Yumesaki, Tiara

夢咲ティアラ

She serves as the headmistress of Dream Academy and is the older sister of Naoto Suzukawa. Tiara Yumesaki is actually a stage name, while Tiara Suzukawa is her real name.
During her college years, Tiara worked as a member of Masquerade's staff. Like many others, she was amazed by the idol duo, but she often overheard girls saying they wanted to become idols yet wouldn't pursue it. This struck a chord with Tiara, making her wonder why these girls would give up before even trying.
Some time after Masquerade disbanded and Orihime was settling in as Starlight's new headmistress, Tiara went to visit her. She noted the large number of applicants, and Orihime stated that while there were so many, only a few would get in. Feeling bad that the girls who wouldn't make it would have to give up on their dreams, Tiara decided to create her own idol school that would offer alternative pathways.
It took her less than 10 years to create Dream Academy. Her policy states that "If you have the passion, anyone can be an idol", making Dream Academy more open to receiving students than most idol academies.
