Dude that’s awesome! Welcome! I don’t think I’ve ever met someone from Brazil who has seen Tenchi! Did you have a Portugese dub when you watched it on TV? Or English, Spanish, or Japanese with subtitles?
Here we had the good Brazilian Portuguese dub in the first two OVAs(who was displayed only one time with heavy censorship and thanks to a lawsuit), Tenchi Universe! and Tenchi in Tokyo!. Unfortunately, I’ve only had the oportunity to watch the last two series until 2005, when they ended the transmission of the anime.
