In the end of the first season, there is a episode where the sailors guardians are killed one by one by the villainesses squads, it was quite exciting for me to watch for the first time beautiful superheroines killed and their demises. Only left the main character Sailor Moon. This is the deaths scenes of the sailor guardians in this episode :
It was a long time ago so I can't remember the storyline completely. I remember some of the episodes, some were very exciting, some not. Sometimes the sailor heroines were in huge peril with little ero/gore elements in it, and sometimes they were purely killed with the death ending I love to watch (In that time I was a child so it didn't turn me on like now), it was very surprising in that time to have anime for children with explicit/ero/gore contents !
If someone has more knowledge about this anime serie, feel free to post materials here...
