Introduction to the analysis and review:
"guilty pleasure" simply is not enough to describe the feeling of watching this peace of cr*p. I felt i worth less as a human being during each episode I watched. The cliché story, the pathetic animation and character design, the ridiculous way the situations developed.. everything felt as the staff was mocking at the spectator. And yet, I could not stop watching. This may be a show for masochists. I'm sure of it. so let's talk about the individual elements:
Story: It is a cheap copy of Eromanga Sensei, the diference is that the main character is a failure, instead of a well succeeded writer, and that the imouto is a real imouto, not a step sister, and she is a good writer, instead of being a good drawer. Exception to it, it's completely equal in idea, but much worse in execution: petite little sister that is shy and have obvious feeling toward the old brother, but only he doesn't realize, they together cooperate to write a light novel, and a lot of other girls that we know that will not end with the protagonist show up more and more in each episode, adding no relevant development at all... the only purpose is to create the feeling of lovecom and love triangle (or quartet, or quintet.. idk), and to have the tag "harem" in it. So don't expect nothing memorable from it.
Art: Do I really have to talk about it? well, i chose to write this, no one forced me to.. so.. It is the worse anime art and animation i have ever seen (no CGI included). I thought it was impossible to be worse than Pierrot's worst naruto episodes, but Studio NAZ has surpassed it. congratulations. And I thought that Hajimete no Gal was the worst that studio could do. I was wrong. deeply wrong. sorry. Just to describe this gore: there is an episode the animators forgot to change the position of the mouth after the head moved, and so the mouth stayed in the air, floating!!! the character designs were ridiculous, completely deformed, disproportional. the expressions were really dead, the only emotion i could feel from it was my own embarrassment for watching it, and even enjoying it.
sound: nothing that caught up my attention. some good seyuu.
character: almost every character is insipid. You can't feel empathy por none of them. the main character that we should feel attraction for, the anime doesn't give any fair reason for us to do so: the imouto. She is meant to be cute. and that is it. it could work if the art made she beautiful, but that's other matter. The main point is that she doesn't have any development as a human being. When we talk about inseki animes, the comparison to Oreimo is unavoidable, and the difference in "how we start to empathize with the character" is overwhelming. Kirino struggles in many things in life and relies on her brother to overcome those situations and grow. During this process the brother and also the spectator falls in love with her. In this anime neither the spectator or the brother falls in love with the imouto. it shows how shallow is the development. The only character worth mentioning is Ahegao Double Peace sensei. She has more plot than any other character, and legitimately makes you laugh. I wish I could say "she saves the serie" but it's not enough.
Enjoyment: That's the hard part. Because everything in this anime should be enough for me to drop it in the first episode. Exception to the "inseki" part. So it went on... and i felt really bad watching it. I felt my neurons were dying, and i was becoming more stupid, and that I was in a no return path. And it may be true. But I don't repent watching it. If not by the anime itself, but as a matter of self knowledge. By watching it I could remember how degenerated i'm as a human being, and that fact is always worth reminding.
Overall I just recommend this anime to the chosen ones that have went down the path of siscon animes and watched every single anime of this genre and thinks that can't go lower. Watch it and you will see you can. good luck
