In High School Dxd With Powers Of Nanatsu No Taizai

'This has been harder than I thought,' Leo thought.

What was before the legion of devils had disappeared, a multitude of corpses piled up in the area.

Sighing, Leo felt better, although he was not used to killing he knew he had to do it and yet he felt nothing.

To test his skills, Leo did not want to use his magic much and decided to focus on close combat but to his disappointment, the devils were too weak and that he had not even used his mark

'Well, at least I know that all that training with Serafall served something, although it would be good to improve my hand-to-hand combat skills a little more,' Leo thought to himself.

With the horde of devils exterminated, the group quickly arrived where the hostages were.

In the place where the hostages were located was a rustic building two stories high, with the nȧkėd eye you could see several formations drawn in its structure.

"We kill enough and still more come" Leo muttered as he looked at the sky.

"Toshiko, Nara. you rescue the hostages,

we will take care of the devils that come I doubt they will give up easily "Gacus ordered.

Nodding towards Gacus, they entered the building.

"We have to defend the area until they have evacuated the hostages" With enemy reinforcements on the way, Gacus decided to let Toshiko and Nara evacuate the hostages.

"Don't you think it's too reckless to let them go alone?" Even knowing their abilities, Leo couldn't help doubting since they couldn't use all their power due to the interference of the barrier, although it wasn't much.

"Relax, they have been in this kind of situation before so they are used to it, we just have to worry about what we have in front of us," Gacus replied.

"How is your condition, can you continue?" Gacus asked.

Smiling satisfied at his response, Gacus can't help feeling curious by Leo. His attack power was great, although his melee combat skills were not polished enough, he was still quite skilled. Moreover, his abilities were quite lethal either the snow or that black aura, Gacus was not sure of leaving unharmed.

"There is no doubt that it is quite powerful, as expected of someone recommended by Leviathan-sama," Gacus thought.

At first Gacus was not sure of the success of the mission and adding the fact that the rescue of the hostages was of vital importance could not help feeling insecure, his team was originally made up of Toshiko and Nara but at the last moment they included Yasuo that He was a newly promoted soldier and Leo was a taciturn hooded man. For a moment he came to think, is this a joke? but everything turned out better than I expected, Yasuo turned out to be quite determined and Leo was like a reaper once he reached the battlefield.

Spreading his wings, Gacus flew over the building.

"They are worse than rats" Gruño Gacus.

compared to before, there were even more so many devils that filled the horizon.

"They are only cannon fodder, only a few are worth it" Leo replied.

'For now, it's not necessary to use my brand,' Leo thought to himself.

Forming two wings, Leo headed to Gacus.

"Gacus, get ready" Leo shouted.

~ Dark snow ~

As soon as the snowflakes began to fall, the devils did not panic, everyone took distance from their partners taking without damaging

their formation,

Unlike before, they had learned how to avoid their attack as anyone who came into contact with a snowflake was abandoned to their fate.

Once they had time to reorganize themselves, the devils created numerous magical circles that filled the entire sky. Seeing this, Leo couldn't help cursing, he had just dealt with a horde of devils and now he was going to be bombed again.

All the attacks pointed towards the duo and without Toshiko and Nara supporting them, they had to deal with the enemies themselves.

Positioning himself in front of the attacks, Leo transformed his arm into a sword and pointed it in the direction of the attacks.

~ Full Counter ~

~ SLASH ~

With a flash, a torrent of magical energy shot toward the horde of devils.

~ BANG! ~

The attack hitting the horde of devils except for some devils who managed to avoid it and created barriers to protect oneself.

'What is that…? ¡It's only been for a moment and all the attacks disappeared!." Gacus thought, his eyes widened in shock.

Of course, Gacus I had seen several strange techniques from devils but had never heard of any technique like the one Leo used.

Remaining still in place, Leo watched the horde of devils to catch any suspicious movement.

'What are they supposed to do?' Leo thought to himself.

Since they had entered the barrier, everything was too strange, the enemies were weak and the only problem was their numbers, they had already finished with a lot of devils and yet Yasuo had not returned, other than that, everything was too easy.

Leo thought. When he realized that this meant that as long as the enemy had the hostages Sirzechs and Serafall they couldn't do anything. But what if they weren't preventing them from taking them?

'No wonder, they are just trying to save time. They know that they cannot keep the hostages and without these Sirzechs and Serafall, they will go with everything so they are only trying to gain time to escape so once the hostages are free they will start the real battle.' Leo thought

"I refuse to get out of here until I have found someone to fight with," Leo thought as he headed for the horde of devils. He wanted to put all his skills into practice or he would be trained so hard for anything.

Entering the front line, Leo quickly avoided all incoming attacks while stretching his arm Shattering a nearby devil.

By quickly transforming his arm into a claw, Leo used it to break the barriers with which some devils were protecting themselves.

The barriers were nothing more than air, as he easily shattered them. Flying forward, Leo used his wings sweeping the enemies.

Sending flying to the devils, Leo didn't waste much time while continuing his attack without giving them the having chance to recover.

Within a space isolated from the barrier, Sirzechs and Serafall was watching Leo on some kind of television

"Soon ... and when will you tell me where you got this boy?" Sirzechs asked as she looked at the screen.

"Would you believe me if I told you that I found it by chance?" Serafall asked with a smile.

"You're telling me that you found someone who can slaughter a legion of Mid-class devils like nothing. By chance?" Sirzechs looked at Serafall with doubt.

"Hehehehe, Leo-chan has many secrets and our relationship is to give and take, in exchange for teaching he magic, he agreed to come. Even so, in all my life I had never seen someone with those skills, and you? "

"Nor have I seen anyone like him, much less someone with that black substance," Sirzechs replied with a sigh.

"Dark matter, it seems, is very powerful. I don't know its characteristics by adding his great control over it more its talent for magic and its physical abilities make it terrifying." Serafall added with a frown.

"More powerful than the power of destruction?"

"Eh ..." Serafall exclaimed in amazement.

"I do not know. As I have told you, it has never let me analyze it more closely so I cannot ȧssure you anything but in my opinion, I do not believe I as powerful as with the power of destruction."Serafall replied with a sigh, as Leo had not allowed him interacting with dark matter, she didn't know very well what his composition was made of, she only knew that I could repel magic in a certain amount, more what I had seen Leo use in this battle.

"We only have to wait to know what he is capable of. Are you still going to take him to the underworld anyway? "Asked Sirzechs with some doubt.

"I have promised, and soon the ceremony will take place to give the evil pieces and I hope that Sona manages to return it to one of her evil pieces." Serafall smiled expectantly.

"I would also like him to be one of Rias evil pieces" Sirzechs replied with a smile

"Come on Sirzechs-chan, Leo-chan continues to refuse to become one of my evil pieces but that does not prevent Sona from having a chance and if Rias-chan can make him one of her evil pieces I will not object. Besides, hadn't you already got two possible candidates? if I'm not mistaken." Serafall replied calmly.

"Yes, the girl from the Himejima clan is currently with Rias and the Nekomata will be with her once we finish here, as I promised her sister. So once Rias performs her ceremony she will make them part of her evil pieces."He replied.

"Hehehe… we'll see which one of them is capable of achieving it. For now, it is better to end what we have in hand."Responding. Serafall pointed her finger towards the transmission, in this one could see Leo killing the devils, shaking her finger, the transmission changed and showed Toshiko and Nara coming out with the hostages.

"The hostages are now free. It's time to get out of here." Finishing speaking, Serafall created a magic circle and lashed out at the barrier.

BOOM!

As if it were made of glass, the barrier collapsed after the attack. Without stopping for a moment, Serafall and Sirzechs spread their wings and coming out of the barrie
