Exiakaiser: Hello and welcome to my first ever crossover with High School DxD, "Vengeance". In this story, my first in this series, the Occult Research Club faces a series of strange murders, as well as a startling revelation, as a legend becomes fact, and a survivor of a lost Devil house appears. This story takes place immediately after the final battle with Raynare, the Fallen Angel that killed Issei in the first act. And it all starts with the deaths of several Fallen Angels and Stray Devils.

To that end, I decided to make this story a little more mature to keep up with the original content (Leave it to Exiakaiser Productions to keep it in line with the original content, as usual).

However, the battles are more intense, with the new character, appearing no later than the second half of the first episode.

Name: Hlaisen Alatreonus Kirin

Age: 20 years (Age of death: 18 years)

Gender: Male

Physical appearance: Blonde hair, short, spiky and well kept. Blue eyes with a more bestial pupil. Body is covered in a strange black metallic armor and hands end in claws. Armor has a strange gold accent. Accent are actually energy lines that allow him to access his Sacred Gear's special power. Wears only black.

Personality: Kind, yet when angered, is more vicious. When he is serious, his body will emit a fiery aura. Can boost his aura at will.

History: Hlaisen was part of House Kirin for a couple years after his death. Then Lord Riser Phoenix came calling on Lady Kirin (Hlaisen's master, and the only one to show him any compassion), and the two houses fought in a Rating's War. Hlaisen made himself recognized for his powerful rage and battle prowess. However, it was all for naught, as Riser destroyed the House's entire forces, save for Lady Kirin, and a Zetton-fused Hlaisen. However, try as he might, Hlaisen still lost, and Lady Kirin resigned.

3 Days later, during the engagement party for Riser and his beautiful bride, Hlaisen crashed the party with terrible news- all the men of House Kirin were slaughtered and only he survived. It was said that Fallen Angels had slain them all, but Hlaisen has evidence that House Phoenix had committed the crime. However, instead of trying to rescue his lady, Hlaisen said he will accept exile to the human world. However, before he left, he pointed at Riser and foretold his return 'When the Red Dragon Emperor Rises in the House of Crimson Haired Devils.' However, before he was able to leave, Hlaisen was struck down and left for dead…

Or so Riser thought. At the last second, Hlaisen had activated the Baltan ability, allowing his body to escape unharmed in place of a dummy. However, he was officially labeled dead.

Sacred Gear: Monster's Graveyard (Specially designed armor that enhances the wearers ability with that of an Ultra Kaiju.)

Effects: Monster's Graveyard has 10 passive abilities (Always active), and 10 active abilities. He can choose these abilities at will, and can even release more should he need to increase his power. There are 12 levels, each based on the several types of monsters.

We will explore the full extent of his powers as the story progresses. So, let's get this show on the road already. All Kaiju and Seijin are explained in the story in Italics.

And now, we regrettably now have to talk about something that still makes me angry it even exists- Attack on Titan. They just announced this via Funimation and the anime news network. Eren Yager Fanboys, rejoice- season 2 has been confirmed for later this year. I, personally, only like the series for its technology and world, but to me, the characters are one-sided, and the monsters seem like parodies of the twin gargantuans from the old Toho film War of the Gargantuans. It's about two giant humanoid monsters who fight over the people. One is trying to protect them, while the other is killing them. Sound familiar. Plus, I just finished volume 16 of the manga. Took too long to explain the backstory of the world itself, as well as the reason why the titans were killing people in the first place. Now I know why this series is so popular- it's a overrated drama. Why is it that this series is so popular even though it's about as bad, if not worse than an episode of Jerry Springer or Maury? If you have a reason, without being a fanboy comment (I.e. 'It's awesome'), comment. I would love to hear the explanation. If someone can explain the reason well enough, without going total fanboy/fangirl over the series, I will not only do a fanfiction, but create a character for that world, as well as a new system for killing titans.

DISCLAIMER! I only own Hlaisen's original design and nothing more. The Ultra Kaiju, Seijin, and the like are all owned by Tsubaraya Productions, and High School DxD is owned by Ichiei Ishibumi and licensed by Funimation. So, let's get this show on the road.

WARNING! This story is meant for teen and older. Viewer discretion is highly advised.

"What the hell," said Issei, confused by the sight he was witnessing. Before him was a dead devil, exactly like the one they were sent to dispose of. However, it had a series of slash marks on its body, like a giant beast had laid into it.

"I'm surprised," said Akeno, smiling gently, "Someone managed to beat us to it. Any ideas as to who it could have been, Rias?"

"I don't," said Rias, hand on her chin, "Proceed with caution. The culprit will probably still be here."

The group then split up and Issei wandered off on his own. "What kinda monster could have done that," he asked. "That kinda viciousness was off the scale."

However, as he turned a corner, he saw a strange creature slashing at the wall in front. It was looking away, so Issei could not get a good look at it. "You seem strange," it said, continuing his work while looking away. "You smell of fire, but not of Phoenix. Your scent is similar to Lady Rias Gremory." The strange creature then turned around, and Issei got a good look at it. It looked like an armored warrior in black armor, but along certain places, golden lines seemed to stick out like bones. However, Issei then realized they were where the bones in a human body were. "I wish to test your resolve."

"Hey, man," said Issei, backing off, "I only was here to kill a stray devil. Whoever you are, I'm sure you wouldn't kill someone without reason, right?"

"Hmmmm," said the creature, thinking, "I told you I wanted to test your resolve, but you backed away. Mayhaps I scared you?"

"What the fuck," asked Issei, struck in his pride as a man, "I am not. I just see no need to fight you."

"ISSEI," yelled out Rias, coming around the corner. Then she saw the creature and thought, "That form. It couldn't be…"

"Too soon," said the creature, jumping into the air. "I will leave you be for the time being. We will meet again, House Gremory.

Then he disappeared in a flash. However, when Rias looked at the wall, what she saw upset her. On the wall was a single message, "THE TIME HAS COME! HOUSE KIRIN RISES AGAIN!"

"It can't be" though Rias, "It just can't be!"

High School DxD!

Vengeance!

Episode 1!

From Darkness He Came!

-Next Day-

-After School-

"What the Fuck is House Kirin," asked Issei, asking the obvious question. A day had past since the attack, and Issei was trying to process the information from last night. "And who the hell was that?"

"A good question," said Kiba, "I never heard of that house before. Who were they? And what does it mean to 'Rise Again'?"

"The story of House Kirin," said Akeno, frowning, "Is one of the saddest legends of Devil-kind."

"A few years back," said Rias, "Long before I sired you into our house, there was a strong house among Devils. It was called House Kirin, and the lady of the House was a beautiful woman, strong and kind. Her strongest servant was a Pawn named Hlaisen. She loved him more than the others because he was just like her- strong and kind.

"However, the House lost to one of the other houses. Shortly thereafter, all but one male was slaughtered by Fallen Angels. At the engagement party, Hlaisen, the only survivor, accused the house of treasonous murder, and told him 'When the Red Dragon Emperor rises in the house of the Lord of Devils, he would return and the Rebirth of House Kirin would be assured. He was thought dead for his trouble."

"Nice retelling," said a voice. Everyone turned around…

…To see a young man in black clothes sipping one of the cups of tea. "Lovely taste, and beautiful aroma," he then said, setting t back perfectly on the saucer it came from. "However, you got it half correct."

All of a sudden, Kiba and Issei attacked…Only to get smacked back. "I didn't come back to fight you, House of Gremory. I came only to talk."

"Who are you," asked Rias, angered by this strange intruder, "And what do you want here?"

"It's been a year, Lady Rias," said the stranger, standing up, "Surely you haven't forgotten me already. I am the man you just spoke about."

"I-i-impossible," said Issei, taken aback. "You said he was killed."

"Shall I show you," said the stranger, turning away for a second, "You, knight, I need you to stab me right in the chest."

Kiba rushed the stranger in black with his blade drawn, stabbing the man right square in the chest. The guy fell, but no blood flowed.

Issei stood there, confused. Then a hand fell on his shoulder, and the stranger stood right next to him. "Monster's Graveyard Special effect Level 3-18P (1)," he then said, "Baltan Body Molt. This ability allows me to escape death once every few minutes. It hurts like a sonofabitch, in addition. However, if I use it more than 20 times, my body starts to suffer far worse pain."

Baltan Alien- first encountered by the Science Patrol in the 1960's this race of microscopic aliens attempted to invade Earth. However, they were beaten back by Ultraman, whose powerful finishing attack used their one weakness- Spacium, a powerful element. They also had the ability to split off from an existent body in a brand new one in 1.5 seconds before their death. Their sonic cutter beam is formidable.

"It can't be," said Rias, stunned, "Such an ability belonged to only one man."

"That's right," said the figure, "My name is Hlaisen Alatreonus Kirin, Pawn formerly in the service of House Kirin. For those of you who haven't met me yet, hello and greetings."

"Charming," said Kiba, "What do you want?"

"Like I said," said Hlaisen, sitting back down and pulling out a hard candy and popping it into his mouth, "I only wish to talk. To correct you, Lady Gremory, It wasn't a group of Fallen Angels per say. It was a group of Devils disguised as them. The House we lost to was run by a man who only had female servants. So to him, men were a threat. He summoned all the men of House Kirin to a meeting. However, I couldn't make it, due to the fact that I had somehow contracted a cold, despite being a devil myself.

"I found out a day after the fact. I had hidden myself using Mephilasian's illusion skill, creating one over the door. After 24 hours, the deed was done, and I only was able to find out what happened because of security footage. Apparently, it was all a trap lured to kill us. Before I could leave however, I was set upon by a straggler, who told me that I shouldn't have survived, that by dying, I served a greater purpose. This just pissed me off, causing me to go Ace Killer on her ass…

Ace Killer- An artificial Monster created by the Interdimensional Choju Yappool in an attempt to finish off Ultraman Ace. However, despite coming close, Ace Killer was defeated by Ace using the power of his brethren. His armored hide was strong enough to withstand heavy damage. His talons could pierce steel. His abilities include the power to absorb other people's abilities, making him a formidable foe indeed.

"Afterwards, I ran to the engagement party, only to get stopped by some guards, whom I gave a good thrashing. I then reported to my lady that all the men were dead, and then accused the Lord of the heinous crime. However, he just laughed at my accusations and told his men to escort me out of there. However, I beat three and said, 'Hear my words for they mean your doom! On the day the Red Dragon Emperor appears in the house of the fiery-haired Devils, I will return to restore Hose Kirin to its former glory!' This angered the Lord, who had me killed…Or so he thought. I, at the last minute activated Baltan Body Molt and Mephilasian's Illusion Abilities, allowing me to escape undamaged. I heard the wedding was lovely, and Lady Kirin is still living under his thumb?"

"Yes," said Rias, "She is. Why do you ask?"

She then saw tears running down Hlaisen's cheek. "Dammit, my beloved," he then said, "Why do you still serve that damned chicken? WHY DO YOU ALLOW HIM TO CONTINUE ON LIKE SUCH?"

-Later that evening-

Issei was asked to house Hlaisen till the next day. "I feel sorry for you," said Issei, to Hlaisen, "You seem like a good guy, but to suffer such pain, how do you cope?"

"It's not easy," said Hlaisen, sitting up. "I know what my purpose for surviving is, though."

"What is it," asked Issei.

"To avenge my brothers in arms," said Hlaisen, snarling at the same time, "To kill those who hurt me, and the man behind them. A man who generates a fiery aura."

"You sure sound less like you were spoken of," said Issei, confused.

"I used to be like her," said Hlaisen, "Like Lady Kirin- Kind and strong. I grew to learn that vengeance can be a powerful motivator to complete a mission."

"What was it like," asked Issei.

"Excuse me," asked Hlaisen.

"To grab her melons everyday," asked Issei, drooling in a perverted way. "To be so close to her naked body, and enjoy such beauty?"

"W-W-WHAT THE HELL MAN," said Hlaisen, getting really flustered, "J-J-JUST BECAUSE I WAS HER LOVER THAT DOESN'T MEAN I AM AS PERVERTED AS YOU! SOME OF US HAVE STANDARDS, DAMMIT TO HELL!"

"Sorry I asked," said Issei, realizing that Hlaisen was not the same as him.

"To be perfectly fair, though," said Hlaisen, "If you were around her, you would understand why I loved her like I did."

"Why is that," asked Issei, turning around.

"There aren't many women like her in the universe," said Hlaisen, remembering her. "She saved me after my mother was killed by an angry mob. I was dying in a ravine, attacked by a Fallen Angel, much like you were, and bleeding out. However, because of my nature, I was able to climb out of the ravine, and that is when I met her. A woman with hair black as night, and skin that made her look like she was made of silver. She asked me if I would like to live on. However, I didn't realize she was a devil till after I was brought back to life."

-Next Day-

-After School-

-Old School Building-

"You cannot be serious," said Rias, annoyed, "You want join our House till your mission is complete?"

"That's what I said," said Hlaisen, bowing. "Afterwards, I would forever be in the debt of this House. In turn, I would serve as you see fit. Be it soldier, wish-granter, or even the scum who cleans the shit-house."

"I get the point," said Rias, "What I don't get is why. You already belong to a House."

"That house was destroyed by that damned fried turkey," said Hlaisen in anger. "My only mission is to make him pay for his foolish actions. Listen, I know you used all your pawns to bring Issei the Pervert into your group. I also know you have no room for a man of my placing. However, I only wish to join temporarily. Should I complete my mission, you could choose to sever ties with me as soon as possible, and get your 'Issei Time' going again. Or you could also have me complete impossible tasks as well. At the same time, should I die in combat, that also nulls the deal. It's your call, but I wouldn't waste the chance to gain an additional warrior in your service. Plus, the benefits of me being on your side far outweigh the risks."

"Benefits," asked Rias, intrigued.

"I am a seasoned combatant," said Hlaisen, "Trained in battle for 2 years, and able to teach others how to fight. I could mentor Issei on how to use his Sacred Gear in a way that could change your fate. In addition, I have been called the 'Genius Pawn', using my skills in such a way that, in a battle of numbers, all you gotta do is follow a plan I set up, and it won't fail, unless there is a game-changer on the opponent's side. And on top of that, you wouldn't have to worry about healing me. If fatally wounded, I can always use my Baltan effect, and molt."

"I see," said Kiba, nodding, "He is proving his point."

"Very well," said Rias, standing up, "But I gotta ask if you are the real deal. Do you still have your familiar?"

All of a sudden, Hlaisen remembered, "Yes. Like me, he was unable to be killed by the House. Come forth, my friend!" All of a sudden, a Baltan Alien appeared on Hlaisen's right shoulder. "This is my familiar, Baltan Seijin Jr."

"Ah, stuff it," said Baltan Jr., getting snarky, "When are we gonna get revenge?"

"Soon enough," said Hlaisen, as Baltan Seijin Jr disappeared. "Now, I say again, Lady Rias, will you let me into your fold, if only till my task is complete?"

Rias thought for about 3 minutes, weighing her options, and then asked, "Do you remember the Oath of Mercenaries?"

"Yes," said Hlaisen, "I even have a contract in case you need to sign it." With that, he pulled out a scroll and a pen.

"Do you also have your evil piece," asked Rias.

Hlaisen thought for a second, and then took off his shirt. He then reached his hand into his own chest and dug it out. "Dammit," said Hlaisen, after pulling it out, "I forgot how much that fuckin' hurts."

"Very well," said Rias, taking it, "I accept your proposal. "How do we do this?"

"I can give up my place as a pawn to temporarily fill a single piece…for a time."

Rias then created a magic circle around the pair of them. She then said, reciting the Master's half of the Oath of Mercenaries, "I am the master of your sword. Till death takes you, Thou hast no place other than my House. You will fight for my cause, and you will die for my cause. You will not leave my service unless I release you from your contract, or death takes you. Your hand is mine to command, your every action decided for me. You missions will serve me, and my goal."

Hlaisen replied, "I am the Servant of the Sword, unable to question. My blade is yours to command, my actions decided by you. I will fight for your cause, and will gladly lay down my life for it. I will not do anything to embarrass the House I serve, and will not leave unless my Master releases me from service, or death takes me into her cold embrace."

"Rise," said Rias, releasing the circle, "Pawn of Gremory."

"Pawn," asked Hlaisen, "But I thought you sacrificed all 8 of your pawns to make Issei a Devil."

"Your piece is a Pawn," said Akeno, "So therefore you were made a pawn again."

Hlaisen sighed and said, "Very well. I accept this as a test."

-Next Time-

Hlaisen begins training Issei how to properly fight. However, a new stray appears, and it is Hlaisen's turn to show off. In the glow of the full moon, can Hlaisen prove his worth on the field of battle? Next Time:

-Nightmarish Ace Killer-

Well, another story started…What's with all the new ideas being crafted all of a sudden? I must be generating more ideas left and right. Ah Mou!

Anyway, let me know what you think in the review section.
