Is there any /out/ related anime?

NOT SO FAST
I'm asking about REALLY /out/-tier anime, not "lolis go barely into nature" slice-of-life bullshit like "Yama no Susume"

"Unhabitated planet survive" (pic related) is the closest thing I know because everything happens in a desert island, although it may not be /out/ enough for you.

I thought "Coppelion" would be good in that way but ended up very disapointed
