This is Youko (last name forgotten) from the Yamibou game. Also, the dress she's wearing certainly looks like a "chinadress" when it's buttoned up.

Why am I giving her character name in the comments? Because there's only one picture of her--and it's wasteful of danbooru's storage space to constantly create new, unpopulated tags.

New tags take up a negligible amount of space. A couple bytes, at most.

wouldnt it save more space if you only pressed enter once whilst starting a new paragraph?
thought so!

It saves more space but it also makes it chunky and annoying to read.

Did this actually take place in the game?
