Prologue

A Great Reminder: This Story is for Monster Lovers! I humbly asks for you to keep an open mind of it and don't curse me or anything since the chapters of "In Another Time, In Another World" will be influence by you when I asks a question.

(DxD Universe #10699)

The Year is 2035, it has been 22 years since a being known as Tyldraiss had invaded the Earth. 22 years ago, there was a peace conference held at Kuoh Academy between not humans, but of the supernatural. Or being more precise, it was a peace conference between Angels, Fallen Angels, and Devils.

How do I know this? Well, I was there from the very beginning of that horrible day. It was that day, both humans and the supernatural had learned the very question that hadn't been answered for ages: are we truly alone in the universe?

Long story short, Tyldraiss intervened at the Peace Summit and outright attacked everyone with his own mechanical soldiers present. By the time we realized we had to retreat to live another day, Tyldraiss not only killed the three faction's guards, he slaughtered most of my friends and injured the presented leaders.

Gasper and Koneko, they were the first to die when Tyldraiss makes his presence known as he exploded the building they are in with his double-headed lance. Xenovia… Tyldraiss snapped her neck as he rids Kiba in half. He used his lance to fire a beam of light that completely destroyed Irina's head before the White Dragon Emperor intervened. Rias Gremory died in the aftermath as Tyldraiss' lance rendered her stomach non-existence before he successfully killed Sirzech Lucifer and the White Dragon Emperor.

Akeno only lost her leg as Serafall and Michael respectively lost their arms as Asia and Azazel were declared MIA. Sona and her peerage received the least injuries and less losses while Grafyia mourns for the loss of Sirzechs as I find out that she marries him and has a child with him.

We thought that at the moment that the Underworld as well as Heaven in Michael, with any holy survivors' case, were safe from the invasion. Sadly, we were wrong… dead wrong! It turns out that Underworld was where the main invasion force occurred as Tyldraiss went off to wipe out the leaders.

Six month… six fucking month… that much time it took for the entire Earth to fall under Tyldraiss as it kills any who dared stand against him. The strongest devils, sacred gear users, Gods… the strongest that the Supernatural have to offer have fallen!

Despite all the losses we have suffered that had happened during Tyldraiss' reign of terror, we still refuse to give in to Tyldraiss and allow our very existence to be erased from the face of the Earth. After all, the Khoas Brigade was founded with determination and hope that we are going to live through this because I am convinced that this is our finest moment to shine in this dark era.

Why do I think like that? Well, we can rely on two things for weaknesses. Tyldraiss is very obsessive when it comes to Ophis and that makes him very sloppy. That and the fact that the monster doesn't know a thing about Infinity Stones: basically six stones of unfathomable powers for it controlled essential aspects of their reality. At the right timing, these two factors will ultimately serve as his downfall.

My name is Issei Hyoudou, former servant to… Rias Gremory, one of the founders of the Khoas Brigade, and the first Red Dragon Emperor who ever wielded an Infinity Stone or two. Even though we have lost friends, family, and loved ones… I will ensure that we will achieve not just victory against Tyldraiss or against these Evies, but victory for all times!

I was prepared to do whatever it takes to restore the Earth and prevent any further invasion should I survive. However, I wasn't prepared for…

Hello everyone, this chapter was meant to be post on Halloween, but I was unable to do so because I had to escort some of my family on Halloween.

Originally, this chapter would have been long as it would covers the question of why I post this story in MGE crossover section instead of High school dxd territory, but I wanted to build some mystery to it. That and I run out of time of constructing the chapter. Seeing Dxd Universe number saying 10699 on this chapter meant I'm taking an AU route instead of Canon so be expected that Issei will be different to the Issei we had watched. My fan-fiction knowledge is only limited to this websites as I have added all DXD fanfics and DXD crossover fanfics together as means of seeing this DXD universe will fitted in our fan-made DXD multiverse. I hinted the year 2013 because that the year of Season 2 was released as DxD fans were exposed of the anime version of Peace Summit arc and the introduction of the first enemy of the series, the Khoas Brigade.

So far, It's my first time of being ExE world since just finding out that the World of DxD will be invaded by Aliens in the foreseeable future was just so nerve wrecking for me to haven't write about that in my older DXD fanfics. Just knowing the fact that one of these evil Alien Gods have killed Great Red is scary to me since Great Red is the baddest and strongest to the knowledge of Draconic Deus world. Tydraiss isn't a canon character, but it's my OC villain character as he is inspired by Marvel What if Ultron, the very same Ultron who fought against the Watcher and the Guardians of the Multiverse. Since this chapter and the next is inspired by Marvel elements, I'm pulling in Infinity Stones as well since I haven't read or watch Shin High School DxD, just reading their information of how powerful are they compared to Ophis and Great Red: I just that the Infinity Stones will be enough to defeat them once and for all as we seen it in the series, Infinity War, and Endgame. The stones won't be liked about we have watched on MCU since I'm still researching about every Infinity Stones of comics and games.

Until Next Time.
