Yui has dark blue hair tied into two braids that she leaves resting over her shoulders. She has pink eyes with glasses. She is mostly seen in her school uniform. Her formal clothes consist of a yellow hat, light blue shirt over a yellow one and light brown skirt. In the summer, she wears a short-sleeved mint green blouse and light yellow shorts.
Yui seems to be very friendly as she meets a 13-year-old girl named Nakamura Kazumi and adopts her as her younger sister. She also has a talent for art as her dream is to make a best selling picture book.
Meeting Haruka and Becoming the First Target
When Haruka arrives at Noble Academy, Yui appears and shows her around. Haruka goes into the forest and Yui follows her, only for Close, one of the generals of Dys Dark, to lock her dream of being an author away and create a Zetsuborg. She is soon freed after Haruka, who transformed into Cure Flora, purified it.
