping aside, revealing Xenovia and Irina.
"Leave it to us!" Xenovia said.
"And from our side." Odin said while stepping aside. Revealing a beautiful young woman with long, straight silver hair and aqua-colored eyes who appears to be in her late teens.
"Please buy us some time." Sirzechs said.
Outside
(Issei's magic circle)
"It saddens me that we won't be together. But for your safety I'm leaving you here" Rias told Asia and Gasper.
"Alright, Issei-san, make sure to come back." Asia said.
"That's right senpai!" Gasper added.
"Don't worry, you know I will!" Issei said.
"I enjoy our visits Asia." Irina said.
"So do I." Xenovia said.
"I apologize for the late introduction. I am Rossweisse of the Norse mythology, a valkyrie." The girl now known as Rossweisse said, she was now also in a set of Valkyrie armor, which consists of a white breastplate with gold and pale blue accents and matching, fingerless gauntlets, boots, hip guards, and wing-shaped hair clips. She also wears a black leotard underneath her breastplate, black thigh-high stockings, and a pale blue cloth wrapped underneath her hip guards, all of which are clad with pink lacing along with her hair clips.
"Don't be rash." Sirzechs said.
"Yes." Rias said.
"Issei-senpai." Koneko said, grabbing Issei's attention. "Give me courage." Koneko said.
"Don't worry." Issei said, patting Koneko's head. "No matter what happens you will be fine because I will protect you." Issei said, causing Koneko and Rias to smile. "Alright, I shall begin the teleportation." Issei said, then the group was enveloped by a green light. Then they arrived at the outlands where Loki was trapped. Then suddenly the barrier the Ajuka created broke with Loki and Fenrir coming out.
"Beelzebub! Playing such dirty tricks!" Loki said in frustration.
Loki! Baring your fangs at our great father is unforgivable! You should voice your opinion through the proper channels!" Rossweisse said.
"The Valkyrie that accompanies Odin. I hear you are talented, but your power is far from a god's." Loki said.
"You refuse to listen to reason." Rossweisse said.
"You all are much too weak for the opening act of Ragnarok." Loki said. Then he blasted several beams revealing Fenrir's children. Then he opened a portal in the sky and down came a dragon which Issei recognized all too well.
"One of the five great dragon kings. Well Loki, you look like you were prepared. However, what happens next is not in your hands." Issei said.
"Oh and what will you do, Red dragon emperor?" Loki said.
"Hey Tiamat." Issei called out to his familiar through a mental link.
"Oh hello there Issei-kun! I was just doing your laundry." Tiamat said.
"I need you to come here. There is someone I want you to fight." Issei said to Tiamat.
"Oh that sounds interesting. Summon me and I'll be ready." Tiamat said.
"Alright then!" Issei said out loud. Just then Issei opened up a green portal which out came Tiamat in her dragon form to Loki's shock.
"What?!" Loki said.
"You didn't expect that, did you, Loki? Guys, I'll deal with Fenrir. You take care of the other two, and Saji use your absorption line to hold back Loki." Issei said to everyone's agreement. Fenrir changed at Issei who effortlessly dodged the assault. Then Issei charged up an eraser cannon in his hand then hit Fenrir with it, then the wolf was being propelled to another part of the outlands away from the main battle with Issei flying after it. Xenovia, Irina, Kiba and Koneko where dealing with one of the two other wolves, Koneko finally pulled out her cat ears and tail and used her senjutsu on the wolf, while Kiba and Xenovia followed with a frontal attack on it Kiba using sword birth and Xenovia using Durandal's power, then Irina came in and used a ring of light to trap it while Rossweisse came in and rapidly blasted the wolf. Now with Tiamat facing Miðgarðsormr Tiamat being the superior dragon king was easily thrashing the sleeping dragon. And now with Rias, Sona, Akeno and Tsubaki, they were facing the other wolf head on with nice progress, then Akeno finally accepting herself as a fallen angel uses her holy lightning. Now with Loki he was facing Saji as he finally caught him with his abrobstion line, Loki tried to break out but he could not, then Saji revealed that he has all the Vritra sacred gears thanks to Azazel. But unfortunately Loki broke out while incapacitating Saji. Then out of nowhere a paralyzed Fenrir landed back onto the battlefield with Issei just now arriving back.
"Loki, you might as well give up this fight you have no chance of winning." Issei said.
"I beg to differ, you may have defeated my son but you cant defeat me!" Loki said as he used a wide-spread attack on everyone on the battlefield. But then Issei appeared right in front of Loki and then hit him with an eraser cannon in his hand knocking the evil god to the ground knocking him out.
He just tried to curse us as a last ditch effort, but I repealed it before he did." Issei said.
"So anyway what do we do now that it's over?" A healed saji asked.
"You done Tiamat?" Issei asked.
"Oh yeah, but it turns out it was fake, the real one wouldn't die so easily." Tiamat said.
"Well it seems like you no longer need any reinforcements. Issei Hyoudou, one day I'd like to fight against you on any terms." Sairaorg said now arrived.
"He won't lose when that happens." Rias said.
"Sounds fun! Also someone took Fenrir." Issei said. "So what should we do with Loki?" Issei asked.
"We'll take care of him." Rossweisse said.
That's it for now. See ya! But first….
Attacks Issei used.
Eraser blow
Gigantic slam(On Fenrir away from field)
