Chapter 99 - Won the war yet lost the battle

Within the heaven, all of the administrators who had foreseen the outcome had quickly acted and activated the powerful berried preventing the outer gods in further reaching their world or any invader that had ill intent to their world.

The tower that's Issei built began to glowed then shut a pillar of light in the sky where everyone saw them then the sky was enveloped in thick And immensely powerful barrier whose capable of killing anything. The administration had been the task by their father and helped in creating the tower. Now it was finally finish, the outer gods would need an absurd amount of time in order to return which would be never.

Rias and the others were crying their hearts out that Issei was killed in the blast. Sirzechs and the others comforted them trying to eased their pain but knew it was impossible. It was then when they saw the barrier to be activate surprising everyone and calming their mind. Afterward, all that was connect with Issei were inform by Sariel was still alive and would return but doesn't know when. They couldn't believed but he informed them about trying to senses him.

If he dies then the sacred gear and the activation of the tower wouldn't work. Additionally, the four of them are link to Issei more ways than one that if he die then they two cease to exist. Their purpose was to serve and help Issei in the first wave of their battle with the outer gods. It was then a astral projection of Issei appears before them. They all tried to run up to him only pass through him.

"Hehehe don't try hugging me I'm just lingering astral projection message that I made in each of your rings."

They all looked at their fingers looking at the beautiful ring that had their own unique design from each of them like ravel had beautiful phoenix on it or Ingvild with a leviathan. Everyone stared at Issei giving warm smile to them.

"Issei where are you!? Tell us will to rescue you!"(Ravel)

"Don't bother if I have to guess I was launch in far region of another world because of the fabric reality was affected. I don't know when I'll return but I promised I'll here in one pieces, just all of you wait then we can have how many children you want."

Astral Issei explained as their fight would resulted in him passing through over countless worlds from how much their power had disrupted reality. Their eyes went wide as the projection slowly fading away into pparticle.

"Wait Issei don't go! We hadn't even gotten to the cosplay convention!"(Rias)

"You promised we'd go in tepes along with Gasper-chan!"(Valerie)

"Valerie…"(Gasper)

The astral projection wince in pained seeing them tried their best to let him stay but he was nothing more than messenger that would soon fade. He clench his heart as tears began to flow down his cheek.

"…I'm sorry! I wanted to say so much that I'm willing to do anything to stay but I needed to pass through rift of worlds to save all of you. Please be patience and wait for me."

Issei could had easily defeated Nyarlathotep vessel if he wasn't busy trying to control his power output and his opponent to avoid it being affected his lovers. He sacrifice a larger amount of power to protect all of them. Even after countless years his path had never wavered.

Hearing his final word they intently watch him slowly faded and was determined to wait even how long it takes. They were going to protect the world that Issei sacrifices and spread his heroic deeds. Every faction would celebrate the day of the Draconic Deus.

_______________________________

Floating in the vast sea of the dimensional rift where tunnel worlds are located. It was placed with the complicated and constant flux of change that even how fast the perception of someone wouldn't be able to comprehend a single image of the place.

Within it was the floating naked body of a young man with long pure white hair and a body that shredded muscle but not bulky that if he wore clothe then many would think he was woman. His body had countless scars and newly acquire wounds that continuously bleed despite it constantly healing.

He was of course Issei who was busily controlling the fluctuating energy inside his body but couldn't fully control and was gritting his teeth from the pain. He still conscious but unaware of his surroundings and only knew their were two individuals arriving.

"He won't survive if this keeps up, Akasha."

"Why are you in a rush when your embodiment of time, Epoch!?"

"Aren't a bit of worried when you Son-in-law is in danger?"

"Don't be such a baby and just do it."

It was then Issei felt his control over the fluctuating energy had become a lot easier then finally disappeared calming down his body. He tried opening his eyes found that it was closed shut with only his other sense working.

"We know you're conscious but don't try looked at us when your still this weak. I am impressed you manage to reach Extradimensional scale of power but too bad your body couldn't handle it even if our daughters power inside of you."(Epoch)

'Who are you and why did you call me your son-in-law!?'

"Well it wouldn't hurt if we tell you our names. I am Akasha, Embodiment of Space and Infinity."

"I am Epoch, Embodiment of Time and eternity. We are the parent of Ophis."

[A/N: this idea came from DxD Mightverse. Most my inspiration came from them so hope you check it out]

Issei was bewildered from hearing their names. They are not gods but the literal embodiment of this concepts. Their power are beyond his current mind could handle therefore this gods are constantly pressing their power around him. He believed them knowing that lying to him wouldn't benefit them the slightest.

'I see. Anyway forgive me for asking but can you help me get home?'

"Unfortunately, we cannot interfere any further than saving you. It's up to you in finding your way home but don't worry you'll arrive soon in another world."(Epoch)

"You have to do something in that world and save it from destruction. We cannot tell anymore but do not worry time ran slower in your world than this world therefore you have my brother in your side when I say brother I meant time."

"Issei Satanael Hyoudou, your road is still not over and it may seem that we manipulating your life but this is the only way to save your world. If those outer gods win then everything would be over."(Enoch)

From the tone of his voice, he was truly ashamed of using Issei but the latter didn't mind as long it was slaying the outer gods and protecting his lovers. He was willing to fight till the end to annihilate the outer God. Furthermore, Issei who had fully fused with Satan adapted his full name.

'If it meant to protect my loves then I'm willing to fight until the end!'

"Excellent answer! You shall go forth in a world where there only magic and ki. Your task not only save one world but two! We will be watching every step in the way, Go forth Son of my dearest friend."

It was then Issei felt the spatial shift and disappeared from the dimensional rift. As the two embodiment disappeared to do their task.

"Please enjoy this warm tea, master."

"Thank you, chanchamaru. It is oddly peaceful today like calm before the storm."

"What do you mean master? The weather is perfect and according to my analysis that it won't be storm coming."

"That isn't wha-"

She then felt an influx of powerful energy in specific spot that made her stood up and dripping her tea. The robot girl quickly clean the table while her master instantly stared at the source.

"Chachamaru inform the principal to investigate the place."

"Understood."

Chachamaru quickly left to inform while the one who arrived was struggling to stay conscious until collapsing on the small crater radiating a thick magical and chaotic energy.
