Iirc, humans (and all higher races with the exception of fairies) in that universe have been shrunk by elves so that they're basically bacterium by comparison, so that no race will ever pose a threat to elves, and that elves will never even need to think about other races ever again. So in that image it's just like a bunch of cities living in the elf girl's room like bacteria and are getting obliterated, like bacteria.
