ScarfKasa

ScarfKasa is the cargo ship between Mikasa and her scarf from the Attack on Titan fandom.

Canon
The first time Mikasa started using this scarf was when Eren wrapped it around her when her family was slaughtered, and Grisha was planning on adopting her. Eren told her that it's warm, and she agreed, grabbing it and covering her mouth and nose. From there, Mikasa is seen always using that scarf. Every time someone reminds her of Eren or starts talking about him, she normally grabs the scarf and covers her mouth. She has never seen taking out her scarf from season 1 to 3, only once when Eren was resting and Mikasa sat next to him, took the scarf off her neck and put it in her knees. After Hannes death and when Eren was completely devastated, Mikasa confessed her love to him and thanked him for wrapping the scarf around her.

Things started getting more complicated when Eren was lost from the Survey Corps sight, and Mikasa was getting more worried about him. After Eren reunited with Armin and Mikasa, Mikasa tried to convince him to go back with her by telling him he wrapped the scarf around her, but Eren stopped her and told her she hated her. Later, after Armin and Mikasa were sent to jail, Mikasa took her scarf off.

After all the problems they went through, and finally decided they should fight Eren, Mikasa went for her scarf again and put it back. In the manga's ending, after it was decided that they must kill Eren in his Founding Titan form, Mikasa tightened her scarf to the neck, and decided she was going to kill him. After killing him and five years passed, Mikasa is seen next to Eren's grave sadly, and her scarf was falling. A bird "Eren" grabbed her scarf and put it correctly on her. Mikasa thanked Eren for wrapping the scarf around her.

Fanon
Due the fact that Mikasa is always wearing that scarf and has barely taking it off, this ship became sort of a joke meme. Some fans speculate that EreMika would have never happen if Eren wouldn't put the scarf around her, and now Mikasa is always wearing and remembering Eren thanks to that.

Also some fans speculate that giving an anime girl a red scarf means that you're starting some sort of "love illusion", since it happened somehow with NaruHina, since Naruto gave his scarf to Hinata, Hinata fell in love with him and years later both were married.
