Prologue

? POV

Another normal day at school, it's been 17 years since I was born in this world

You must be confused by what I mean, this world aren't you? Well the truth is I'm not who I am, strange huh?

Anyway, my name is Kai, but my name from before was Leon, Leonard Ang. You see I'm not originally from this world. I was doctor before; well you could say new Doctor. I just graduated from a Medical Student 1 year prior, and I'd like to tell you all about my previous life, but that's another story. I will tell you all what happen to me before I born as Kai

One day I was about to go home from hospital, as new doctor I still work as a secretary under a senior doctor, at that time. When I was about to cross the road my phone started ringing. I notice the traffic lamp was still red so I decide to answer. It was call from my mother; she was saying she had some problems with my father, who was drinking somewhere. So she asked me to pick him up, since the bar my father liked, is near my work place.

While I was talking to her I noticed the traffic light become green so I decide to walk while talking on the phone, however what I didn't notice, was that some truck was moving so fast. It seems like the driver in hurry so he/she decide to run through, and ignore the traffic lights.

That's when everything goes to hell.

At last moment I manage to look at the truck since I hear someone screaming, the last i see was the lights from the truck before it hit me. At the time I feel like I'm flying, and suddenly, BAM! I feel like my backs being crushed by a mountain. I can feel everything slipping; going black. I also notice one other thing…I was going to die.

With this realization I recall my life. I was able to remember when I graduated from high school with my friends, I remember when I played with some cadaver, when I was still in college, I remember when i laughed, when I was sad, when I fought my parents for my girlfriend, who in the end cheated on me.

And I realized one thing...

My life is Seriously Boring.

I study for 12 years in school from elementary to high school, without any thing interesting happening, then I spend 7 years to become doctor, not to mention I was nerd. While I thinking about this I can hear several people screaming, and my body being lifted but it useless, I can feel life start to fade from my body, I can't even open my eyes. I must have hit my head hard for me to rupture my optic nerve; I mutter one thing before I succumb to the darkness

"I wish the next world is not boring like this one was."

With that my body went limp.

First thing I noticed when I died was; It's dark, very dark, it's also frightening, I feel fear start to crawl down my spine, I move, or I try to move, but somehow my body seems to have a hard time to moving!

Then suddenly i feel something pushing me from behind! I was about to turn and see what push me but i can't! I can't see anything! It is to dark!

The darkness does not stay for long...

I suddenly see light. Yes a light! I can feel my body being pushed to that light! I didn't think anything about that at the time; I was just thinking to get out from this darkness!

To that light!

With that I try to move to the light, being helped by something that pushed me on, more precisely I helped pushing me, when I reached the light, suddenly the entire world was a blur to me. It wasn't quite color blindness, but the easiest thing to see was the stark contrast between light and dark.

I could see shapes and edges but the world looked incredibly confusing. Now this isn't what I expected. I was thinking, trying to see where I was, but something blurry like this?! No, not something expected at all!

I was about to speak, but I found no words, rather it's more like Babbling? I then yelled, shouted, roared, but my voice it seemed to stay away! I can felt something wetting my face. I tried to touch my face, but I found I can't move my hands or legs! I can feel I was being lifted and carried.

Now I know I'm not that tall or heavy but…This is ridiculous! I can fell I am been held in the crook of someone's arm! What is carrying me, a Giant; a Monster?!
Once again fear started to crawl through my body. Naturally I was not the type of person who was easy get afraid of something. I mean I have seen cadavers that only have half a face, cadavers who got it guts spilled, locked alone with a dozen corpses, seeing a gruesome wound from patients, but I don't know why I am afraid now.

Seeing talking and shouting were useless. I did the only thing I could have. I screamed. I wailed. I cried

17 years later

"Onii-san... You doing it again aren't you?" I asked as I see the boy that become my brother in this new world... Twin actually when web born he was the first to exist from mother womb, 1 minute 37 seconds after me. My brother jumped in surprise and turn to see me with sheepish look

"Aah Kai! You startled me!" My brother said in a sheepish tone from the bush

My brother has hair that reminds me of Jin Kazama from Tekken, except he has more bangs covering his forehead, and it was light brown instead of black like Jin, followed by light brown eyes. This boy like me and our parents, all have brown hair; everyone in my family has brown hair and light brown eyes, except I have black eyes for some reason. My brother seems to have inherited his hair from my father, while I seemed to have inherited my hair from my mother, seeing as I have straight hair like the Prince in this school, Yuuto Kiba.

"Seriously Nii-san, you need to stop this, you're lucky that I able to save you last time" I sighed

"Hey! If Matsuda didn't yell my name I wouldn't have been caught!" He retorted

"And that's why I forbid you to hang out with them!" I glare at him

"Ah come on Kai you no fun! I tell you its fun to be along with them!" He pouted

"Yeah but it's no fun seeing your brother get pummeled by girls! Seriously you are human, I don't know how you are able to handle the beating that Kendo club gives to you" I protested

Ah yeah I forgot to tell you. I was... Well you could say now I am in the DxD world, you know right? The world where Devils, Fallen Angels, and Angels exist...

And live among us...

Now you wonder how I can know about this world right? We'll let just say my friend is otaku, and a hard one, a pervert otaku you can say as well, and DxD is one of her favorites. Yes my pervert friend was girl. Don't be surprised, woman can be pervert too you know. Why do you think they are drooling when Korean Artist remove their shirts while singing?! Even some of them throw underwear! For god sake, underwear! We men maybe perverted, but we won't throw our underwear to the stadium when our favorite singer sings! That's was crossing line damn it!

Anyway I went off topic, I was reluctant first to watch the DvD that my friend gave me, but seeing at the time I bored, so why not? I mean I'm a man, and to like the lady's body is in our nature. I watched DxD until Vail declared he was a Descendant of Lucifer, and after that I stop watching, but still even if I watched DvD, I still somehow find it hard to remember, as if it was a blur. Yeah. I don't even remember all Maou's names, except for Sirzechs and Serafall... Those two are really funny

"Oy! Earth to Kai! Earth calling Kai! Mayday! Mayday! Come in Kai!" My brother waving his hand in front of me broke me from my memories.

"Ah, sorry Nii-san, I just got up caught in something" I rubbed my back neck before I clear my throat. "Anyway let's get you out from here before Katase-san and Murayama-san find you" I said and started to drag him by his shirt collar.

"Ah! But they just removed their cloths! I will able to see their oppai! It just got to the best par-"

"GGYAAAA!"

My brother was silenced when we both heard someone screaming. I'd take a guess Matsuda got caught and soon Motohama will be as well.

"AAAAAAH! NOT THERE! DONT STRIKE THERE!"

"You were saying Nii-san?" I said with deadpanned expression

"Thank you?" He said unsure, and I sighed

Yes, my brother Hyoudou Issei, the protagonist of the story. One of perverted trio, the self-proclaimed Harem King, when he becomes a devil later anyway, and we are at Kuoh Academy, a school that was ruled by the Sitri and Gremory clan's heiresses, Sona and Rias respectively. When I said the world was boring I didn't mean to send me to this one here damn it! Not to mention I was always going around with the protagonist, who always got hit by Murphy law!

"Kai-kun" a feminine voice to called me as I was dragging Nii-san away. I turn and see Katase and Murayama standing there. I can see Nii-san becoming pale, but I kept a calm and stoic expression.

"Ah? Hello Katase-san, Murayama-san, kendo club. May I ask why you are surrounding me?" I asked in a polite tone of voice.

"Well, Kai, you see we just caught two of perverted trio peeping on us... Again, but we were confused when Issei-san wasn't anywhere close by." Katase said sweetly

"Well Katase-san as you can see my brother's not peeking at you, we were just walking around, Right Nii-san?" I asked to my brother who nodded.

"Ah yeah! The weather is good today! Ahaha" He laughed nervously, very good act Nii-san... Murayama narrowed her eyes

"Now Murayama-san, Katase-san, you all didn't have proof that he was peeking at you, so may we go? I'm sure Sona-Kaichou won't like if I reported to her that you were beating my brother without reason." I said calmly.

"Why were you thinking we are going to beat him? You dont have proof." Katase smirked, but I stay calm

"Well seeing the girl behind you just ripped Nii-san's picture, and looked at him with deadly eyes, isn't it obvious?" I smirked a bit and Katase turn to see one of club member blushing before she turned to me again with frown.

"If you say so... You win again, this time Kai-kun. But don't think you will able to protect him forever" Katase said with a glare to Isse first before she turns around to leave.

"See you next time Kai-kun" Murayama smiled and winked to me before she also turns around to leave.

Of all Kendo club member only Murayama seems kind to me, well after all I got through teaching her a few tricks in Kendo at least. Yes I was also in the Kendo club, but for boys not girls.

I also able at defeating our teacher with ease, how can I be so good at martial arts you ask? Well I have been learning Martial Arts since I was 9. Ise-nii also learned some Kendo movements, I was the one who suggested it to him and he accepted it. I said perhaps it will become useful someday, but the truth is I trained him and myself in order to prepare for the future. I don't know if I should prevent him from becoming a devil or not, but if he is the protagonist then I don't have choice. As for me I don't know, perhaps I should stay as human

"Thanks for the save Kai, man that was close" Ise-nii sighed in relief

"Anyway, class is about to start. See you after school Nii-san" I waved my hand and started to leave, my class was different from his I don't know why the Council separated us.

"Hey look. Its Kai-kun…"
"He's handsome as always..."
I groaned mentally, but on the outside I keep my face stoic. Fan girls damn it! You know, in my previous life I was curious how it was if you have fan, and now I wish I kept my mouth shut. I notice another set of squeals from the girls around me.

"Kai-kun hey!"

I turn around and see Yuuto Kiba smile to me, and I nodded back Kiba and I are friends, though not the best of friends,t he will help me if I ask him. We also has same problem…

Fan girls...

"Hello Kiba. How are you?" I ask him.

"I'm fine, how are you?" He was still smiling at me.
"The usual, saving my brother from the Kendo clubs wrath" I sighed a little and he chuckles

"As usual eh, you know if wasn't because your face was a replicas of his I wouldn't believe that the two are twins" He chuckled

Well what can i say? We are twins so it obvious we have the same faces though our hair is different. Seriously Nii-san is not bad actually, he maybe not handsome like Kiba but at least he good looking, the only thing that make girl stay away from him is his perverted nature.

"Yeah, but Nii-san isn't Nii-san if he not a pervert" I chuckled, making Kiba laugh

"True, true, anyways the bell will ring soon; I will go on first, see you later." Kiba waved and I nodded

"Yeah, see you later"

"You WHAT?!" Mother, Father and I yelled in shock
"I got a girlfriend!" Ise-Nii grinned to me

While my parents seem happy I'm not! If i recall this is where Ise-

"Her name is Amano Yuuma, she ask me out just before I meet you at the gate" Ise-nii chuckled

Oh crap if I recall her name was.. Laynaa-, Raya-, Lowyale? No. Damn it! I forgot her name!

"Hey Kai what's wrong? You seem pale? Are you sick?" Nii-san asked me

"Err... I don't mean to mock you Nii-san., but seriously, some girl asking you a date? Nii-san I admit you aren't ugly because saying your ugly is the same as saying I am ugly too. What makes you not popular is your reputation as a pervert, and now out of nowhere this girl comes and asks you on date? Don't you find it strange, have you asked her why she wanted to go out with you?" I said this worriedly, and this also got mom and dad's attention

"Hey! Don't you believe in my charm?!" Ise-Nii said in hurt tone, and we just stare at him with deadpanned expressions.

"Does it need to be asked?" I deadpanned, and I can hear a SNAP sound inside nii-san body

"You hurt me Kai..." Ise-Nii murmured in hurt tone

"But what Kai said is true Ise. You have to be careful okay?" Mom said with a worried tone and Nii-san nodded.

"Don't worry! I will introduce her to you tomorrow Kai! Our date is this Sunday, I mean 3 days from now! You have to see her Mom, Dad, Kai, she a beauty, with big oppai!" Ise-nii said with perverted face that makes me roll my eyes, sure she is a beauty, she was Angel after all, before she became a Fallen Angel.
