An apocalypse happens in an Earth and there is henge travel from place to place. The blood thirsty protagonists bite several necks through Europe and Asia and then finally get to the USA and then the last battle happens in Canada against giants. Canada's ice wall stops most things from entering Canada, but the Earth ends and Ming and the other four girls of the five horseman or horsegirls leave one Earth through a henge and end up in another Earth far into its future, like several hundred millions of years into its future. Aliens destroy Akiyo's world with nuclear bombs and then Nuclear Winters and Summers happen for a while. Akiyo, because of this, is born in a bunker or fallout shelter. Many prove themselves by going through cave trials that are only open on Akiyo's 5th birthday. Wars happen on the new Earth, people leave the bunkers and the 2001 Gladiator battle happens.
