It's a very short 30 something page one shot. But it's a nice little read.
The main character is the girl of the story. She describes the sniper as her best friend. Although, they've only just met.
It starts by giving you a warning that the story is difficult to understand it's intentions, but that would only entice most to read further. Which in the end makes reading it seem the opposite of what the reader feels you should get from it. It basically says that the story is too real to be a manga, and that you will not like the ending. It basically wants you
to hate this story.
The pages are drawn with good intentions but it's sometimes a bit difficult to see the whole picture. They seem like they were drawn a bit too quick and not corrected when needed. But accurate enough.
So overall, the way that the story flows to a realistic and harsh ending is fitting, but not satisfying. Which is fine, because that's not it's purpose. This story was meant to be told, and just listened to. Not to get excited over, but not a story you would forget.
I liked it for what it was and what it was trying to be. The only reason I wouldn't give it a 10 is because it's not drawn very well, and it wasn't what I was expecting at all.
It's short enough, that there's nothing to hold against it.
