So, I could be wrong, but I'm pretty sure this is actually a mis-tagged image of Hong Meiling (a character frequently drawn by Neko Majin, whose name in Japanese is often rendered めーりん.) I understand that the image comment reads off as 夏(Natsu)めーりん, sounding like Natsume Rin, but I believe it's meant to be saying this is a summer Meiling picture (夏 meaning summer). As further evidence of this, Neko Majin's Meiling occasionally sports a star tattoo similar to the one shown here, such as in post #1629422 and post #1695674. It's also not uncommon for him to give her pointy ears, such as in post #1332547, post #1731894, etc. I feel unless there's some compelling reason otherwise it should be retagged as copyrights Touhou and character Hong Meiling. Once I figure out how, I'll also go ahead and add translations to the image (when I hit click the note boxes I draw, I can't seem to type anything in.) It will say Rashguard + Bikini, and I'll translate artist's commentary as Summer Meiling.
