Alas, she already has a name: Sunoko (栖野子). The one in post #1414139 with the tail is her younger sister, Nonoko (野野子). (I'm assuming the Japanese pronunciations are right, given that they look much more like Japanese names than Chinese ones.)
栖 is just as Japanese as any other kanji, but I'll take your word for it if you say it's meant to be read as a Chinese name. Could you change the tags to reflect the actual reading?
Help yourself while I look into Dan to know how to change tags rather than editing each item individually.
A mass edit requires a moderator or admin to create a tag implication. For small batches it's easier to use a tag script; go to the page listing the posts for the tag you want to remove. From the dropdown box at the top right, choose "Tag script." The background color will change and an entry box will appear below the dropdown. Type what you want to change in this box then click in each image. As an example, if tag1 needed to be replaced with tag2, type in the box (without brackets) [-tag1 tag2]. You can then refresh the page and if no posts show up any more, you've succeeded (as long as tag2 was typed correctly, of course). Make sure to change the dropdown box back to View or else you'll apply tag2 to every post you click on around the site; thus why the background color is changed to such a nasty pink.
