10 outa 10. I loved the plot. I read this in one go because of it's story. I could've learned a bit more about the characters, The one I'm pretty sure is the main character, is the typically main character dude, but there's a reason that they are the choise for a main character. They are always so kind, they have a past they want to forget, the past reaches him once again when he meets the girl (Aiko). Sadly enough, in this manga, she's not old enough for him. Normally they would come together as a boyfriend n girlfriend. NOPE, not this time. Despite thefact you don't learn that much about the characters, it's a great manga. If you love horror, gore mangas, for gods sake, read this.
