"Enemy approach the strait. It looks like they're slowing down," a girl reported from the front of the ship. She wore a green armour over her uniform, distinguishing herself as a junior officer.

"At least they learnt so many lessons from us over eight years," a man commented, "Hold your fire until my signal."

He, unlike her, was standing on a command post, signifying his position as the leader. But it's not just where he stood, it's what he wore. He wore an armour far different from other sailors and commanders with many shades of red, signifying he's not just the leader of the ship, but a fleet. The fleet in question were watching in anticipation of the forthcoming battle, hiding behind the mountains. Because it's also night, it makes anyone harder to see them.

The ship in question they're onboard was a galley type ship, specifically a Korean. It was known as Panokseon. It was built for the Korean coast, which were known for unpredictable currents, hence it was built with structural integrity in mind. However, it was not just built for Korean currents, but also the cannons it loads. At the time, while some navies like Japan prefer to board ships and engage in close combat, Korean ships on the other hand was bristling with cannons on all four sides. A ship, especially Japanese, that's designed for boarding in mind would sink itself if it has too many cannons firing at the same time. On a Panokseon itself, it can have at least 20 cannons of various sizes and most out range other ships by a long way.

"I wonder how sis is doing. It's only been a short while since we got her back," the girl walking back to the command post said with worries.

"I wouldn't worry about her. She's a tough nut to crack. Even after Chilchonryang, she still refuse to fight. It's our duty to protect Joseon sea after all," the man said, looking out in the opposite direction of the mountain. From his eyes, he could see a shadow of a dragon like ship only a fair distance away.

The girl nodded in agreement, "You're right. We have to protect our seas whatever the cost."

The man sighed, looking back at the front, "It's been eight years since the invasion began. So many innocent lives were lost. I can still hear their cries even after we liberated them."

"Yeah. Is this why you kept on fight despite our country keeps betraying you?"

The man frowned, making her tense as she realised she said the wrong thing. "The country never betray me. Only that I was in an unfortunate circumstances. I will never betray the king, no matter how much scars he puts on me. I have swore to serve to the people, the king and this country to the very end and that's what I will do for the rest of my life. You still do right?"

The girl nodded, this time with determination, "Yes, Admiral!"

"Admiral, the enemy is moving in," a sailor reported. The Admiral nodded.

"Let a few ships through. If they see their ships move through unscathed, then the rest will follow. That's when we'll strike."

"Yes, Admiral."

Everyone onboard watched in anticipation. Soon enough, a few ships came into the view. The square mast outline that everyone knew were obviously Japanese. Many sailors on their cannons held onto the grip as they watch more ships came into view. Archers watched as they gripped on their bows. Even the girl watched tensely, with her grip on the edge of the ship hardened. The admiral, however, remained still like a rock.

After some time, an entire fleet was already in view. In front of them were approximately 500 ships, five times more than the fleet. This was a massive fleet, but to Koreans, this was just business. 500 ships was nothing to them. Though they have only just above 150 ships of their own, they have the firepower advantage. It's already two hours past midnight and the moon was just covered by clouds.

With the entire enemy fleet in front of his eyes, it's now time to strike. Unsheathing his sword, he let out his battle cries, "Open fire!"

His entire fleet flanking both sides rang out with a massive volley of fire straight at the 500 ships strong fleet in the centre. The sound was deafening as these cannon fire with great power. The cannonballs hit their mark, slamming straight through the light wood of the enemy ships. Many ships outright sunk after taking just one hit. Those that managed to survive found themselves trapped by Korean ships and the terrain itself as they had little to manoeuvre.

"Advance!" the admiral ordered. Every ships from both sides of the strait advanced. A dragon-like ship advanced at full speed, firing its gun at the same time. The enemy ships returned fire with their arquebus. These muskets or matchlocks, while effective against humans, couldn't penetrate the Korean's thick wood.

The dragon like ship advanced full speed at a nearest ship, not intending to stop. Other enemy ships tried to attack from its side, only to be met by more cannon fire. Some tried to jump onto the ship, but it proved to be their fatal mistake as this Korean ship, unlike Panokseon, is covered with a shell with spikes. Those unlucky enough to jump onto it got themselves impaled, killing them instantly, bleeding to death or fall back into the waters to their death.

Inside the dragon like ship was another girl looking out the porthole. "We almost to the enemy! Hold still! It's gonna be rough!" she shouted, holding onto something. Many sailors inside the dragon ship braced themselves for the collision to come.

On the flagship, the girl watched as the dragon ship heading at the enemy ship at full speed. A few seconds later, the ship made contact with the enemy ship and rammed it out of the way.

"Archers!" the girl shouted, raising her bow with her arrow on fire. Other archers followed suit, also with their arrows on fire. Their target was the enemy ship that was rammed away. "Fire!"

The archers let loose a volley of arrows at the enemy. The arrows flew across the waters before into their intended targets. Many enemy sailors onboard this ship were hit by the arrows. Some were killed instantly, some recoiled into the waters, some even set on fire.

From his command post, the Admiral watched the battle going in his favour.

While half of the ships in the fleet were Korean, the other half belonged to Ming Chinese. These consist of a few War Junks, two Korean warships gifted to them and many lighter ships of various sizes. They were already in the same battle as the Korean, but to the Chinese admiral onboard a Junk, he was getting a bit agitated for a 'real' battle.

"This is going too slow. Is this a naval battle?"

"That what the Korean say so," a subordinate said.

The Chinese admiral scoffed, "Arrows and cannon fire, yes, but they're merely used to soften up the enemy. Perhaps it's time for boarding."

"Admiral! Didn't that Korean said to avoid boarding! They said our enemy is superior when it comes to melee combat! Besides, there's still some enemy ships still in good condition!"

"Are you saying the Chinese are weak against the Japanese in melee? There's no way a pack of thugs and pirates are better at sword fighting than us Chinese! We represent the pride of the Chinese at sea! Now, tell all our ships to prepare for boarding at once!"

The subordinate nodded and gave out his superior's orders, "All ships, prepare for boarding!"

The Chinese ships advance towards the enemy fleet, firing its guns and arrows at the same time. Once they got close enough, some sailors from both sides jumped over each other ships, swords and spears in their hands. Onboard these ships, the Chinese and Japanese fought each other in hand to hand combat. But soon, the number of enemy ships grew and surrounded the Chinese.

"Admiral, the Chinese is getting too close to the enemy! They'll get surrounded by the sheer number!" the girl shouted. She watched as the Chinese junks and other ships got close enough that many sailors board each other ships. The enemy responded by sending more ships towards the Chinese like a pack of shark after its prey.

As she watched the battle not going their way, her vision flashed as these junks were replaced by warships similar to hers. Trying to get that vision off her head, she had her hand on her forehead and shook it off.

"-can you hear me?" a male voice getting into her head.

"Huh? Sorry?"

"I gave out an order. We must save the Chinese."

"But admiral, this will be a close combat fight, something you don't want to face!"

The admiral face was indifferent, "I know, you know, everyone knows. This battle will be close combat, whether we like it or not. It's just a matter of being prepared for it. Are you?"

The girl looked back at the battle before looking at the admiral with determination, "I'm ready."

The admiral nodded and turned to his captain, "Captain Song, full speed ahead towards the enemy. We must save them or the enemy will break through."

"Yes admiral. All ships, full speed ahead!"

From below decks, rowers rowed harder to achieve the speed, with the drum beating to keep the cohesion going. The girl can hear the drums beating from below as the ships advanced at a great speed into the midst of the battle. Many sailors gripped on their spears and swords as they get closer to the enemy.

Cannons rang out of the ships to try damage the enemy as they close in while archers rain fire to keep the enemy sailors' heads down. The enemy kept a barrage of arquebus fire to keep the Koreans' heads down as well. One unlucky Korean sailor was shot in the shoulder, screaming in agony. His fellow sailors pulled him out of the line of combat as they tried to bandage the wound.

"Keep advancing, we almost to the-" An arquebus ball slammed into the Captain's head, knocking him to the floor.

"Captain Song!" the girl shouted in shock as she ran up to the Captain. Fortunately, she found that his helmet protected him, but it put him in momentary unconsciousness.

Because the ships gotten so close, sailors on her ship threw stacks of woods on the enemies, with archers firing their fire arrows at the wood to set them on fire. The battle became desperate as both sides fought each other in close hand to hand combat, using whatever weapons they had on hand.

The girl shoot off enemies trying to jump onto her ship, but inevitably some made it threw. As she shoot off more arrows, she was unaware an enemy soldier coming up to her from behind with his katana in his hand. Just he was about to strike, an arrow embedded itself straight in the neck, forcing the girl to look behind her and then looked where the arrow came from: The admiral, holding his bow.

"I don't want you die on this battle. Your life is indispensable," he said to her, withdrew his bow and unsheathed his sword. The girl nodded, notching another arrow onto her bow.

As she drew her bow, she saw another ship sailing by her ship. This ship, compared to the other ships in the enemy fleet, was larger than other ships, with gold decorations at the bridge. On the bridge was a man with an impressive armour compared to a standard armour on regular enemies, signifying of great importance, which she knew immediately over eight years: An enemy commander. She took a quick second in aiming at him before letting loose the arrow. The arrow made its mark and hit square on in his chest, instantly making him fall.

Everything stopped momentarily as the enemy tried to find where the arrow came from and laid its eyes not on the girl, but the admiral.

"Yi! It's Admiral Yi!" one enemy sailor shouted in Japanese, pointing at the Admiral. The words rang out across the entire battlefield. Soon the enemy fleet redirected their ships from the Chinese straight to the Koreans.

"Good shot. We saved our allies. Now it's time to lure them out," the Admiral, Yi, congratulated her. "All ships, lure our enemies away from our allies!"

The Korean ships turned around and sail in opposite direction, with the enemy fleet in hot pursuit. In doing so, however, broke the encirclement around the Chinese ships.

Onboard the flagship, the Chinese Admiral watched as his Korean counterpart saved his fleet and put off the stress on his fleet.

"Even if the odds are stacked against you severely, you never gave up the fight. If only I could be like you..."

The sun began to rise as the scene of battle began to lighten up. There were many smashed woods, dead sailors from both sides and sunken ships littering the waters. However, it was mainly the enemy and the results were clear: the enemy were severely damaged and losing.

Seeing no point in continuing, many enemy ships began to turn and retreat towards the sea. Everyone cheered as they saw the enemy running away. Admiral Yi, however, wasn't satisfied.

"Admiral, the enemy is retreating!" Captain Song, who woke up only moments ago, reported with excitement. Yi only looked at him with indifference.

"The battle is still not over. Our objective isn't just to stop the enemy, it's to destroy their entire fleet so they will never become a threat to Joseon again."

The girl looked at him in shock, "Admiral?"

"We already seen enough destruction they made on our lands. Now it's time to teach them a lesson," Admiral Yi explained. He already seen hell the enemy made on land, with many dead innocent lives bleeding across the fields of Korea. To him, he wanted nothing less than a complete destruction of the enemy fleet. "Sound our drums! Pursue them!"

With these orders, the fleet began chasing after the retreating enemies. Cannons fire tear through the wood of the enemy ships, with arrows pouring out to keep the enemy from firing back. As the fleet charge at full speed, a new sound began to fill the battlefield. It was the sound of drum beating. The beating of the drum drove the fleet ever faster and it was so immense that it was as if the god of war was upon the enemy.

When the girl looked back, the source of the drum beating was not an ordinary sailor, but Admiral Yi himself. He kept his eyes forward while beating the drum, urging his sailors forward.

Concentrating her own battle, the girl kept on letting loose arrows. As the ships kept on advancing, an enemy ship began to pull aside the flagship. Unknown to anyone, another girl was onboard this enemy ship. This girl, however, looked like the girl onboard the flagship, except she had an unnatural white skin and hair with red eyes and for odd reasons, she gave off a creepy smile. On her two hands was an arquebus. Her eyes laid on her counterpart. Her smile grew larger, becoming a smirk. She took aim and set the fuse on her arquebus.

As this girl on her flagship let loose another arrow, everything went quiet and time slowed down. Everything except a distinctive sizzling of an arquebus about to fire. She slowly turned to see the other girl with her arquebus aimed straight at her. The fuse on the match was only moments away from firing and there's not enough time to dodge. Her two eyes locked at her fate.

SSSSSS-

BANG!

She was knocked down onto the deck hard. All her breath forcefully went out of her body. It was almost as if she died. Except she could still move and feel. She looked around her body and there wasn't any wound. However, there's a shadow above her. When she looked up, her eyes widened in shock and terror.

In front of her eyes was her admiral, with a deep wound straight at his left armpit. It's no light wound, or even a wound that maybe survivable. It's a fatal wound with no chance. Slowly he took one look at his wound and collapsed.

"Admiral!"

A/N: Yeah I'm not good at heavy drama like this. It's been a while since I've been writing. My last chapter I've written on any stories was over 8 or 9 months ago, so naturally my writings a bit rusty. Also it's been a while since I wrote a Kancolle fanfic.

Anyway, this fanfic is based on Imjin War during the late 16th century. Politics and flame wars aside, this war was devastating for all three sides. To cut a long story short, there was another battle in Japan that finally put an end to Sengoku Jidai period and the end of Toyotomi clan. China, which was known as Ming at the time, fell to the Manchus, establishing Qing dynasty. Korea, known as Joseon, stayed for another three hundred years but its land was devastated and its former glory never came back until it was conquered by Japan, this time without Admiral Yi stopping them.

If this battle wasn't obvious to you, it's Battle of Noryang, the last battle of Imjin War, between allied fleet of China and Korea against the Japanese. This was also Yi Soon Shin's last battle, and as the story goes from above, he died in that battle. I bend history a bit to fit this girl, since she is quite important. This prologue might not look like Kancolle since it's onboard a ship rather than ship itself, but we'll get there. We just establishing context.

With Admiral Yi, calling his action 'remarkable' would be an insult. It's not just remarkable, it's as if he's a god. Out of all his 23 battles, he never lost once, and most battles he was outnumbered. He had many advantages on his sides, but we'll discuss them as we go along. But even then, he won all of them despite being heavily outnumbered and the government fucking with him.

A tid bid trivia is that Togo himself said that 'You may compare me to Horatio Nelson, but not to Yi Soon Shin, as he has no equal.'

For those disappointed it doesn't look like Kancolle, it will be on next chapter.

Update: I feel that the last part isn't suited at this point so I decided to remove it.
