Within 24 hours of examining a patient presenting influenza symptoms the patient dies from multipleorgan failure followed by several others who have shown the same symptoms. Soon after the mysterious virus quickly spreads across the country and as the death toll rises even the highly trained medical experts in Japan with all the most advanced medical technology available to them are at a loss over how what this virus is and how it spreads. Soon the whole country goes into lock down trying to contain the virus as it continues to spread all over the world doing whatever they can to further prevent its spread within their own country. Unfortunately as I was reading through this manga it felt like the highlight reel or an edited down version of a much longer story as it goes from scene to scene without much of a proper transition making the pacing of the whole thing feel very rushed as it quickly takes the reader from situation to situation without stopping to give them some breathing room. Im assuming that the manga was trying to go for a breakneck speed to make you feel as tired as the scientists politicians as well as the population at large in the manga as they have to go through trying to find a cure for the virus as well as try to prevent it from spreading and have to watch the world around them suffer from something so awful but it just feels like it still needed a few scenes to allow the manga to breath and give the reader a much needed break every so often as well as give a few of the characters a scene or two for the reader to get to know them better even briefly which could easily help reinforce just how much the characters have to hurry to prevent the spread of the virus. At only one volume in length the story might have been just too limited by its short length and probably should have been given another volume or at least another few chapters for it to not feel so rushed. But the highlight of the manga is the art done by Masasumi Kakizaki who was also the author of the manga as it really shines through as it gives the manga some much needed weight to the situation that its presenting. Masasumi Kakizakis art is very visceral and detailed and it really added some impact to seeing the effects of a large scale virus killing millions of people as uncomfortable as it might be. Kansen Rettou isnt my favorite out of Masasumi Kakizakis work that I have read of his and thats probably because it tried to bite off a bit more than it can chew with its scale especially since it ended up being so short but with Masasumi Kakizakis recognizable confronting art style it does give what little there is some impact.
