Sometimes unbelievable but still unbelievably entertaining for me
IMO its strength is in its adult themed dark psychological, that portrays its large cast of weirdos that you might encounter in dark corners of society like obsessions, SMs, suicidals, personas, etc. Then it adds in some elements of psychological emotional dilemma when right or wrong is greyed. Then being adult themed, it also contains sexual scenes, nakedness, slavery of course and gore or torture to some extend.
The plot has a lot of nice twist, but the battles are generally rather simple mind games. Animation and character design are decent, and I actually took a liking to most of characters.
Sure some scenes are unbelievable (yes the dog), but nonetheless overall it has given me more than adequate entertainment and the plot ended up nicely. I am glad I watched this. Recommended for adult and dark theme enthusiast at 7/10
