story start

"What have i done?" was the words spoken by a woman in hollow tone.

The same words she said from time to time since 'that day'. The woman looks like in her mid 20 she had a thigh-lenght black hair, a pair of blank onyx eyes, standing around 6"5' in height she wore a tight black leather Jacket with a matching leather pants, black leather gloves and black high heel boots

"All i wanted to do is getting back to dimensional gap and claimed what is rightfully mine from that fool… but… my course of action… led the world to chaos and its untimely destruction" Earth, or what's left of it now covered in ruins, most of the planet now can be described as barren empty wasteland.

"I'm the FREAKING Infinite Dragon GOD! for fuck sake! Why i didn't act like one and i chose the path of Childishness and hell bent on revenge on the Great-Red for taking my Silence!" The woman now started to cry and weeping as she remembered during 'that day' where she lose everything she had care for

"i'm too naive to think they will abide to my bidding but it turns out they had a hidden agenda and backstabbed me and took MY Power for their own Purposes… sob… if only…sob... if only i took my position as their FUCKING leader seriously… i could fight back against them and took several peoples with me so we can counter their plans…" she Inhale "but i've been too ignorant about their hidden agenda and ALLOWED those MORONS stole my power to create another ME to fight for their cause" she started reminiscing the day when People-... no, assholes from Khaos Brigade's sub-faction, Hero Faction used Samael, to extract her power

"If Only i move to stop them back then and ignore my stupidity thinking 'there's no amusement in wiping them out now'... i wouldn't have to worry losing my Issei-Tou-san...and… Rias kaa-chan and my sisters… sob…" now the woman curl into fetal position and more tears flowing from her eyes

"Asia, Irina, Xenovia, Koneko, Rossweisse ne-san, Akeno ba-san, Gasper nii-chan, Kiba Nii-san, Azazel-Jiji…" she cry more as she remember one by one her family were Slaughtered on 'that day'

~Ouroboros~

'that day' was actually the term the black haired young woman use to call the event known as 'the Apocalypse' it's an apocalyptic event when a supranatural Terrorist group known as Khaos Brigade declared war on The Alliances and start attacking Hell and Heaven alike

during the course of the war, Khaos Brigade had many advantages due to the possession of several Longinus Sacred Gear and The Evil Dragons who doesn't even know fear ravaging the battlefield and killing many important members of the Alliances and wiping out several The Alliance's posts forcing The Alliances on a massive retreats

Things looks so bad even with Michael, Azazel, and 4 Satans combined power doesn't enough to stop them and what's worse, Euclid Lucifuge younger brother of Grayfia Lucifuge, manage to recreated Boosted Gear and Divine Dividing alike and used it to maximum potential with a special… upgrade (read: Constant Juggernaut Drive without the need to consume its user's life force)

During the siege, many Soldiers of The Alliances fought bravely against all odds but bravery alone is not enough to stop them. The battle continue for the rest of the day which resulting massive casualties on both sides and the Angels exodus of heaven due to have less personnel and their reinforcement has been cut-off forcing them to evacuate from Heaven and taking refuge in underworld

The next stage of the war was the most bloody of all, the war has been dragged to human realm and the so called Apocalyptic Beast, Trihexa, has been released by the Khaos Brigade and running amok destroying everything in its path and that's including human settlement spread across the globe. Many countries fight back using their firearms, tanks, aircraft jets, and any modern weaponry but to no avail their weapons has no effect on the beast at all hell, several super power nation like America, France, Russia, England, and German launched all their nukes they had at the beast in desperate attempts and its only pissing the beast off no actual damage has been done. The Alliances quickly aid humanity as best as they can holding off the beast while this is happening Khaos Brigade come out and started killing opposing forces

It was a mess, All across the globe the dead bodies of Human and Supernatural beings alike sprawled lifelessly while the those who still fighting watch in horror as the beast never looks tired from destroying everything and keep regenerating from the wounds they inflicted. When all hopes seems so lost, some miracle happened, Great-Red the massive Red Dragon God Emperor came to aid humanity and The Alliances

The battle turned into a stalemate between Great-Red and Trihexa. The battle however also turns from worse to worst, as the two entities fighting each other exchanging blow, the shockwave of the attack act like a tsunami at a speed of mach 10 with a range between 50 miles or more decimating Humans and supernatural beings who caught up in the blast and at the same time each blast destroying Earth's magic Leylines disabling the mages ability use magic and summoning their familiar to fight, Using this opportunity surviving forces of humans and the Alliances wiping out the Magician faction of Khaos Brigade with extreme pre-judice

Flesh and bones met rain of hot lead, shredding their body like hot knife through butter. sound of machine guns, light spears, and scream of agony echoed throughout the skies as the last member Magician Faction drop with a thud and a hole right between the eyes

while that was going on, the Infinite Dragon God, went suicidal move even though she knows she had been weakened, by killing every member of Khaos Brigade Sub-faction known as Hero Faction. Officially, it consists many of heroes' descendant from different mythology but according to the Dragon God personally? it's consists of many stuck-up jerks, assholes, and skanks of a heroes descendant who hell bent on destroying the world where they live in. and the Dragon God have a bone to pick with them. The battle was short but extremely destructive, as the Dragon God unleash her wrath upon them, she unleashed her power without worry the need to control her power as her uncontrol power output enough to reduce everyrhing to ashes. Many of the so called 'Hero' one by one die in her hands. it was a slaughter, none were spared from the Dragon God wrath. Even though she was stabbed, Bombed, shot, and slashed multiple times it didn't waver her resolve to eliminate this faction as they were her greatest mistake in her life and she won't stop until she every last one of them dead. At the end, The Dragon God pass-out from the wounds inflicted upon her especially the wound from that Longinus Spear

on the other side of the Battle ground two young man in a red and white draconic armor stood victoriously against the dead Khaos Brigade leader and the leader of Old-Maou Faction, Rizevim Livan Lucifer and their head researcher, Euclid Lucifuge both wearing the imitations of Divine Dividing and Boosted Gear respectively. Retrieving the last pieces of Sephiroth Graal and combined it with other pieces. Both fighter flew together to join fight against the apocalyptic beast.

The Battle continued for the next 2 days and causing more casualties at this point 98% of world populations including humans, animals and supernatural alike has been wipe-out and Earth's Life force is already dead and, at this point the remaining allied forces including the two young men, Great-Red, and the leader of each allied faction Sacrifice themselves to re-seal- no, slay the beast and in one amazing feat the beast has been slained using the combinations of Great-Red's power, Sephiroth Grall, and the life forces of remaining allied forces

The war is over

With a cost that no one ever imagine

~Ouroboros~

The raven-haired beauty now laying on the ground, her blank eyes staring into the brownish colored sky

"That was a thousand year ago… i can live peacefully for more than 4.5 billion years in silence... but after i met my family i can't even live in silence for more than 1 hour" Ophis said

"My heart now craved for love, compassion, and kindness like the one you showed me long ago" Ophis sighed

She then reaches her pocket and pulled out two pictures.

The first picture was taken by Issei, before they went back home from the hot spring in that picture whole ORC members with Rias hugging Ophis -who's sporting a rare smile- from behind. "Why it had to be you…" she said sadly. The second picture was taken by Rias, her mother-figure, before they went back home after shopping from the mall.

Ophis look at the picture lovingly albeit with a sad face, it's a picture of smiling Issei giving Ophis a piggyback ride with the latter holding a puffy cotton candy "why not me… the one who started this… holocaust… the one who opened the Pandora box and destroyed the world… why not me... the one who created the forces of darkness to... indirectly kill my own family?" she said in depressive tone

"Why? Why took them from me?" she said sadly as tears starts flowing again from her eyes

Ophis take a last look at the pictures before she hug the picture as if she didn't want it to let it go. Eventually, Ophis close her eyes before letting her consciousness fall into darkness as sleep claims her mind and body trying to ease of her pain that were pent up for a millenia
