okay so!!!!!! this is my favorite manga, i first actually bought it in a store not knowing what it was about at all! and im hooked, no manga has ever made me feel this way? and i love mangas where the main character is actually smart so this just makes it better! this manga not only is a great read but also tought me a lot about the human anatomy haha,, i even like the main villain. The whole thing is just great and i have already bought several more volumes of it, i would recommend reading it to everybody :)
