A good story but von much controversy A story that is certainly not for all audiences but that carries a lot of risk.
Reading some opinions about the fact that this anime only focuses on ecchi makes me see that they haven't finished watching it, although I have to accept that there are unnecessary ecchi scenes with the story, the character of Keyaru seems very well done and acts like a complete Joker-style madman, so I don't think there is a problem on the part of the protagonist, with the other characters they are a bit empty compared to the protagonist who is the one who moves the story, without a doubt that without him the story would not have the same impact.
In conclusion, if you are looking for an action story, dark fantasy and a touch of lust, this story is for you, if you ask me if I recommend it, my answer is yes; but keep in mind that what you are going to see is a revenge story with many violent and lustful scenes, if you are not looking for this in a story, I recommend that you do not see it since it can bother you.
