Great doujin with a somber atmosphere. I really love this team's works! Does this need the MarisaxReimu tag though? Cover indicates it's a ReiMari doujin but it's more subtextual.

Is there also some sort of plot trend with ReiMari artists lately regarding Marisa choosing to become a youkai magician and outliving Reimu? Beni/poprication and Yonurime had made comics with a similar concept before. Or is there some revelation in canon that hints Marisa is inclined to become a youkai? Last I've heard she still doesn't wanna give up her humanity...

Chap 25 last page from Forbidden Scrollery, that probably gonna happen
