Rozen Maiden: Season 1

If you still want to watch, you can safely start immediately with season 3, where everything repeats itself and it will be more modern.

First impression: the series has an age limit for children under the age of 10

The first impression is this: the series seems to be quite good, but it is clearly designed for lolicon fans, fans of mysticism can also watch it (although not everyone will like it).
