Although there is a way to write Ayu's first name in Kanji, I remember reading that she prefers writing it in Hiragana. Her last name consists of the characters "Hama" and "Saki", which I tried translating with an online translator:
‚_‚ä‚Ý <--walking
‚͂܂³‚« <--Ahead ‚Ü
most likely not the exact meanings, but I'm sure someone like Masa would be able to help with this more than I could
