Is this a game or an anime? Cause I think I have seen pics/screenshots that look like both.

And....what is the name of it?

Base +4

I believe this is jutaijima 2 (not chapter 2) in the first one it mentions how 3 girls died and its these 3 because this gyaru apears dead in the first one and no its not a sequel, its either before they died/version where they didnt die but the other 3 did, seing how only the researcher is here

Based on the previous OVAs none of them will actually be shown pregnant despite appearing so on the cover.

Artist tag is wrong. It* should be Butcha-U instead of Mizu

This is a new hentai coming out late April, Its a prequel to the Jutaijima series as seen here https://hanime.tv/hentai-videos/jutajima?r=/hentai-videos/jutaijima-1. I don't know how these screenshots were taken, probably a leak somewhere??
