EreYumi

"I'm begging you... I can't put faith in you if you keep talking like some stupid kid."

- Ymir mocks Eren

EreYumi is the friendship between Ymir and Eren Jaeger from the Attack on Titan fandom.

Canon
At first, Ymir and Eren didn't know each other very well, which led them to mistrust each other, after the two were captured. Initially, Ymir kept her distance from him, and simply looked at him as he woke up. Eren attempted to turn into a Titan, although was stopped by Ymir, who explained him the situation and showed him the Pure Titans laying around. She then rested her arm on his shoulder and showed him the two stingy bastards who were in front of them.

Eren wondered how much Ymir knows, and how she got her Titan powers, leaving her as an extremely mysterious person from Eren's point of view. When Reiner's personality switches, and explains how he should get promoted. Eren starts yelling at him, only for Ymir to stop him and explain what he's saying. Eren asks Ymir who the enemy is, and as Ymir starts to reply, she is interrupted by Reiner, who talks about Historia. The question is later on answered by Hange, who says that the enemy is humanity itself.

After the conversation between Reiner and Ymir, and how they want to save Historia, she refuses to talk to Eren, and waits for nighttime. When the Scouts come earlier than planned, Bertolt goes over to Ymir and asks her how much time she's stayed as a Titan. Ymir replies with 60 years, and calls it a living nightmare. This conversation is still remembered by Eren, who writes it down and brings it to Hange.

Even after Ymir's death, Eren still mentions her to Historia, and how she must feel disappointed about not being able to save her. It is also said that he attempted to perfect his abilities to go save her, and even apologized to Historia for it.

Fanon
People have noticed how similar Eren and Ymir are, and usually use this to compare Eremin and YumiHisu, ships that both have a hot-headed, Titan Shifter, and the other being sweet, petite and somewhat physically weak. While their interactions were limited, their friendship is somewhat popular. EreYumi has a small number of fanworks on the het side, and on the gen side. Overall, it is Ymir's third most written ship, being behind YumiHisu and NanaYumi.

There have been fan theories of Ymir and Eren being related. A few fans have said how Ymir could get along with anybody in the show, and usually use Eren as an example.

As the similarities between Ymir and Eren are visible, it was somewhat believed that they were blood-related in a way.
