EruRiHan

EruRiHan is the poly ship between Erwin Smith, Levi Ackerman, and Hange Zoë from the Attack on Titan fandom.

Canon
Erwin, Levi, and Hange are all comrades and have great trust and respect towards one another. Levi and Hange are the two people Erwin places deep respect and trust in. They are among the few, along with other veteran members, who he let in on the actual plan involving the Female Titan. When the Female Titan is captured but then swarmed by countless other titans who begin devouring her, Erwin orders all squads to defend the Titan to the death. Following his order, Hange and Levi fight relentlessly.

After Erwin looses his arm in battle and is recovering, Levi is seen in his room. Hange arrives there, too, to discuss important business. Later when Erwin is detained on false accusations of murder, Erwin appoints Hange the next Commander of the Survey Corps. Levi and Hange work together to dismantle the net of lies spread by the government and clear Erwin's name. Levi, Hange and the rest of the Survey Corps have to lay low for a while, but when it vecomes apparent there is no way back, Levi realized there only two ways out, either to flee or kill their pursuers. Hange replies suggesting they do both, and Levi notes that this is exactly what Erwin would say. While they're in hinding, Levi and Hange always find a way to communicate with Erwin without compromising their secrecy, always cooperating and coordinating their every step with him.

Both Hange and Levi advocate for Erwin to receive the titan serum when he is delivered on the rooftop in critical condition. Levi and Hange both fiercelessly fight for Erwin and defend his role in saving the humanity. When Mikasa is ready to strike Levi dead to give serum to Armin, she is stopped by Hange, who arrives at the scene just in time, restraining and preventing her from attacking other comrades. Levi wants to make the final promise to Erwin before he dies, repeating what he said earlier when they were alone, about killing Zeke, but Hange says he’s already gone. After Hange announces Erwin's death, the two look visibly anguished as they mourn him.

As four years go by, Levi and Hange still remember Erwin and often think of him. Levi notices how sometime Hange acts or speaks like Erwin. While discussing their tactic with the Marleyans, Hange directly quotes Erwin, probably without even realizing it, saying that if one doesn't know or understand something, they should go and figure it out, adding Erwin's famous "Isn't that the Survey Corps way?" When Hange and Levi start cooperating with Magath and the Warriors to stop Eren Jaeger's plan, Hange asks Levi if he thinks that their dead comrades are watching them and seeing efforts to save the world. Levi sorrowfully says that they've started "talking like him" meaning Erwin and his constant debacle. Levi frequently thinks of Erwin, and the promise he gave him. He often comes back to the day Erwin died, when Levi made the choice to give titan serum to Armin and to let Erwin rest, thinking it was his "personal felings" that made him take the decision to let Erwin go.

When Hange is ready to sacrifice their life, Levi tells them to “devote their heart”, famous expression mant to rally soldiers into battle and inspire them to give their lives, or “hearts”, for the sake of humanity — it has become iconic due to Erwin’s influence, who never failed to mention it in all of his speeches. After Hange dies, they see Erwin, surrounded by all of their fallen comrades. He reassures them that their sacrifice isn't futile and Hange seems overjoyed to be with Erwin and the rest. When the battle for the humanity is nearing its end, and the power of the Titans is undone, the Eldians reunite with their families. Levi rests against a rock and sees a vision of his fallen comrades. Erwin and Hange are particularly prominent against the rest of the soldiers. Levi asks his friends and comrades if they saw him fighting for humanity, and says that the victory is the result of all of their sacrifices. They salute Levi, and he salutes back.

Fanon
It's one of the most popular trios in the series currently rivaling EreMikaAru. While some fans see Erwin, Levi, and Hange's interactions as romantic, many enjoy their dynamic as platonic friends and comrades. It is apparent that Erwin, Levi, and Hange are the most important people in each other lives, and the impact they all have on each other is tremendous. After Erwin's death Levi and Hange never forget him, and the memory of the relentless commander helps them move forward. It is possible that the only thing, the only objective Levi and Hange have after Erwin's death is not falling short of Erwin's expectations of them, and not failing the responsibilities he left them — Hange being the commander, and Levi carrying out Zeke's execution. Considerig the popularity of EruRi and LeviHan, EruRiHan is a good way to console rivalring parties, offering a peaceful solution to those who enjoy all three characters and their interactions on screen and in manga. Fanfiction and fan arts often depict scenarios where Erwin received the serum, and the three went to the continent together to settle matters down diplomatically without spilling blood.
