https://myanimelist.net/anime/35413/Imouto_sae_Ireba_Ii describes the show as This is the story about the daily life of a young siscon novelist, Itsuki Hashima with his perfect little sister Chihiro, the genius illustrator Nayuta Kani, his best friend Miyako Shirakawa and some insane partners from his publishers.
So why is the show censored? Why does it not feature full nudity? Why does it even exist in this form?
Is this like some game of thrones shit where people watch softcore porn and say "eh I watch it for the plot"? It cannot be since that show also features gore, some attempts at politicking, dragons, armies, landscapes, costumes. This show is just "here's a guy walking in on his nude sister, btw we can't show you the nude sister but we can show you 80% of her body". What is the fucking point?
Another thing is that people dont watch this show in public or discuss it publicly, 100% of viewers watch it in their rooms/homes, alone, so showing full nudity wouldnt be a problem at all.
