Oftentimes, a manga will write a yandere as either a love interest for the main character or as shock value for the audience. What's interesting is when the yandere is written as not just as a generic yandere, but as a geninuely ill mental person, which is what this manga does. This manga reads like a horror story, and I love it. The main characters descent to madness is very enjoyable to watch, as he discovers more and more of the unpleasant yandere side of his student. He struggles with his paranoia revolving her and her aggressive obsession with him, this being the most interesting aspect of the book.

While the conflict between the yandere and main character was surprisingly interesting and gripping, this manga has very significant tone problems. The first half is, for some reason, written like a hentai. The manga goes through great lengths to show you how sexy the yandere is, and how sexually attracted the main character is to her (although he refuses her advances). This is very tonely jarring from the second half of the manga where the tension between the main character and yandere switches from sexual tension to geninue fear and anxiety on the part of the main character. I think the author was going for a "fatal femme" thing, but it just doesn't work at all, and it takes you out of the plot.
