Disclaimer: Not rated by me (except for the last one), but by Anime site TWI-ANI
In real life, relationships between sisters and brothers are a big taboo. However, in anime , it seems to have become a trend in recent years (like some people were discussing the other day over here) with titles like OreImo and Yosuga no Sora and the proliferation of Imouto routes on Date-sims.
Terms like BroCon (Brother Complex) and SisCon (Sister Complex) are becoming as mainstream as Tsundere and Yandere so Anime site TWI-ANI decided to rate some of them.
Some of the pairings below may not be related by blood, but I'm not saying who to avoid spoilers.
While some people I know are on the verge of dropping this one because of Miyuki, there's no doubt that Tsutomu Satou's best selling light novel series is one of 2014′s most hyped new anime series and so far, it has provided plenty of moments between the Shiba siblings which make you wonder what sort of relationship these siblings really have.
In most places incest is considered a taboo in modern society, and Yuzuki Kurebayashi from Selector Infected Wixoss just wants to break that taboo and have her wish granted – to be in a relationship with her brother Kazuki without society looking down on them. When you look it that way, she could learn a thing or two of Miyuki.
The Saboteur Siblings, Akari and Toru Acura are extremely skilled when it comes to fighting, especially when protecting their employer, Chaika. It is pretty clear that Akari has one huge brother complex and gets very jealous every time Toru and Chaika get closer to each other and she can be a little Yandere at times too. Toru on the other hand is a bit dense (is he?) and cannot see his sister's feeling for him.
The brother-sister duo known as 『 』or "blank" is comprised of Shiro and Sora, and while they are most certainly really really close to each other (to the point that they won't mind going mouth-to-mouth in order to win a game), their romantic relationship is a bit vague as both see each other as one half of a bigger entity, but of course the sister gets jealous in very smart ways.
The story with the sibling pair I though was going to be rated as "unhealthy" under the Youth Healthy Development Ordinance. *Spoilers begin* They have shocked the world when they actually made love on national TV *Spoilers end*. The show certainly is controversial and it just makes Haruka and Sora one of the most legendary siblings in anime history.
Akiko Himenokouji has one serious case of the brother complex as she would stop at nothing to marry her brother and does not seem to mind that society thinks ill of such relationships. Her brother Akito on the other hand just thinks she is annoying (ehmmm.....right, for all those who watched the Anime there are some interesting hints thrown in there)
I can spoil this one because this is from 2004 and I'm pretty sure no one is going to watch this (which is licensed in the US by the way). They may not be as legendary as some others but they also did " that ". Their relationship got so close that they eventually fell in love with one another and then made love, breaking one of society's biggest taboos.
Anime site SGCafe, propose some other famous pairings on their own
First we have what is probably is the most (in)famous pairing in Anime in recent times Kyousuke and Kirino Kosaka from OreImo who actually had a relationship with each other.
Others are Nao and Shuusuke Takanashi from Oniichan no Koto Nanka Zenzen Suki Janain Dakara ne or Minato and Junichi Nagase from Akane-iro ni Somaru Saka or the sibling love triangle of Ako, Riko, and Keita Suminoe from Kiss X Sis.
Now the next one is from me
This is some kind of subversion since in this relationship the Sister is the older of the siblings, but man what an interesting older sister, outspoken and passionate, she immediately falls in love with Tomoya and is overly protective of him. She sometimes acts like a stalker, and is jealous of any girls that show affection to Tomoya, but acts like a big sister when the situation arises. Also in the words of Koda89 "That triangle mouth!"
So what do you think? Have a favorite pairing?, Are you annoyed by Sister-Brother relationships? Let me know in the comments below
