The 15 Most Screwed Up Sibling Relationships In Anime

List RulesVote up the anime siblings that would have been WAY happier as only children.

There are a lot of anime siblings with screwed up relationships out there. Some of these horrible anime brothers and sisters are trying to kill each other, some are trying to screw each other, and others come from horrendously dysfunctional anime families with terrible parents who make it pretty much impossible for their kids to get along. You'll find weird anime sibling relationships in everything from action hits Naruto and Kill la Kill to emotionally driven shows like Yuri!!! on Ice and March Comes In Like A Lion. Some of these messed up anime siblings could seriously use some family therapy.

    Killua & Illumi Zoldyck From 'Hunter x Hunter'

    Let's be real: the entire Zoldyck family is just a huge mess. I guess that's what you can expect from a family of deadly assassins. But Killua's relationship with his older brother, Illumi, is particularly strange. Although Illumi cares about his brother deep down, he has a twisted way of showing it. He constantly reminds Killua that he's forever destined to be consumed by darkness, and that it's impossible for him to have friends. In order to ensure his survival, Illumi would force him into obedience using his Nen. He definitely takes the role of an overprotective brother way too far.

    Sasuke & Itachi Uchiha From 'Naruto'

    Sasuke Uchiha's primary goal in life is to murder his older brother Itachi. He doesn't care if he dies, doesn't care if he has to mortgage his body to the deplorably creepy Orochimaru, doesn't care if he has to kill hundreds of other people and betray his friends, he only wants to end his brother's life. Why is this so important to him? Because Itachi murdered all the rest of the Uchiha clan, leaving Sasuke an orphan.

    This is screwed up enough, before you start layering on the complications. First of all, Sasuke adored his brother prior to the event, so the betrayal hits a lot harder than it might have if they weren't close. Second of all, Itachi had little choice in the matter. At age 13, he was convinced by a corrupt government leader named Danzo to take out his whole family. Why does he agree? Because if he doesn't, Danzo would have the whole family killed anyway. By killing his family, he was allowed to spare his own life, and that of his baby brother Sasuke. Had Itachi told his family and tried to fight back, it would have sparked a civil war, an option that a teenager with war-induced PSTD isn't likely to go for. 

    Sasuke doesn't learn any of this until after he gets his revenge, so the two never have a chance to reconcile. Thanks for the heaping helping of tragedy, Kishimoto.

    Maki & Mai Zenin From 'Jujutsu Kaisen'

    Maki and Mai are twin sisters who hail from the respected Zenin Family - one of the three major clans in the jujutsu world. Since both sisters possess very little cursed energy compared to other Zenin sorcerers, they were treated as rejects by the clan. Instead of staying by her sister's side, Maki decided to forge her own path and cut ties with the clan. This led Mai to become extremely resentful of Maki as she felt abandoned by her sister and was forced to become a sorcerer. 

    Although deep down both sisters still care for each other, there's a lot of misunderstanding between them due to their complicated family ties. They treat each other with hostility as evidenced during the Kyoto Exchange Event.

    Mitsuki & Yuuya Kanzaki From 'Recently, My Sister Is Unusual'

    Mitsuki and Yuuya Kanzaki are step-siblings. Before we go any further, please realize that this doesn't make them not siblings. Anime likes to use step-siblings to make incest seem less icky, but anyone who's been part of a blended family knows that's bullsh*t.

    Anyway, Yuuya's friend Hiyori was madly in love with him before she died. Now, those feelings are keeping her ghost from ascending to heaven. She solves the problem by possessing Mitsuki, Yuuya's sister, and tries to consummate the relationship using her body. This totally ruins any chance the siblings might have had at a normal brother-sister dynamic.
