Also known as: 東方茨歌仙
Touhou official manga mostly depicting the life of the hermit Ibaraki Kasen and her interactions with the world, predominantly Hakurei Reimu and the shrine maiden's somewhat lax (by Kasen's standards) manner of handling her shrine, as well as thinly veiled implications from Ibuki Suika and others that Kasen is, in fact, an oni.
