LeviHan

LeviHan is the non-binary ship between Levi Ackerman and Hange Zoë from the Attack on Titan fandom.

Canon
Levi and Hange share an extremely close bond based on understanding and trust. They first met in the year 844. Hange is highly impressed by Levi's battle skills and displays great enthusiasm to learn more about their origin. This made Levi quite surprised since Hange was the first person to approach him in such an exited manner from the survey corps. Despite Furlan prompting him to socialise, Levi does not give Hange a real answer and instead pretends to be tired.

In the "Isle's Notebook" OVA Levi loses his temper with Hange after they endangers Oluo's life. He picks them up by the collar and scolds them for it, calling them a "four-eyed bitch". When they jokingly plays this off, Levi throws them back to the ground in fury and stares down on them.

Before one of their scouting missions Hange jokes that Levi wouldn't have so many fans if they knew he was such a clean freak. This scene is extended in the anime with Hange getting excited over the thought of meeting an abnormal and then Levi grabbing Hange's hair, turning their head to face him and teasing that he has already spotted one.

While Levi and his squad are drinking tea, he predicts that Hange will have their hands on Eren in no time, at which point Hange bursts in. Levi is then the first to stand up and leave when the topic of titans comes up.

When Hange calls in Levi to discuss the spoon disaster, Levi asks them if they had been taking a very long dump, to which Hange jokingly admits to.

The two of them are seen observing Annie's crystal together in the finale of season 1. When Hange is later investigating the piece of the crystal they recovered Levi comes to get them and hurry them up, despite his poor physical condition. On the carriage Levi teases Hange for having such a boring hobby as playing with rocks.

After Hange reveals their hypothesis of titans being humans, Levi accepts it as the truth and seems gravely disturbed by it.

During Eren's hardening experiments, Levi tries to calm Hange down by explaining the futility of shouting at Eren in his current state. He then asks if they should punish Mikasa for disobeying orders. Later when Levi is having trouble articulating himself to Eren and Mikasa, Hange steps in to 'translate' what he is trying to say.

Levi apologises to Hange after he fails to protect three members of her squad from Kenny, to which Hange smiles at him. The two of them later work together to kidnap Djel Sannes, torture him and fool him into helping them. In the anime, when Hange kicks over a table out of anger, Levi is the one to walk in on them. Hange says there was a cockroach, to which Levi replies their kick must have blasted it to bits.

Levi trusts Hange to plan out their break-in on the Reiss Chapel. On this mission Hange is wounded by one of Kenny's subordinates. This shocks Levi, who orders Armin to look after them and take them out to safety immediately. In the anime he instructs Armin and Moblit to take Hange and find a way out.

During the Battle of Shiganshina Levi and Hange are shown standing back to back with their swords drawn. Later during the mission, when Bertolt transforms, Levi worries for Hange and their squad. When Hange shows up to pull Mikasa off Levi, he appears very relieved at their survival. Together they watch Erwin pass away peacefully, leaving the two of them as the only remaining veterans in the Survey Corps.

When Hange questions Eren about talking to himself, Levi tells Hange to leave it alone and says he will explain it to them later. Hange uses Levi's explanation of Eren going through a 'phase' later in court. A chapter later we see Levi and Hange together having a conversation with journalists, Roy and Peaure.

A year later, after finally making it to the ocean, Levi tries to discourage Hange from touching the seawater because he worries it might poison her. When Hange is welcoming the Marleyans and trying to earn their trust, Levi is next to them explaining that their plan is clearly not working. The two of them are later seen having tea with Yelena and Onyankopon. In this scene the two are shown communicating with each other using only their facial expressions, demonstrating the deep level of familiarity and understanding between them. Levi and Hange are later seen, once again, sitting next to each other in court.

In chapter 126, after Levi is critically wounded by a thunder spear explosion, Hange finds him and tells the Yeagerists that he is dead in order to prevent him from being shot. When the Yeagerists' attention is diverted towards Zeke, Hange jumps into a nearby river with Levi.

Hange tries to heal Levi's wounds, and while he sleeps they sit next to him. Hange talks to Levi believing he can't hear them, and says they'd like them and Levi to stay there together without having to worry about Marley and Eldia anymore, to which Levi does not directly deny to even though he could hear them. This could imply that in Levi and Hange's ideal life, they both are included. When Levi gets up, he thinks realistically and says "if we keep running and hiding, what will that get us?" Hange softly blushes from embarrassment when they realise that Levi heard their inner monologue. While Levi was asleep Hange made an object to pull Levi along due to his injury. When he notices the object he says "I know you...you can never stay out of action." This shows how much they both truly understand each other.

Before sacrificing their life, Hange says goodbye to Levi, saying that they feels their time has come. In response, Levi tells Hange to dedicate their heart--for the first time ever since he joined the Survey Corps. While Levi and the others are safe on the flying boat, Hange has just died: in Levi's eyes there is a great sadness following the death of his friend. Levi greets Hange for the last time, telling Hange that he'll meet them again soon, and telling them to watch him and the others from above. Additionally, in chapter 136 when Levi is thinking sorrowfully about his memories with his older comrades, Hange and Erwin specifically appear in a separate big panel together where Hange is seen with a cheerful and bright expression in Levi's memory.

Behind The Scenes
In Hange's character interview they made the implication that Levi knocks them out and forcibly bathes them.

In an event SNK The last exhibition many merchandise got announced you can buy there. You can chat with Reeves Company too and ask for recommendations. Due to a leak which later got fixed by the staff, Reeves Company showed two shampoo´s for Levi and Erwin already too early. Fans were confused since these two products are not listed on the site yet and asked about Hanji shampoo if it exists and if they could trigger the Reeves Company to leak more too early. (It was not fixed during this time the people tried this.) We did not got a shampoo revealed as image, however the Reeves company answered:

“This is a hair care agent for Commander Hanji, ordered/made by Captain Levi. It has a powerful cleaning power that makes [uncleanliness] go away. Levi uses it, … all else is off record. By the way, it can also be used to clean the toilet. ”

In a smartpass AU called "Shelter from the Rain Vol. 01 Levi & Moblit Berner" Levi tells moblit to take care of Hange as Moblit is always by Hange’s side. In another smartpass AU called the "The Library That’s Covered In Dust" Levi tells hange that their life is important and saves them when a bunch of books were going to fall on their head, He also tells them to change their shirt as it had become see through because was soaking wet from the rain. These smartpass stories are canon, as they are written by Isayama. 

In official AOT game, AOTTACTICS, Petra was teaching Armin to make chocolate and Levi remembering that Hanji was whining about wanting something sweet so he made chocolate for them on valentine's day.

Hanji said that even if Levi’s words are rough that doesn’t reflect how he truly feels.

In the official Junior high manga, Levi and hange are childhood friends and neighbours.
