Some very minor anime 'dream sequence' full-body nudity in the final episodes, but no details are shown (not even breasts)... just body outlines in a non-sexual situation.

One very brief scene played for comedy shows the bare backside of an old man in a costume-like space suit. He's wearing a "sumo" type loin cloth.

One character is injured in an accident and later spits up some blood. No other violence is depicted.
