Weakness

"Wanwan is more troublesome than Dad. You would die most of the time if you were bitten by his fangs. But he has a weakness. The magic-chain Gleipnir created by the Dwarves can capture him. You can seal his movement with that." Midgardsormr explained. Azazel sighed.

" We have already checked that. But from the reports from the North, the Gleipnir didn't work. That's why I thought about getting another method from you. " Azazel replied. Issei suddenly had an idea.

" Wait, guys! I think I have the perfect thing to deal with Fenrir. " Issei shouted out loud, surprising everyone. Issei disappeared using Soru and appeared a second later holding Great Red's giant fang.

Midgardsormr blinked seeing the fang. "A fang?" Midgardsormr muttered, feeling confused.

"It's Great Red's fang. I punched it out of him and took it home as a souvenir. It's hard as a motherfucker, my Hakai could only chip it a little." Issei explained. Midgardsormr hummed.

" Well, I think you've already found your solution. Just one more thing?" Midgardsormr looked at Issei.

" How do you plan on using it? " He asked him. Issei smirked.

" Beat him until he doesn't move anymore " Issei replied bluntly. Midgardsormr chuckled.

" Good idea. Well, I'm off now. Wake me up when something exciting happens. Bye now." Midgardsormr nodded at them before the vision turned off completely, and he had completely disappeared.

"Well. That does it for the countermeasure. Now we just have to get Saji up to snuff for the fight." Azazel grinned at Saji who shivered. Tannin walked up to him.

"Right now, you don't deserve to have Vritra's powers. But us two will whip you into something else. Hehehehe..... Issei survived my training. You can to if you're determined enough. C'mon, let's go. " Tannin chuckled. Azazel patted Saji's back. Saji was crying.

" Uuuuuuu..... This is it. I'm bouta die....."

The time of battle. The sun has already come down, and it's already night. The Gremory Group, Irina, Azazel and Issei were on top of a high rated hotel building in the suburbs which is the place where the meeting of Odin and the Japanese Gods will be held.

They were standing very high up so the wind breeze was violent.

On the rooftop of the surrounding buildings, the members of the Sitri group are positioned there and they are on standby. Saji was still back in the Underworld doing Tannin's special training.

Azazel had to be the middleman for the meeting so he is staying besides Odin In replacement of him who can't participate in this battle, Baraqiel is on standby on the roof with them. Rossweisse is also participating in this battle so she is wearing armour while being on standby.

And very high up the sky, Tannin is up there. He had a spell cast on him where normal humans won't be able to see him. Vali and her team are waiting for the battle, a bit further away from them.

"It's started." Rias muttered as she looked at her watch. The meeting started, what's left was to wait for Loki to come.

The sky above the hotel started to become distorted, and a big hole was created. The ones who appeared from it were Loki and Fenrir.

Sona Immediately activated the magic circle to transport everyone, Loki and Fenrir to the battlefield. Loki knew what was happening. He just smirked and didn't retaliate.

They arrived somewhere else. It was a spacious field and was filled with rocks. The battlefield was supposed to be an abandoned ancient mine.

"Boost!!!"

Issei didn't waste any time and appeared in front of Loki immediately. He palmed Loki's face violently and threw Loki up to the air.

"Juggernaut Over Drive!!!!"

Vali appeared in front of Loki in her Empireo Juggernaut Overdrive form. She slammed her fist into his gut, making Loki grunt a little.

"Divide!!!"

Loki's power was halved now. But he was still as powerful as ever. Issei appeared in front of Loki.

"Boost!!!"

"Divergent Fist!!!!"

*BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMM!!!!!!*

Loki spat out a large amount of blood and flew back. He felt his insides exploding and spat out even more blood.

Fenrir tried to cleave Vali in half with his fangs but Issei interrupted the attack by tackling Fenrir midair.

Fenrir crashed into the ground. Issei looked at him with a sneer.

"Boost!!!"

Issei smirked crazily. Suddenly, two wolves appeared behind him, in the middle of trying to cleave Issei in half.

They were Sköll and Hati and they were the sons of the God-Devouring Wolf, Fenrir, after their grandfather Loki; the Evil Norse God of Mischief, turned an unnamed Jötunn woman into a wolf.

Both Sköll, and Hati have notable differences between the wolves with Sköll having far darker grey fur.

Hati, on the other hand, has greyish blue fur similar to that of Fenrir's if not slightly darker, but both of them still possess the same two golden horns from their shoulders.

The two wolves tried to kill Issei. Issei saw it coming from a mile away. Suddenly, Vali jumped in front of Sköll and Hati and clotheslined them.

"Divide!!!"

Vali halved the Hati's power. Issei appeared beside Sköll and halved his power with the Dividing Gear.

Issei threw them up to the air. He pointed at them and charged up a crimson colored ball.

"Boost!!!"

Issei fired the small ball at them. The small flew rapidly and arrived besides the flying wolves.

"Hakai!!!"

*BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMMMMMMMMMMMMM!!!!!!!!*

The ball exploded midair, engulfing Sköll and Hati. Loki stared in horror as he saw Sköll's wolf head landing in front of him.

Fenrir growled angrily at the two Heavenly Dragons. He was enraged. Issei didn't care about what he was feeling, nor did Vali.

Fenrir howled, mourning his children's quick deaths. Issei interrupted his howling by appearing in front of him.

"BLACK FLASH!!!!!!"

*BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMMMMMMMMMMMMM!!!!!!!!*

Fenrir screamed in agony as he was dropkicked on his back. He landed on the ground and had blood endlessly flowing out of his mouth as Issei stood above his head.

Issei grinned broadly as he took out a giant tooth. He grabbed it with both hands and raised it up high.

"Boost!!!"

*BAAM!!!!*

Issei slammed down the fang into Fenrir's skull. Fenrir howled in agony as the fang pierced his skin like butter. Issei raised it up high and brought the fang down again.

"AGGGH!!!!!" Issei growled as the fang pierced through Fenrir's skull again, splashing blood onto his face.

Issei kept screaming in anger as he brutalized Fenrir who couldn't do anything about it because he was too in pain to even react properly.

The fang was painted in bright red blood. Issei kept going, not stopping at all. Fenrir had already stopped moving but Issei didn't care. This wolf was about to kill Rias that day, he couldn't let it slide.

The brain fluid was already leaking out of Fenrir's skull which was already dust. Issei stood up straight and looked at the bloodied fang in his hands. He grinned and faced the sky.

"WRRRRRRRRRRRRRRRRRRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAGGGGGGGGGGHHHHHHHHHHHHH!!!!!!!!!!"

Issei roared menacingly, showing off his victory over Fenrir. The roar sent everyone skidding back with the shockwaves it created. Issei stopped roaring and chuckled to himself.

He stored it back into the Boosted Gear's infinite inventory and stepped off the wolf. He looked at Fenrir and looked at Rias who was holding in her breath while watching Issei brutalizing Fenrir.

"Burn him Rias. I'm going to deal with Loki...
