⚠ [MAJOR SPOILERS ALERT] ⚠

I have warned.

Here is a list of random arguments (not necessarily very important or concrete, so I'm not imposing myself to be honest here 😂) for Eremika.
This will just be things that cross my mind, please don't give a lot of importance to this. My real arguments were in the previous parts 😉
I will use this one to put all the arguments I find on Internet or by myself. Don't hesitate to give me yours!

If you want another opinion of an Eremika shipper who says what this ship can happen, you should check this profile: 22angialys

1- Eremika is objectively the ship that is the most likely to become cannon. (For the important characters) I think nobody can deny it. Actually they will though. Eremika can be criticize, but other ships don't have as many evidences than this one...

2- In AoT Junior High, Mikasa's love is clearly shown. This little show is great to understand the characters' personalities like they are at the beginning.

3- This scene:

#icryeverytime
Seriously, I can't help but think to how Mikasa could have felt at this moment...

4- Eren feels guilty for hurting Mikasa in his titan form. Just look at his eyes in the Courtroom scene when he learns it.

5- Mikasa has short hair just because Eren suggested it. (sry Jean 😂)

6- Mikasa was actually able to calm Eren with a simple touch. Almost no one can calm him except her.

7- Eren was worrying about Mikasa's broken ribs in the manga. He said sorry, as if he should have been able to avoid this. Sadly in the anime this scene disappeared and Mikasa was like "broken ribs? Don't give a f#ck". Seriously, she should be laying in a bed but anyway. I would have loved to see this scene but they rushed the episode after the Coordinate activation to end the arc and the episode on time.

8- The first ending is all about Mikasa and Eren. You can listen to it and read the lyrics:

It's quite meaningful... The moment where the scarf hides Mikasa's face and after that she has grown up... Maybe I'm wrong but this scene could represent how Eren made her become what she is now.

9- When Mikasa thought Eren was dead, she was giving up. She was ready to die because he did. The only thing that keep her will to fight is Eren. After his death, the only thing she would have lived for is her memory of him. She also stood back because of Eren who told her to fight. The only purpose of her life is Eren.

10- It's always hard to proof that a character loves another, especially in a story which not based on love first. However, the fact is Eren doesn't show any interest in other girls (nor boys). Except Mikasa, he doesn't have lots of relationships with other characters. Maybe Historia, but after what happened between them I think their relationship is just friendship (like Historia said). They accepted each other as friends: Eren accepted the "real" Historia who lives for herself, and Historia accepted Eren even when she believed that his death would have been a good thing. So Eren's strongest relationship is with Mikasa.

11- When Eren got eaten by a titan, Mikasa felt it, as if she had a special bond with him. Mikasa's senses are tingling ...

12- Jean gave up on Mikasa because he knew he has no chance when he saw her with Eren. I mean he stopped trying to approach her directly even if he still has feelings for her.

13- Armin ships Eremika!
#arministhebest

14- There are not a lot of other possibilities than Eremika. Other ships with Mikasa are obviously not canon, others ships with Eren... are probably not going to be canon. It doesn't necessarily put them together, but what else could happen? If they don't die... Mikasa will probably try to "date" Eren. Don't forget that we are in a story, and what could me more beautiful than Mikasa finally accomplishing all her wills with Eren? Finding the beauty in this cruel world? It would be so bad if she just gets heart broken.

15- I think I don't have to proof Mikasa's love now. But still, if you pay attention to Mikasa's quotes, it's all about Eren. Always. She doesn't care about others. With Mikasa, all is always about Eren. Even her famous quote (This world is cruel, but it's also beautiful) refer to Eren. She is always calling his name, she is always looking at him. People that doesn't like Mikasa say that she's obsessed with him. And.... Yes, that's totally true. But I personally find this inspiring: Mikasa knows what can bring her happiness, and she is not ready to lose it.

16- Naughty Eren 😏

17- However, the previous scene shows that he worries about her even for some little things... Is that something he would have already done before or is that a sign that he has already started to evolve?

18- Mikasa is blushing when she talk to Eren in chapter 50. (It's cute... The straight cold face Mikasa is blushing)

19- She also blushes when Ian calls Eren her boyfriend. She doesn't want to admit it, but her feelings are pretty obvious...

20- Sometimes, when Eren is not with her, Mikasa put her scarf on her nose... It's a bit sad but she often does this when she needs some comfort...

21- When they return to their house in Shiganshina, they say nothing to each other but it's really emotional. The two facing their past... It remind us what they went through together. And they looked at each other, and Mikasa put her hand on Eren's shoulder... Barely speaking, they both know how each other is feeling. Really emotional.

22- When Eren hit his own face, when he (implicitly) said he wanted to change... He did it just after looking at Mikasa. I don't know what he thought but anyway looking at Mikasa made him regret some things he did before. Maybe when he was mean to Mikasa or something?

23- This is not really about Eremika, but... When they learn about Ymir's curse... Eren is so serious, he accepts his fate without showing any emotion... This is the current Eren, the one who grew up. He is really serious, maybe a bit sad and pessimistic, but he is not dominated by his emotions, he always think twice, he knows what they will have to do and go through to finally be free... I saw people that doesn't like Eren because of his angry personality (even manga readers). It annoys me because they don't get what is interesting in his character. He changed. Do you ever see Eren saying "I will exterminate them" after season 1. No (or I don't remember). With his cold blood, he is really strong. He just destroys Reiner in Shiganshina battle. You know I think he will look really serious and smart after the time skip. It's just we haven't seen his evolution enough so far. So with this evolution I wonder what he will do with Mikasa's feelings, because I'm sure he will realize them (if ever he hasn't realized it before, like when she said her declaration)...

24- When Mikasa learns about Ymir's curse, she is so desperate... She can't believe it. I understand her... Isayama don't you dare killing Eren! She always wanted to protect Eren, but... She can't fight against a curse. This is so sad... Now go read this book: "A love against time".

...
What?
No, I was not auto-promoting... 🙄

25- Mikasa looks at Eren in the first opening. In the OVA based on Jean, the opening changes: he takes Eren's stead and he looks at Mikasa, who doesn't look at him. The gazes obviously show love feelings.

26- Mikasa is the second most important character in AoT... I mean that she is the second main character just after Eren. When Eren is not here, she is the main character. For example when he got eaten, or when was captured by Reiner and Bertolt. However her rule in the story is not so important... Except the fact that she is a particularly great soldier, her only importance in the storyline is her relationship with Eren. Does it explain why she is a an important character? I don't know but it would mean that she is important. And if she is important, her feelings for Eren are important, because it's what characterize her. Since her feelings have no real importance in the plot (in the plot, not in the story), I wonder if this is not because she will get more importance later. For example if her relationship with Eren evolve, and make that it would be important for the plot... Just a thought that crossed my mind.

27- I heard Anti-Eremika saying some things against it, and, again, about the fact that they are "siblings". I read somewhere that the fact that Mikasa is adopted is just an excuse for us to ship Eremika even if they are siblings. I want to clarify some things:
When we learned that Mikasa was saved by Eren when she was nine, it didn't give us an excuse but a reason. What we learned then is not that they are not really siblings, but that they are not at all. And also that their relationship has beautiful and meaningful origins that explains Mikasa's behavior with Eren... This is the base of Eremika ship.
Let's take an example... I don't know if you watched or read Sword Art Online, but let me tell you something. The main character Kazuto and her sister always lived together, and none of them knew that Kazuto was in fact adopted. Later they both learned the truth and Kazuto's sister fell in love with him. This is incest for me, because they were both raised as siblings and developed a brotherly relationship. The only difference with real siblings is the genes that are different, but in their mind they are siblings. So then, the fact that Kazuto was adopted could be an excuse to ship them (and I think that it is definitely an excuse to justify Kazuto's sister's love which is clearly incest)
Here is the difference with Eren and Mikasa's relationship. Mikasa and Eren were not raised as siblings. They both know that they are not siblings, that's why they are the only ones who can decide if they want to become siblings or not. And they decided that they won't be, calling them siblings won't change that fact. Thinking that Mikasa's "adoption" (it's wrong btw) is an excuse is thinking in the wrong way. If you think that it means that you can't accept that you were wrong when you thought that they were siblings and you didn't understand the deep meaning of the scarf scene.

28- Season 1 episode 25: Mikasa is holding Eren's hands. SO EMOTIONAL.

29- Also in this scene, we can notice how Jean is looking at Eren and Mikasa before leaving. It's clearly because of his love for Mikasa, and he is sad when he looks at her with Eren.

30- Still in this scene, Eren tells Mikasa how he was feeling, and that he thought about dying. He doesn't tell Armin nor Jean, just Mikasa. He waited for the others to leave before admitting his thoughts. I guess it's not something he would have done before. He confides in Mikasa to talk about his deep feelings, and more importantly he admitted that he had a moment of weakness when he thought he could die... although he was reluctant to admit his weakness before, especially with Mikasa who he wanted to surpass.

31- And when she held his hand and said she was glad he came back, he didn't reject her... That's the contrary, he acted gently and wanted to reassure her.

32- I'll tell more things later :) Don't miss it!

I will add more and more evidences later, so stay tuned guys! You can give all your arguments I will put it here :)
Let's try to have as many proofs as possible!

Thanks for your incredible feedback! 😃
