Shuumatsu No Harem or in English translation, World’s End Harem is that type to story that will only get the attention from males, as the manga represents yet another male fantasy about being the only male around with hundreds of females surrounding the male MC in hopes to get paired with him. This time the setting is based around the “I wouldn’t blah if you were the last man on Earth” saying. Like other male fantasy manga such as Nagasarete Airantou and Infinite Stratos, this manga shares a mutual element with them and that is a dense MC.
Because of an incurable virus, our MC has to go into cryostasis for five years and allow the time for doctors to come up with a cure for those infected, also placed in a five year sleep. When the MC waked up from his cryostasis, he is greeted by is new agent, Suou Mira, who is now responsible for all his needs. After the MC learns he is cured of his virus he soon learns of another problem. Suou tells the MC that the MK (male killer) virus has wiped out the male populace on Earth and left the world in a female-only society. Suou tells the MC that their priority is to get the MC to mate with other women and restore the lost male populace. However, since the MC is a dense idiot he refuses to marry anyone unless it’s his girlfriend from five years ago, who is currently missing. Of course in any man’s situation repopulating would be the wisest choice to do, but this MC can be easily hated when he becomes ignorant of the world’s problem – Humanity is on the brink of extinction with a handful of males left yet the MC refuses to help.
The MC is so despising that as the story goes on new males come out of cryostasis cured of their virus, but end up more likable than the MC himself. As for each chapter, the conclusion to them has a lack of excitement and anticipation that makes the reader wait eagerly for the new chapter to come out. As of now I reckon the only thing that makes readers unable to wait for the new chapter is when they’ll be able to next see the Ecchi content displayed in the chapter.
This manga is at best a 6/10 because its only good traits are providing soft-core hentai and lots of fan-service. This manga does have the potential to become better in every aspect it's lacking, but it fails to deliver. I recommend the only way to like this manga is to see the parts that don’t include the MC, or if you want to stare at the Ecchi content with no interest in the story whatsoever.
