Serena is Sailor Moon. She is the first of the warriors. She is discovered by Luna. Serena may be a crybaby, whiner, failure, and clutzy-but she is true to her friends. When it comes to her weaknesses(acting as an crybaby & things related), you have to think of how hard it is when you already have difficulties, and to find out you have to defend the univese and had another life it's hard!
