I’m trying to find an anime I saw on Mangas Channel in Hotbird Satellite before 2006, I think it was a trailer.
I remember watching a boy in the street that notices a young girl (she could be an alien or an angel) walking naked with a thick bracelet on her wrist or maybe it was a collar on her neck, definitely had an inscription on it that sort of looked like a triangle if I remember well and I also remember him saving her from being hit by a truck.
