I have three AU where Zenitsu is a Tsuguko. One he’s Tengen’s, the other he’s Shinobu’s and the last he’s Mitsuri’s. It’s unfair that in the manga/anime, he was the one in the group that wasn’t particularly close to any Hashira or sees one of them with a big admiration (like Tanjiro with Rengoku and Inosuke with Shinobu).
Goddamnit, someone just adopt him.
Everyone should adopt him, he's adorable!
But my favorite options out of these is Mitsuri taking on Zenitsu as a tsukugo. It'd be such a great opportunity to explore their backstories (BOTH of them!) and highlight what they have in common.
Though while Tengen taking Zenitsu on is popular, and I've seen people wanting him to interact with Mitsuri, I can't help but be curious about Shinobu taking him on (in addition to Kanao presumably. I also want them to interact on screen considering they also have quite a bit in common).
