Great revenge story with an amazing soundtrack (made by the same studio that made Saya no Uta's), the extensive descriptions of swordmanship in the middle of fights and the actions and attitude of the Protagonist can be very divisive. Also this is an eroge technically so it has h-scenes (one very early on). Just keep in mind that this is a dark tale that has no problem showing bad characters doing very bad things. But all in all a nice 7 hour-ish experience that entertains all the way through with a great depiction of obssesion and truly living for and by the blade.
