Everyone thinks that Yi Sun-sin is dead after the Imjin War.

However, it's unimaginable that Yi Sun-sin, the hero of war, the hero of legendary victories like the Battle of Hansando and the Battle of Myeongnyang, would be killed by fleeing Japanese forces.

Yes, Yi Sun-sin is alive.

Joseon faked Yi Sun-sin's death and was plotting to conquer Japan to avenge the Imjin War.

The problem was funding. Since it was so soon after the war, building a large fleet was impossible, so they decided to use special agents to conduct the battle.

They summoned Western war heroes and infiltrated Japan. Thus began Yi Sun-sin's conquest of Japan.

Koren and his friends, medieval Western heroes,

had recently acquired Excalibur and the Divine Arrow, Varus.

They were bored by the fact that they no longer possessed any more powerful weapons.

One day, Koren heard some interesting news. The Eastern general Yi Sun-sin possessed the most powerful weapon in history. The story goes that no one can defeat Yi Sun-sin.

Koren and his friends arrive in 16th-century Joseon through a portal between time and dimension.

Koren seeks the ultimate weapon.
Yi Sun-sin plans to conquer Japan.
Japan seeks to invade Joseon once again.

And their guardian deity.

Now, a new war begins with Yi Sun-sin's Hero Battle.
