GenZen

GenZen is the slash ship between Genya Shinazugawa and Zenitsu Agatsuma from the Demon Slayer fandom.

Canon
Genya and Zenitsu are both members of the Demon Slayer Corps. The two are first seen together during Final selection. The two are standing near each other before the Selection starts, but do not speak to each other directly throughout the proceedings. Though, in the manga, Zenitsu is seen holding onto and caring for Genyas crow after the latter had hit it away.

The next time the two are seen together is in the Hashira training arc. During this, Genya tells Sanemi about how he’d been eating demons in order to fight in the corps. This leads Sanemi to try and blind his brother, only to be stopped once Tanjiro pushes him out of the way. Whilst confronting Sanemi for attacking his brother, Tanjiro calls on Zenitsu to get Genya to safety. Zenitsu grabs onto Genyas hand and tries to run away with him. Genya doesn’t seem to remember going to final selection with Zenitsu during this given the fact that he asks Zenitsu who he is, followed by asking to be let go. Zenitsu responds by explaining how they needed to run away since there was a fight, calling Sanemi a monster while doing so. Genya stops and punches him in the face for insulting his brother, ending the interaction.

Despite the previous encounter ending poorly, we see through Kanao and Muichiros flashbacks that Genya and Zenitsu both hung around in the same friend group. This likely means that they at some point had made up and become friends after the altercation.

They are both seen fighting in the infinity fortress, with a similar theme of connection to their brothers. Zenitsu kills his brother, Kaigaku, ending their relationship after he had become a demon. Genya had reconnected with his brother in the final moments of his life after fighting Upper Moon One alongside him.

Fanon
While GenZen is still a rarepair, it is one of the more popular rarepairs for both Genya and Zenitsu both. However, the ship is still often overlooked due to more popular ships such as NezuZen and GenMui.

Fans of this ship often draw comparisons between in the two with how they both have mean older brothers they want the respect of, and how neither of them were able to master a breathing style. The fans of the ship also tend to make jokes regarding the height difference between the two.
