Ecchi can be translated into Finnish in many ways, perhaps "indecent" or "indecent" could be suitable translations.
In anime, as a concept, it is not a category per se, but a matter of pleasing the viewers, but in this context, it is wisest in the lists to completely separate the series that include brisk nudity into their own compartment - series where the body of a woman or man is emphasized more than the traditional "swimsuit/beach episode fanservice".
However, these series, whose narrative style strongly colors the general perception of anime, should not be confused with the Hentai category, there is still a long way to go. Of course shorter than some than others. The legendary saying “I look at it because of the plot” applies to these series. Most do have a pretty immersive plot, in addition to ecch. TV versions are censored to be suitable for minors, DVD & blu-ray versions are usually uncensored. Choose the option that works best for you when you start watching.

No decent trailer can be found in the series without overly significant plot revelations, however its first episode can be found on youtube. The episode was uploaded to the service in 2012, and we assume that the copyright holder of the series has given tacit consent to its submission because it has not filed a claim for its removal within five years.
