I DON'T OWN High School Dxd or Date A live. They goes to the rightful owner.

Sorry for story-rushing. I still Noob:v

I, Hyoudou Issei after taking khaos brigade in Underworld, feel exhausted in the train.

My body feels heavy yet my mind feels light. My beloved Rias was there with Akeno-san. Yeah, there wasn't any problem again. Cao-cao was beaten so he won't attack again... Huh i become sleepy? What's going on Ddraig?

When i wake up, i was in park, Lost.

"Huh where am i? I though i was in underground train in underworld".

"Aahhh what the heck i am doing here? Is this tokyo?" I muttered.

"Rias!Akeno-san!Asia!" But there's no whatever. I think i must search upon the town...

While i walking around town, i see a boy with a loli girl talk in front of a restaurant. "Huh? I though there wasn't a restaurant in place like this. What is this place?"

" ...you have to be there even if an earthquake starts or a fire erupts or a spacequake happens or the family restaurant is occupied by terrorists!"

...earthquake? Terrorist? What the fuck with this town! While i think how to escape from this town, a voice suddenly appear.

[How do you do, sekiryuutei?]

"Who is it! What the fuck are you doing to me!"

[You are in a paralel world. Thanks to my sacred gear, i can separate you with Rias Gremory. Now i can lead the gremory group into destruction! hahahahahahahahaha]

"Don't talk nonsense! If you brave enough, fight me!" I took out my balance breaker state.

But my aura makes earthquake in entire town. "Emergency! Spatial quake detected. Please evacuate imideatly"

... spatial quake!? What now!

From afar, i see a soldier team flying. FLY?! Even soldier can fly!?

"There's the spirit! Kill her!" The soldier team begin to shoot at me.

WHAT THE FUUUUUUUUUUU...only because i create an earthquake, i commited crime?! I'm sorry!

While i being chased by soldiers, another quake occurs. "Why this town has many earthquake!?" I run into earthquake source. A purple haired- girl was inside the crater. "Soldiers!" That girl begin attacking the soldiers with a sword. "eh, i don't see wrong, am i?" That girl fight soldiers in the air. " i think i should help her." I cast dragon blaster to a soldier. But my attack missed. What a pain...

Well at least i have ascalon in my hand... But i was exhausted so i can't use my dragon wing. When i think how to defeat the soldiers, i accidentally use Dress Break towards a soldier's armour was broke. Thanks for the meal! I will save it in my brain! Fortunaletly she wasn't see on this side. I can't imagine she will become koneko-chan...

The fight last 30 minutes.

"Retreat! I repeat retreat!" Then the soldiers fly away.

"Thank you"

...eh

"For helping me chase away the soldiers."

"Ah no need to thank you. Actually i was chased by that soldier."

Suddenly, a blue haired-boy came. What is his point?

"Wha-"

The girl pointed her sword to the boy.

"You too huh?"

"!?"

Why that girl threaten the boy? What's happening here?

"Wait! What are you planning to do?" "Kill him, of course."

"W-why?"

"—After all, didn't you come to kill me too?"

What!? That boy? Kill her? This bishoujou!? There's no way i let that happen!

"...There's no way I would do that."

"—What?"

A moment after that, a soldier come and try to shoot us.

"... tobichi ... origami?"

Who the heck is that?

[Partner!] "Ddraig! What's going on here?"

[I don't know. Maybe you and that girl was the target?]

Me!? Agaiiiiiiiiin?!

[For now, let us help her fight the soldier.]

"Yeah, that will do."

Illegal move trident, knight mode!

"Sonic boost!" I streak into the soldier's back

"Solid impact!" I punched the soldier until bouncing into mountain.

A moment after that, i lose consciousness due out of energy.

When i wake up, i was in the park again. My body feels heavy.

"What again?"

"Ise-kun!" Huh?

"Irina! What are you doing here?"

"I don't know. When we investigate your lost presence, i fell asleep and wake up in here. What is this town actually?"

"This is paralel town casted by a member of khaos brigade. Be careful. I was chased by soldiers back then"

"Wha... then should we go to town?

"Geez, why you asking about that? Are you want to stole me from rias?" Sigh...

I ended up having date with Irina, my childhood friend and reincarnated angel... wait, are devil and angel supposed to hostile? Ah i don't care. Having a person i know is enough. Also, i can search that bishoujou in this town... My harem plan!
