Be prepared for more pic spam for Level E though. This is an anime that you need to watch in order to understand the jokes.
This is a two part arc so one summary should suffice.
The premise is that an arachnid-type alien strives to diversify their gene pool by mating with several species. The catch is that after their mate dies, the entire civilization of the mate also dies. This is due to the viruses that is contained within the Queen of MacBac (who is the only one that can mate).
Of course, she comes to Earth and instantly locks onto a possible husband. The Dogura aliens, who are the protectors of Earth, need to stop her without enraging her. Luckily for them, the mate turns out to be female! However, that doesn’t deter the
bitch lovely alien.
It’s all done in a fairly comedic way, you really need to watch it yourself.– Jacqivarius
