Natsuki Mizu (水夏希 Mizu Natsuki, born 1972) is the former top star (otokoyaku) for Snow Troupe of Takarazuka Revue from 12/24/06 to 09/12/10. She joined the company in 1993 and became the top star in December 2006 upon the resignation of Hikaru Asami
She is from Chiba-shi, Chiba-ken and her birthday is August 16.
Her nickname is Mizu and Chika.
Starting her career in the Moon Troupe, she is one of a few current younger and non-Senka members (and also in the roster) that have participated in the performances with all 5 troupes (even it is just a special appearance for Star production of Rose of Versailles). She is one of several promising young stars that were promoted in 1999 (along with Sumire Haruno, the former top star for Flower Troupe and Hikaru Asami, the former top star for Snow Troupe). Before she was promoted to top star, she was considered as one of top-stars-in-waiting along with Kei Takashiro, the former top star for Cosmo Troupe, Kei Aran, the current top star for Star Troupe, Jun Sena, the current top star for Moon Troupe, and Yūga Yamato, the current top star of Cosmo Troupe.
While she was in Moon Troupe, she had already caught the attention, took the title role of Me and My Girl of the first half of the New Actor Production in 1995. In 1996, she was in title role of CAN-CAN. Then she transferred to the Flower Troupe.
Her time in the Flower Troupe is when she most notably developed her skills. Together with Sumire Haruno (class of 1991) and Jun Sena (class of 1992), they formed a tight trio among the younger performers in the Flower Troupe. During those years, she got praises for her performance on the leading role of Yoake no Jokyoku: her first leading role for New Actor production in Flower Troupe. Also she had her first leading show, Romeo and Juliet '99 at the Bow Hall (with Kanami Ayano, retired Top musumeyaku star) in 1999.
