Thank god, the first anime I saw and shown my family was 'Ah! My Goddess!!'.
Why I saw it? Well I new to anime, and just found the downloading site having all anime. In the list of all anime, it was the first 'Ah' comes very early in alphabetical order. I was lucky in that.
I belong to old generation of first time watcher, my first anime were Inuyasha, Fairly Tail, Ah! my goddess, Kitman reborn. "Rosario to Vampire" was my first harem anime. Soon I learned not all anime can be shown to anybody.
