If it’s the art style you like, you might try looking through other pieces by this artist on boorus like Gelbooru/Danbooru. Not every single one is drawn and shaded in that style, but it beats nothing.
I’m sure there are also other artists that share some similarities, but I can’t name any off the top of my head. Let me know if you find some!
Saucenao says it was drawn by Yabuki Kentarou, who is known as the artist for To-Love Ru and related series. It has a post on Yande.re.
Google reverse image search also brings me to an article from ANN that says it’s the cover of one of Japan’s Weekly Playboy mags.
I don’t see any indication that it’s a particular character or person, but I also can’t read Japanese so no idea if there’s anything in the text that would suggest that.
No kidding, that render is on-point. I legit thought this was an actual recording before I expanded the thumbnail. Thanks for sharing.
It’s a niche part of Resort Boin as it was a mini flash game with some voice acting. You can find it on places like H-FLASH (ad blocker recommended) and play it in-browser via the little “run by Ruffle” button. It’s old enough and simple enough that the flash emulator runs it OK.
Alternatively, if you just want other GIFs, you can check out the EH gallery for the series of flash games they released w/o voice acting.
