Now we need an underwater themed Touhou game... (even if it could be hard since... aside of the amabie and wakisagi and nitori, i don't knw if there's more underwater youkai, and a seetting could be hard since A) Gensokyo doesn't have a sea/ocean, and B) it could be hard to do an underwater city that isn't already Atlantis, but then again, i'm sure Zun could try to do a setting based on it, i mean, there's the Beast Kingdom in Hell, and a space noah's ark in the cd dramas, soo i'm sure that an underwater city (or temple, or anything, maybe even a submarine) couldn't be that hard to do, right?)
