The "waves" are the world's defense system to "save the world" from an even larger calamity which is the fusion of two worlds. In order to "save the world," the heroes must either allow the sacrifice of 2/3 of the population and ensure the survival of the rest of the 1/3 in the fusion or destroy the opposing world. If the two worlds fuse without the conditions fulfilled, the seal of an even greater calamity will be released, which will be the summoning of a calamity goddess. Which turns out that Bitch spawned from. The other heroes probably chose to sacrifice 2/3 of the population by allowing the turtle to rampage the sealed it for "Heroes'" of the future to use.
