Art:
The imouto arc was quite memorable with great character design which speaks to the overall hentai art quality which was tops and definitely by far one of the more visually appealing shows as compared to other hentai which may have off putting artstyle while this style is very appealing to a widespread audience.
Characters
Also unlike other hentai, the characters are quite memorable, even the MC which is usually just a placeholder for the audience member to place themselves in. Due to the circumstances of the possessions the main character is reflected more in terms of thoughts and logic which adds a nice depth to the show. However the lack of interaction with the sister in the first episode leaves an underdeveloped and forgettable character in the sister if the character did not have as good of character design as she did. The first student he interacted with in the second episode was also fairly undeveloped but the second student he possessed showed alot of depth through situational and contextual story telling ('the bunny girl scene') and finally the most memorable character was the goddess. Although it is unfair to say, the fact is that our MC interacted the most and had alot of dialogue unlike most of the other girls giving her the most personality especially with her realizations during her scene showed a substantial character growth moment.
Story
The story of possession or smartphone app powers is not an unknown trope but it has not commonly been animated or more prominently executed in as high of a quality as a show like this. Since most of the situations the MC finds himself in are either unexpected or new circumstances it is very refreshing to have the story told in a manner that the viewer gets to absorb and evaluate the information on their own instead of just being told to them straight up
Overall this show was very well-made with a personally interesting story adapted from one of my favorite sources and was a phenomenal watch with pleasant art work to accompany it
