This manga is very good but the only thing I hate is the tragedy. OKAMOTO Lynn seems to only like sad endings, like elfen lied, especialy when you know the end when you start to read it like Grave of Fireflies. Personally, it's frustrating. I want to watch or read because it's good and want to know what's going on and not know how it ends at the beginning. And also tragedy in the story is Ok but having the heroe(s) die... It's disapointing.
