High School Fleet: Hunt For The Red October

Prologue

In 1905, in the alternate world of Haifuri, the Russian Empire succeeded in defeating the Japanese Empire in the Manchuria area, but their movement was stopped at the border of the Korean Peninsula, because the bitter defeat, the Japanese Empire was mining for methane Hydrate, but when WW1 erupted in Europe, Japan became an ally and took the islands that were under the influence of the German Empire.

During the Bolshevik Revolution in the Russian Empire, the troops near the borders of Manchuria and the Korean Peninsula were weakened and then used by the Japanese Empire to take over Manchuria, because of this, Manchuria became a Japanese puppet state called Manchuko. During the Second World War, Japan entered the role of WW2, but during the Battle of Midway, there was no loss from the Japanese side, and the loss went to the US side who lost Yorktown.

Then at that time the Musashi survived the US attack and at that time also entered Operation Ten-Go, a suicide operation, but the two ships were redeployed after their naval forces were no longer able to accommodate the US combat power until finally Japan lost and its European allies, the sunken IJN Shinano was rebuilt in 1946, and later became the battleship as the Yamato and Musashi in 1950. Japan had its imperial government, but changed the doctrine of government.

In 1950, Yamato, Musashi, and Shinano along with western allied ships took part in the Korean War, but Japan becomes the first country to buy jets from the US, such like F-86 Sabre, and when the cold war occurred, Japan ordered an aircraft in the form of the F-4 Phantom, and at the end of the Cold War, the Japanese built the F-1, their own aircraft.

In 1970, an organization called the Red Fleet was created to build all ships in all oceans including the Pacific, Arctic and Black Seas

Japan continues to mine methane hydrate again, but it resulted in the future right in 2010, Little by little the Japanese mainland began to sink, this was known by the United Nations so that the United Nations immediately formed an organization in Japan called the Blue Mermaids.

After this happened, marine vehicles were added and several floating cities were built and also received support from the outside world, JASDF was temporarily disbanded, the reason the JASDF was temporarily disbanded was because all the military airfield including planes and helicopters were all sunk in 2010, and that's why Japan built an aircraft carrier to house the new jets

Before all that, in 2004, 5 Russian Navy ships stolen by the Chechen rebels were destroyed by just one ship in Japanese waters and the captain of that ship was none other than Mayuki Munetani, the "Tomoe Gozen of Kurushima", Mayuki was given an award by the Japanese Prime Minister himself for her bravery.

In 2019, there was an incident, The incident was called the Totalitarian Disease Incident, but was successfully eradicated, but 5 weeks later an unknown pirate group hijacked a Floating Fort named White Dolphin, however the pirates were captured and the White Dolphin was destroyed. But the problem did not end there, it was reported from Russia that there was a Second Russian Civil War so that Russia fell into an ultranationalist party that was loyal to the communist party in the past.

Because of this the world is threatened because Russia has become a country controlled by ultranationalist parties that can harm European and Asian countries including Japan, all countries became wary of a war move from Russia that would make the world fear. Not to mention Russia has diplomatic relations with the PRC and North Korea which has made the world even more in fear. In 2020, Russia annexed Georgia and Ukraine included Ukraine and Georgia as part of its country and even Belarus entered into Russian territory without resistance.

Because of this the former Soviet Union countries such as Kazakhstan, Kyrgyzstan, Moldova, Uzbekistan, Turkmenistan, Armenia, Azerbaijan and Tajikistan were forced to join Russia. Russia finally became the Union of Russian Republics which made the west even more wary, not to mention that, Finland, Estonia, Latvia, Lithuania left the EU and was forced to join Russia.

In year 2021, China, North Korea, Cuba and Vietnam has now joined the League of Red Fleet Organization, new name for Red Fleet, the group's formation is clear warning that further intervention in the Pacific Ocean by the Blue Mermaids and it's allies will not be tolerated

Needing to mobilize their navy in the Pacific, in year 2022, Russia is targeting Japan which the Japanese side doesn't know about yet so war will arise.
