Hey there! It`s been a while, hasn`t it?! :D Finally after three long months and half of being absent, I am able to live my activity a bit. So yeah, it`s another story from me for which I decided to use the anime Akame ga Kill and High School DxD. Yeah… another crossover. I know some may be sick of my other one "Reborn as a Campione", but I had this idea since three weeks now without managing to start it. The truth is that right now I am out of ideas for both my two first stories, so I thought of starting this one having lot of ideas and stuff.

The main character of this fanfic will be Tatsumi, who after dying meets The Great Red dragon, who sends him in Hs DxD world. There he will start living a life as demon, helping his friends out and fighting for them. There most certainly will be someone to be paired with him, which for now lean to Akeno, Xenovia or Rias. But maybe there will be a harem for him too, just like in the series that he comes from so I`m not going to give it all just yet, so don`t hate me.

So I hope you like my new little project. Feedbacks are welcomed, critiques as well, but please no HATE. If someone wants to comment just to spread hate and start conflict, then he/she better leave if they don`t like anything, since I`m not forcing anyone to against his/her will.

ENJOY!

Chapter 1 - Start of the second life

There laid the dead body of the brown-haired boy, who just gave his life to protect the citizens of the capital from the falling Emperor`s teigo, by stopping it with his last strength. Now wrapped in Akame`s arms, one of his precious friends with whom he fought to change the unfair country in which they lived. His heart seemed to have stopped and now the teen waited for the long reunion with his fallen friends – Sayo, Ieyasu, Sheele, Bulat, Chelsea, Lubbock, Susanno and Mine. It looked like a wonderful place to spend eternality, without any concept of time. However, no matter how much he waited that did not happen nor seemed what will anytime soon. The boy started wondering what is going on.

"Am I really dead?" Tatsumi said to himself. "It feels like I am still a step away from eternal peace. But what could be possible holding me?"

Suddenly, his eyes felt the heavy need to open once more and he didn`t have any control at all. It seemed like his eyes weren`t his, but of someone else.

"I guess I still don`t want to die. There were many things that I wanted to do." He tried answering the question himself. Honestly, how helpless can I …" He tried to say something when some kind of creature appeared before him. The blurry effect he head in the beginning slowly started to fade away, cleaning the image in front of him.

Just like that. the boy focused his vision on the creature and first didn`t believe what he was seeing. Right before him stood a big, red dragon with huge wings and a horn on his forehead. It looked really frightening and strong. The two big eyes it had stared directly at Night Raid`s member as if he would either eat or hypnotize him. Tatsumi was left stunned without knowing what to do, because of the reason that he had never seen any dragons such as these, even the dragon that Kurome controlled with her Imperial Arm paled before this one. Silence was controlling the entire area around them and it appeared it will stay like that, when it happened. The one thing that the brown-haired boy never expected from a danger beast, it spoke.

"I am 'The Great Red' dragon and this space is my territory." The dragon said with a loud voice.

Tatsumi remained silent, unable nor to do or say something and continued to stare at the beast, amazed by its size and the fact that it actually could talk.

"Tell me human, do you know what this place is?" The Great Red questioned and without waiting for a replay continued. "This is the Dimensional Gap that exists between worlds. A place which unknown to most and is known by few." It stopped for a moment and started talking again. "Here time doesn`t have any value at all, thus whoever is trapped in it doesn`t age or doesn`t change."

"Why I am seeing this place when I am supposed to be dead?" The boy asked with a calm voice, not taking an eye from the giant beast.

"You are dead, but that is only in the world from which you come from." The dragon explained and stopped for a while. "Human, now I will ask you a question and it is up to you to answer honestly. What happens next depends on your answer alone." Tatsumi nodded, letting out a sign of understanding and the dragon saw that. "Do you truly wish to die or to live instead?"

Even after preparing himself for the worst, the question caught the boy off guard, forcing him to sink into a deep thought going through it over and over, being careful not to answer wrong. He moved his eyes from the dragon and bowed his head down, staring at the endless space beneath them. The silence in the atmosphere made it completely look like the time has stopped as neither the boy or The Great Red moved a muscle. That was until Tatsumi lifted his head with a look in his eyes that show his determination to answer.

"I don`t want to die yet. I still want to live." He said and looked straight at the creature in front of him.

"Good answer, human. Go now and live then!" By saying that, the dragon roared with all its might and flames started covering the entire space, until the boy fully vanished in them. However, no pain came from that and instead the teen felt his consciousness fading away.

Everything went black in front of him with the feeling that his body and mind separated and no longer could reunite. The fear of the unknown started taking over him with every second as he started wondering where he will be taken and what he is supposed to do there.

All of a sudden, his eyes shot wide open and he saw the sun, which was shining right in the boy`s face, forcing him to get up in a sitting position as quick as possible. After taking sit on what seemed to be the ground, he took a look in every possible direction in order to check the area. Strangely looking buildings were surrounding him almost from every side, some kind of transport with four wheels, which moved in fairly high speed for what he had seen before. Night Raid`s member remained unmoving for quite awhile, only staring at everything he saw, when he decided to get up and start walking with the idea to find more about where and what kind is this place. When Tatsumi did so, he blinked few times in surprise to his cloths untouched and clean as if nothing really happened back when fighting the Emperor`s Imperial Arm.

Walking through the streets, the brown-haired teen continued to see more and more new things that were out of his knowledge, but what left biggest impression was that the people he crossed paths dressed way beyond his understanding and seemed truly happy. It was something that the assassin noticed right away and compared it to the life of the people in his world, who pretended to be happy, but deep inside they were always wary of the rest, fearing that death could reach them in the blink of an eye. However, here he couldn`t fell even the slightest sign of fear and despair in the passing people. No one seemed to pay attention to the boy, neither looked cautious of him and the sign of alert couldn`t be sensed anywhere, which made him to drop his guard and walk more freely around.

Time passed so fast that the green-eyed teen didn`t even realized when the sun has set in the distance horizon and the moon rose high above in the sky. The streets becoming less lively as most of the humans appeared to have gone back home. Strong wind started blowing from the east, which sent a cold chill down Tatsumi`s spine, marking the occurrence of night. He got the idea and started walking a little bit faster in order to find a shelter for the night. In less than ten minutes, Night Raid`s member found himself standing in front of a fountain in what some park. It had a circle form, but it wasn`t that big, the water fell from somewhere like four meters. There he spotted a young woman and a young man standing next to it and talking to each other, who the assassin thought that they must be a couple or perhaps husband and a wife. Not paying attention to them, the teen went to the fountain and bowing his head down, he took a look at his reflection in the crystal clear water. Time seemed like it stopped as a deep silence moved in when the sound of of footsteps ringed in his ears, making him lift his head.

Turning around, the boy saw a person around his age, or at least that was what he thought, coming at his direction and that of the two people near him. The man wore a dark blue coat, under which he had a white skirt, continued by blue jeans and black shoes, and cross that was hanged on his neck. He had white-short hair and red eyes and insane smile on his face.

"What do we have here, a lone boy and a couple in the park at this time at night." The person spoke with a laughing tone attached to his voice. "Didn`t your parents tell you not to do that, otherwise you may meet some bad people." Finishing, he took out a strange sword and stood threatening before the humans.

'What is this guy?' Tatsumi asked in his mind.

Seeing the weapons, the woman gasped in panic and hurried to hide behind her lover. Noticing that, the white-haired boy decided to go for the lone target and dashed at the assassin, who didn`t have time to do anything else than dodge by jumping to the left, after which he rolled backwards few meters, creating a safe distance between them. This in turn made the attacker to turn towards the couple and attacked the man by swinging with his sword again, aiming straight for the target`s head. Fortunately, the latter was able to escape by leaning backwards, while falling on the ground on top of the woman, after which he rolled to the left, but sadly his lover found herself facing the dangerous boy. Further it appeared that the white-haired teen didn`t mind changing his prey and aimed his sword down at the human, threatening to pierce her heart.

Blood splashed on the ground as it started creating a big puddle, which expanded by the second as it all looked like the attacker stroke down his target, except for the fact that it wasn`t the female, who was stabbed, but the green-eyed teen. Just before the woman was struck dead, Tatsumi jumped before the falling weapon and used his body to shield the unknown person behind him. The couple stood in shock and just watched as how someone, who`s a complete stranger to them, was willing to go this far.

"Take her and run from here." The brown-haired male said, turning towards the man. "Now!" He added by shouting.

"Thank you!" The latter thanked, after which he went next to the woman, picked her up and together they ran in the darkness of the park.

"What a touching scene? You sacrificed yourself to let them escape." The white-haired boy spoke up with a mocking tone.

However, the former assassin didn`t reply with words and instead gave the opponent a quick and strong head butt, which forced the man two meters back as he pulled the sword out of the other boy`s body. More blood escape from the whole in the green-eyed male`s body, but this didn`t even seem to bother him at slightest. What troubled him was the fact that there was a dangerous foe against him, who was obviously planning on killing someone tonight, regardless of who it was.

Seeing that Tatsumi isn`t going to act soon, the attacker decided to strike first and ran at the boy, starting to swing his sword again and again, aiming it for the target`s head as if he was an executioner, but all of his attempt ended in vain as they were all dodged by the latter. Witnessing that, the unknown boy brought his gun into action as well, shooting after the moving target with the hope to ease his work a little by not moving much. Surprisingly for him, the prey dodged every single one of the bullets with the same ease that he dodged the sword strikes, which angered the attacker and that was way to obvious.

"You are an agile one, aren`t you?" The man commented in a laugher.

'This is bad. The wound that I received from earlier is a little too close to my heart, which without doubt will start to affect on my moves soon enough.' The former member of Night Raid said to himself. 'I better counterattack soon or try to run from him.'

"If an ordinary way won`t work on you, then what do you say we speed up the show a little?" The enemy said and took something out of his pocket and threw it at the ground.

Upon the contact of the object with surface, a bright white light erupted from it as started glowing strongly, forcing the green-eyed teen to use his right hand to cover his eye. The light glowed for the next few minutes and after it finally faded there was literally no signs of the human in front, surprising the boy in the process.

'Where did…' The former assassin tried to analyze the situation, but stopped when a dangerous feeling came from behind as the opponent appeared from the back and prepared to attack once again.

"I got you now." The boy shouted and swung his sword at the target`s back.

Fortunately, Tatsumi sensed the danger beforehand and by making a couple of topples over forward, managed to dodge in the last possible moment, leaving the attacker unsatisfied again as his target just refused to give up and become a dead meat.

"Quite dodging, damn it. I feel frustrated after losing to some shitty devils and I need to let out my anger on someone, so just stop running and let me slice you up already." The attacker said, obviously losing his patience.

"What are you talking about?" Night Raid`s member asked, but was ignored by the enemy.

"Never mind, I just need you to drop dead…" The latter tried to reply, but got cut off when a voice rang through the air.

"Attacking innocent people just, because you are unable to handle your problems. You really are pathetic." The same voice echoed again as the both boys saw a figure coming out of the dark.

It was girl. She had a crimson hair that was long all the way to her thighs and blue eyes. Her attire consisted of a white-long sleeved, button-down shirt with a black ribbon on her shirt collar worn under a black shoulder cape and a matching button-down corset, a magenta skirt with white accents, and a brown dress shoes over white crew-length socks.

"Well, well, it looks like I stumbled on the big fish." The white-haired teen replied as if he knew the woman in front of him.

"I don`t know why are you here, but that`s enough of you terrorizing others." The female said and looked at him threatening.

"Don`t get too cocky, you bitch!" The boy shouted and dashed towards her. "It seems you are alone this time. Now I can easily cut you in two."

However, she didn`t answered and pointed her right hand at the incoming threat. The next second, a strange red light appeared from it and she aimed it at the opponent, sending him couple of meters back, until he hit a nearby tree, breaking it in the progress. The tree fell on the ground and as a result its branches buried the place where he landed, making it like a mountain of wood readied to be lighten up by fire. Silence moved for the next three minutes silence moved in, before the white-haired buy jumped out and began to shot at the girl with his gun again and again. Sadly for him, she deflected every single one of them with such an ease that irritated him by the second.

"I will remember this, you missy." He screamed and took out another flashlight of his jacket and threw it, blinding the area of the commotion.

'It`s over at last.' Tatsumi thought to himself, after which he simply fell on the ground as the pain from the wound started hurting more than earlier. 'I guess it`s a miracle I managed to last this long in this condition.' He commented in his mind, while looking at the place where the attacker was a moment ago.

Suddenly, his eyes caught the picture of what appeared to be the girl`s shoes, making him lift his head in order to take a better look at her. She stood there with a worried expression on her face as she immediately kneeled next to him and started pressing the wound on his body with her hands.

"Are you alright?" She questioned with a carrying voice.

"I have been better." The boy muttered weakly, but still enough to be heard.

"Here, I will help you stand up." The female said and attempted to lift him, but stopped when something made her back a step behind into a standing position. "Do you posses a Sacred Gear." She asked something, but the teen could not understand what could be she talking about.

Tatsumi just stared at her and tried to saturate himself with her looks. That crimson hair, those blue eyes, that figure, they were all incredible to the point that the former assassin thought her as one of the most beautiful women he ever met in his side alongside with beauties such as Akame, Chelsea, Leone, Sheele and Esdeath. Besides that, her aura that flowed around her was that of nice, kind and a generous person, which remained him of his fellow clumsy purple-haired female friend from Night Raid. All of that distracted him from the first thoughts that crossed his mind, which were how he got another chance to live just to find on the blink of death again, not even a day after his new life.

"I will be very thankful if you can accompany me in my last moments." The boy said coughing some blood, while not moving his eyes from the figure of the woman in front of him.

The latter on the hand stood unmoving and was wondering what to do. At first, she thought of calling an ambulance. However, the boy`s last words made her think other that exceeded the human`s methods of treating the wounded and on top of that the feeling that she received just moments ago was itching her from the inside as if she wanted to do something complete else than calling for help.

'There isn`t a much of a choice, so…' She tried to think of an solution when something hit her out of nowhere. 'Wait, I have an rook piece and four pawn pieces that were given back to me after Ise`s evil pieces become two mutation instead of eight.' Saying that, it appeared that she had reached to conclusion as her face became determinate, which the green-eyed teen instantly noticed.

All of a sudden, she kneeled next to him again and just like that a smile formed on her face, followed by her sweet voice. "If you are so willing to thank me and live, then I shall grant your wish." She added and took his head in her hands.

After that, the crimson-haired woman took something out of her left pocket and showed it to the boy. In her hand there were some kind of little figures that were colored in white and after focusing his vision he managed to recognize them as five chess pieces – four pawns and one rook. Just like that, the female putted the rook one back into her pocket, while the others placed on top of the Tatsumi`s body. Next, she stood up just as as a strange red light began to glow in the area around the pieces, including him as well.

"Live for my sake!" The woman said, while still smiling at him.

It was that moment, when the boy`s eyes started to slowly close, until the black picture appeared again. He felt his consciousness fading away, losing concept of what is happening and what will happen next with him and will he live or die. That was the question, which mattered to him the most, putting everything aside.

Waking up again, the assassin blinked twice at the sight or what appeared to be a ceiling of a room. He instantly jumped into a sitting position and decided to make a quick full around in order to check where he is. It turned out that he was indeed in a room with a unknown location to him and without any idea what time it is, only that it must be somewhere in the morning when the sunlight shine in his face. After successfully calming down, the teen let a sigh of relief of the thought that he must be alive and it was than when he found the fact that he was bare naked sitting on a bed. Seeing this, the former assassin started looking for his cloths, but no matter where he looked, there was no sign of them, but managed to spot a blanket next to him. Grabbing it with his right hand, the boy pulled it to wrap himself in it, but as soon as he did so, the view of pair of two soft, big breasts popped right before him. And on top of that, it turned out that they belonged to none other, but the crimson-haired girl, who saved him yesterday.

As if feeling his eyes staring at her, she slowly opened her one and with a sleepy face and after wiping the sleepiness from her eyes, she started looking around when her attention was stopped on the naked boy.

"Good morning!" She greeted with a smile.

"G-Good morning!" He replied, still being surprise about why is he seeing this girl fully naked, without even knowing her. "Where are we?" He carefully asked still looking at the girl, who seemed to not matter sharing her figure with him. "And why are we both naked in the first place?"

"This is rest room in our base operating house." She answer back and seeing the obvious shock in the boy continued to speak. I took you here after reincarnating you in order to completely tend yours wound, although there was a better choice for that part, but it seems like I have succeeded. And as why we are naked, it`s because my healing magic works better on the skin directly."

"Reincarnated me?" Tatsumi repeated with uncertain voice, showing his biggest impression on that part.

"That`s right, as devil that is." She explained shortly.

"Did you say a devil? What does that mean?" The brown-haired boy asked another question.

"My name is Rias Gremory and I am a devil as well as your master from now on." The girl answered calmly. "That leads to my question, what is your name?"

"Tatsumi, it`s just Tatsumi." The green-eyed male introduced as simply as he could.

"It`s a nice name. And what about a second name?" Being curious, the girl asked right away.

"I don`t have one, because… well… it`s like that where I came from. Although, I myself don`t know why is that. " The assassin said, scratching the tip of his chin.

"I see. Well, then… It`s nice to have you, Tatsumi." Rias said and smiled at him.

"It`s nice to have…" He began with his reply, but stopped at the second he that he was repeating what his ears caught. "What do you mean by 'have you'?

"Well, you are my servant now, so it`s obviously that you are my property as of this moment." Rias explained and let out a slight giggle.

'Her sake, she says.' The brown-haired boy commented in his mind. 'Well, I will think about it later.' He said and put up on more serious expression on his face as he spoke up. "By the way, thank you for saving me yesterday."

"It`s nothing. I was just passing by when I heard a familiar voice and went to check it. Who knew it would be that insane exorcist." She explained.

"Does that mean you know who he is?" Tatsumi questioned.

"Yes, he shows from time to time and threatens us devils. Last time, he was helping another race, called fallen angels, when we won and if I remember correct, he was to be in prison." She said and stopped for a moment. "But that`s enough for now. I will explain you everything in detail later when the rest of the group gets here. Until then, you stay here while I am out on some private business. I prepared some spare cloths for you in the wardrobe."

"Okay." Was the boy`s short replay.

After that, the girl dressed up and left the room and the house as well. Tatsumi remained behind as told and decided to explore the house in the meantime in order to avoid getting bored. Exploring it, the boy to the conclusion that it was fairly big house, it had a kitchen, both a bathroom and a bath and a huge hall that was well furnished. However, it appeared smaller than the one in which he lived back when he was a member of Night Raid. Still, the atmosphere around was really making him feel at ease and he enjoyed that to the max.

Couple of hours passed and he was still alone, waiting for Rias and the other part of the group to come. That was giving him slightly alarming feeling as he knew that they definitely won`t welcome him with open arms so fast and that was the problem. Past experience though him that getting into the picture of a group of unknown people is really difficult. Back when he joined the assassin`s group, everyone treated him like a extra-luggage and didn`t trust him much, which especially was the case with sniper of the group, Mine. She often mocked him and said he won`t become a part of them. However, he deeply hoped that it will turn like this case in the end, where he can be trusted and respected by others.

Currently being at the hall, Tatsumi sat on a black couch and supporting his head on his hand and continued to think about various stuff, while enjoying the silence that was ruling over the place. Suddenly, the front door opened and three figures appeared from there, one boy and two girls was what he saw on a first sight. However, when they entered the room, he recognized them as two boys and one girl.. The first boy had a brown-spiky hair that resembled his pretty much, light brown eyes and was tall around Tatsumi and probably somewhere around his age as well. His clothing consisted of a blazer over a white, long-sleeved dress shirt with black highlights with a black ribbon on the collar, matching black pants, and brown dress shoes. The second one was a boy with a platinum blonde hair and pink eyes, who the assassin at first mistook for a girl, since the cloths he wore were just like that of the girl next to him. As for the only present female, she had a long blond hair and green eyes, with cloths which consisted of black sweater vest over her dress shirt in place of the cape and corset.

"So you are the one that the President was talking about?" The brown-haired teen questioned.

"Yes." The former assasin replied and stood and walked over to the three and reached his right hand in order to make a handshake. "My name is Tatsumi."

"Nice to meet you, the name is Hyoudou Issei." The other boy returned and took the stretched hand. "Wait, just Tatsumi?! What about a second name?"

"Same goes here. Well, I don`t have a second name." The former Night Raid`s member answered. "You could say it`s my country`s policy not have a one or something like that."

"Really? That`s some strange country then." Issei said in a surprise.

'You don`t have any idea by how much 'that`s some' describes it.' The green-eyed male thought to himself ironically as he remembered the Empire in which he lived.

"I am Asia Argento." The blonde girl introduced herself and bowed down. "And this is Gasper Valdi." She pointed to the other boy that was next to her left, who bowed down as well. "He is…"

"…a boy, right?" Tatsumi guessed, shocking them in the progress.

"You can tell?" Hyoudou questioned with wide opened eyes.

"Honestly, I did mistook him for a girl at first, but after taking a better look I saw his boy-like face. " The brown-haired boy explained.

"You are interesting one." Issei said, cracking up a smirk.

"Excuse me for convincing you. I didn`t do it on purpose." Finally making his debut, the other boy apologized and hid behind Asia.

"Eh, it`s okay." The former assassin reassured him that he doesn`t mind and let out a sigh of relief. "Is that the rest that had to come?" He turned towards Issei.

"No, there are four other members that we are waiting, five if we include the President." The other boy answered.

"By the President, do you mean that crimson-haired woman?" Tatsumi asked.

"Yup! Rias Gremory, she`s the head of our club and our master." Hyoudou explained.

"So you are devils as well?" Tatsumi shot his next question.

"That`s right. Everyone in this club is a devil." Asia answered instead of Issei.

"Well, let`s not just wait standing here and go take a sit, because I am tired from school today." The brown-eyed teen said and made a big yawn, stretching his arms as high as he could.

They followed the boy`s suggestion and took a sit at the sofa and started talking about various stuff, while waiting for the rest of the group to show up and when the time comes for Tatsumi to explain everything before them.
