I have never read a manga series as good as this one, the characters seemed so real and the story was just so outstanding. For years I've seen this manga on different manga websites but skipped over it because the art which didn't look really good. Then boredom set in and I was willing to read anything to get over it so I decided to give the series a try. I soon got over my boredom quickly and soon become entranced in Saki Hiwatari"s story about seven scientists who all become reincarnated on earth. The story was so good I didn't even notice the old art and soon the art started to become really good. All the characters were really deep and learning about each character's past was so interesting and entrancing especially the pasts of the two main charters Arisu and Rin. I came close to crying many times due to the tragedy of the scientist's pasts, the ending was really good and cleared up all loose ends.I became so addicted to it that I finished the long series in only two days. For those who have skipped over this amazing series because of the art I advice you rethink your choice and read this awesome manga and you won't regret it. :D
