ZenNezu

"I will protect you, Nezuko-chan."

- Zenitsu to Nezuko before falling asleep.

ZenNezu is the het ship between Zenitsu Agatsuma and Nezuko Kamado from the Demon Slayer fandom.

Canon
Before seeing her but knowing already that she was a demon, Zenitsu protected Nezuko from Inosuke because Tanjiro said that she was important to him.

When Zenitsu sees her for the first time and discovers that she's a cute girl, he quickly gets mad at Tanjiro because he thinks that Nezuko is actually his girlfriend instead of his sister. Later, when the misunderstanding is clarified, it is shown that Zenitsu quickly fell in love with Nezuko and tries to catch her attention by running after her or giving her flowers. He's shown to be deeply fond of her even on a short period of time, since on the Natagumo Mountain he refers to Nezuko as "the person he wants to protect" and she's his main motivation to run into the forest, claiming that Tanjiro is a moron for bringing a girl into the danger.

While he fights with his kasugaigarasu Ukogi he mentions that Nezuko is cuter than her. On the Butterfly Estate, Zenitsu is shown talking with Nezuko when she's inside her box.

Zenitsu protects Nezuko by his own initiative for the second time on the Demon Train Incident.

Fanon
This ship is one of the most well-known inside the fandom because of Zenitsu's clear attraction toward Nezuko. A lot of people ships them and wants Nezuko to reciprocate his feelings once she becomes a human again. However, on the other hand, some fans dislike it because of Zenitsu's tendency to like a woman based solely on appearance or the fact she's a girl.

In the fandom, they are portrayed a similar way as in the canon-verse. Usually with Nezuko finally returning Zenitsu's affections. Zenitsu is also notably more gentlemanly and has a more mature attitude towards her, leaving behind his playboyish ways (liking every woman he sees) and ultimately decides to settle with Nezuko.
