Itsuki Hashima is a light novelist obsessed with little sisters, strictly focusing on them when he writes his stories. Despite his personality, he is surrounded by a tight circle of friends: Nayuta Kani, a genius yet perverted novelist who is in love with him; Haruto Fuwa, a fellow male author whose work has seen considerable success; Miyako Shirakawa, a good friend that he met in college; and Chihiro, his perfect younger step-brother who takes care of the housework and cooking.

Together, they play strange games, go on spontaneous journeys, crack silly jokes, and celebrate each other's successes. However, each individual must also deal with their own issues, whether it is struggling to meet a deadline or coming to terms with traumatic events buried in their past.

This season of anime was one to look forward to, with popular series like Umaru and Gintama gaining new additions to their story. However there were a couple of new additions that have stood out as well (namely Blend S and Mahoutsukai no Yome). That being said Imouto sae ireba is my pick of this season. The reason simply being because its good at its genre. Compared to Blend S forgetting about the settings of their MC (I can only assume it has something to do with wanting the audience to actually like her) and Mahoutsukai no yome merely touching upon dependence rather than love, ...

Mixed Feelings
Do you like little sisters? Good, because our protagonist Itsuki loves them probably more than you do. I give this anime an overall score of 6, but that does not mean I think it is distasteful. In fact I think that some people will give this anime a 8 or 9, maybe even a 10. This review is a spoiler-free review by the way, but it would not hurt for people who have watched this anime already to read this review too.


I acknowledge how the story may seem non linear at times, but I assure you that this anime actually has an excellent narrative. ...

ImoSae was just as if not shittier than Eromanga.
The only reason I didn't drop it was because I always pick a show every season and watch it precisely because it's terrible to make me feel thankful for the existence of actual good shows.( Previous season it was "in another world with my smartphone". God damn it was bad lol ).

The show tried to force kanikou down my throat and into my heart and it failed miserably.
They went for the trope of the girl who's very "lewd" and always aggressively coming onto the MC but blushes and shuts down when he "unintentionally" comes onto her. ...
