Plot: Two years ago, Ayumu Narumi's older brother, Kiyotaka, disappeared. One of the last things his brother said to him had to do with the "Blade Children."

Art & Animation: B
Music: There are times when the music distracts you from what's going on or being said. (C)
Voice Acting: The main characters' voices don't fit, and Ayumu's, in particular, is flat and uninteresting (C-)
Objectionable Content: Blood, profanity
Other: The anime devolves into a tiring game of cat-and-mouse, giving no real answers to the questions it sets out to solve. However, the manga switches gears about halfway through from your general mystery story to a fantasy/sci-fi epic with a few frightening twists.
Overall Score: Anime - C+ / Manga - B
