The 9 Most Toxic Relationships in Anime

I’ve been thinking a lot about relationships lately, and it’s amazing how complex they can be! You see all kinds—some really lift you up, others can be surprisingly draining. Honestly, it’s not always obvious right away if a relationship is turning unhealthy. Sometimes, there’s so much love, loyalty, and even sacrifice involved that it’s easy to miss the warning signs—to kind of romanticize things even when they’re not good for you.

What’s so interesting about these relationships is that the harmful patterns aren’t always the same. Sometimes they’re explosive, with yelling, control, and abuse. Other times, the damage is more subtle, showing up as emotional distance, avoidance, and a clear power imbalance. Often, the people involved don’t even realize how much they’re hurting each other, or how easily affection can turn into something destructive.

Light Uses Misa as a Tool and She Accepts It Completely

Right from the start of Death Note, Light is blunt about wanting to use Misa for her powers, and Misa’s willingness to accept this shows how unrealistic her view of the world is. Even when Light dismisses her and is unfaithful with Kiyomi Takada, Misa somehow justifies it as just part of who he is.

Misa is deeply in love with Light, despite knowing he intends to use and ultimately kill her. She’s incredibly reliant on him, willing to give up her friends, her freedom, and even her own life in an attempt to win his affection. Even after Light dies, Misa remains devoted to their connection, and she ultimately chooses to end her life, writing in the Death Note that she wants to die by Light’s hand.

Asuka and Shinji Mirror Each Other’s Emotional Damage

Asuka craves reassurance, while Shinji fears being hurt, leading to a difficult cycle where they both want closeness but struggle to connect in a healthy way. Asuka refuses to be simply a source of comfort for Shinji and believes he can’t reciprocate her feelings or treat her with respect. This ultimately results in Shinji lashing out in anger and physically attacking Asuka.

Shinji and Asuka’s connection isn’t a failed romance; it’s rooted in their emotional pain. When they briefly connect, it’s not a true bond, but a temporary attempt to cope with their inner emptiness. They repeatedly clash, pull away, and misunderstand each other due to their past traumas.

Makima Controls Denji’s Devotion Through Reward Systems

In Chainsaw Man, Makima uses a system of rewards and punishments to control Denji, always reminding him of her power over his life. Because Denji has never experienced genuine safety without a cost, he misinterprets Makima’s provision of basic needs and a sense of purpose as kindness. This leads Makima to fundamentally alter Denji’s sense of self, causing him to rely on her for all decisions and prioritize her happiness above his own.

I watched as Makima systematically broke Denji down, not with anger, but with a cold, calculated approach. He’d started to rely on her for happiness, but she seemed to only use that to hurt him even more – especially after Power’s death, which he witnessed. It was awful. Then, she twisted things around, making him believe he’d actually helped her kill Power, and even that he was responsible for Hayakawa’s fate when there might have been another way. She completely manipulated him, making him question everything.

Re-l and Vincent Turns Connection Into Obsession

Initially, Re-l saw Vincent only as a subject for her investigation. However, she later realizes he’s in love with her. Instead of reciprocating, she begins to manipulate his feelings, using him when it’s convenient and pushing him away when it isn’t. A prime example of this is when she kisses him to distract him while secretly concealing her weapon.

Vincent is drawn to Re-l because she reminds him of Monad Proxy, someone he deeply loved but unintentionally harmed by absorbing her memories. Their relationship is essentially built on Vincent reliving memories of a lost love, while Re-l exploits him for information about the Proxies. The anime Ergo Proxy deliberately leaves it ambiguous whether the bond between Re-l and Vincent is a real connection or simply two broken individuals using each other to achieve their own goals.

Yuno’s Love is Just Psychological Captivity for Yukiteru

Yuno, in Future Diary, takes extreme measures to find love, even killing herself in one timeline to create a new version of Yukiteru. She’s willing to alter reality itself to achieve the love she desires, a love she felt was missing in her initial relationship with Yukiteru. Her diary, which updates frequently, allows her to track Yukiteru’s location, blurring the line between affection and obsessive control.

Yuno goes to extreme lengths to protect Yukiteru, even holding him hostage to prevent other diary users from harming him – she sees him as completely hers. However, Yukiteru isn’t blameless; he manipulates Yuno to improve his own chances of winning the game, creating a very unhealthy relationship. Ultimately, their connection highlights Yuno’s intense emotional reliance on Yukiteru, while he primarily views her as a protector.

Sakura Clings to Sasuke While He Shows Emotional Rejection

Sakura’s intense feelings for Sasuke lead her to accept his mistreatment, to the point where she seems to lose herself in the relationship. Sasuke consistently ignored and belittled Sakura, and she never stood up to him. He was openly dismissive, even calling her annoying after she confessed her feelings. He also used genjutsu on her before his fight with Naruto and tried to kill her several times during Naruto: Shippuden.

The anime portrays Sakura’s devotion to Sasuke as admirable, but it’s actually damaging and unhealthy. Even after they marry and have a child, Sasuke remains emotionally distant and frequently absent, essentially leaving Sakura to raise their daughter alone. Sakura even confesses she keeps photos of Sasuke to remind herself of his appearance, highlighting the emotional toll and abuse she silently endures in hopes of his affection.

Satou Rewrites Shio’s Reality in the Name of Love

In Happy Sugar Life, Satou imprisons Shio in her apartment, falsely claiming the outside world is unsafe. This manipulation creates a complete psychological dependence in the eight-year-old, before she’s able to understand what’s happening. Satou presents this isolation as a form of protection, and Shio mistakenly believes it’s an expression of love.

The relationship between Satou and Shio is damaging because Satou exploits Shio’s naiveté, fundamentally changing how she views love, trust, and what’s right or wrong. Satou truly thinks she’s helping Shio, which makes the emotional harm she causes even worse and leads her to justify abuse – both physical and emotional – as a form of protection.

Ruka Forces Emotional Commitment on Kazuya

In the anime Rent-a-Girlfriend, Ruka experiences an unusual heartbeat, and being near Kazuya causes it to race. She quickly interprets this physical reaction as a sign that they’re meant to be together. However, her actions and attempts to get close to Kazuya come across as needy rather than genuine affection.

Kazuya reluctantly agrees to be Ruka’s practice boyfriend, letting duty take the place of real affection. Because Kazuya can’t make up his mind and often goes along with things that make him uncomfortable, their relationship is built on obligation rather than genuine connection.

Kyouya Shows His Dominance By Making Erika His Pet

The story of Wolf Girl and Black Prince relies on a familiar dynamic: a character who acts cruelly towards someone they secretly like. Throughout the series, Kyouya consistently treats Erika like a pet instead of an equal partner. Their relationship begins because Erika desperately asks Kyouya to pretend to be her boyfriend, but he only agrees if she accepts being treated like his ‘pet dog’.

From the start, Kyouya presents himself as someone who doesn’t want a relationship, yet he still dates girls, immediately establishing him as a selfish and unpleasant protagonist. Erika misinterprets his dismissive behavior as romantic interest, and any rare kindness from Kyouya is falsely portrayed as him becoming a better person.
