EreHisu

EreKuri is the het ship between Eren Jaeger and Historia Reiss from the Attack on Titan fandom.

Canon
In the "Distress" OVA, Eren refused to abandon Historia (then Krista) when she was taken hostage by thieves, and was even willing to rescue her without the help of the others. He did, however, accept the help of Jean and the two of them ended up rescuing her with team work.

Eren openly stated that he liked Historia as a person, a sentiment which genuinely made her happy. Eren’s admiration and respect for Historia only deepened when she defied her father and tried to save him, and also later when she killed her father's titan and took the throne. Eren thought to himself about how strong Historia had become.

Eren spoke fondly of Historia afterwards while he, Jean and Armin watched her scolding some kids on her orphan farm. He then told her she was amazing.

Eren refrained from telling anyone about Dina for an entire year because he feared Historia would be turned into a titan as a result. He also rejected the idea of Historia sacrificing herself for the future of Eldia, and tried to look for further options.

Fanon
Some fans are currently speculating that Eren is the father of the child Historia is now carrying, though, the possibility of this is only very slight.
