One kiss.

Quite a bit of nudity and sexual themes in episode 18.

Frenetic science fiction violence, robot gore and intense action sequences.

"Hell", "damn" and "bastard" are used a lot. "s--t" is used once in episode 3.

One robot is often briefly seen smoking.

"Casshern Sins" is an extremely depressing and dramatic animated show, which themes might be disturbing for younger viewers.

The fights tend to get rather intense and explicit.
