‘Kiss x Sis’ is a popular harem, ecchi anime. If you like incest anime, then there’s a high chance that you have watched this series. So if you are looking for other series that are similar on a thematic and stylistic level, then yes, we’ve got you covered. Here’s the list of best anime similar to ‘Kiss x Sis’ that are our recommendations. You can watch several of these anime like ‘Kiss x Sis’ on Netflix, Crunchyroll or Hulu.
9. Aki-Sora (2009)
Let’s kickstart the list with incest filled ecchi romance. After all, that’s what we all are mainly here for. ‘Aki-Sora’ is a fairly popular anime among a certain type of anime crowd. It has fan-service, incest and romance, all bundled up together. But here’s the kicker — it has only one episode since it is an OVA around 21 minutes long. The anime mainly focuses on the relationship between two siblings, Aki and Sora. Though certain kinds of feelings are cute when you are young, as you grow up to your late teens, these feelings for your sibling might get complicated and this is what Sora goes through; he has feelings for his sister. I have no idea why this anime does not fall under the hentai category because believe me, from the very first scene you will get an idea about the sexual content in the series.
8. Akaneiro ni Somaru Saka (2008)
‘Akanerio ni Somaru Saka’ starts off as a normal romance story and with some good moments. But obviously, if it is on this list, then it means that something weird happens. The show initially focuses on two of the main characters — Yuuhi and Junichi. Yuuhi is the daughter of a reputable family. One day, some boys start harassing her, after which Junichi comes and saves her. Later, Junichi learns that Yuuhi is a transfer student in his school and turns out that he is her fiance. Yes! But wait, that’s not the surprising weird part. Yuuhi does not deem Junichi worthy, but to prove his incompetence as a husband, she starts to live with him and his sister Minato. Well, you guessed it now, didn’t you? Whenever you see sisters in any ecchi Japanese media, you can be sure that most of the time, incest is involved and that’s just what happens here.
7. Okusama ga Seitokaichou! (2015)
‘Okusama ga Seitokaichou!’ is a comedy anime with lots of ecchi moments. Though there isn’t any incest in this anime, the situation that the male protagonist falls in having to suddenly live with a girl he doesn’t like gives a bit of a similar vibe to ‘Kiss x Sis’. Believe me, the fan-service in this anime is quite on par with ‘Kiss x Sis’. If you love ecchi stuff, then you might enjoy this. The anime basically revolves around Hayato Izumi and Ui Wakana. Both are running for Student Council President. But even after being a good candidate, Hayato is outmatched by Ui who wins the election dominantly by offering sex-ed and free condoms. But there’s a twist — turns out that years ago, after getting drunk, their parents promised that they would marry. Now, Hayato and Ui have to live together. To keep the plot from you I did not provide the English title for this anime, which is ‘My Wife is The Student Council President!’
