The islanders have sent the women and children away on a boat to protect them from the upcoming battle, but the orcs find and target them. Shindou and Cantil move to stop them, but in the midst of the fight, the earth begins to shake violently as the volcano on the island erupts. Pandemonium breaks loose as volcanic bombs rain down on the island... but this is only the prologue to a much greater disaster. (Source: Crunchyroll)
