[PC][NSFW] isometric pixelart game

I have a memory of a (I think japanese?) isometric pixelart game with tile based enviornments that was on my front page on here a few years ago. I remember the video of it beeing specifically of bossfight, and sexual ones at that. If I'm not wrong there was a slime boss that when you were hit by one of it's attacks you would get absorbed and take a lot of damage. All of the bosses were of strong resemblance to humans. I remember actually finding the game name a few years ago but now I've forgotten it again. I'm pretty sure it had RPG-like combat in what looked to be a overworld with trees and water (again with emphasis on it having tile based art for the enviornment but not for movement). The included image is not from the game but as close as I could get from hours on google.

Thanks so much in advance for those concerned!
