Nozomi Sasaki  

The individual decided to alter her name in the all-hiragana form because the kanji of her birth name was identical to that of voice actor Nozomu Sasaki, which can be pronounced as "Nozomi" or "Nozomu." This change was made due to a coincidence. The source for this information is Ameblo (http://ameblo.jp/19830219/) and Twitter (@nozooooo).
