Manga takes place in Gensokyou, the setting for most of the Touhou games. Obviously Touhou games related.
It's story of 3 fairies and their daily tricking to visitor of Hakurei Shrine, getting revenged, and so on.
1 Volume (Complete)






I reviewed the entire Sangetsusei series at length. My takeaway for the largely forgotten "Eastern and Little Nature Deity" is "isn't this Strange and Bright Nature Deity with a different artist?" Answer: yes. Although the available translation is a little shoddy at the start and the art is incredibly sketchy, I quite liked this little manga. It's about three fairies playing pranks/their day-to-day life. It ended early because of the artist's health issues, and honestly this is a series you may want to read AFTER Hirasaka's entries just in case the translation/art are off-putting, but really I think it's a good'n.
