tl;dr: A short manga with a few really good jokes and skits but that is otherwise lacking. This manga is pretty short, only one volume long, and essentially tells the story of the last human in the universe after Earth is destroyed. He gets picked up by a couple other aliens out of Earth’s wreckage but seems to have lost his memories. Still, the fact that he’s the last member of his species really gets to him, and thus he decides to go on a journey to try to make offsprings. The chance of different species successfully mating is incredibly small though, so he travels allaround the universe in order to mate with as many women of as many species as possible.

As it goes on it deals with other plot matters, such as him getting his memories back and discovering why Earth was destroyed in the first place. However, overall, the plot isn’t that important, nor is it that good, basically just being an excuse to get involved with various alien and space related things. The characters similarly aren’t that great, with none of them feeling all that worth getting invested in.

The only aspect of this manga that felt like it had any substance was the comedy. This comedy can be pretty great at times making good use of the opportunities that sci-fi comedy allow for smart and unique jokes that feel somewhat reminiscent of the Hitchhiker’s Guide to the Galaxy, which makes sense considering the plot is somewhat similar as well. Unfortunately, the comedy falls flat as much as it lands well, and thus while there were certainly moments that were funny, overall the comedy was only okay. The art works well with the comedy at times, but overall I thought it looked pretty awful.
