When late 2018 came, ZUN had to make another Touhou Spin-off game call Violet Detector that is about Sumireko Usami....Uh, okay?
And, it was not a very popular photo-shooting bullet hell game, it had also about fanarts of the game too!
So stop talking crap about Sumireko's glasses that has nothing to do with her in-game design. HA-
