Chapter 19 - tetragrammaton

After finishing his observation over his new ability, Issei gaze shifted focus on the armor he wore when trying the true maou powers. It was radiating an absurd amount energy unlike the first time it appeared.

'So its storing demonic energy in the surrounding? This does make it interesting."

The armor was absorbing the surrounding energy and condensing it into demonic energy which meant Issei had large reservoir if he were to run out.

'I do dislike the how it looked.'

Issei imagine the armor to appeared into something else and it began to morph into an different appearance. It was black in color with red lining covering his whole body with bits and pieces reaching his cheek. Issei eyes had a visor but did his obstruct his vision.

'What just happened!?"

[It seem it can change form but I uncertain what extend?]

'Let me try changing it again."

Issei tried changing form and change into anything but it depended how it looked. The demonic energy disappeared when morph into civilian clothes but it needed to be similar to its original form.

"Crimsyn can you help me?"

"Sure Aniki?"

"Try attacking me."

She didn't hesitated and created a fireball towards Issei who remain stoic until the attack him it instantly vanish into air. Issei notice his new armor was able to cancel any attack be it physical or magical.

'It disrupt the flow of energy….won't this defy power?'

The armor was similar to sacred gear canceler but rather than only sacred gears it cancel anything it came to contact even inertia as Issei felt to no resistances.

"I want to see its durability let's spar."

"That's what I like to hear, Aniki!"

Both of them took a stances then in blink of an eye appear in front of each other. Issei law of physics was being canceled by the armor as he clench his fist and punch Crimsyn with full forces. This cause a hurricane of wind that sent the nearby tree flying.

It was a good thing that they were in unpopulated area and Issei had made sure to erect a barrier strong enough to take their sparring session. The barrier was to avoid ant unwanted guest to know their location.

Issei punches didn't cause a backlash being canceled by the armor. The law of equal opposing force didn't apply when paired with the armor.

"Your spacing out, Aniki!"

Crimson threw a powerful right hook to the side that sends Issei flying through the mountain nearby creating a human-size crater. She only used ten percent of her power enabling Issei to survive.

Smoke and dusk were blocking her opponent but with tremendous speed, a young with short white hair with black sclera, and crimson red pupils grinned maniacally. He was releasing an absurd amount of demonic energy that began to manifest itself.

"You seem to have gain a power up, Aniki!?"

"Yeah I guess. It seem our spar is helping the fusion progress of faster."

"Oh how about take this up a notch, Aniki!?"

Their power increase reaching C ranked super class but Issei body couldn't last long as the enormous amount of demonic energy being generated by his bloodline was poisoning his body.

'Shit I need to find a way to balance it out.'

The demonic energy was like the yin which needed the yang in order to main itself. Issei then tried using his divine energy to balance out his demonic energy which causes twelve black and white wings.

[ISSEI YOU IDIOT!!!]

"AAAARRRGHH!!!!"

Issei felt his whole body disintegrating with his flesh melting from the influx of chaotic energy. He tried something that needed precise control that if anyone were to try it then they would instantly die.

Asia who stopped her own training heard Issei screamed in pain and quickly ran to where he was.

"That's extremely careless, Aniki."

Crimsyn who unfazed by Issei raging power that was reaching B-ranked middle God class from energy quickly used her power over dream to dispelled the energy knocking out Issei. Before he could fall, Crimsyn caught him and slowly descended where Asia waiting who gasped in shock and quickly healed him.

"He surely doesn't change. Always careless in doing stupid stuff."

_______________________________

Issei got up from where he laying and quickly scanned his surroundings and found himself in a void of nothingness.

(For someone gifted by tetragrammaton you surely stupid. Well it's to be expected by being a child of that fool.)

Issei heard a mocking voice with an unknown gender. He tried turning around but only abyss of darkness could be seen as far as eye could see.

"Who are you!? Show yourself!"

(Nah I don't want to show myself this early but you can call me…let me see….Enoch would suffice.)

"Okay Enoch why did you brought me here? Don't tell me you only summon me to just insult me?"

(Hahaha of course not. I'm just warning you if you tried doing what you did then…it would be disappointing for you to die so early.)

"Yeah I know I'm not stupid enough to do it again with training."

(Oh right tetragrammaton told me that twelve of the dark apostle would soon arrive in this timeline.)

"What!!!"

Issei was horrified from hearing the mysterious voice. The twelve apostle that each had the book of Necronomicon that allowed them to used power of the outer becoming equal to a S ranked low primordial God.

Only the top ten strongest God could dream of fighting them equally. However, it would never result in the death of the apostle.

(Jeez relax there power would be at most a S-ranked superclass and they limited in using their forbidden arts when tetragrammaton put seal in this place.)

"That doesn't make it less troubling."

(Hahaha good luck with that kid. I don't what tetragrammaton is planning why I'm with you but it would surely fun to see.)

Issei was distress gaining new information about the future but calmed down knowing panicking won't give anything good.

"When will they arrive?"

(Don't know but it won't be more than five years.)

Issei nodded as it was enough time for him to gain at least Low God class in few months.

(Well it's time to wake up hope you entertain me and don't always train cause it's boring.)

"Wai-!!"

Issei eyes gradually opened seeing the blue sky then turn to see Asia healing him while having a tears on her eyes which he tried to clean that cause her to looked at him.

"Your awake!!"

Asia gave him a tight hug which cause him to wince in pained but hide it considering the interaction as payment for making her cry. He rubbed her back while tears fell on her face.

"D-Don't ever do that again."

"You're awake, Aniki?"

"Issei are you alright?"

"Yeah I'm sorry, Asia for making you worried. Thanks to you I'm all healed up."

Issei gave wide grinned while trying to stand up. He didn't know but his eyes had form crimson red crossed that quickly vanish as it came.

[Issei that was truly careless thing to do! Even compare to absorbing the divine divider this is beyond stupid. Your lucky that this period blood-.]

"Hey!!"

[-Was able to used her power to save you. Even compare to the old great main and Seraph it was an enormous amount of demonic and angelic energy and because you tried fusing them, it causes a backlash similar to extremely cold object being met with extreme heat.]

Ignoring Great red(crimsyn) complaint Irene explain to Issei. Even with his armor capable of cancelling any energy was overwhelming by his power. The armor was still in it's infancy stage and would grown stronger along with the user.

[Additionally, we need to go I'm sure the other faction are in there way to locate us.]

With that they immediately return home before the other faction leader came investigating the sources of a massive divine and demonic energy. They only met with residual demonic energy and divine that led to nothing.

ORC building

Issei quietly entered the room being met with Rias reading the manga. She was too focus on the book for her to notice him. He grinned looking around seeing they were alone slowly approach her.

"Boo!"

"EEEHHH!!"

Rias scream in surprised dropping the manga and turn to see chuckling that made her blush realizing she was too concentrated in noticing issei.

"I'm surprise buchou like the manga."

Issei picked up the manga then place it to the table while staring at Rias. She quickly compose herself trying to hide her embarrassment.

"You surprise me issei."

"Hahaha sorry I couldn't it since your too focus on it which I found kind of cute."

"C-Cute? You found me reading manga cute?"

"Yeah it meant that your just like normal girl."

Issei sincerely smiled that made Rias entice by his expression that her heart beat. His word held a special meaning to her since she always wanted to be seen as 'Rias' and not 'Rias Gremory.' She wanted to be treated normally and gain the eyes of the man who did not contain the same lust as the other devil especially her fiancée.
