This time it’s Hakurei Reimu, the main character (?). You can listen to one of her themes here.
While drawing her sleeve-thingies, I had the feeling that I’d drawn something like them before. It’s probably because they’re some combination of Vocaloid sleeve thingies and Inuyasha’s sleeves.
In terms of drawing characters who are mentioned in the “Relationships” section of the previous character on the Touhou wiki, we’ve probably reached the nodes with the most lines coming out of them now…
