If you do not want to read a Fanfic where a character is horribly beyond overpowered then do not read this Fanfiction.

In this AU Tatsumi is older than Ieyasu and Sayo, and when Tatsumi is 19 he is only 3 years younger than Esdeath.

Disclaimer: I do not own Akame ga Kill, if I did I would make Tatsumi look like an effeminate boy.

Chapter 1 The Black Shogun

Tatsumi, a little 8yr old boy, was just exploring the hills to the north of the village. When he suddenly fell into a hole screaming, after what felt like hours he landed on top of a… weird soft blackness?

"Uurrnngghh… my legs hurt a little… Where am I?" Tatsumi was confused at where he is.

The only thing in the black room was a simple black and purple crystal that has a eerie red glow around it.

But the child was only curious at what it was…

"What is this? It looks weird..." Tatsumi grumbled.

Tatsumi ran up to it throwing his non-existent caution to the wind, and without really thinking much grabbed the crystal with both hands.

"This thing looks cool actuaaaAAAAAHHHH!" PAIN exploded throughout his small body, he screamed so loud but nobody could here him as the hole above him sealed up to test the small child to see if he is worthy.

He doesn't know how long he was in pain and screaming but it felt like days, when in reality it was only a few hours. His small body started having noticeable changes, such as dark purple highlights streaking a bit in his hair, and if his eyes were open they now glow red, and his physique will grow into that of an effeminate boy in the future, but he doesn't know that… yet.

The pain finally stopped and Tatsumi got knocked out.

In the mind of one Tatsumi

Tatsumi woke up on a bed fit for a king, he is confused as to where he is and why is he here, because the last thing he remembered was that he was in horrible, horrible pain.

"So you finally awaken."

Tatsumi looked to his right, and saw a black armored man.

"Who are you?" Tatsumi was confused at who he is.

"I am the living embodiment of the "cool crystal" you grabbed, my name is Kage."

"Hi! My name is Tatsumi! Nice to meet you Kage-kun! Sooo…. Where are we?" Tatsumi asks.

"Weird kid, he isn't scared of me at all." "This is the inside of your mind and I am here because I am to help you control your new Teigu abilities of the Kurai Kotei." Kage informed.

Tatsumi looked at him. "The Kunai Kutee? What's that, and what are taiga?"

Sweatdropping Kage corrected him. "No no no, it's Kurai Kotei, and it is a Teigu. The crystal that you held and absorbed into your body albeit unintentionally is a Teigu called the Kurai Kotei."

"What is a Teigu?" Tatsumi asked.

"Teigu or Imperial Arms, are weapons made from various parts of different kinds of powerful danger beasts or made out of an entire danger beast itself. These weapons if they accept a user, it gives them control of their Teigu's special abilities, as well as making them slightly faster and stronger, unless it's a Teigu that boosts the strength of your body, your body will only have a minor boost."

As Kage finished explaining what the Teigu in general are. Tatsumi was sitting upright and is listening intently.

Tatsumi can't help but ask. "Soo… what does the Kurai Kotei do?"

Kage smiled. "The Kurai Kotei is a powerful Teigu that if you can control well, you can create a very, very large army as well as use the powers of shadow and darkness to defeat or kill your enemies, and when I say create a very large army that means everything an army can have weapons, armor, how proficient are they at fighting as well as if you want to be creative with your army, you can create beasts as well as cannons, the only cliché limit is your imagination."

Tatsumi was in shock. "And you are gonna train me to do this?"

"Yes. I am." Kage just smiled.

Tatsumi is excited and is jumping on the bed. "Yes! I can use this to protect my precious people! Oh wait I have to go back to the village, how do I get out of here?"

Kage chuckled. "It's simple this is your mind you can create an exit for yourself if you want."

Just as he finished that sentence, a black and purple portal swirled into existence at the end of the room.

Tatsumi then slowly went up to it. "Well that was easy. Bye bye Kage-kun!"

"See you later Tatsumi-chan~." Kage smiled.

Tatsumi woke up to see that he is now on the ground in a clearing just north of the village. "Huh, weird I thought I was underground." What he didn't know was that the blackness lifted him back onto the surface during the time Tatsumi was in his own mind.

"Welp, gotta head back to the village!" Tatsumi all but shouted.

5 minutes later

Tatsumi arrived at the north gate and he saw Sayo and Ieyasu. "Hey guys! I'm back!"

Ieyasu and Sayo immediately jumped and knocked their older brother figure of his feet.

"Ne ne~ Onii-chan! Why do you look so different now, where did you go, what did you find?" Sayo questioned.

"Yeah yeah, big bro! What she said!" Ieyasu agreed.

Tatsumi just laughed at the two, his two "siblings" were always excited at him and his little adventures whenever he leaves the village.

Sayo the 5yr old little sister that he will always be a sucker for, as her puppy eyes are very powerful. Tatsumi is helping her with her sensei on how to use the bow effectively. She is a little girl reaching only to his chest with straight black hair and black eyes with a round cute baby face. She will get prettier as she grows older so he is already thinking of creating some hidden guards for her.

Ieyasu is also a 5yr old but he is a little shorter than Sayo only coming up to her ears and Sayo never lets him live it down its hilarious. He has black messy hair held up by a white bandanna and brown eyes with a less round face than Sayo. Tatsumi is helping him in how to wield a broadsword as Tatsumi is strangely very proficient with swords in general.

"Slow down you two, and wait a bit, because this time I found something strange, and it is also why I look like this now. I fell into a hole a long way to the north of here, and I found a weird looking crystal."

Sayo and Ieyasu were now on the floor listening, as Tatsumi was telling his story, the village elder was also listening in as well as a few of the others, because Tatsumi did not tell stories like these unless they were true. As some of the detailed stories Tatsumi told, were actually helpful to the village.

"This crystal was glowing with this weird dark red aura, and when I grabbed it, I felt pain all over my body. It felt like hours before it finished. But when I woke up, I was in my mind, and there was this guy who told me I was accepted to be the wielder of this thing called a Teigu." Tatsumi revealed.

The village elder immediately looked alarmed at what he just said.

"After talking to the this guy, whose name is Kage, he told me I that with this Teigu, I can manipulate and use the powers of darkness and shadows, to help me, and defeat my enemies, and that he would train me in how to use these powers." Tatsumi finished, and he demonstrated by holding up his right hand, and created a purple orb with black flames and lightning and a red glow.

Sayo and Ieyasu were amazed at what he can do now. However, the village elder was not.

"Tatsumi… I am sorry but you must leave this village." The elder grimly stated.

The three children looked at the elder in shock. The elder gently explained.

"I am sorry, but if the Empire catch wind of this village having a Teigu user, they will destroy this village looking for you. I am sorry Tatsumi, but for the safety of the village, you must leave and never return." The elder stated.

Tatsumi heard stories of the darker side of the empire. He knew that the elder was right, and that his power will only attract the wrong attention.

"Old man! You can't do this! Our brother can take them on with his new powers!" Ieyasu shouted.

"Yeah! We will help him and we will become the guardians of this village!" Sayo yelled.

Tatsumi did not want them to die because of him, so he made his choice.

"Its ok… both of you stop it." Tatsumi gently said.

Everyone looked at Tatsumi.

Sighing Tatsumi asked. "Can I at least pack a few things, and say my goodbyes?"

Saddened, the elder could only nod, as he watched the boy he raised like a grandson, walked away.

10 minutes later

Everyone is at the eastern main gate, ready to see Tatsumi off. The 8yr old boy, packed everything he needed, and looked back at them to say his final goodbyes. Tatsumi moved toward Ieyasu first.

"Big bro, you can't leave us… We can take them. We can protect this village!" Ieyasu argued.

Tatsumi smiled. "I'm sorry, Ieyasu but I can't stay here, but. You must stay here with Sayo and keep this village safe from the danger beasts ok? Stay strong for me and the village ok?"

Crying Ieyasu can only nod and say yes. Tatsumi then moved toward Sayo.

"Onii-chan… Please… don't go…" Sayo cried out.

Tatsumi hugged the girl closer. "Sayo I want you to stay true to yourself, help Ieyasu and this village for me. Also, please look out for Ieyasu, you know how reckless he can be."

Ieyasu yelled in the background. "Hey!" Sayo giggled at that because she knows its true.

Tatsumi then moved out towards the gate. But he got one last thing to say to the two. He turned around and yelled out.

"Hey! Sayo, Ieyasu! If you are stubborn enough to leave the village when your older to look for me! Don't trust any people that try to help you out of their own way! Even if they look innocent! Just telling you two! Because if you are as stubborn as I am, you will leave when your older!"

Tatsumi then turned around and started walking towards the forest. Never to be seen for years.

11 years later

We see the a figure on a cliff watching the Northerners getting overwhelmed by General Easdeath's army and Three Beasts. They were slaughtering the rebels leaving very few survivors, and the injured got captured as their prisoners for later.

The figure was 5'6 tall with a very feminine looking body and face, long legs and a round butt with soft hands, wide hips, basically a body that can give General Esdeath a run for her money. The figure's face is soft and having long black curly hair with a few dark purple highlights, their eyes are a rounded shape to look innocent yet the glow of dark red eyes say otherwise, in a strange black armor with purple lining and a dark red cape (Black version of Sengoku Basara Nobunaga Oda armor without the helmet) befitting of a leader that can fight and command at the same time.

"So Tatsu-chan, are you going to intervene in this battle?" Kage, the resident in his mind asked.

The now revealed Tatsumi now just said. "I do believe that now is the time. I will have to summon the Shadow Samurai now."

Just as he said that. Just outside the wall, the land suddenly got enveloped in darkness, and due to the stronghold being uphill, the General's army noticed it.

Sounds of "What is that?!" "What the hell" "What in the fuck is going on out there?!" However, the General and Three Beasts were confused the most.

"Esdeath-sama, what is that?" Nyau, a blonde boy who looks like a tomboy girl questioned.

"I have no idea Nyau, but I can see something moving in it." General Esdeath answered him.

Just as she said that the darkness lessened, only to reveal their new enemies.

Soldiers with strange black armor and helmet and dark purple clothing underneath (Shogun 2 Soldiers), walking towards the stronghold getting in formation. They wield katanas of pure silver with a black handle and a purple hand guard. There are different soldier types it seems. There are soldiers wielding the katana only (Katana Samurai), another group of soldiers wielding these naginatas with the same type of armor (Naginata Samurai), weird soldiers that have this cone like hat with less armor and wielding a spear, another group with the same look but longer spears (Oda yari and long yari Ashigaru), and there are also two types of archers with the same two different armor styles at the back (Samurai and Ashigaru Archers) they all wield the same katana for closer melee combat it seems.

From what Esdeath can see, the forces outside the stronghold outnumber hers by a long shot, while she commands an army of 500,000 soldiers, these new enemies outnumber that by 5 times the amount, where did these northerners get this kind of army she doesn't know but she will find out.

Grabbing the man, Numa if she recalled correctly, she demanded. "Who are they, are they your allies? Answer me weakling."

Numa only answered in fear and, awe? "I thought it was just a rumor… an army of onyx, summoned by the one who controls the forces of shadows and darkness… The Black Shogun…"

Esdeath was confused. The Black Shogun? Who was that? She just knows, for some reason that this Black Shogun, will give her a very fun challenge. Just as she thought that, darkness swirled into existence a few feet away from her, Numa and the Three Beasts.

Out of the darkness Tatsumi walked with a swagger, wielding a gun (Reaper's Gun) and a Long Broadsword (Nobunaga's Sword) in his right. Walking slowly toward Esdeath, she saw four different warriors with various black armor behind him.

"Are you the beautiful Esdeath?" Tatsumi asked with an innocent smile but with a mischievous gleam in his eyes.

Esdeath can't help but blush at the smile, shocking everyone else that General Esdeath blushed because of the wrong reason. "So I believe it is correct to assume that you are The Black Shogun?"

Tatsumi smiled and giggled (yes giggled) at her question. "Yes, it is an honor to meet an artist in battle such as you Cold Commander." Laughing outright at the confused look on the others' faces.

"Cold Commander?" Esdeath questioned at the nickname she did not know of. "Yes, the Cold Commander, the strongest general alongside the Golden General, you are infamous for your ruthlessness and use of the coldest of ice to annihilate your enemies." Tatsumi explained.

River, an old man, but is still strong regardless suddenly questioned. "What is your purpose here?"

Tatsumi just smiled. "I am not here to help the northerners, oh no I am not. I am just here because I want to see the strongest general of my little brother, also I have various forces around the country making sure that Empire forces do not loot, pillage, and rape, and your little band of soldiers are no exception. As for why? Well I want to see my little brother's reign last long, and I can't have that if the Empire's Soldiers loot, rape and etc. to their own people, creating unrest for more rebellions, and thus making more people support the Revolutionary Army."

Esdeath smirked, and readied her rapier. "Well then regardless of whether I win or lose, which is highly unlikely, I will tell my forces to stop looting, pillaging, and raping, these rebels and the future rebel towns. However the rebel fighters will die."

Tatsumi matched her smirk with his own, and aimed his gun at her. "That is acceptable, well shall we?"

"Let's" Esdeath agreed.

The ground beneath both their feet exploded, as they ran at each other at inhumane speeds. Esdeath thrusted her rapier at Tatsumi's chest, however he parried her blow with his sword and aimed his gun and fired a shotgun type shadow blast at her. She ducked and span around him creating an ice platform to jump off of, landing in front of him, she started thrusting at rapid fire speeds, Tatsumi matched those thrusts, parrying them with his sword, and started firing and slashing at her in a very strange but effective style of fighting (Faster version of Sengoku Basara Nobunaga Oda fighting style).

She jumped back creating in the sky a large amount of ice javelins, and launched all of it at him, while Tatsumi jumped up and his gun disappeared and creating another sword and started deflecting and parrying all the javelins back at her while infusing it with shadows to prevent her from controlling it again.

Esdeath dodged all of the javelins, and started charging her trump card, seeing her charge up her trump card he did the same, and started charging his trump card. Ice and snow gathered and crystalized around Esdeath, while darkness and shadows started swirling and solidifying around Tatsumi.

And they let loose themselves.

"Mahapadma!/Andhere Anant!"

Ice and shadows merged together and exploded outward in a violent manner creating a crater where the citadel once stood, luckily the others retreated back because they knew that the battle would be big, but by the Emperor that was an understatement. When they looked at the bottom of the crater they saw two figures one with frost coming of their body and the other shadows coming off the other one.

"Hahaha… Looks like our trump cards cancelled each other out, my Trump Card was supposed to freeze time itself in a 20 km radius." Esdeath revealed.

"It, appears so… my Trump Card was supposed to engulf everything in darkness crushing everything and breaking your very soul in a 20 km radius as well." Tatsumi revealed as well.

Tatsumi had frost coming off his body and Esdeath had shadows coming off hers.

Esdeath felt herself losing consciousness. "What? How could I lose?"

Tatsumi walked up to her. "I have probably practiced with my Teigu longer than you have, besides you are interesting, and if you want, I would like you to be my girlfriend." Tatsumi smiled.

Esdeath blushed at the smile. "I was about to say you have responsibility for what you did to me, but you just prevented me from doing it. I would love to be your girlfriend, I can show you. so. much." Esdeath eagerly stated.

"I look forward to it, I just hope you can keep my siblings safe from the Capital." Tatsumi smiled.

"Welp, I am going to pass out now, I want to talk to you when I wake up. Honey~" Esdeath finally lost consciousness.

Tatsumi carried her in a piggyback style and started bringing her back to the camp of hers. The others pissed their pants and started fearing for their lives including the Three Beasts, but Tatsumi just informed them that.

"Es-chan, will inform you about everything when she wakes up, you only need to know that as long as you and the other forces do not loot, pillage, rape, and etc. then I will let you just start setting up camp and interrogating the rebels, and if I hear a word of rape, or even if I smell it… you know what will happen. Now will you excuse me." Tatsumi threatened them, and started moving to a clearing where the camp will be and created a small house from the shadows.

Inside he placed her onto the master bed all the while sitting with her head on his lap playing with her hair, and started to doze off.

"I wonder what will happen next..."

Now this chapter is done and over, stay tuned for the next chapter because I have to think for a few flashbacks. Anyway you have probably seen the (Notice).

The soldiers of onyx are Shogun 2 Total War Soldiers some of them are from Shogun 2 as well as the Artillery. The various units from the game that will be listed here as I will not repeat myself:

Katana Samurai, Naginata Samurai, Yari Ashigaru, Long Yari Ashigaru, Bow Samurai, Bow Ashigaru, Yari Cavalry, Armstrong Guns, and Gatling Guns.

These units are of a custom version of some real or anime ships and will be seen later on:

Gigant Battleship- are Man o war type of ships with three to four levels of cannons, black body with dark purple lining and lights are dark red the sail is also dark purple with the top flag being a dark purple flag with a black symbol of a dragon skull with glowing red dots for eyes. Also these ships can fly. They use similar wings of Dragon Nest flying ships.

Anant Destroyer- is a smaller than Gigant Battleship with only having two levels of cannons, it has the same color scheme and mechanics of the Gigant Ships.

Endless Nautilus- these ships are classified as a ship used probably for trade and transport but they have firepower on board as well just in case they have two levels but only using the first level for cannons as the bottom is used to store goods and supplies.

Andhere Anant is Hindi for Darkness Infinite or Infinite Darkness I forgot.

Anyway review what you think but do not insult or flame for it will only be erased so that is all and I hope to see you guys later. This is The Oblivion Overlord signing out.
