As for the concept, it all started with the idea of pitting Hecatia (a good contender for the strongest character in Touhou) against the already so grown-up trio (that I'm afraid might be some of the weakest bosses in the whole series) fighting with all their might.
As you could probably tell, this was a completion (?) of sorts for "Magic of Isolation". It takes place after that story, but entirely turning the conclusion on its head would've felt bad both personally and in terms of scale, so I ended up with this.

This time's new comic.
The title is an album from the band "Yura Yura Teikoku" that I used to be a huge fan of.
These major characters of the stories in this book - the three witches, the already so grown-up trio, the three tengu and the three-body god - were all arranged into groups of 3, so there you go. Of course, I didn't even realize this at the time I was drawing them and it was a total coincidence. Could it have been the three-world goddess' guidance???
Seija is still all by her lonesome, though, which I feel is very much like her. Well, I suppose she had to hang back a bit after getting to go wild in Vol. 3. (not that I won't still take the tasty parts)
I wanted to draw more of Hecatia's troublesome and large-scale nature befitting a Greek god, too. "Magic of Isolation" was already overkill, one might think! But still!!
I ended up making the tweak of giving each body their own hairstyle, but to the very end I was agonizing over whether I should do the same for the "Hell" on her shirt. I decided that doing so would be stretching it and distracting from the story, but...
I'm also worried whether Hatate's thoughtography was actually faithful to the setting. From what I've seen, fan works seem to be strongly split between handling it as simple spirit photos the way I did, and something like "searching for and replicating photos already taken by someone else."
The source material seems to have mix of both, though, so I suppose we can't give a clear answer. Personally I think the latter option is more interesting, since it has its own terms and limits, which is why I have mixed feelings about having used the former option in this story.
Also, the Nimble Fabric turning you completely invisible is a relic of "Babanbabanki" from Vol. 3. (Buddha-Face Banki is from over there as well.)
For whatever reason it just fits so well that I didn't even realize when I was drawing, but when I think about it, isn't that a huge stretch on my part???
