The No. 1 popular cast member at Concept Cafe "Lumière" ♡ A classic idol type with fluffy brown twin-tails and large pink ribbons as her trademark!

Age: 19 Height: 149cm
A little devil-type cast member with eye-catching black hair and red mesh twin-tails ♡ She is skilled at making customers fall into a deep hole with her spoiled, close distance and the way she stares intently.

"Wait, don't I look great today? You made the right choice coming to see me! ♪"
