Earth.

Yes, a very beautiful blue planet in the solar system. The only planet that has residents. A planet that has a life consisting of humans, animals and plants. Many beautiful scenery stretching out on this beautiful planet. It's fascinating.

But, that was before. Now the planet earth known as the blue planet turned into a dead planet. Life will perish in a few seconds if living there. Because the planet is surrounded by a very thick black fog and contains deadly poison. The cause is the remains of an explosion of an unknown space object until now knows what kind. Whether it's a meteor, a comet, an asteroid or other space object. Scientists can not predict what extraterrestrial objects have made a cataclysmic catastrophe on earth, causing heavy casualties and virtually destroying parts of the earth.

For that, the remaining man and survived the great disaster then decided to move from the earth. They build a new life on the Moon, Mars, and even Jupiter. They must do all that because the earth is uninhabitable. Therefore, the remaining generations continue to try to uncover the mystery of the cause of the earth into 'Black Planet'. So the remaining humans built a special organization to carry out the mission. An 'Expeditionary Forces' organization was formed or abbreviated as PEB.

Then the PEB members were sent to carry out an expedition to the earth known as the 'Black Planet' now. The members of PEB must take a sample of particles of the remains of an outer space that has hit the earth. In order to pass through an area of the earth that already contains many deadly toxins and gasses, scientists have designed a special costume and a large supply of oxygen to sustain the lives of PEB members upon arrival on earth. They were given about three days.

There was a very mysterious incident, when some volunteers and scientists sought to research the Black Planet. The space parties do not capture the response and infrared sensors as a sign they are still active or moving while being monitored through a digital monitor computer. Their response simply disappears as it passes through the black mist that shadows the earth's atmosphere. Communication contacts are cut off. This raises some very panicked people.

Then the relief troops dispatched to check what happened there. However, just the same as before. The troops were suddenly lost in the black fog that shaded the earth. So that contact with the relief team can not be done by the PEB.

Because of the incident, PEB was dissolved and the mission to find out what causes happened on earth finally closed. The so-called Black Planet Earth is branded as a forbidden and dangerous planet to visit. To that end, space parties are strictly forbidden to approach the planet. Anyone who violates will be subject to applicable sanctions.

AKADEMI PILOT OUTSIDE ANGKASA (APLA), 08.30 AM AT LUNAR TIME

Four hundred later, space parties formed an interplanetary fleet called the "Galactic Guard Fleet" aimed at protecting the planet from happening as it does on earth. So the younger generation who continue to be born for four hundred years, they are educated to become a space pilot. So the space agency built a special school for aerospace pilot named Academy of Space Pilot or abbreviated to APLA. The academy is centered on the Moon.

To get into APLA is really difficult, only a few people are fit to go in there because there are some tests done. Among other immune tests, written tests of space knowledge, IQ tests, and others. It's a lot of testing to go through considering it's going to be a space pilot. Because a space pilot must require some skill is adequate. Not just smartness is preferred, but also must have a very strong body resistance.

Yes I'm here. I'm a boy who made it into the APLA. Glad it's not playing. I'm really glad I made it. Because from the first, my dream was to become a space pilot.

Oh yes, I have not introduced who I am. Okay, my name is Uzumaki Naruto. Usually called Naruto. My age is 15 years old. The right age to get into APLA. Moreover, I just graduated from the School of Space Flight. Then after graduation, I immediately enroll myself into APLA. I want to try it first. Where do I know I graduate?

In fact I did graduate, now I'm standing in front of a huge digital screen and hovering in the air. I sharpened my eyes to see a row of photographs along with the names of successful graduates enlivened on the giant digital screen. I kept paying attention to the entire photo of the registrar. Then my eyes stopped to a name that was listed there.

My photograph and my name are written among the graduating applicants. I cheered as I clenched my hands in the air.

"YEAAAAAH, I GRADE TEST!"

Spontaneous because of my super loud screams made everyone who was there to look at me with a blank. They display each sweatdrop.

I realized the strange look of the people there. Then I laughed with a scratch as I bowed half my body.

"Ma-sorry," I told the people there.

"Ah, very basic."

"Just because you pass APLA until you get it?"

"Duh, it's a pleasure to graduate."

"Aaaah, I did not pass."

"YEAAAAAAAAAH, I AM PASS. I PASSED TEEEES!"

There was a very loud scream above my voice, and I turned to the sound.

There was a brown-haired man with the color of his eyes. He was overjoyed to let go of his laughter by clenching his hands into the air. Just like the thing I did earlier.

BLETAAAK!

Suddenly a long orange haired girl tied twintail, he immediately stubbornly stabbed the man's head.

"BASIC, DO NOT ASK SOON, ISSEI!" spouted the girl with fiery "YOU'RE SHOULD KNOW!"

The man who was mocked just complained of pain while stroking his sore head.

"Go-gomen, Irina," replied the man with a sullen face.

The girl known as Irina - I know from this brown-haired man when mentioning the girl's name - just folded her arms across her chest as she stared at the giant digital screen.

"So you graduated too?" the girl asked incredulously.

"Of course, I graduated, you just graduated," said the man named Issei. He held his hands behind his neck.

"Hehehe, I know, you're smart too."

The girl chuckled. The brown-haired man looked at him in a fury.

"You're teasing me?"

The girl's laughter vanished and turned into a bland smile.

"No, that's not what that means."

"Huh ..!"

The man looked away. He's still annoyed.

I'm stunned to watch them both. I smiled.

"What a fun couple."

I decided to leave the place. I want to go home and tell this good news to my grandmother. Surely he is happy to hear I've passed APLA.

BRAK!

When I turned around, I was shocked because I had hit someone. Someone was about to fall back. I realized it and instantly caught his hand.

GREP!

The man's hand I managed to catch. Someone did not fall backward. Thank God.

Someone is an indigo long-haired girl who tied two. Both eyes are colored like lavender. Her face is sweet. I was stunned for a moment.

'Waah, this girl is cute too,' I wondered in my heart.

The girl was amazed to see me who stood. Then he glanced at his hand that I still held tightly.

"Ma-sorry," the girl said. Makes me re-conscious.

"Ah, yes," I said, lifting my eyebrows high.

"A-ano, ma-sorry, can I let go of my hand?"

I realized I was still holding the girl's hand. With a flushed face, I let go of my hand from the girl's hand.

"I'm sorry," I said nervously.

The girl just nodded softly with redness on both cheeks. Apparently she is a shy girl type.

"No-but-thank you for helping me."

The girl smiled. Makes me stunned again for it.

Suddenly there was a voice calling.

"HYUGA HINATA!"

We turned to the origin of a voice not far from us standing. Then found the figure of a flat-faced man with the same face with this indigo-haired girl tied up in two.

I looked from a distance. The man looked at me with a look that I could not interpret. His gaze was very sharp.

"A-ano, my brothers call me," she said, bowing her half. "Te-thank you again, hope we can see each other again."

After saying those words, the indigo-haired girl just walked away. I was stunned to see that in such a hurry.

"HEY, WAIT!" I called to the girl.

But the girl did not listen to me. He kept running toward his brother standing up, folding his arms across his chest. The type of man who is very arrogant and overprotective towards his sister.

I stared at the girl's departure with her sister toward the door of this hall. I feel there is something strange to me now. I do not know why I felt pounding when I was near the girl.

A smile was engraved on my face.

"Yes, I hope I can see the girl again."

I started walking to continue my intention to go home. But, suddenly I bumped into someone again.

BRAK!

This time not a girl. But, a man with black hair with a force sticking up. His eyes are dark. Her skin is white. I know him very much.

"TE-TEME!"

"DOBE?"

I pointed his finger right on his forehead. The man whose full name Uciha Sasuke looks at me flatly. Then he brushed my hand that pointed at his face.

"Get rid of your finger," said this man named Sasuke.

I was too nasty to hear it. Sasuke looked at me flatly.

Silence. We both paused. The atmosphere in the hall is still crowded because many applicants want to see the results of the APLA admissions test. Until today still sounds noisy the registrants are happy and some are not happy.

"You passed here, too, Dobe?" Sasuke asked, breaking the silence.

"Yeah, you graduated, too?" I asked back.

"Of course I passed this APLA."

"That means when you're at the Space Flight School you can prove it too, I applaud you."

I gave my thumbs a big grin for my best friend named Sasuke. He was my best friend during the Space Flight School.

Sasuke smiled thinly.

"You speech will pass in APLA, you can also prove are also great through these difficult tests."

"Heh? You lower my ability, of course I can pass through all the difficult tests in this APLA ...," I said while rubbing my nose. "My mission wants to go to that black planet. wants to be a space pilot. "

Sasuke widened his eyes at my swordsmanship.

"Ka-you still want to continue your intention to go to that forbidden black planet?"

I glanced at Sasuke. I'm still grinning wide.

"Yes, of course."

Sasuke stunned to see me. A second later he smiled.

"Okay, I'll support your dream, Dobe."

"Thank you, Teme."

We both shook hands. Both of us do have a veiled intention behind this entry into APLA. That is, we want to be a space pilot and want to reopen the mission of earth expedition to find out what happened so that the loss of those who used to do research there. This made both of us very curious about what happened on the Black Planet. We want to find out. Especially this concerns about our parents both.

Yes, I remember that my grandmother once told me that my parents and Sasuke's parents who were both scientists and space pilots lost them during their expedition to the Black Planet in secret. At that time me and Sasuke are both still babies. Both of us are entrusted to their families. I was taken care of by my grandmother named Tsunade. While Sasuke raised by his adoptive grandfather named Orochimaru.

Both of us have grown up until now. When we were ten years old, our grandmother and grandfather told us that our parents both disappeared during the expedition to Black Planet and to this day their fate has not been known yet. Either they are alive or not. However, this certainly makes me quite relieved to find out. That Sasuke and I still have parents. Not considered an orphan as people think we are.

We were determined in our hearts that we would follow the Black Planet to search for our lost parents. Although it is illegal and illegal. However, at least I can investigate also what caused the earth to crumble like that. There must be something hidden beneath the thick black fog that shadows the surface of the earth that makes the earth like a dead planet. The mystery can definitely be solved after entering this APLA. That's my dream.

SECTOR LUNAR A, 06.00 AM AT LUNAR TIME

Yes, the Lunar A sector, a residential area shaped like a yellow capsule. Designed with a very sophisticated architecture and neatly arranged along a steel-designed highway. One by one pass anti-gravity vehicles on the highway. The sky is blue and the cumullus clouds are scattered over the Lunar A sector. There is also a sun shining in the blue sky. Looks like the circumstances on earth. Great is not it? Yet this is the month.

This can be done because there is an advanced tool that makes the atmosphere into daylight like on earth. It changes a circular object along the moon sky. It can be said that a round fencing tool is shaped like a ring. So it can be arranged like a planetarium based on the time of the moon taken like on earth so that the inhabitants of this four hundred year period can feel how the state of the day on earth. Like day and night. Then there are some special officers to control the change of atmosphere based on time. So the special officer can change the tool like the dome into a night or day. Of course it's just the engineering of a high-level hologram projector that scientists have been able to create for four hundred years.

I came out of my house in the shape of this capsule. I'm putting up my artistic design shoes. Then I reach for the very long two-stringed bag that my grandmother Tsunade had given me. Then I put the small bag on my waist. I was ready with APLA's special uniform that was yellow jacket uniform and trousers that narrowed down. I smiled broadly at the hologram of this bright blue sky.

"Time for action now," I say excitedly.

I turned my face in the direction of the house.

"Grandma, I'm leaving now."

My grandmother's voice was heard from inside.

"Yes, go there.

That's my grandmother's answer. He always said that did not make me happy to hear it. But, that's how grandma is. He is well known as a fierce, temperamental lady rough and also dangerous.

Why dangerous? Yes, he can destroy anything if he is angry. Sometimes it makes the lives of others disappear. In fact, I almost went to the hospital just because I did not want to go to school at that time. My grandmother went berserk and wanted to blow me all out. But, luckily there Jiraiya is my grandfather who saved me from the brutal action of a grandmother who is considered terrible.

Thinking about it, it makes me sigh heavy. At least I'm grateful I'm alive till now.

Oh yes, I have to leave right now. The lessons at APLA start at 7:30 this morning.

Immediately I ran down the street of the Lunar A sector, where I live on the moon.

.

AKADEMI PILOT OUTSIDE ANGKASA (APLA), 07.30 AM AT LUNAR TIME

I've entered my classroom in a classroom called Yellow A. Hm, a strange class name.

APLA is equivalent to SMA. Education is lived for three years. But why is the class name not class 10 or grade 1? Precisely the name of the class Yellow A.

Apparently in APLA, each class will be named with the name of the color. Then each class is filled by twelve people. That applies to newly admitted students. The class name for a new student named Yellow.

Then in the second year, the students are going up to the middle class then going into a class named Blue. After that, in the next level will enter a class called Red.

It's weird. That's the class division system applied in APLA. I do not know what that means. However, I will definitely know as well.

Now that the lesson starts, I sit at the front with new friends who come into this Yellow A class.

Yellow A class is a circular design like an egg. Behind the class there is a very tall clear glass window about 15 meters high. Then seen from the high ceiling of this class about 30 meters and equipped with several large headlights that resemble the head of a flashlight. In front of the class there is a digital whiteboard floating in the air. Clear floors like glass. The walls are also clear because they are made of shiny and strong steel. Then the furniture that fills this classroom is a long table and chairs for students and teachers.

Currently stands a teacher in front of the class. He is a silver-haired man wearing a kind of mask but artistically designed. She was wearing the same yellow uniform as us. But, design a different style.

In the teacher's right hand, hold an object as big as a playing card. Above the hole it pops up a screen of digital projectors floating in the air. He kept paying attention to the screen of the thing called 'Pocket Book' it. Sometimes he laughs alone while he continues to teach. We were amazed to see it that way.

"All right, new students, welcome to APLA!" the teacher shouted loudly. "For today's lesson in our beloved Yellow A class, I want to start an introduction first."

Everyone was seriously watching the teacher standing in front of the class.

"Okay, my name is Hatake Kakashi, I'm from Lunar Sector A. I like a lot of things that I do not like is not there I am your guardian and will also guide you during this Yellow A class."

The teacher named Kakashi then glanced at his Pocket Book screen again. He laughed again. Make us sweatdrop again see it.

'What the hell did the teacher read?' I wondered inwardly.

Kakashi then looked at his students again.

"Okay, I've introduced who I am, so it's your turn to introduce yourself in front of this class."

Everyone looked at each other and looked faint. I also prepare myself not to be nervous while in front of the class while introducing myself.

Starting from the left is the group of men. The first person to advance was a brown haired man and brown eyed.

I gasped when I saw the man standing in front of this class. Is it? The person in the hall with the orange-haired girl tied up the twintail.

"Good morning, my name is Hyodo Issei, I'm from the Mars B sector. Greetings know everything," the man named Issei bowed.

The three girls among the six girls who were in the class, cheering harshly calling her.

"ISSEI!"

"ISSEI, I LOVE YOU SO MUCH!"

"ISSEI, LIVE ISSEI!"

Everything becomes sweatdrop see the third action of Issei's impromptu fansgirl. Issei just laughed blandly to respond.

"Are you Martian?" asked Kakashi who was sitting on his own bench.

Issei turned to Kakashi.

"Right, Kakashi's teacher," Issei replied with a big laugh.

"What's your reason for coming here?"

"Ka-because ... Because what is it?"

Issei thought for a moment. Kakashi waited patiently for Issei's answer.

"For fun, teacher."

SIIIIING!

Silence. For a moment all silence with a speechless face.

Disastrous. Log in to ALPA just for fun? A very honest reason for this man named Issei.

"You're honest."

Kakashi looks showing a friendly face indicating he was smiling.

Issei just chuckled at him.

"All right, please sit back to your place."

"Yes, teacher."

Issei walked to the bench next to my bench. I turned around as Issei was sitting on his bench.

"Hey, your name Issei huh?"

Issei turned to me.

"Yes."

I held out my hand. Issei replied.

"Recommend my name Uzumaki Naruto."

"I'm Hyoud Issei."

We both smile together. Glad to get acquainted with new friends.

"Next!" Kakashi exclaimed.

Go for a long-haired red-haired girl with emerald green eyes. He was very excited.

"KONICHIWA, EVERYTHING!"

The girl screamed loudly as she clenched her fist into the air. Makes it all excited as well to answer the greeting.

"KONICHIWA ALSO!"

Then the girl bowed her half.

"Recommend my name is Gremory Rias, I come from the Mars Sector B. It's nice to meet all of you."

The girl straightened herself up again. Kakashi also asked something to this girl named Rias.

"Are you Martians, too?"

"Yes, teacher."

The girl smiled sweetly. Anyone who sees it will faint see it. Including me too.

"Why did you come here?"

"The reason I want to get in here is that I want to be with Issei I LOVE YOU, ISSEI!"

The girl winked at Issei.

GEDUBRAK!

Successful Issei tumbled out of his seat because of Rias's death blip. Everything becomes sweatdrop again.

Kakashi tapped his forehead.

"A strange reason."

"Teacher, can I sit in my place?"

"Yes, please, fine, next."

After Rias returns to its place. Run for a black-haired girl tied with a ponytail and black eyed.

The girl is showing her sweet smile for her friends who are watching her.

"My name is Himejima Akeno, from Mars B sector. Greetings everyone."

Only then did he bow. After the girl named Akeno was straightened up again. Kakashi asked him.

"Oh, the Martians again apparently."

"Yes, teacher."

"What's your reason for getting into this APLA?"

Akeno glanced in the other direction. Precisely toward Issei who was sitting on his stool again.

"Because I want to be his dear Issei's girlfriend."

GEDUBRAAAK!

Issei's back dropped from his chair. Make it all sweatdrop again.

Kakashi tapped his forehead again. She put on her crumpled face.

"Huh, the reason is weird, it's because guy, Ok, back to your place."

"Okay, teacher."

"Next."

Akeno continues to smile until it returns to its place. Until then another girl.

The girl immediately bowed. This time the orange-haired girl was tied twintail.

"My name is Shidou Irina, from Mars B. Salam know."

Back Kakashi asked him like the previous students.

"Marars again, what's your reason for coming here?"

Irina holds her mouth to put up a thoughtful pose.

"My reason is simple, teacher."

"Oh yes, what is that?"

"The reason is that I also want to be close to Issei."

GEDUBRAAK!

For the third time Issei fell from his seat. Everything is sweatdrop again.

Kakashi put on a blank face.

"Uuuh, why many girls now put love first before school?"

"So there's another question, teacher?"

"No, get back to your place."

"All right, teacher."

Irina returns to her place. Then came a blond and blue-eyed man. Has a beautiful face and a smile continues to stick in his face.

"Hello everyone, introduce my name to Yuuto Kiba, I come from the Mars sector C. The reason I came here is to become a space pilot and also become an expert in assembling spaceships."

"Oh, there's something serious about it, you've explained it all before I asked," said Kakashi smiling.

"Yes, teacher, so the teacher does not have to bother to ask me the question again."

"Hehehe, good, good, ok, back to your place."

"Okay, teacher."

Kiba returns to his place. Followed by a man with red hair and green eyes. There was a dark circle around her eyes that looked wistful.

"I'm Sabaku No Gaara, I'm from the Lunar sector B. The reason I'm here is to be a space pilot."

Gaara spoke with a flat face. Makes it all amazed to see it.

'Son of the month huh? The Lunar B sector? ' I was staring intently at the man with the flat face.

"Next."

Gaara returns to his place. Go for a man with black hair and tie one like a pineapple. He stood in front of the class with a long yawn with a bored look.

"Hoaaaaaam, good morning I'm Nara Shikamaru From the Lunar sector H. The reason I came here was to be a space pilot just because my parents forced me."

Make everyone speehless see it. Kakashi just stared at Shikamaru who kept yawning long in one second interval.

'The period of people like this who will become a space pilot later? Can-can plane will collision dong, 'I thought again in my heart.

"Next."

A short gray haired girl with golden yellow eyes. He stood stiffly with his flat face.

"My name is Koneko Tojou from Mars B. My reason is to be a space pilot Thank you."

After that, he goes off before Kakashi invites him to return to his place.

"Next."

A short, green-eyed short-haired girl was bowing her half.

"My name is Haruno Sakura, I'm from the Lunar E sector. I want to be a space pilot, it's nice to meet all of you."

Girl shows her smile after straightening her body. Then he immediately left after Kakashi invited him back into place.

Then a long indigo-haired girl tied up two forward ones. She's the last girl.

"Congrats in the morning, sa-my H-Hyuga Hinata, from the Lunar F. Salam sector knows everything."

The girl leaned nervously. I take it seriously. It was the girl I'd crashed at the moment in the hall.

'Apparently we meet again apparently,' I wondered.

After the girl named Hinata was advanced. Then move on, my best friend Uciha Sasuke who is also my classmate.

"My name is Uciha Sasuke from the Lunar G sector. My reason for coming here is to become a great space pilot and defeat my friend Uzumaki Naruto."

I was struck by the direct narrative from Sasuke just now. I saw Sasuke staring at me. He threw a smile at his knot. I also smiled to see it.

"Wow, that's a great excuse," Kakashi said, folding his arms across his chest. "You're from the Uciha clan?"

Sasuke looked at Kakashi coolly.

"Yes, Kakashi's teacher."

Kakashi stared at Sasuke. Then he smiled.

"All right, last."

Sasuke walked to his bench. I walked across him. He glanced at me. I also glanced at it.

"Good luck, Dobe!"

Sasuke patted my shoulder gently. I smiled at him.

"Yes."

Then move me with a solid feeling of being supported by Sasuke. I walked with a daring mixture of nerves. Very weird. Whereas once in the School of Space Flight, I will not be this nervous when will appear in front of the possibility. Perhaps this is the first time I've stood in front of a classroom where the most sophisticated inter-planetary school in the solar system.

Now I'm standing in front of the class. Everyone was looking at me seriously. I set my breath briefly. Then exhale slowly. I should not be nervous because this is the most phenomenal class for me. This is my first day at APLA. Academy that will bring me closer to my dreams.

Quickly, I bowed my body.

"Good morning everyone, my name is Uzumaki Naruto I'm from the Lunar sector A. The reason I'm coming here is to be a space pilot and ..."

I straightened up my body and interrupted my interrupted words.

"And I want to do an expedition to the Black Planet to find the whereabouts of the lost former people and uncover the mystery of the cause of the Earth being the Black Planet."

My loud and echoing words in the class made everything widen his eyes. They do not believe what I say. They look shocked to hear it.

I grinned broadly while pointing my thumb at Sasuke looking at me. I saw Sasuke round his eyes. He must be shocked by what I said earlier.

"Uzumaki Naruto."

Kakashi called me. I turned to him.

"Come on, come with me to the teachers' room right now."

I widen my eyes. Did my honest speech make Kakashi's teacher angry? I saw Kakashi looking at me seriously. Her eyes narrowed sharply.

"Yes, teacher."

Kakashi walked out of the class first. I followed him from behind. Really, this confuses me.

A / N:

Thank you for reading this third crossover story. Crossover Naruto and High School DxD.

I translated this fic into english and republish it here. Sorry, if the translation is a mess.
