In 1998, she founded Cosmos Troupe with Asato Shizuki, Yōka Wao, Wataru Kozuki and Hikaru Asami with an overseas performance in Hong Kong.
Although she had participated as a guest star in a couple of performances with other Japanese artists, there was no official announcements as to what Hanafusa's future career direction will be until June 2012.
Thus she was an Elisabeth who was haunted by two deaths (Maki Ichiro and Asato Shizuki), married to two Franz Josephs (Fubuki Takane and Yōka Wao), assassinated by two Luigi Luchenis (Yū Todoroki and Wataru Kozuki).
She crowned four Prince Rudolfs (Tatsuki Kōju, Yōka Wao, Hikaru Asami and Sakiho Juri) because Kōju and Asami changed troupes before the Tokyo performance and were substituted by Wao and Juri.
Most of the actresses playing Franz Josephs, Rudolfs and Luigis became stars later on, except Juri, who was moved to Senka.
