Kei Yonagi 夜凪景
Height 168 cm
Affiliation Studio Daikokuten
A high school girl who's all alone to raise her twin siblings, Rui and Rei, ever since their mother died and their father left home. Her greatest talent is acting; however, her very immersive approach, based on her own intimate memories, leads her to often get lost in character and blur the line between fiction and reality.
