‘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!’
6. Oniichan dakedo Ai sae Areba Kankeinai yo ne! (2012)
Look, after watching anime for thousands of hours, we might not know Japanese but we have a pretty good idea about lots of words. For instance, let’s look at the title of our next anime — ‘Oniichan dakedo Ai sae Kankeinai yo ne!’. We will instantly recognize the word Oniichan and since the anime is on this list, we can again deduce that it contains enough incest to cripple you for life.
The anime revolves around two siblings, Akiko and Akito. Their parents died when they were young and they lived with different foster families after that. Now, they are reunited and they can live together. Very touching story, right? Well, the ‘touching’ part here has a different sense when you watch the anime. Turns out the sister Akiko has a brother complex and wants him to look at her in a ‘different’ way. Her determination to get her brother to like her beyond that of a normal sibling relationship becomes stronger when other girls move in with them. Trust me, if you like ‘Kiss x Sis’, you will like this anime too.
5. Kanokon (2008)
If ecchi, harem themes are the ones which made you gravitate towards ‘Kiss x Sis’, then here’s another one for you — ‘Kanokon’. It does not have any incest but there are plenty of lewd moments to keep you going. The protagonist of the anime is Kouta Oyamada. He has a weird problem when it comes to females. He keeps on attracting female animal spirits. So, if you like looking at fox girls and other pretty Animal Youkais, then this anime will be quite entertaining. Kouta lived in the countryside and now he wants to move to the big city to start a new life. But here too his trouble does not end as he starts attracting the attention of fox spirit Chizuru and other Youkai.
4. Cyclops Shoujo Saipuu (2013)
Look, if you want a great romantic plot, then ‘Cyclops Shoujo Saipuu’ is not going to cut it for you. But if you want incest comedy with lots of lewd moments, then voila! It becomes an entertaining show. The protagonist of the anime is Saitou Fuuka. After puberty hits her, she becomes tall, pretty, and well-endowed. But now when she shows affection for her brother, it freaks him out. Why, I hear you ask? After all, it is just a sister being affectionate towards her brother, right? Well, this anime wouldn’t be on this list if it was the case. When Fuuka was a child, she said that she wants to marry her brother. Now, she wants to follow through that promise. Well, you wanted incest, and you got it. By the way, the word Cyclops appears in the title because Fuuka’s hairstyle allows only one of her eyes to be visible, giving her that nickname.
3. Shinmai Maou no Testament (2015)
This must be one of the most popular anime on this list. This series is big among the ecchi, harem-anime loving crowd (basically, everyone). This anime has lots of fan-service and believe me, it has worked hard on boob-physics. ‘Shinmai Maou no Testament’ is about a guy named Toujo Basara, who gains two step-sisters after his father suddenly remarries. But the plot does not end here. Turns out the sisters are demons and one of them is the daughter of the former demon-lord. Unfortunately, Basara belongs to the hero clan who are anti-demons. But he promises to protect his sisters at any cost. What follows is lots of action, though most of it is limited to Basara playing with big-breasted female characters (not that I am complaining!).

2. Yosuga no Sora: In Solitude, Where We Are Least Alone. (2010)
‘Yosuga no Sora: In Solitude, Where We Are Least Alone’ is another incest anime with lots of sex. But bear in mind the stuff that the anime deals with is deep and heavy. It isn’t fun and entertaining in the sense that the other anime on this list are. This is a serious anime with lots of drama. Actually, the source of the series is a visual novel of the same title, which is great since most of the characters end up getting their own stories.
The anime deals with siblings Haruka and Sora, who need to start their life afresh in the countryside after their parents died. It is here where the complications start. Sora loves her brother and after her parents died, her bond with him strengthens. She wants to live with him and starts thinking about incest. Haruka, on the other hand, cannot keep his male part in his pants as throughout the series, he beds different girls. If you want a serious drama with lots of sex and incest, then go for it. The anime has a total of 12 episodes with each episode being 25 minutes in length.

1. Oneechan ga Kita (2014)
I came across this anime while I was doing another list. It was only 36 minutes long, so I decided to binge it. Binge it? How can you binge something that is just 36 minutes, you ask? Well, you can if those 36 minutes are broken down into 12 episodes of 3 minutes each. Tomoya Mizuhara’s dad remarries and thus, he gets an older stepsister named Ichika and when there’s Oneechan (a Japanese word for sister), there’s a scent of incest. Though the series is not outrageous like ‘Kiss x Sis’ or ‘Aki-Sora’, it does have incest elements. The show is nevertheless very entertaining, despite being short. Ichika’s overwhelming love for her step-brother is what makes the core of the anime.
