Thinking not about similar elements or plot points but rather similar feeling, this semi-official Touhou comic fits the first half of Green Manga, back when the main characters had more drama between them wrt identity and secrets. I don't think it requires much if any familiarity with Touhou beyond the basics of "Gensokyo is a closed off space where the supernatural can still exist even after people stop believing in it. There's a relatively normal Edo period-esque human village but also many different factions of yokai, fairies, etc. All coexisting within their shared confined world. The main characters of Touhou tends to be two human girls, a shrine maiden named Reimu and a witch named Marisa, and they solve problems together to safeguard the peace and safety of Gensokyo. Basically everyone sees them as almost an official yuri couple." This manga is about them in their early years when they still had a lot of unanswered questions about each other and themselves.

(beyond any comparison to anything else, it's well worth getting into Touhou's basics just for the yuri. The Magician Who Loved A Fake, Wild and Horned Hermit, and especially Ladies of Scarlet Devil Mansion are three of the very best manga on this site imo)
Edit: rereading to double check, this recommendation isn't gonna really make sense until chapter 3, where they establish the interpersonal tension. The overarching story about witches isn't the thing like Green Manga, it's the relationship between Reimu and Marisa and how that's shaped by uncertainties about identity.
