Many years ago: 2001.

Far from Japan coast is a small island populate of villagers that been isolated from the rest of the world.

Long time ago these villagers came from a land called Oros but they left due to population.

Since then things been quiet and peaceful for these villagers.

But after years of isolation the villagers never thought they would meet outsiders.

These outsiders are Japan heroes: Union.

These heroes want the island only to be rejected thus the heroes fought but found themselves powerless as soon as they attempt to use their powers.

Thus forcing Union to leave the island but not before they place a nuke which would detonate in a few minutes.

Thus the chief put his only one year old son, Y/N onto the only boat the villagers could built in such a limited time.

While Y/N was far away the villagers surrounded the nuke and accept their death as it went off.

In the distance Y/N saw the cloud but as it glow so did Y/N who unexpectedly unlock his inner beast spirit.

Present: 2023.

In Central Europe there is a building where a grown Y/N is having a meeting with his inner circle.

Y/N: "Greetings gentlemen. Today is the day we strike Union" he said.

Pagan Min: "Kyrat is prepared for war" he said.

Joseph Seed: "Montana is prepared for the collapse" he said.

Antón Castillo: "Yara is prepared for anything" he said.

These three men are responsible for many things:

Pagan Min as head of media, propaganda and news.

Joseph as head of religious affairs.

Antonio as the head for industrial and military affairs.

Sure they rule different places but united these men are a threat to everyone that dare to oppose them.

Now they share a common enemy: Union.

Union try ruining everything these men have built and created but failed since they weren't Japan responsible.

An: Most of these places are in United States, Europe, India, or Caribbean sea.

Y/N: "Then let show Union why the United International Society will be their doom" he said smiling sinisterly.
