Y'know, I'm sure someone will want to smack me for saying this, but one of the issues with this set is that there's a lot of images where the boobs aren't big enough. Sakuya's boobs are particularly big, it's kind of one of her things, so to speak.Only Himemaru and, uh, Mitsuru? I can never remember that shrine maiden's name... anyway, only those two compete with her in size when it comes to Rindou's characters.
Dunno why anyone would want to make a Sakuya set and not play off that particular detail.
