[11][12] MangaLife's Ysabet Reinhardt MacFarlane notes that nothing about the manga portrays the Shojo Beat label on its front cover.

"[14] About.com's Deb Aoki commends the manga for its "stylish, contemporary artwork with lots of bishōnen (pretty boy) eye-candy", its "unconventional shojo story with more suspense, action and violence than romance", and its "tantalizing undercurrent of erotic tension".

However, she criticizes the manga for its "cold, detached storytelling", wooden and unimaginative fight scenes, and a robotic main character.

"[20] Jason Thompson, in the online appendix to Manga: The Complete Guide, commends "Aya Kanno's impressive artwork, which features sexy guys and more than adequate action scenes.

"[21] Conversely, Carlo Santos of Anime News Network criticizes the manga's first volume for its "lazy art, generic action-adventure plotting, and trying-to-sound-cool-and-angsty-but-failing-miserably dialogue".
