This image is of a frequently-depicted character known as Jenny Burtory (aka Jenny The Bat), who is a vampire (or perhaps a werebat), model, and spy as a character in the Japanese videogame franchise of fighting games known collectively as Bloody Roar.

The image has both a 3-character logo in Japanese script (perhaps 青天壱) and a Roman-alphabet watermark identifying the artist as Aozoraichi. This page identifies five additional names used by Aozoraichi, to include aozoraya, seiten, 青天屋, 青天, and aitayuu. A bewildering variety of web presences are listed, but the one listed as “homepage” ultimately redirects to a page featuring at least two of those aliases in the URL and logo.

This artist is incredibly prolific; one image board includes almost 500 images under the Aozoraichi artist tag. The Jenny The Bat image above is part of a larger series, to include at least five closely-related images (1 2 3 4 5) plus this one:
