"I remember when I look at the fog..." thinks Minako. "My still young planet, covered in the fog of thick sulfuric acid from the volcanic activity. Surrounded by the sulfur fog, my Magellan Castle. And the beautiful morning glow of my other planet..."- Code Name Wa: SailorV manga (thanks to Alex Glover)

Although the senshi were formally introduced as princesses in the later part of the manga (act volume), Minako-chan already knew that she was Princess Venus in the SailorV manga.

When Artemis told her of her real identity, she found it hard to believe thinking that she was just an ordinary teenager, how then could she be of royal blood? But then, Artemis informed her that the Aino Minako that she is now, is an incarnation of the goddess Venus.

At first, Artemis was rather surprised that the incarnation of the beautiful goddess would turn out to be the rather "unlady-like" Minako-chan. He often complained to "the Boss" since Minako-chan was hard to train and sometimes, even, she had second thoughts about being a sailor senshi. But then, Artemis could not deny at all that she also displayed characteristics from Venus. One time, when he peeked at Minako while she was bathing (he later got a scratch from Luna, don't worry), he saw for himself just how beautiful she was becoming. She looked more like the goddess herself. So, how can you deny that she is a princess and of royal blood? Can you say that a princess can just be the "delicate" type? Guess Venus was that and more...

Another information about the Princess was that she had a Guardian fairy, whom she is holding at the picture at the right. In the manga, their Guardian Fairies first appeared in Act 41, when the senshi transformed into their princess forms. The Guardian Fairies told them to ask for power from their palaces to give to the Holy Grail. Their power enabled them to destroy Neherenia and Zirconia completely. Besides Princess Serenity, the other senshi proved themselves to be worthy princesses of their planets. Other than that, we can clearly see for ourselves just how beautiful they were, ne? Venus' beauty is not just because she was an incarnation of a goddess but because of the light inside of her that brings out her natural beauty.
