This psychological thriller concerns a beautiful woman, her knack for getting people to trust he, and her motives for doing so. It starts Nakama Yukie as the main protagonist, and she is very good in the role of the enigmatic heroine, attractive and at the same time, a bit repellent.
The first episode gets very close to the problem of setting up a lot of storylines, so it seems like the writer is just throwing out ideas and hoping something will stick. However, the story seems to be quite well paced, and I didn't feel overwhelmed with new information.
I enjoyed the first episode, and was impressed with the hard sub version from Heiwa fansubs, which included a nice bit when the subtitles went out of focus along with the image. Very professional.
I note that the lead actress and producers and directors all collaborated before on Utsukushii Rinjin in 2011. While I don't have time to find that and watch it, Saki is certainly good enough to make me think I may have missed something.
