This the first story that I wrote so please go easy on me. My English is a bit wonky because it is not my primary language so if you see any errors, please tell me via PM or reviews.

Disclaimer: I do not own Highschool DxD and Worm Serial.

Summary: Somehow, Lung got involved in U&L's shenanigans sending his Shard across the multiverse. Somewhere on Earth, a person got hit by a truck. On the void between dimensions, the Dragon of Dragons is bored. In the Human World, A pervert was dying...

P.S. This is a crack-fic. AND I don't care if I got my facts wrong about any of the series, I'm using my headcanon for this one...

Obligatory Reader Review Response Corner

First and foremost, I would like to thank everyone for their support and positive reviews...

Chris Kidder (Guest): I am limiting Issei's Dragon form to Great Red Size. As for the fight against dragons... Well, I'll get there somewhere. I already planned for a fight against Trihexa. IT WILL BE GLORIOUS!

Ahliswashere: he went Balance Breaker because of the massive energy that he has gathered. When the Fallen turned him into pincushion, his consciousness slipped for a moment due to the pain causing his primal instinct (due to Dragon Form) to use anything in its disposal to finish the threat.

H20 Ferrum Dominos: Yes, that old blood-sucking troll and that overgrown lizard are in contact with each other...

Rias couldn't help but feel frightened of what she saw.

It has been four hours since she and Sona felt the massive spike in energy in the area. Both of their peerages have sent their familiars to check but somehow, whenever they are close to the area, they always turn back and run away despite their master's commands.

They have also tried to contact their siblings, the Maous, however, all transmissions were disrupted by the saturation of foreign energy lingering in the air...

So four hours later, they decided to teleport into the area, hoping that whoever was the cause of the energy was already gone or have already calmed down.

Right after her peerage flashed out from the teleport circle, what greeted them was a scene of carnage. The park was wrecked, the fountain was turned to rubble, the gouges and craters littered the ground, trees were upturned, and most importantly, the four dead fallen stacked in the middle of the park.

"Dragon..." she heard her Rook, Koneko, murmur.

"Ara~ ara~ " Akeno, her Queen, said, "It seems that we have a dragon in our territory, Buchou~"

"It makes sense," Rias replied, "a dragon can easily release that much energy in one go."

"But the question is, buchou," Her Knight, Kiba interjected, "what kind or who that dragon is."

Rias was about to reply when she heard Koneko. She, herself, trembled at her Rook's words.

"It's... here..." Koneko said as she shivered.

-break-

Issei couldn't remember what happened. When he came to, all Issei saw was the dead Fallen sprawled on the ground. All Issei remembered was pain and then nothing.

Looking at his left hand, he couldn't help but grin.

"With the shard, I could theoretically battle that Goddamn Dragon," Issei said out loud. "But with you, I am sure I can defeat that overgrown lizard, so pleasure working with you, partner!"

[It seems that I ended up with a strange host] The emerald in the gauntlet flashed as a voice echoed from the gem. [A displace soul with a part of an interdimensional entity that makes the host stronger as long as there is conflict. It seems that you'll be the strongest Sekiryuutei in history]

Issei just gave a grin.

"No Ddraig Y Goch," He declared, "You are the only one deserving the title Sekiryuutei. I shall be known as the Dragon of Escalation!"

[Hahahahahaha! Very well partner! Let's show the world the power of DRAGONS!]

It was a few minutes later when Issei was informed by Ddraig that her supposed 'master' was about to arrive.

So, having prepared for a dramatic entrance, Issei hid behind one of the remaining trees after he piled up the fallen.

"It's… Here…" As soon as Koneko said that, everyone in Rias' peerage went battle mode.

Rias brought forth her family's ability, "The Power of Nothingness". The ability to eradicate anything. A power from her Bael Bloodline.

Akeno was coated with lighting.

Kiba called forth his swords.

Koneko tugged on her leather gloves.

Then, they heard the crunch of gravel. The peerage, as one, turned their heads to the remaining tree standing at the park.

There stood their newest peerage member, one of the Tree Perverts of Kuoh Academy, Hyoudou Issei.

"Issei!" Rias sceamed out, "are you alright? Did anybody hurt you?"

Issei just smiled, "No. Everything is fine, master. As you can see, we creatures of the underworld would never agree with the winged ones, so I took care of our crow problem."

Rias and her entourage was taken aback by what Issei had implied.

He knew he was reincarnated into Rias' peerage. He knew that they were devils. He knew that they were fallen. And he killed them.

All these information was swimming inside the head of the entire peerage. And what they thought stopped them in their tracks.

"I-Issei," Rias stammered out, "were you the one to do this?"

"Ah," Issei replied, "I'm sorry for the inconvenience, master. These crows tried to kill me, so is it not polite to kill them in turn?"

The whole peerage just stood there. Issei and The rest of the peerage just stared at each other.

Issei was smiling pleasantly while the rest of the peerage was filled with awe, fear, and… arousal?

"Ara~ ara~," Akeno practically moaned out. "It looks like newest member is not as ordinary as we assumed, Buchou~"

Bonus Omake:

Issei stepped out from the Dragon Gate. He stopped for a moment to observe his surroundings.

Since he became an Entity like Zion and Eden, he have visited countless realms with the help of Great Red. Now, he can do it alone. In fact, he considered himself as an expert in Dimensional Travel.

'ah! It seems that one of my shard finished identifying where and when I ended up in' Issei thought. A few seconds later and he burst out laughing.

He's in Shanxi. Before the First Contact war...

Suddenly, Issei was hit by a practically insane Idea.

'Yes... yes... that would provide me entertainment for a long time' He cackled gleefully.

Pulling out a shard for time traveling and teleportation, he popped up at Earth just before the discovered the Prothean Cache on Mars.

Then, he pulled out his Shaper and Master shard.

Sending out a pulse, he altered the brain of the Humans of Earth to have a Corona Pollentia. Then sending out another pulse from his Master shard to alter the memories of the humans to think that having a Corona Pollentia is normal.

'Now, let's see how the Citadel and Reapers react to Parahumans'

"So amuse me, Mortals!"

Life's a bitch... An absolute bitch...

We had about three days of rest... Then a month of tests and activities...

Anyways, please read, follow, favorite, and review!
