The Shadow Revolution was the one of the final battles which occurred in The War of Ragnarok. The attacking group, led by Hikaru, penetrated into Kagegakure 2 and fought with occupying Order of the Apocalypse forces in Kagegakure 2 in order to free the city in the name of Kagegakure 2.
The large Apocalypse Order garrison outnumbered the small group, and the arrival of the Pole Star increased their power. However, the group consisted of the powerful ninjas in the Lost Lands. This meant that the group had a considerable tactical advantage, leading to their victory.
The battle was a decisive defeat for the Order armies, who were also defeated at the Battle at Wulong Forest.
