The protagonist explores both sides of sadomasochism, being predominantly sadistic, and being subjected to masochism against his will. - This detail makes the anime interesting for both sadists and masochists.
Although relatively superficial and poorly executed, the plot is somewhat better developed than most of the anime in the category.
Starting with the protagonist in a position of abuse, and later having his [sexual] revenge, which gives a greater background to his sadistic acts (bringing satisfaction to the viewer)
The plot revolves around a magical notebook (probably based on Death Note) where written sexual fantasies become reality, which is interesting, original, a bit funny but acceptable.
is not so bad, but the art is not as good as it could be.
I personally do not think that this hinders the use of content, it is average.
Although animation and art are not so appealing, history and sexual fantasies are explored well enough to provide viewers with pleasure.
In the end these two characteristics are balanced leaving the anime with a good final note, but not so good.
It is possible that the next episodes will be much more interesting, since there are vast possibilities in the sadomasochistic world and the plot is on the right track.
