I've dug through my shelves and online threads a bunch of times trying to pin this down, and the clearest thing I can tell you is that 'Hinata' as an adult manga title isn't usually one single, officially serialized work by one name-brand artist. A lot of the material floating around under that name tends to be fan-produced doujinshi or one-shot adult manga created by a variety of independent artists and circles. If you have a specific volume or cover image, the artist is almost always credited in the colophon or on the seller page — look for a circle name, an artist handle, or an ISBN/publisher detail.
I know that can be a bit of a letdown if you were hoping for a single-name answer, but it's pretty common with character-based adult works: the title 'Hinata' gets reused by different creators, especially on platforms where artists self-publish. From my own digging, the best bet is to check the book's back matter or the original upload on places like Pixiv or the publisher's page; that’s where the real credit lives. Personally, I love tracking down who drew what—there’s so much great variety among the different takes, and it’s always fun to spot a favorite artist’s style in an unexpected place.
