This is a story of epic proprosions. A crossover between Gurren Lagann and Highschool DxD

Simon's "magic" is indeed spiral energy, and he will get a harem.

Chapter 1: My drill...

"Impossible! Sentient life-forms can't possibly escape from a muti-dimensional labyrinth."said tha anti spiral letting all his anger out.

" Don't underestimate us. We don't care about time, or space or... multi dimensional whatevers! We don't give a damn about that. force your way down a path YOU choose to take, and do it all yourself! That's the way Team Dai-Gurren rolls!"

"EVEN WHEN TRAPPED ON KARMA'S CYCLE" NIA SHOUTED

"THE DREAMS WE LEFT BEHIND WILL OPEN THE DOOR" Yoko followed

"EVEN IF THE UNIVERSE STANDS AGAINTS US" Leeron continued

"OUR BURNING BLOOD WILL CUT THROUGH FAITH"

"WE WILL CUT THROUGH HEAVENS AND THE DIMENSIONS! Simon finished

"AND WOULD STAND AGAINST WHO TRIED TO STOP US TO GAIN A LITTLE OF OUR FAITH!" All said

"TENGEN TOPPA GURREN LAGANN!" Simon shouted

"WHO THE HELL DO YOU THINK WE ARE!"

And the dai gurren brigade clashed their drills with the anti spiral's

Until the Tengen Toppa Gurren Lagann is inmovilized and they keep atacking with the chou ginga gurren lagann, until it gets inmovilized, and then they keep atacking with arc gurren lagann, until it gets inmovilized so Viral and Simon keep atacking with Gurren Lagann but they got inmovilized too. Viral makes an attempt to get Simon to Lagann Impact the shit out the anti spiral. Lagann's drill is about to pierce the anti spiral, but the anti spiral has one more trick under it's sleeve.

"Spiral destruction: DIMENSIONAL OBLIVION" The anti spiral said when a barrier appeared in front of him. It looked like a dark violet and black spiral wall.

"LAGANN PIERCE THROUGH IT!" Simon shouted as lagann destroyed the barrier pierceing through the anti spiral.

"I TOLD YOU WE DON'T CARE ABOUT DIMENSIONAL WHATEVERS" Simon said feeling the sweet victory.

"Oh you mean the dimensional oblivion? Well the point of it isn't protecting me, is traping the spiral energy." The anti spiral said with a smirk but I think taking you and your spiral friends will be enough."said the anti spiral.

"What?!" Simon said

As a portal that was like the door Simon broke absorb Simon, gurren and lagann.

"What?!" Yoko said as she saw viral floating on space " VIRAL?! Why is he there and not in the portal?" While Dayakka and Darry took him inside the ship.

"Viral is a beastman. He's artificial not a spiral being."

"So Simon, Gurren Lagann and Boota are gone?!" Said Viral as he heard what happened.

"Boota?" Said a confused gimmy.

"He helped with the spiral energy and turned into my "co-pilot", remeber." Viral said.

Yoko between her tears was able to see Nia. She was... smiling?

-Highschool DxD-

"Issei" a girl with a sweet voice to her new boyfriend.

"Yes Yuuma Chan" the boy answered with a stupid face thinking in all the lewd things they would do together.

"Would you die." She said while changing her close into only leather straps and grew a pair of black as the nigth wings.

The surprise on issei's face that you would see once in a life time.

But suddenly roles changed as the face raynare put when she saw the two giant robots that appeared out of thin air.

As a robot as big as a 12 story building fall on her ex girlfriend and winged killer and a smaller robot the size of a human fell over him.

"I wish I am dreaming" issei said as he move out of the way.

"Your wish is granted" he heard a femenine soft beutiful voice said. And then lagann fell over him.

That is all he could remember as he wake up in his room the next day thinking everything was a dream. But he didn't notice a card that said gremory on the side of his bed.

-the night before: destroyed park-

"Ara ara buchou, what problem did you got yourself into" said a dark haired, purple eyed beauty

"Don't really know aken... eek" said the red haired girl "A rat" she said as she charged her magic in her hand to kill whatever that was.

Boota saw what she was doing so he got up on lagann and then on the unconcious simon and get himself into a defensive position.

"Look buchou isn't that cute that is protecting him" said the purple eyed girl.

"Him? There is a person there?" The red head called "buchou" by her friend said.

"Yeah, and quite a handsome person"the dark haired girl said "He is quite damaged"

"Let's take the robots to my families mansion and heal him there then." Said the red head

"Sure thing, buchou" said thd purple eyed girl.

-Simon's dream-

"Nia!" Simon said as he saw the woman he just did the imposible for.

"Goodbye simon" Nia said smiling.

"Goodbye? I'll be back this isn't a goodbye." Simon said pretty confused.

I meant I will desapear and there is nothing we could do about it ." Nia said trying to explain better the situation.

"Wait WHAT?" Simon asked with chills going down his spine.

"Without the anti spiral I can't survive anymore." Nia said crying "So I came to say goodbye" Nia said and couldn't control herself anymore. She started crying and crying as she joined Simon for one last kiss. "Simon please. Don't let my death stop you from achieving hapiness. Have a family, have kids, tell them about our adventures with the dai gurren brigade."

"Why would I have childs if you're not there to raise it" Simon cried to Nia as she was fading away.

"Come on Simon let me see you grit those teeth." Said Nia before fading away completly.

"NIA!" Simon shouted before feel like he fade away himself.

Simon woke up covered in sweat, nervous and... nude?!

"Ah I can see you woke up? He heard a beutiful soft voice say.

So what do you think about it? Liked the idea and want to see more? Leave a review saying that.

You didn't like it and think simon should stay virgin and the only thing he can pierce are the heavens? Leave a review saying what you didn't like.

Any suggestions? I would love to listen to them

Do you want an harem? Only one girl? Bring someone from the Gurren Lagann dimension?

Akeno for Simon

Asia can't decide

Rossweise for Simon

Grayfia netorare Simon time
